@@ + + OpenSSL CHANGES + _______________ + + This is a high-level summary of the most important changes. + For a full list of changes, see the git commit log; for example, + https://github.com/openssl/openssl/commits/ and pick the appropriate + release branch. + + Changes between 1.0.2r and 1.0.2s [28 May 2019] + + *) Change the default RSA, DSA and DH size to 2048 bit instead of 1024. + This changes the size when using the genpkey app when no size is given. It + fixes an omission in earlier changes that changed all RSA, DSA and DH + generation apps to use 2048 bits by default. + [Kurt Roeckx] + + *) Add FIPS support for Android Arm 64-bit + + Support for Android Arm 64-bit was added to the OpenSSL FIPS Object + Module in Version 2.0.10. For some reason, the corresponding target + 'android64-aarch64' was missing OpenSSL 1.0.2, whence it could not be + built with FIPS support on Android Arm 64-bit. This omission has been + fixed. + [Matthias St. Pierre] + + Changes between 1.0.2q and 1.0.2r [26 Feb 2019] + + *) 0-byte record padding oracle + + If an application encounters a fatal protocol error and then calls + SSL_shutdown() twice (once to send a close_notify, and once to receive one) + then OpenSSL can respond differently to the calling application if a 0 byte + record is received with invalid padding compared to if a 0 byte record is + received with an invalid MAC. If the application then behaves differently + based on that in a way that is detectable to the remote peer, then this + amounts to a padding oracle that could be used to decrypt data. + + In order for this to be exploitable "non-stitched" ciphersuites must be in + use. Stitched ciphersuites are optimised implementations of certain + commonly used ciphersuites. Also the application must call SSL_shutdown() + twice even if a protocol error has occurred (applications should not do + this but some do anyway). + + This issue was discovered by Juraj Somorovsky, Robert Merget and Nimrod + Aviram, with additional investigation by Steven Collison and Andrew + Hourselt. It was reported to OpenSSL on 10th December 2018. + (CVE-2019-1559) + [Matt Caswell] + + *) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0(). + [Richard Levitte] + + Changes between 1.0.2p and 1.0.2q [20 Nov 2018] + + *) Microarchitecture timing vulnerability in ECC scalar multiplication + + OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been + shown to be vulnerable to a microarchitecture timing side channel attack. + An attacker with sufficient access to mount local timing attacks during + ECDSA signature generation could recover the private key. + + This issue was reported to OpenSSL on 26th October 2018 by Alejandro + Cabrera Aldaya, Billy Brumley, Sohaib ul Hassan, Cesar Pereida Garcia and + Nicola Tuveri. + (CVE-2018-5407) + [Billy Brumley] + + *) Timing vulnerability in DSA signature generation + + The OpenSSL DSA signature algorithm has been shown to be vulnerable to a + timing side channel attack. An attacker could use variations in the signing + algorithm to recover the private key. + + This issue was reported to OpenSSL on 16th October 2018 by Samuel Weiser. + (CVE-2018-0734) + [Paul Dale] + + *) Resolve a compatibility issue in EC_GROUP handling with the FIPS Object + Module, accidentally introduced while backporting security fixes from the + development branch and hindering the use of ECC in FIPS mode. + [Nicola Tuveri] + + Changes between 1.0.2o and 1.0.2p [14 Aug 2018] + + *) Client DoS due to large DH parameter + + During key agreement in a TLS handshake using a DH(E) based ciphersuite a + malicious server can send a very large prime value to the client. This will + cause the client to spend an unreasonably long period of time generating a + key for this prime resulting in a hang until the client has finished. This + could be exploited in a Denial Of Service attack. + + This issue was reported to OpenSSL on 5th June 2018 by Guido Vranken + (CVE-2018-0732) + [Guido Vranken] + + *) Cache timing vulnerability in RSA Key Generation + + The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to + a cache timing side channel attack. An attacker with sufficient access to + mount cache timing attacks during the RSA key generation process could + recover the private key. + + This issue was reported to OpenSSL on 4th April 2018 by Alejandro Cabrera + Aldaya, Billy Brumley, Cesar Pereida Garcia and Luis Manuel Alvarez Tapia. + (CVE-2018-0737) + [Billy Brumley] + + *) Make EVP_PKEY_asn1_new() a bit stricter about its input. A NULL pem_str + parameter is no longer accepted, as it leads to a corrupt table. NULL + pem_str is reserved for alias entries only. + [Richard Levitte] + + *) Revert blinding in ECDSA sign and instead make problematic addition + length-invariant. Switch even to fixed-length Montgomery multiplication. + [Andy Polyakov] + + *) Change generating and checking of primes so that the error rate of not + being prime depends on the intended use based on the size of the input. + For larger primes this will result in more rounds of Miller-Rabin. + The maximal error rate for primes with more than 1080 bits is lowered + to 2^-128. + [Kurt Roeckx, Annie Yousar] + + *) Increase the number of Miller-Rabin rounds for DSA key generating to 64. + [Kurt Roeckx] + + *) Add blinding to ECDSA and DSA signatures to protect against side channel + attacks discovered by Keegan Ryan (NCC Group). + [Matt Caswell] + + *) When unlocking a pass phrase protected PEM file or PKCS#8 container, we + now allow empty (zero character) pass phrases. + [Richard Levitte] + + *) Certificate time validation (X509_cmp_time) enforces stricter + compliance with RFC 5280. Fractional seconds and timezone offsets + are no longer allowed. + [Emilia Käsper] + + Changes between 1.0.2n and 1.0.2o [27 Mar 2018] + + *) Constructed ASN.1 types with a recursive definition could exceed the stack + + Constructed ASN.1 types with a recursive definition (such as can be found + in PKCS7) could eventually exceed the stack given malicious input with + excessive recursion. This could result in a Denial Of Service attack. There + are no such structures used within SSL/TLS that come from untrusted sources + so this is considered safe. + + This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz + project. + (CVE-2018-0739) + [Matt Caswell] + + Changes between 1.0.2m and 1.0.2n [7 Dec 2017] + + *) Read/write after SSL object in error state + + OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" + mechanism. The intent was that if a fatal error occurred during a handshake + then OpenSSL would move into the error state and would immediately fail if + you attempted to continue the handshake. This works as designed for the + explicit handshake functions (SSL_do_handshake(), SSL_accept() and + SSL_connect()), however due to a bug it does not work correctly if + SSL_read() or SSL_write() is called directly. In that scenario, if the + handshake fails then a fatal error will be returned in the initial function + call. If SSL_read()/SSL_write() is subsequently called by the application + for the same SSL object then it will succeed and the data is passed without + being decrypted/encrypted directly from the SSL/TLS record layer. + + In order to exploit this issue an application bug would have to be present + that resulted in a call to SSL_read()/SSL_write() being issued after having + already received a fatal error. + + This issue was reported to OpenSSL by David Benjamin (Google). + (CVE-2017-3737) + [Matt Caswell] + + *) rsaz_1024_mul_avx2 overflow bug on x86_64 + + There is an overflow bug in the AVX2 Montgomery multiplication procedure + used in exponentiation with 1024-bit moduli. No EC algorithms are affected. + Analysis suggests that attacks against RSA and DSA as a result of this + defect would be very difficult to perform and are not believed likely. + Attacks against DH1024 are considered just feasible, because most of the + work necessary to deduce information about a private key may be performed + offline. The amount of resources required for such an attack would be + significant. However, for an attack on TLS to be meaningful, the server + would have to share the DH1024 private key among multiple clients, which is + no longer an option since CVE-2016-0701. + + This only affects processors that support the AVX2 but not ADX extensions + like Intel Haswell (4th generation). + + This issue was reported to OpenSSL by David Benjamin (Google). The issue + was originally found via the OSS-Fuzz project. + (CVE-2017-3738) + [Andy Polyakov] + + Changes between 1.0.2l and 1.0.2m [2 Nov 2017] + + *) bn_sqrx8x_internal carry bug on x86_64 + + There is a carry propagating bug in the x86_64 Montgomery squaring + procedure. No EC algorithms are affected. Analysis suggests that attacks + against RSA and DSA as a result of this defect would be very difficult to + perform and are not believed likely. Attacks against DH are considered just + feasible (although very difficult) because most of the work necessary to + deduce information about a private key may be performed offline. The amount + of resources required for such an attack would be very significant and + likely only accessible to a limited number of attackers. An attacker would + additionally need online access to an unpatched system using the target + private key in a scenario with persistent DH parameters and a private + key that is shared between multiple clients. + + This only affects processors that support the BMI1, BMI2 and ADX extensions + like Intel Broadwell (5th generation) and later or AMD Ryzen. + + This issue was reported to OpenSSL by the OSS-Fuzz project. + (CVE-2017-3736) + [Andy Polyakov] + + *) Malformed X.509 IPAddressFamily could cause OOB read + + If an X.509 certificate has a malformed IPAddressFamily extension, + OpenSSL could do a one-byte buffer overread. The most likely result + would be an erroneous display of the certificate in text format. + + This issue was reported to OpenSSL by the OSS-Fuzz project. + (CVE-2017-3735) + [Rich Salz] + + Changes between 1.0.2k and 1.0.2l [25 May 2017] + + *) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target + platform rather than 'mingw'. + [Richard Levitte] + + Changes between 1.0.2j and 1.0.2k [26 Jan 2017] + + *) Truncated packet could crash via OOB read + + If one side of an SSL/TLS path is running on a 32-bit host and a specific + cipher is being used, then a truncated packet can cause that host to + perform an out-of-bounds read, usually resulting in a crash. + + This issue was reported to OpenSSL by Robert Święcki of Google. + (CVE-2017-3731) + [Andy Polyakov] + + *) BN_mod_exp may produce incorrect results on x86_64 + + There is a carry propagating bug in the x86_64 Montgomery squaring + procedure. No EC algorithms are affected. Analysis suggests that attacks + against RSA and DSA as a result of this defect would be very difficult to + perform and are not believed likely. Attacks against DH are considered just + feasible (although very difficult) because most of the work necessary to + deduce information about a private key may be performed offline. The amount + of resources required for such an attack would be very significant and + likely only accessible to a limited number of attackers. An attacker would + additionally need online access to an unpatched system using the target + private key in a scenario with persistent DH parameters and a private + key that is shared between multiple clients. For example this can occur by + default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very + similar to CVE-2015-3193 but must be treated as a separate problem. + + This issue was reported to OpenSSL by the OSS-Fuzz project. + (CVE-2017-3732) + [Andy Polyakov] + + *) Montgomery multiplication may produce incorrect results + + There is a carry propagating bug in the Broadwell-specific Montgomery + multiplication procedure that handles input lengths divisible by, but + longer than 256 bits. Analysis suggests that attacks against RSA, DSA + and DH private keys are impossible. This is because the subroutine in + question is not used in operations with the private key itself and an input + of the attacker's direct choice. Otherwise the bug can manifest itself as + transient authentication and key negotiation failures or reproducible + erroneous outcome of public-key operations with specially crafted input. + Among EC algorithms only Brainpool P-512 curves are affected and one + presumably can attack ECDH key negotiation. Impact was not analyzed in + detail, because pre-requisites for attack are considered unlikely. Namely + multiple clients have to choose the curve in question and the server has to + share the private key among them, neither of which is default behaviour. + Even then only clients that chose the curve will be affected. + + This issue was publicly reported as transient failures and was not + initially recognized as a security issue. Thanks to Richard Morgan for + providing reproducible case. + (CVE-2016-7055) + [Andy Polyakov] + + *) OpenSSL now fails if it receives an unrecognised record type in TLS1.0 + or TLS1.1. Previously this only happened in SSLv3 and TLS1.2. This is to + prevent issues where no progress is being made and the peer continually + sends unrecognised record types, using up resources processing them. + [Matt Caswell] + + Changes between 1.0.2i and 1.0.2j [26 Sep 2016] + + *) Missing CRL sanity check + + A bug fix which included a CRL sanity check was added to OpenSSL 1.1.0 + but was omitted from OpenSSL 1.0.2i. As a result any attempt to use + CRLs in OpenSSL 1.0.2i will crash with a null pointer exception. + + This issue only affects the OpenSSL 1.0.2i + (CVE-2016-7052) + [Matt Caswell] + + Changes between 1.0.2h and 1.0.2i [22 Sep 2016] + + *) OCSP Status Request extension unbounded memory growth + + A malicious client can send an excessively large OCSP Status Request + extension. If that client continually requests renegotiation, sending a + large OCSP Status Request extension each time, then there will be unbounded + memory growth on the server. This will eventually lead to a Denial Of + Service attack through memory exhaustion. Servers with a default + configuration are vulnerable even if they do not support OCSP. Builds using + the "no-ocsp" build time option are not affected. + + This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) + (CVE-2016-6304) + [Matt Caswell] + + *) In order to mitigate the SWEET32 attack, the DES ciphers were moved from + HIGH to MEDIUM. + + This issue was reported to OpenSSL Karthikeyan Bhargavan and Gaetan + Leurent (INRIA) + (CVE-2016-2183) + [Rich Salz] + + *) OOB write in MDC2_Update() + + An overflow can occur in MDC2_Update() either if called directly or + through the EVP_DigestUpdate() function using MDC2. If an attacker + is able to supply very large amounts of input data after a previous + call to EVP_EncryptUpdate() with a partial block then a length check + can overflow resulting in a heap corruption. + + The amount of data needed is comparable to SIZE_MAX which is impractical + on most platforms. + + This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) + (CVE-2016-6303) + [Stephen Henson] + + *) Malformed SHA512 ticket DoS + + If a server uses SHA512 for TLS session ticket HMAC it is vulnerable to a + DoS attack where a malformed ticket will result in an OOB read which will + ultimately crash. + + The use of SHA512 in TLS session tickets is comparatively rare as it requires + a custom server callback and ticket lookup mechanism. + + This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) + (CVE-2016-6302) + [Stephen Henson] + + *) OOB write in BN_bn2dec() + + The function BN_bn2dec() does not check the return value of BN_div_word(). + This can cause an OOB write if an application uses this function with an + overly large BIGNUM. This could be a problem if an overly large certificate + or CRL is printed out from an untrusted source. TLS is not affected because + record limits will reject an oversized certificate before it is parsed. + + This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) + (CVE-2016-2182) + [Stephen Henson] + + *) OOB read in TS_OBJ_print_bio() + + The function TS_OBJ_print_bio() misuses OBJ_obj2txt(): the return value is + the total length the OID text representation would use and not the amount + of data written. This will result in OOB reads when large OIDs are + presented. + + This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) + (CVE-2016-2180) + [Stephen Henson] + + *) Pointer arithmetic undefined behaviour + + Avoid some undefined pointer arithmetic + + A common idiom in the codebase is to check limits in the following manner: + "p + len > limit" + + Where "p" points to some malloc'd data of SIZE bytes and + limit == p + SIZE + + "len" here could be from some externally supplied data (e.g. from a TLS + message). + + The rules of C pointer arithmetic are such that "p + len" is only well + defined where len <= SIZE. Therefore the above idiom is actually + undefined behaviour. + + For example this could cause problems if some malloc implementation + provides an address for "p" such that "p + len" actually overflows for + values of len that are too big and therefore p + len < limit. + + This issue was reported to OpenSSL by Guido Vranken + (CVE-2016-2177) + [Matt Caswell] + + *) Constant time flag not preserved in DSA signing + + Operations in the DSA signing algorithm should run in constant time in + order to avoid side channel attacks. A flaw in the OpenSSL DSA + implementation means that a non-constant time codepath is followed for + certain operations. This has been demonstrated through a cache-timing + attack to be sufficient for an attacker to recover the private DSA key. + + This issue was reported by César Pereida (Aalto University), Billy Brumley + (Tampere University of Technology), and Yuval Yarom (The University of + Adelaide and NICTA). + (CVE-2016-2178) + [César Pereida] + + *) DTLS buffered message DoS + + In a DTLS connection where handshake messages are delivered out-of-order + those messages that OpenSSL is not yet ready to process will be buffered + for later use. Under certain circumstances, a flaw in the logic means that + those messages do not get removed from the buffer even though the handshake + has been completed. An attacker could force up to approx. 15 messages to + remain in the buffer when they are no longer required. These messages will + be cleared when the DTLS connection is closed. The default maximum size for + a message is 100k. Therefore the attacker could force an additional 1500k + to be consumed per connection. By opening many simulataneous connections an + attacker could cause a DoS attack through memory exhaustion. + + This issue was reported to OpenSSL by Quan Luo. + (CVE-2016-2179) + [Matt Caswell] + + *) DTLS replay protection DoS + + A flaw in the DTLS replay attack protection mechanism means that records + that arrive for future epochs update the replay protection "window" before + the MAC for the record has been validated. This could be exploited by an + attacker by sending a record for the next epoch (which does not have to + decrypt or have a valid MAC), with a very large sequence number. This means + that all subsequent legitimate packets are dropped causing a denial of + service for a specific DTLS connection. + + This issue was reported to OpenSSL by the OCAP audit team. + (CVE-2016-2181) + [Matt Caswell] + + *) Certificate message OOB reads + + In OpenSSL 1.0.2 and earlier some missing message length checks can result + in OOB reads of up to 2 bytes beyond an allocated buffer. There is a + theoretical DoS risk but this has not been observed in practice on common + platforms. + + The messages affected are client certificate, client certificate request + and server certificate. As a result the attack can only be performed + against a client or a server which enables client authentication. + + This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) + (CVE-2016-6306) + [Stephen Henson] + + Changes between 1.0.2g and 1.0.2h [3 May 2016] + + *) Prevent padding oracle in AES-NI CBC MAC check + + A MITM attacker can use a padding oracle attack to decrypt traffic + when the connection uses an AES CBC cipher and the server support + AES-NI. + + This issue was introduced as part of the fix for Lucky 13 padding + attack (CVE-2013-0169). The padding check was rewritten to be in + constant time by making sure that always the same bytes are read and + compared against either the MAC or padding bytes. But it no longer + checked that there was enough data to have both the MAC and padding + bytes. + + This issue was reported by Juraj Somorovsky using TLS-Attacker. + (CVE-2016-2107) + [Kurt Roeckx] + + *) Fix EVP_EncodeUpdate overflow + + An overflow can occur in the EVP_EncodeUpdate() function which is used for + Base64 encoding of binary data. If an attacker is able to supply very large + amounts of input data then a length check can overflow resulting in a heap + corruption. + + Internally to OpenSSL the EVP_EncodeUpdate() function is primarly used by + the PEM_write_bio* family of functions. These are mainly used within the + OpenSSL command line applications, so any application which processes data + from an untrusted source and outputs it as a PEM file should be considered + vulnerable to this issue. User applications that call these APIs directly + with large amounts of untrusted data may also be vulnerable. + + This issue was reported by Guido Vranken. + (CVE-2016-2105) + [Matt Caswell] + + *) Fix EVP_EncryptUpdate overflow + + An overflow can occur in the EVP_EncryptUpdate() function. If an attacker + is able to supply very large amounts of input data after a previous call to + EVP_EncryptUpdate() with a partial block then a length check can overflow + resulting in a heap corruption. Following an analysis of all OpenSSL + internal usage of the EVP_EncryptUpdate() function all usage is one of two + forms. The first form is where the EVP_EncryptUpdate() call is known to be + the first called function after an EVP_EncryptInit(), and therefore that + specific call must be safe. The second form is where the length passed to + EVP_EncryptUpdate() can be seen from the code to be some small value and + therefore there is no possibility of an overflow. Since all instances are + one of these two forms, it is believed that there can be no overflows in + internal code due to this problem. It should be noted that + EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths. + Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances + of these calls have also been analysed too and it is believed there are no + instances in internal usage where an overflow could occur. + + This issue was reported by Guido Vranken. + (CVE-2016-2106) + [Matt Caswell] + + *) Prevent ASN.1 BIO excessive memory allocation + + When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio() + a short invalid encoding can casuse allocation of large amounts of memory + potentially consuming excessive resources or exhausting memory. + + Any application parsing untrusted data through d2i BIO functions is + affected. The memory based functions such as d2i_X509() are *not* affected. + Since the memory based functions are used by the TLS library, TLS + applications are not affected. + + This issue was reported by Brian Carpenter. + (CVE-2016-2109) + [Stephen Henson] + + *) EBCDIC overread + + ASN1 Strings that are over 1024 bytes can cause an overread in applications + using the X509_NAME_oneline() function on EBCDIC systems. This could result + in arbitrary stack data being returned in the buffer. + + This issue was reported by Guido Vranken. + (CVE-2016-2176) + [Matt Caswell] + + *) Modify behavior of ALPN to invoke callback after SNI/servername + callback, such that updates to the SSL_CTX affect ALPN. + [Todd Short] + + *) Remove LOW from the DEFAULT cipher list. This removes singles DES from the + default. + [Kurt Roeckx] + + *) Only remove the SSLv2 methods with the no-ssl2-method option. When the + methods are enabled and ssl2 is disabled the methods return NULL. + [Kurt Roeckx] + + Changes between 1.0.2f and 1.0.2g [1 Mar 2016] + + * Disable weak ciphers in SSLv3 and up in default builds of OpenSSL. + Builds that are not configured with "enable-weak-ssl-ciphers" will not + provide any "EXPORT" or "LOW" strength ciphers. + [Viktor Dukhovni] + + * Disable SSLv2 default build, default negotiation and weak ciphers. SSLv2 + is by default disabled at build-time. Builds that are not configured with + "enable-ssl2" will not support SSLv2. Even if "enable-ssl2" is used, + users who want to negotiate SSLv2 via the version-flexible SSLv23_method() + will need to explicitly call either of: + + SSL_CTX_clear_options(ctx, SSL_OP_NO_SSLv2); + or + SSL_clear_options(ssl, SSL_OP_NO_SSLv2); + + as appropriate. Even if either of those is used, or the application + explicitly uses the version-specific SSLv2_method() or its client and + server variants, SSLv2 ciphers vulnerable to exhaustive search key + recovery have been removed. Specifically, the SSLv2 40-bit EXPORT + ciphers, and SSLv2 56-bit DES are no longer available. + (CVE-2016-0800) + [Viktor Dukhovni] + + *) Fix a double-free in DSA code + + A double free bug was discovered when OpenSSL parses malformed DSA private + keys and could lead to a DoS attack or memory corruption for applications + that receive DSA private keys from untrusted sources. This scenario is + considered rare. + + This issue was reported to OpenSSL by Adam Langley(Google/BoringSSL) using + libFuzzer. + (CVE-2016-0705) + [Stephen Henson] + + *) Disable SRP fake user seed to address a server memory leak. + + Add a new method SRP_VBASE_get1_by_user that handles the seed properly. + + SRP_VBASE_get_by_user had inconsistent memory management behaviour. + In order to fix an unavoidable memory leak, SRP_VBASE_get_by_user + was changed to ignore the "fake user" SRP seed, even if the seed + is configured. + + Users should use SRP_VBASE_get1_by_user instead. Note that in + SRP_VBASE_get1_by_user, caller must free the returned value. Note + also that even though configuring the SRP seed attempts to hide + invalid usernames by continuing the handshake with fake + credentials, this behaviour is not constant time and no strong + guarantees are made that the handshake is indistinguishable from + that of a valid user. + (CVE-2016-0798) + [Emilia Käsper] + + *) Fix BN_hex2bn/BN_dec2bn NULL pointer deref/heap corruption + + In the BN_hex2bn function the number of hex digits is calculated using an + int value |i|. Later |bn_expand| is called with a value of |i * 4|. For + large values of |i| this can result in |bn_expand| not allocating any + memory because |i * 4| is negative. This can leave the internal BIGNUM data + field as NULL leading to a subsequent NULL ptr deref. For very large values + of |i|, the calculation |i * 4| could be a positive value smaller than |i|. + In this case memory is allocated to the internal BIGNUM data field, but it + is insufficiently sized leading to heap corruption. A similar issue exists + in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn + is ever called by user applications with very large untrusted hex/dec data. + This is anticipated to be a rare occurrence. + + All OpenSSL internal usage of these functions use data that is not expected + to be untrusted, e.g. config file data or application command line + arguments. If user developed applications generate config file data based + on untrusted data then it is possible that this could also lead to security + consequences. This is also anticipated to be rare. + + This issue was reported to OpenSSL by Guido Vranken. + (CVE-2016-0797) + [Matt Caswell] + + *) Fix memory issues in BIO_*printf functions + + The internal |fmtstr| function used in processing a "%s" format string in + the BIO_*printf functions could overflow while calculating the length of a + string and cause an OOB read when printing very long strings. + + Additionally the internal |doapr_outch| function can attempt to write to an + OOB memory location (at an offset from the NULL pointer) in the event of a + memory allocation failure. In 1.0.2 and below this could be caused where + the size of a buffer to be allocated is greater than INT_MAX. E.g. this + could be in processing a very long "%s" format string. Memory leaks can + also occur. + + The first issue may mask the second issue dependent on compiler behaviour. + These problems could enable attacks where large amounts of untrusted data + is passed to the BIO_*printf functions. If applications use these functions + in this way then they could be vulnerable. OpenSSL itself uses these + functions when printing out human-readable dumps of ASN.1 data. Therefore + applications that print this data could be vulnerable if the data is from + untrusted sources. OpenSSL command line applications could also be + vulnerable where they print out ASN.1 data, or if untrusted data is passed + as command line arguments. + + Libssl is not considered directly vulnerable. Additionally certificates etc + received via remote connections via libssl are also unlikely to be able to + trigger these issues because of message size limits enforced within libssl. + + This issue was reported to OpenSSL Guido Vranken. + (CVE-2016-0799) + [Matt Caswell] + + *) Side channel attack on modular exponentiation + + A side-channel attack was found which makes use of cache-bank conflicts on + the Intel Sandy-Bridge microarchitecture which could lead to the recovery + of RSA keys. The ability to exploit this issue is limited as it relies on + an attacker who has control of code in a thread running on the same + hyper-threaded core as the victim thread which is performing decryptions. + + This issue was reported to OpenSSL by Yuval Yarom, The University of + Adelaide and NICTA, Daniel Genkin, Technion and Tel Aviv University, and + Nadia Heninger, University of Pennsylvania with more information at + http://cachebleed.info. + (CVE-2016-0702) + [Andy Polyakov] + + *) Change the req app to generate a 2048-bit RSA/DSA key by default, + if no keysize is specified with default_bits. This fixes an + omission in an earlier change that changed all RSA/DSA key generation + apps to use 2048 bits by default. + [Emilia Käsper] + + Changes between 1.0.2e and 1.0.2f [28 Jan 2016] + + *) DH small subgroups + + Historically OpenSSL only ever generated DH parameters based on "safe" + primes. More recently (in version 1.0.2) support was provided for + generating X9.42 style parameter files such as those required for RFC 5114 + support. The primes used in such files may not be "safe". Where an + application is using DH configured with parameters based on primes that are + not "safe" then an attacker could use this fact to find a peer's private + DH exponent. This attack requires that the attacker complete multiple + handshakes in which the peer uses the same private DH exponent. For example + this could be used to discover a TLS server's private DH exponent if it's + reusing the private DH exponent or it's using a static DH ciphersuite. + + OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in + TLS. It is not on by default. If the option is not set then the server + reuses the same private DH exponent for the life of the server process and + would be vulnerable to this attack. It is believed that many popular + applications do set this option and would therefore not be at risk. + + The fix for this issue adds an additional check where a "q" parameter is + available (as is the case in X9.42 based parameters). This detects the + only known attack, and is the only possible defense for static DH + ciphersuites. This could have some performance impact. + + Additionally the SSL_OP_SINGLE_DH_USE option has been switched on by + default and cannot be disabled. This could have some performance impact. + + This issue was reported to OpenSSL by Antonio Sanso (Adobe). + (CVE-2016-0701) + [Matt Caswell] + + *) SSLv2 doesn't block disabled ciphers + + A malicious client can negotiate SSLv2 ciphers that have been disabled on + the server and complete SSLv2 handshakes even if all SSLv2 ciphers have + been disabled, provided that the SSLv2 protocol was not also disabled via + SSL_OP_NO_SSLv2. + + This issue was reported to OpenSSL on 26th December 2015 by Nimrod Aviram + and Sebastian Schinzel. + (CVE-2015-3197) + [Viktor Dukhovni] + + *) Reject DH handshakes with parameters shorter than 1024 bits. + [Kurt Roeckx] + + Changes between 1.0.2d and 1.0.2e [3 Dec 2015] + + *) BN_mod_exp may produce incorrect results on x86_64 + + There is a carry propagating bug in the x86_64 Montgomery squaring + procedure.

The amount + of resources required for such an attack would be very significant and + likely only accessible to a limited number of attackers.

WARNING: applications which + included workarounds for the old buggy behaviour will need to be modified + or they could free up already freed BIOs. + [Steve Henson] + + *) Extend the uni2asc/asc2uni => OPENSSL_uni2asc/OPENSSL_asc2uni + renaming to all platforms (within the 0.9.8 branch, this was + done conditionally on Netware platforms to avoid a name clash). + [Guenter ] + + *) Add ECDHE and PSK support to DTLS. + [Michael Tuexen ] + + *) Add CHECKED_STACK_OF macro to safestack.h, otherwise safestack can't + be used on C++. + [Steve Henson] + + *) Add "missing" function EVP_MD_flags() (without this the only way to + retrieve a digest flags is by accessing the structure directly.

So now + you can do: + + openssl sha256 foo + + as well as: + + openssl dgst -sha256 foo + + and this works for ENGINE based algorithms too. + + [Steve Henson] + + *) Update Gost ENGINE to support parameter files. + [Victor B. Wagner ] + + *) Support GeneralizedTime in ca utility. + [Oliver Martin , Steve Henson] + + *) Enhance the hash format used for certificate directory links. The new + form uses the canonical encoding (meaning equivalent names will work + even if they aren't identical) and uses SHA1 instead of MD5.

This avoids any issues with OS routines such + as the year 2038 bug. New *_adj() functions for ASN1 time structures + and X509_time_adj_ex() to cover the extended range. The existing + X509_time_adj() is still usable and will no longer have any date issues. + [Steve Henson] + + *) Delta CRL support. New use deltas option which will attempt to locate + and search any appropriate delta CRLs available. + + This work was sponsored by Google. + [Steve Henson] + + *) Support for CRLs partitioned by reason code. Reorganise CRL processing + code and add additional score elements. Validate alternate CRL paths + as part of the CRL checking and indicate a new error "CRL path validation + error" in this case. Applications wanting additional details can use + the verify callback and check the new "parent" field. If this is not + NULL CRL path validation is taking place.

DN, email, DNS + and URI types are currently supported. + + This work was sponsored by Google. + [Steve Henson] + + *) To cater for systems that provide a pointer-based thread ID rather + than numeric, deprecate the current numeric thread ID mechanism and + replace it with a structure and associated callback type. This + mechanism allows a numeric "hash" to be extracted from a thread ID in + either case, and on platforms where pointers are larger than 'long', + mixing is done to help ensure the numeric 'hash' is usable even if it + can't be guaranteed unique. The default mechanism is to use "&errno" + as a pointer-based thread ID to distinguish between threads. + + Applications that want to provide their own thread IDs should now use + CRYPTO_THREADID_set_callback() to register a callback that will call + either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer(). + + Note that ERR_remove_state() is now deprecated, because it is tied + to the assumption that thread IDs are numeric. ERR_remove_state(0) + to free the current thread's error state should be replaced by + ERR_remove_thread_state(NULL). + + (This new approach replaces the functions CRYPTO_set_idptr_callback(), + CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in + OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an + application was previously providing a numeric thread callback that + was inappropriate for distinguishing threads, then uniqueness might + have been obtained with &errno that happened immediately in the + intermediate development versions of OpenSSL; this is no longer the + case, the numeric thread callback will now override the automatic use + of &errno.) + [Geoff Thorpe, with help from Bodo Moeller] + + *) Initial support for different CRL issuing certificates. This covers a + simple case where the self issued certificates in the chain exist and + the real CRL issuer is higher in the existing chain. + + This work was sponsored by Google. + [Steve Henson] + + *) Removed effectively defunct crypto/store from the build. + [Ben Laurie] + + *) Revamp of STACK to provide stronger type-checking. Still to come: + TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE, + ASN1_STRING, CONF_VALUE. + [Ben Laurie] + + *) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer + RAM on SSL connections.

Still to come: + STACK, TXT_DB, bsearch, qsort. + [Ben Laurie] + + *) Initial support for Cryptographic Message Syntax (aka CMS) based + on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility, + support for data, signedData, compressedData, digestedData and + encryptedData, envelopedData types included. Scripts to check against + RFC4134 examples draft and interop and consistency checks of many + content types and variants. + [Steve Henson] + + *) Add options to enc utility to support use of zlib compression BIO. + [Steve Henson] + + *) Extend mk1mf to support importing of options and assembly language + files from Configure script, currently only included in VC-WIN32. + The assembly language rules can now optionally generate the source + files from the associated perl scripts. + [Steve Henson] + + *) Implement remaining functionality needed to support GOST ciphersuites. + Interop testing has been performed using CryptoPro implementations. + [Victor B. Wagner ] + + *) s390x assembler pack. + [Andy Polyakov] + + *) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU + "family." + [Andy Polyakov] + + *) Implement Opaque PRF Input TLS extension as specified in + draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an + official specification yet and no extension type assignment by + IANA exists, this extension (for now) will have to be explicitly + enabled when building OpenSSL by providing the extension number + to use. For example, specify an option + + -DTLSEXT_TYPE_opaque_prf_input=0x9527 + + to the "config" or "Configure" script to enable the extension, + assuming extension number 0x9527 (which is a completely arbitrary + and unofficial assignment based on the MD5 hash of the Internet + Draft). Note that by doing so, you potentially lose + interoperability with other TLS implementations since these might + be using the same extension number for other purposes. + + SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the + opaque PRF input value to use in the handshake. This will create + an interal copy of the length-'len' string at 'src', and will + return non-zero for success. + + To get more control and flexibility, provide a callback function + by using + + SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb) + SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg) + + where + + int (*cb)(SSL *, void *peerinput, size_t len, void *arg); + void *arg; + + Callback function 'cb' will be called in handshakes, and is + expected to use SSL_set_tlsext_opaque_prf_input() as appropriate. + Argument 'arg' is for application purposes (the value as given to + SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly + be provided to the callback function). The callback function + has to return non-zero to report success: usually 1 to use opaque + PRF input just if possible, or 2 to enforce use of the opaque PRF + input. In the latter case, the library will abort the handshake + if opaque PRF input is not successfully negotiated. + + Arguments 'peerinput' and 'len' given to the callback function + will always be NULL and 0 in the case of a client. A server will + see the client's opaque PRF input through these variables if + available (NULL and 0 otherwise). Note that if the server + provides an opaque PRF input, the length must be the same as the + length of the client's opaque PRF input. + + Note that the callback function will only be called when creating + a new session (session resumption can resume whatever was + previously negotiated), and will not be called in SSL 2.0 + handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or + SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended + for applications that need to enforce opaque PRF input. + + [Bodo Moeller] + + *) Update ssl code to support digests other than SHA1+MD5 for handshake + MAC. + + [Victor B. Wagner ] + + *) Add RFC4507 support to OpenSSL. This includes the corrections in + RFC4507bis. The encrypted ticket format is an encrypted encoded + SSL_SESSION structure, that way new session features are automatically + supported. + + If a client application caches session in an SSL_SESSION structure + support is transparent because tickets are now stored in the encoded + SSL_SESSION. + + The SSL_CTX structure automatically generates keys for ticket + protection in servers so again support should be possible + with no application modification. + + If a client or server wishes to disable RFC4507 support then the option + SSL_OP_NO_TICKET can be set. + + Add a TLS extension debugging callback to allow the contents of any client + or server extensions to be examined. + + This work was sponsored by Google. + [Steve Henson] + + *) Final changes to avoid use of pointer pointer casts in OpenSSL. + OpenSSL should now compile cleanly on gcc 4.2 + [Peter Hartley , Steve Henson] + + *) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC + support including streaming MAC support: this is required for GOST + ciphersuite support. + [Victor B. Wagner , Steve Henson] + + *) Add option -stream to use PKCS#7 streaming in smime utility. New + function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream() + to output in BER and PEM format. + [Steve Henson] + + *) Experimental support for use of HMAC via EVP_PKEY interface. This + allows HMAC to be handled via the EVP_DigestSign*() interface. The + EVP_PKEY "key" in this case is the HMAC key, potentially allowing + ENGINE support for HMAC keys which are unextractable. New -mac and + -macopt options to dgst utility. + [Steve Henson] + + *) New option -sigopt to dgst utility. Update dgst to use + EVP_Digest{Sign,Verify}*. These two changes make it possible to use + alternative signing paramaters such as X9.31 or PSS in the dgst + utility. + [Steve Henson] + + *) Change ssl_cipher_apply_rule(), the internal function that does + the work each time a ciphersuite string requests enabling + ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or + removing ("!foo+bar") a class of ciphersuites: Now it maintains + the order of disabled ciphersuites such that those ciphersuites + that most recently went from enabled to disabled not only stay + in order with respect to each other, but also have higher priority + than other disabled ciphersuites the next time ciphersuites are + enabled again. + + This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable + the same ciphersuites as with "HIGH" alone, but in a specific + order where the PSK ciphersuites come first (since they are the + most recently disabled ciphersuites when "HIGH" is parsed). + + Also, change ssl_create_cipher_list() (using this new + funcionality) such that between otherwise identical + cihpersuites, ephemeral ECDH is preferred over ephemeral DH in + the default order. + [Bodo Moeller] + + *) Change ssl_create_cipher_list() so that it automatically + arranges the ciphersuites in reasonable order before starting + to process the rule string. Thus, the definition for "DEFAULT" + (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but + remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH". + This makes it much easier to arrive at a reasonable default order + in applications for which anonymous ciphers are OK (meaning + that you can't actually use DEFAULT). + [Bodo Moeller; suggested by Victor Duchovni] + + *) Split the SSL/TLS algorithm mask (as used for ciphersuite string + processing) into multiple integers instead of setting + "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK", + "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer. + (These masks as well as the individual bit definitions are hidden + away into the non-exported interface ssl/ssl_locl.h, so this + change to the definition of the SSL_CIPHER structure shouldn't + affect applications.) This give us more bits for each of these + categories, so there is no longer a need to coagulate AES128 and + AES256 into a single algorithm bit, and to coagulate Camellia128 + and Camellia256 into a single algorithm bit, which has led to all + kinds of kludges. + + Thus, among other things, the kludge introduced in 0.9.7m and + 0.9.8e for masking out AES256 independently of AES128 or masking + out Camellia256 independently of AES256 is not needed here in 0.9.9. + + With the change, we also introduce new ciphersuite aliases that + so far were missing: "AES128", "AES256", "CAMELLIA128", and + "CAMELLIA256". + [Bodo Moeller] + + *) Add support for dsa-with-SHA224 and dsa-with-SHA256. + Use the leftmost N bytes of the signature input if the input is + larger than the prime q (with N being the size in bytes of q). + [Nils Larsch] + + *) Very *very* experimental PKCS#7 streaming encoder support.

Safestack is + reimplemented. Update ASN1 to avoid use of legacy functions. + [Steve Henson] + + *) Win32/64 targets are linked with Winsock2. + [Andy Polyakov] + + *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected + to external functions. This can be used to increase CRL handling + efficiency especially when CRLs are very large by (for example) storing + the CRL revoked certificates in a database. + [Steve Henson] + + *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so + new CRLs added to a directory can be used. New command line option + -verify_return_error to s_client and s_server. This causes real errors + to be returned by the verify callback instead of carrying on no matter + what. This reflects the way a "real world" verify callback would behave. + [Steve Henson] + + *) GOST engine, supporting several GOST algorithms and public key formats. + Kindly donated by Cryptocom. + [Cryptocom] + + *) Partial support for Issuing Distribution Point CRL extension. CRLs + partitioned by DP are handled but no indirect CRL or reason partitioning + (yet). Complete overhaul of CRL handling: now the most suitable CRL is + selected via a scoring technique which handles IDP and AKID in CRLs. + [Steve Henson] + + *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which + will ultimately be used for all verify operations: this will remove the + X509_STORE dependency on certificate verification and allow alternative + lookup methods. X509_STORE based implementations of these two callbacks. + [Steve Henson] + + *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names. + Modify get_crl() to find a valid (unexpired) CRL if possible. + [Steve Henson] + + *) New function X509_CRL_match() to check if two CRLs are identical. Normally + this would be called X509_CRL_cmp() but that name is already used by + a function that just compares CRL issuer names.

This change makes + the array representation useful in a more general context. + [Douglas Stebila] + + *) Various modifications and fixes to SSL/TLS cipher string + handling. For ECC, the code now distinguishes between fixed ECDH + with RSA certificates on the one hand and with ECDSA certificates + on the other hand, since these are separate ciphersuites. The + unused code for Fortezza ciphersuites has been removed. + + For consistency with EDH, ephemeral ECDH is now called "EECDH" + (not "ECDHE"). For consistency with the code for DH + certificates, use of ECDH certificates is now considered ECDH + authentication, not RSA or ECDSA authentication (the latter is + merely the CA's signing algorithm and not actively used in the + protocol). + + The temporary ciphersuite alias "ECCdraft" is no longer + available, and ECC ciphersuites are no longer excluded from "ALL" + and "DEFAULT". The following aliases now exist for RFC 4492 + ciphersuites, most of these by analogy with the DH case: + + kECDHr - ECDH cert, signed with RSA + kECDHe - ECDH cert, signed with ECDSA + kECDH - ECDH cert (signed with either RSA or ECDSA) + kEECDH - ephemeral ECDH + ECDH - ECDH cert or ephemeral ECDH + + aECDH - ECDH cert + aECDSA - ECDSA cert + ECDSA - ECDSA cert + + AECDH - anonymous ECDH + EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") + + [Bodo Moeller] + + *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. + Use correct micalg parameters depending on digest(s) in signed message. + [Steve Henson] + + *) Add engine support for EVP_PKEY_ASN1_METHOD.

This is now + supported by any public key method supporting the encrypt operation. A + ctrl is added to allow the public key algorithm to examine or modify + the PKCS#7 RecipientInfo structure if it needs to: for RSA this is + a no op. + [Steve Henson] + + *) Add a ctrl to asn1 method to allow a public key algorithm to express + a default digest type to use. In most cases this will be SHA1 but some + algorithms (such as GOST) need to specify an alternative digest. The + return value indicates how strong the prefernce is 1 means optional and + 2 is mandatory (that is it is the only supported type). Modify + ASN1_item_sign() to accept a NULL digest argument to indicate it should + use the default md. Update openssl utilities to use the default digest + type for signing if it is not explicitly indicated. + [Steve Henson] + + *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New + EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant + signing method from the key type. This effectively removes the link + between digests and public key types. + [Steve Henson] + + *) Add an OID cross reference table and utility functions. Its purpose is to + translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, + rsaEncryption. This will allow some of the algorithm specific hackery + needed to use the correct OID to be removed. + [Steve Henson] + + *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO + structures for PKCS7_sign(). They are now set up by the relevant public + key ASN1 method. + [Steve Henson] + + *) Add provisional EC pkey method with support for ECDSA and ECDH. + [Steve Henson] + + *) Add support for key derivation (agreement) in the API, DH method and + pkeyutl. + [Steve Henson] + + *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support + public and private key formats. As a side effect these add additional + command line functionality not previously available: DSA signatures can be + generated and verified using pkeyutl and DH key support and generation in + pkey, genpkey. + [Steve Henson] + + *) BeOS support. + [Oliver Tappe ] + + *) New make target "install_html_docs" installs HTML renditions of the + manual pages. + [Oliver Tappe ] + + *) New utility "genpkey" this is analagous to "genrsa" etc except it can + generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to + support key and parameter generation and add initial key generation + functionality for RSA. + [Steve Henson] + + *) Add functions for main EVP_PKEY_method operations. The undocumented + functions EVP_PKEY_{encrypt,decrypt} have been renamed to + EVP_PKEY_{encrypt,decrypt}_old. + [Steve Henson] + + *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public + key API, doesn't do much yet. + [Steve Henson] + + *) New function EVP_PKEY_asn1_get0_info() to retrieve information about + public key algorithms. New option to openssl utility: + "list-public-key-algorithms" to print out info. + [Steve Henson] + + *) Implement the Supported Elliptic Curves Extension for + ECC ciphersuites from draft-ietf-tls-ecc-12.txt. + [Douglas Stebila] + + *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or + EVP_CIPHER structures to avoid later problems in EVP_cleanup(). + [Steve Henson] + + *) New utilities pkey and pkeyparam. These are similar to algorithm specific + utilities such as rsa, dsa, dsaparam etc except they process any key + type. + [Steve Henson] + + *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New + functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), + EVP_PKEY_print_param() to print public key data from an EVP_PKEY + structure. + [Steve Henson] + + *) Initial support for pluggable public key ASN1. + De-spaghettify the public key ASN1 handling. Move public and private + key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate + algorithm specific handling to a single module within the relevant + algorithm directory. Add functions to allow (near) opaque processing + of public and private key structures. + [Steve Henson] + + *) Implement the Supported Point Formats Extension for + ECC ciphersuites from draft-ietf-tls-ecc-12.txt. + [Douglas Stebila] + + *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members + for the psk identity [hint] and the psk callback functions to the + SSL_SESSION, SSL and SSL_CTX structure. + + New ciphersuites: + PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, + PSK-AES256-CBC-SHA + + New functions: + SSL_CTX_use_psk_identity_hint + SSL_get_psk_identity_hint + SSL_get_psk_identity + SSL_use_psk_identity_hint + + [Mika Kousa and Pasi Eronen of Nokia Corporation] + + *) Add RFC 3161 compliant time stamp request creation, response generation + and response verification functionality. + [Zoltán Glózik , The OpenTSA Project] + + *) Add initial support for TLS extensions, specifically for the server_name + extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now + have new members for a host name. The SSL data structure has an + additional member SSL_CTX *initial_ctx so that new sessions can be + stored in that context to allow for session resumption, even after the + SSL has been switched to a new SSL_CTX in reaction to a client's + server_name extension. + + New functions (subject to change): + + SSL_get_servername() + SSL_get_servername_type() + SSL_set_SSL_CTX() + + New CTRL codes and macros (subject to change): + + SSL_CTRL_SET_TLSEXT_SERVERNAME_CB + - SSL_CTX_set_tlsext_servername_callback() + SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG + - SSL_CTX_set_tlsext_servername_arg() + SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() + + openssl s_client has a new '-servername ...' option. + + openssl s_server has new options '-servername_host ...', '-cert2 ...', + '-key2 ...', '-servername_fatal' (subject to change). This allows + testing the HostName extension for a specific single host name ('-cert' + and '-key' remain fallbacks for handshakes without HostName + negotiation). If the unrecogninzed_name alert has to be sent, this by + default is a warning; it becomes fatal with the '-servername_fatal' + option. + + [Peter Sylvester, Remy Allais, Christophe Renou] + + *) Whirlpool hash implementation is added. + [Andy Polyakov] + + *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to + bn(64,32). Because of instruction set limitations it doesn't have + any negative impact on performance. This was done mostly in order + to make it possible to share assembler modules, such as bn_mul_mont + implementations, between 32- and 64-bit builds without hassle. + [Andy Polyakov] + + *) Move code previously exiled into file crypto/ec/ec2_smpt.c + to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP + macro. + [Bodo Moeller] + + *) New candidate for BIGNUM assembler implementation, bn_mul_mont, + dedicated Montgomery multiplication procedure, is introduced. + BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher + "64-bit" performance on certain 32-bit targets. + [Andy Polyakov] + + *) New option SSL_OP_NO_COMP to disable use of compression selectively + in SSL structures. New SSL ctrl to set maximum send fragment size. + Save memory by seeting the I/O buffer sizes dynamically instead of + using the maximum available value. + [Steve Henson] + + *) New option -V for 'openssl ciphers'. This prints the ciphersuite code + in addition to the text details. + [Bodo Moeller] + + *) Very, very preliminary EXPERIMENTAL support for printing of general + ASN1 structures. This currently produces rather ugly output and doesn't + handle several customised structures at all. + [Steve Henson] + + *) Integrated support for PVK file format and some related formats such + as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support + these in the 'rsa' and 'dsa' utilities. + [Steve Henson] + + *) Support for PKCS#1 RSAPublicKey format on rsa utility command line. + [Steve Henson] + + *) Remove the ancient ASN1_METHOD code. This was only ever used in one + place for the (very old) "NETSCAPE" format certificates which are now + handled using new ASN1 code equivalents. + [Steve Henson] + + *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD + pointer and make the SSL_METHOD parameter in SSL_CTX_new, + SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'. + [Nils Larsch] + + *) Modify CRL distribution points extension code to print out previously + unsupported fields. Enhance extension setting code to allow setting of + all fields. + [Steve Henson] + + *) Add print and set support for Issuing Distribution Point CRL extension. + [Steve Henson] + + *) Change 'Configure' script to enable Camellia by default. + [NTT] + + Changes between 0.9.8m and 0.9.8n [24 Mar 2010] + + *) When rejecting SSL/TLS records due to an incorrect version number, never + update s->server with a new major version number.

So instead simplify the code to flush unconditionally. + This should be fine since flushing with no data to flush is a no op. + [Steve Henson] + + *) Handle TLS versions 2.0 and later properly and correctly use the + highest version of TLS/SSL supported. Although TLS >= 2.0 is some way + off ancient servers have a habit of sticking around for a while... + [Steve Henson] + + *) Modify compression code so it frees up structures without using the + ex_data callbacks. This works around a problem where some applications + call CRYPTO_cleanup_all_ex_data() before application exit (e.g. when + restarting) then use compression (e.g. SSL with compression) later. + This results in significant per-connection memory leaks and + has caused some security issues including CVE-2008-1678 and + CVE-2009-4355. + [Steve Henson] + + *) Constify crypto/cast (i.e., ): a CAST_KEY doesn't + change when encrypting or decrypting. + [Bodo Moeller] + + *) Add option SSL_OP_LEGACY_SERVER_CONNECT which will allow clients to + connect and renegotiate with servers which do not support RI. + Until RI is more widely deployed this option is enabled by default. + [Steve Henson] + + *) Add "missing" ssl ctrls to clear options and mode. + [Steve Henson] + + *) If client attempts to renegotiate and doesn't support RI respond with + a no_renegotiation alert as required by RFC5746. Some renegotiating + TLS clients will continue a connection gracefully when they receive + the alert. Unfortunately OpenSSL mishandled this alert and would hang + waiting for a server hello which it will never receive. Now we treat a + received no_renegotiation alert as a fatal error. This is because + applications requesting a renegotiation might well expect it to succeed + and would have no code in place to handle the server denying it so the + only safe thing to do is to terminate the connection. + [Steve Henson] + + *) Add ctrl macro SSL_get_secure_renegotiation_support() which returns 1 if + peer supports secure renegotiation and 0 otherwise.

For detailed background information, see + http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron, + J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL + and Necessary Software Countermeasures"). The core of the change + are new versions BN_div_no_branch() and + BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(), + respectively, which are slower, but avoid the security-relevant + conditional branches. These are automatically called by BN_div() + and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one + of the input BIGNUMs. Also, BN_is_bit_set() has been changed to + remove a conditional branch. + + BN_FLG_CONSTTIME is the new name for the previous + BN_FLG_EXP_CONSTTIME flag, since it now affects more than just + modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag + in the exponent causes BN_mod_exp_mont() to use the alternative + implementation in BN_mod_exp_mont_consttime().) The old name + remains as a deprecated alias. + + Similary, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general + RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses + constant-time implementations for more than just exponentiation. + Here too the old name is kept as a deprecated alias. + + BN_BLINDING_new() will now use BN_dup() for the modulus so that + the BN_BLINDING structure gets an independent copy of the + modulus. This means that the previous "BIGNUM *m" argument to + BN_BLINDING_new() and to BN_BLINDING_create_param() now + essentially becomes "const BIGNUM *m", although we can't actually + change this in the header file before 0.9.9.

Some "openssl" subcommands and a few of + the self-tests were still using deprecated key-generation functions so + these have been updated also. + [Geoff Thorpe] + + *) Reorganise PKCS#7 code to separate the digest location functionality + into PKCS7_find_digest(), digest addtion into PKCS7_bio_add_digest(). + New function PKCS7_set_digest() to set the digest type for PKCS#7 + digestedData type. Add additional code to correctly generate the + digestedData type and add support for this type in PKCS7 initialization + functions. + [Steve Henson] + + *) New function PKCS7_set0_type_other() this initializes a PKCS7 + structure of type "other". + [Steve Henson] + + *) Fix prime generation loop in crypto/bn/bn_prime.pl by making + sure the loop does correctly stop and breaking ("division by zero") + modulus operations are not performed. The (pre-generated) prime + table crypto/bn/bn_prime.h was already correct, but it could not be + re-generated on some platforms because of the "division by zero" + situation in the script. + [Ralf S. Engelschall] + + *) Update support for ECC-based TLS ciphersuites according to + draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with + SHA-1 now is only used for "small" curves (where the + representation of a field element takes up to 24 bytes); for + larger curves, the field element resulting from ECDH is directly + used as premaster secret. + [Douglas Stebila (Sun Microsystems Laboratories)] + + *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2 + curve secp160r1 to the tests. + [Douglas Stebila (Sun Microsystems Laboratories)] + + *) Add the possibility to load symbols globally with DSO. + [Götz Babin-Ebell via Richard Levitte] + + *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better + control of the error stack. + [Richard Levitte] + + *) Add support for STORE in ENGINE. + [Richard Levitte] + + *) Add the STORE type. The intention is to provide a common interface + to certificate and key stores, be they simple file-based stores, or + HSM-type store, or LDAP stores, or... + NOTE: The code is currently UNTESTED and isn't really used anywhere. + [Richard Levitte] + + *) Add a generic structure called OPENSSL_ITEM. This can be used to + pass a list of arguments to any function as well as provide a way + for a function to pass data back to the caller. + [Richard Levitte] + + *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup() + works like BUF_strdup() but can be used to duplicate a portion of + a string. The copy gets NUL-terminated. BUF_memdup() duplicates + a memory area. + [Richard Levitte] + + *) Add the function sk_find_ex() which works like sk_find(), but will + return an index to an element even if an exact match couldn't be + found. The index is guaranteed to point at the element where the + searched-for key would be inserted to preserve sorting order. + [Richard Levitte] + + *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but + takes an extra flags argument for optional functionality. Currently, + the following flags are defined: + + OBJ_BSEARCH_VALUE_ON_NOMATCH + This one gets OBJ_bsearch_ex() to return a pointer to the first + element where the comparing function returns a negative or zero + number. + + OBJ_BSEARCH_FIRST_VALUE_ON_MATCH + This one gets OBJ_bsearch_ex() to return a pointer to the first + element where the comparing function returns zero. This is useful + if there are more than one element where the comparing function + returns zero. + [Richard Levitte] + + *) Make it possible to create self-signed certificates with 'openssl ca' + in such a way that the self-signed certificate becomes part of the + CA database and uses the same mechanisms for serial number generation + as all other certificate signing. The new flag '-selfsign' enables + this functionality. Adapt CA.sh and CA.pl.in. + [Richard Levitte] + + *) Add functionality to check the public key of a certificate request + against a given private. This is useful to check that a certificate + request can be signed by that key (self-signing). + [Richard Levitte] + + *) Make it possible to have multiple active certificates with the same + subject in the CA index file. This is done only if the keyword + 'unique_subject' is set to 'no' in the main CA section (default + if 'CA_default') of the configuration file. The value is saved + with the database itself in a separate index attribute file, + named like the index file with '.attr' appended to the name. + [Richard Levitte] + + *) Generate muti valued AVAs using '+' notation in config files for + req and dirName. + [Steve Henson] + + *) Support for nameConstraints certificate extension. + [Steve Henson] + + *) Support for policyConstraints certificate extension. + [Steve Henson] + + *) Support for policyMappings certificate extension. + [Steve Henson] + + *) Make sure the default DSA_METHOD implementation only uses its + dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL, + and change its own handlers to be NULL so as to remove unnecessary + indirection. This lets alternative implementations fallback to the + default implementation more easily. + [Geoff Thorpe] + + *) Support for directoryName in GeneralName related extensions + in config files. + [Steve Henson] + + *) Make it possible to link applications using Makefile.shared. + Make that possible even when linking against static libraries! + [Richard Levitte] + + *) Support for single pass processing for S/MIME signing. This now + means that S/MIME signing can be done from a pipe, in addition + cleartext signing (multipart/signed type) is effectively streaming + and the signed data does not need to be all held in memory. + + This is done with a new flag PKCS7_STREAM. When this flag is set + PKCS7_sign() only initializes the PKCS7 structure and the actual signing + is done after the data is output (and digests calculated) in + SMIME_write_PKCS7(). + [Steve Henson] + + *) Add full support for -rpath/-R, both in shared libraries and + applications, at least on the platforms where it's known how + to do it. + [Richard Levitte] + + *) In crypto/ec/ec_mult.c, implement fast point multiplication with + precomputation, based on wNAF splitting: EC_GROUP_precompute_mult() + will now compute a table of multiples of the generator that + makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul() + faster (notably in the case of a single point multiplication, + scalar * generator). + [Nils Larsch, Bodo Moeller] + + *) IPv6 support for certificate extensions. The various extensions + which use the IP:a.b.c.d can now take IPv6 addresses using the + formats of RFC1884 2.2 . IPv6 addresses are now also displayed + correctly. + [Steve Henson] + + *) Added an ENGINE that implements RSA by performing private key + exponentiations with the GMP library. The conversions to and from + GMP's mpz_t format aren't optimised nor are any montgomery forms + cached, and on x86 it appears OpenSSL's own performance has caught up. + However there are likely to be other architectures where GMP could + provide a boost. This ENGINE is not built in by default, but it can be + specified at Configure time and should be accompanied by the necessary + linker additions, eg; + ./config -DOPENSSL_USE_GMP -lgmp + [Geoff Thorpe] + + *) "openssl engine" will not display ENGINE/DSO load failure errors when + testing availability of engines with "-t" - the old behaviour is + produced by increasing the feature's verbosity with "-tt". + [Geoff Thorpe] + + *) ECDSA routines: under certain error conditions uninitialized BN objects + could be freed. Solution: make sure initialization is performed early + enough. (Reported and fix supplied by Nils Larsch + via PR#459) + [Lutz Jaenicke] + + *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD + and DH_METHOD (eg. by ENGINE implementations) to override the normal + software implementations. For DSA and DH, parameter generation can + also be overriden by providing the appropriate method callbacks. + [Geoff Thorpe] + + *) Change the "progress" mechanism used in key-generation and + primality testing to functions that take a new BN_GENCB pointer in + place of callback/argument pairs. The new API functions have "_ex" + postfixes and the older functions are reimplemented as wrappers for + the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide + declarations of the old functions to help (graceful) attempts to + migrate to the new functions. Also, the new key-generation API + functions operate on a caller-supplied key-structure and return + success/failure rather than returning a key or NULL - this is to + help make "keygen" another member function of RSA_METHOD etc. + + Example for using the new callback interface: + + int (*my_callback)(int a, int b, BN_GENCB *cb) = ...; + void *my_arg = ...; + BN_GENCB my_cb; + + BN_GENCB_set(&my_cb, my_callback, my_arg); + + return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb); + /* For the meaning of a, b in calls to my_callback(), see the + * documentation of the function that calls the callback. + * cb will point to my_cb; my_arg can be retrieved as cb->arg. + * my_callback should return 1 if it wants BN_is_prime_ex() + * to continue, or 0 to stop. + */ + + [Geoff Thorpe] + + *) Change the ZLIB compression method to be stateful, and make it + available to TLS with the number defined in + draft-ietf-tls-compression-04.txt. + [Richard Levitte] + + *) Add the ASN.1 structures and functions for CertificatePair, which + is defined as follows (according to X.509_4thEditionDraftV6.pdf): + + CertificatePair ::= SEQUENCE { + forward [0] Certificate OPTIONAL, + reverse [1] Certificate OPTIONAL, + -- at least one of the pair shall be present -- } + + Also implement the PEM functions to read and write certificate + pairs, and defined the PEM tag as "CERTIFICATE PAIR". + + This needed to be defined, mostly for the sake of the LDAP + attribute crossCertificatePair, but may prove useful elsewhere as + well. + [Richard Levitte] + + *) Make it possible to inhibit symlinking of shared libraries in + Makefile.shared, for Cygwin's sake. + [Richard Levitte] + + *) Extend the BIGNUM API by creating a function + void BN_set_negative(BIGNUM *a, int neg); + and a macro that behave like + int BN_is_negative(const BIGNUM *a); + + to avoid the need to access 'a->neg' directly in applications. + [Nils Larsch] + + *) Implement fast modular reduction for pseudo-Mersenne primes + used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c). + EC_GROUP_new_curve_GFp() will now automatically use this + if applicable. + [Nils Larsch ] + + *) Add new lock type (CRYPTO_LOCK_BN). + [Bodo Moeller] + + *) Change the ENGINE framework to automatically load engines + dynamically from specific directories unless they could be + found to already be built in or loaded. Move all the + current engines except for the cryptodev one to a new + directory engines/. + The engines in engines/ are built as shared libraries if + the "shared" options was given to ./Configure or ./config. + Otherwise, they are inserted in libcrypto.a. + /usr/local/ssl/engines is the default directory for dynamic + engines, but that can be overriden at configure time through + the usual use of --prefix and/or --openssldir, and at run + time with the environment variable OPENSSL_ENGINES. + [Geoff Thorpe and Richard Levitte] + + *) Add Makefile.shared, a helper makefile to build shared + libraries. Addapt Makefile.org. + [Richard Levitte] + + *) Add version info to Win32 DLLs. + [Peter 'Luna' Runestig" ] + + *) Add new 'medium level' PKCS#12 API. Certificates and keys + can be added using this API to created arbitrary PKCS#12 + files while avoiding the low level API. + + New options to PKCS12_create(), key or cert can be NULL and + will then be omitted from the output file. The encryption + algorithm NIDs can be set to -1 for no encryption, the mac + iteration count can be set to 0 to omit the mac. + + Enhance pkcs12 utility by making the -nokeys and -nocerts + options work when creating a PKCS#12 file. New option -nomac + to omit the mac, NONE can be set for an encryption algorithm. + New code is modified to use the enhanced PKCS12_create() + instead of the low level API. + [Steve Henson] + + *) Extend ASN1 encoder to support indefinite length constructed + encoding. This can output sequences tags and octet strings in + this form. Modify pk7_asn1.c to support indefinite length + encoding. This is experimental and needs additional code to + be useful, such as an ASN1 bio and some enhanced streaming + PKCS#7 code. + + Extend template encode functionality so that tagging is passed + down to the template encoder. + [Steve Henson] + + *) Let 'openssl req' fail if an argument to '-newkey' is not + recognized instead of using RSA as a default. + [Bodo Moeller] + + *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt. + As these are not official, they are not included in "ALL"; + the "ECCdraft" ciphersuite group alias can be used to select them. + [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)] + + *) Add ECDH engine support. + [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)] + + *) Add ECDH in new directory crypto/ecdh/. + [Douglas Stebila (Sun Microsystems Laboratories)] + + *) Let BN_rand_range() abort with an error after 100 iterations + without success (which indicates a broken PRNG). + [Bodo Moeller] + + *) Change BN_mod_sqrt() so that it verifies that the input value + is really the square of the return value.

Make RSA blinding thread-safe + by remembering the creator's thread ID in rsa->blinding and + having all other threads use local one-time blinding factors + (this requires more computation than sharing rsa->blinding, but + avoids excessive locking; and if an RSA object is not shared + between threads, blinding will still be very fast). + [Bodo Moeller] + + *) Fixed a typo bug that would cause ENGINE_set_default() to set an + ENGINE as defaults for all supported algorithms irrespective of + the 'flags' parameter.

Some + time in the future, des_old.h and the libdes compatibility functions + will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the + default), and then completely removed. + [Richard Levitte] + + *) Test for certificates which contain unsupported critical extensions. + If such a certificate is found during a verify operation it is + rejected by default: this behaviour can be overridden by either + handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or + by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function + X509_supported_extension() has also been added which returns 1 if a + particular extension is supported. + [Steve Henson] + + *) Modify the behaviour of EVP cipher functions in similar way to digests + to retain compatibility with existing code. + [Steve Henson] + + *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain + compatibility with existing code. In particular the 'ctx' parameter does + not have to be to be initialized before the call to EVP_DigestInit() and + it is tidied up after a call to EVP_DigestFinal(). New function + EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function + EVP_MD_CTX_copy() changed to not require the destination to be + initialized valid and new function EVP_MD_CTX_copy_ex() added which + requires the destination to be valid. + + Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(), + EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex(). + [Steve Henson] + + *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it + so that complete 'Handshake' protocol structures are kept in memory + instead of overwriting 'msg_type' and 'length' with 'body' data. + [Bodo Moeller] + + *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32. + [Massimo Santin via Richard Levitte] + + *) Major restructuring to the underlying ENGINE code. This includes + reduction of linker bloat, separation of pure "ENGINE" manipulation + (initialisation, etc) from functionality dealing with implementations + of specific crypto iterfaces. This change also introduces integrated + support for symmetric ciphers and digest implementations - so ENGINEs + can now accelerate these by providing EVP_CIPHER and EVP_MD + implementations of their own. This is detailed in crypto/engine/README + as it couldn't be adequately described here. However, there are a few + API changes worth noting - some RSA, DSA, DH, and RAND functions that + were changed in the original introduction of ENGINE code have now + reverted back - the hooking from this code to ENGINE is now a good + deal more passive and at run-time, operations deal directly with + RSA_METHODs, DSA_METHODs (etc) as they did before, rather than + dereferencing through an ENGINE pointer any more. Also, the ENGINE + functions dealing with BN_MOD_EXP[_CRT] handlers have been removed - + they were not being used by the framework as there is no concept of a + BIGNUM_METHOD and they could not be generalised to the new + 'ENGINE_TABLE' mechanism that underlies the new code. Similarly, + ENGINE_cpy() has been removed as it cannot be consistently defined in + the new code. + [Geoff Thorpe] + + *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds. + [Steve Henson] + + *) Change mkdef.pl to sort symbols that get the same entry number, + and make sure the automatically generated functions ERR_load_* + become part of libeay.num as well. + [Richard Levitte] + + *) New function SSL_renegotiate_pending(). This returns true once + renegotiation has been requested (either SSL_renegotiate() call + or HelloRequest/ClientHello receveived from the peer) and becomes + false once a handshake has been completed. + (For servers, SSL_renegotiate() followed by SSL_do_handshake() + sends a HelloRequest, but does not ensure that a handshake takes + place. SSL_renegotiate_pending() is useful for checking if the + client has followed the request.) + [Bodo Moeller] + + *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION. + By default, clients may request session resumption even during + renegotiation (if session ID contexts permit); with this option, + session resumption is possible only in the first handshake. + + SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes + more bits available for options that should not be part of + SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION). + [Bodo Moeller] + + *) Add some demos for certificate and certificate request creation. + [Steve Henson] + + *) Make maximum certificate chain size accepted from the peer application + settable (SSL*_get/set_max_cert_list()), as proposed by + "Douglas E. Engert" . + [Lutz Jaenicke] + + *) Add support for shared libraries for Unixware-7 + (Boyd Lynn Gerber ). + [Lutz Jaenicke] + + *) Add a "destroy" handler to ENGINEs that allows structural cleanup to + be done prior to destruction. Use this to unload error strings from + ENGINEs that load their own error strings. NB: This adds two new API + functions to "get" and "set" this destroy handler in an ENGINE. + [Geoff Thorpe] + + *) Alter all existing ENGINE implementations (except "openssl" and + "openbsd") to dynamically instantiate their own error strings. This + makes them more flexible to be built both as statically-linked ENGINEs + and self-contained shared-libraries loadable via the "dynamic" ENGINE. + Also, add stub code to each that makes building them as self-contained + shared-libraries easier (see README.ENGINE). + [Geoff Thorpe] + + *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE + implementations into applications that are completely implemented in + self-contained shared-libraries. The "dynamic" ENGINE exposes control + commands that can be used to configure what shared-library to load and + to control aspects of the way it is handled. Also, made an update to + the README.ENGINE file that brings its information up-to-date and + provides some information and instructions on the "dynamic" ENGINE + (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc). + [Geoff Thorpe] + + *) Make it possible to unload ranges of ERR strings with a new + "ERR_unload_strings" function. + [Geoff Thorpe] + + *) Add a copy() function to EVP_MD. + [Ben Laurie] + + *) Make EVP_MD routines take a context pointer instead of just the + md_data void pointer. + [Ben Laurie] + + *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates + that the digest can only process a single chunk of data + (typically because it is provided by a piece of + hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application + is only going to provide a single chunk of data, and hence the + framework needn't accumulate the data for oneshot drivers. + [Ben Laurie] + + *) As with "ERR", make it possible to replace the underlying "ex_data" + functions. This change also alters the storage and management of global + ex_data state - it's now all inside ex_data.c and all "class" code (eg. + RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class + index counters. The API functions that use this state have been changed + to take a "class_index" rather than pointers to the class's local STACK + and counter, and there is now an API function to dynamically create new + classes. This centralisation allows us to (a) plug a lot of the + thread-safety problems that existed, and (b) makes it possible to clean + up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b) + such data would previously have always leaked in application code and + workarounds were in place to make the memory debugging turn a blind eye + to it. Application code that doesn't use this new function will still + leak as before, but their memory debugging output will announce it now + rather than letting it slide. + + Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change + induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now + has a return value to indicate success or failure. + [Geoff Thorpe] + + *) Make it possible to replace the underlying "ERR" functions such that the + global state (2 LHASH tables and 2 locks) is only used by the "default" + implementation. This change also adds two functions to "get" and "set" + the implementation prior to it being automatically set the first time + any other ERR function takes place. Ie. an application can call "get", + pass the return value to a module it has just loaded, and that module + can call its own "set" function using that value. This means the + module's "ERR" operations will use (and modify) the error state in the + application and not in its own statically linked copy of OpenSSL code. + [Geoff Thorpe] + + *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment + reference counts. This performs normal REF_PRINT/REF_CHECK macros on + the operation, and provides a more encapsulated way for external code + (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code + to use these functions rather than manually incrementing the counts. + + Also rename "DSO_up()" function to more descriptive "DSO_up_ref()". + [Geoff Thorpe] + + *) Add EVP test program. + [Ben Laurie] + + *) Add symmetric cipher support to ENGINE. Expect the API to change! + [Ben Laurie] + + *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name() + X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(), + X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate(). + These allow a CRL to be built without having to access X509_CRL fields + directly. Modify 'ca' application to use new functions. + [Steve Henson] + + *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended + bug workarounds. Rollback attack detection is a security feature. + The problem will only arise on OpenSSL servers when TLSv1 is not + available (sslv3_server_method() or SSL_OP_NO_TLSv1). + Software authors not wanting to support TLSv1 will have special reasons + for their choice and can explicitly enable this option. + [Bodo Moeller, Lutz Jaenicke] + + *) Rationalise EVP so it can be extended: don't include a union of + cipher/digest structures, add init/cleanup functions for EVP_MD_CTX + (similar to those existing for EVP_CIPHER_CTX). + Usage example: + + EVP_MD_CTX md; + + EVP_MD_CTX_init(&md); /* new function call */ + EVP_DigestInit(&md, EVP_sha1()); + EVP_DigestUpdate(&md, in, len); + EVP_DigestFinal(&md, out, NULL); + EVP_MD_CTX_cleanup(&md); /* new function call */ + + [Ben Laurie] + + *) Make DES key schedule conform to the usual scheme, as well as + correcting its structure. This means that calls to DES functions + now have to pass a pointer to a des_key_schedule instead of a + plain des_key_schedule (which was actually always a pointer + anyway): E.g., + + des_key_schedule ks; + + des_set_key_checked(..., &ks); + des_ncbc_encrypt(..., &ks, ...); + + (Note that a later change renames 'des_...' into 'DES_...'.) + [Ben Laurie] + + *) Initial reduction of linker bloat: the use of some functions, such as + PEM causes large amounts of unused functions to be linked in due to + poor organisation. For example pem_all.c contains every PEM function + which has a knock on effect of linking in large amounts of (unused) + ASN1 code. Grouping together similar functions and splitting unrelated + functions prevents this. + [Steve Henson] + + *) Cleanup of EVP macros. + [Ben Laurie] + + *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the + correct _ecb suffix. + [Ben Laurie] + + *) Add initial OCSP responder support to ocsp application. The + revocation information is handled using the text based index + use by the ca application. The responder can either handle + requests generated internally, supplied in files (for example + via a CGI script) or using an internal minimal server. + [Steve Henson] + + *) Add configuration choices to get zlib compression for TLS. + [Richard Levitte] + + *) Changes to Kerberos SSL for RFC 2712 compliance: + 1. Implemented real KerberosWrapper, instead of just using + KRB5 AP_REQ message. [Thanks to Simon Wilkinson ] + 2. Implemented optional authenticator field of KerberosWrapper. + + Added openssl-style ASN.1 macros for Kerberos ticket, ap_req, + and authenticator structs; see crypto/krb5/. + + Generalized Kerberos calls to support multiple Kerberos libraries. + [Vern Staats , + Jeffrey Altman + via Richard Levitte] + + *) Cause 'openssl speed' to use fully hard-coded DSA keys as it + already does with RSA. testdsa.h now has 'priv_key/pub_key' + values for each of the key sizes rather than having just + parameters (and 'speed' generating keys each time). + [Geoff Thorpe] + + *) Speed up EVP routines. + Before: +encrypt +type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes +des-cbc 4408.85k 5560.51k 5778.46k 5862.20k 5825.16k +des-cbc 4389.55k 5571.17k 5792.23k 5846.91k 5832.11k +des-cbc 4394.32k 5575.92k 5807.44k 5848.37k 5841.30k +decrypt +des-cbc 3482.66k 5069.49k 5496.39k 5614.16k 5639.28k +des-cbc 3480.74k 5068.76k 5510.34k 5609.87k 5635.52k +des-cbc 3483.72k 5067.62k 5504.60k 5708.01k 5724.80k + After: +encrypt +des-cbc 4660.16k 5650.19k 5807.19k 5827.13k 5783.32k +decrypt +des-cbc 3624.96k 5258.21k 5530.91k 5624.30k 5628.26k + [Ben Laurie] + + *) Added the OS2-EMX target. + ["Brian Havard" and Richard Levitte] + + *) Rewrite apps to use NCONF routines instead of the old CONF. New functions + to support NCONF routines in extension code. New function CONF_set_nconf() + to allow functions which take an NCONF to also handle the old LHASH + structure: this means that the old CONF compatible routines can be + retained (in particular wrt extensions) without having to duplicate the + code. New function X509V3_add_ext_nconf_sk to add extensions to a stack. + [Steve Henson] + + *) Enhance the general user interface with mechanisms for inner control + and with possibilities to have yes/no kind of prompts. + [Richard Levitte] + + *) Change all calls to low level digest routines in the library and + applications to use EVP. Add missing calls to HMAC_cleanup() and + don't assume HMAC_CTX can be copied using memcpy(). + [Verdon Walker , Steve Henson] + + *) Add the possibility to control engines through control names but with + arbitrary arguments instead of just a string. + Change the key loaders to take a UI_METHOD instead of a callback + function pointer. NOTE: this breaks binary compatibility with earlier + versions of OpenSSL [engine]. + Adapt the nCipher code for these new conditions and add a card insertion + callback. + [Richard Levitte] + + *) Enhance the general user interface with mechanisms to better support + dialog box interfaces, application-defined prompts, the possibility + to use defaults (for example default passwords from somewhere else) + and interrupts/cancellations. + [Richard Levitte] + + *) Tidy up PKCS#12 attribute handling. Add support for the CSP name + attribute in PKCS#12 files, add new -CSP option to pkcs12 utility. + [Steve Henson] + + *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also + tidy up some unnecessarily weird code in 'sk_new()'). + [Geoff, reported by Diego Tartara ] + + *) Change the key loading routines for ENGINEs to use the same kind + callback (pem_password_cb) as all other routines that need this + kind of callback. + [Richard Levitte] + + *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with + 256 bit (=32 byte) keys. Of course seeding with more entropy bytes + than this minimum value is recommended. + [Lutz Jaenicke] + + *) New random seeder for OpenVMS, using the system process statistics + that are easily reachable. + [Richard Levitte] + + *) Windows apparently can't transparently handle global + variables defined in DLLs. Initialisations such as: + + const ASN1_ITEM *it = &ASN1_INTEGER_it; + + wont compile. This is used by the any applications that need to + declare their own ASN1 modules. This was fixed by adding the option + EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly + needed for static libraries under Win32. + [Steve Henson] + + *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle + setting of purpose and trust fields. New X509_STORE trust and + purpose functions and tidy up setting in other SSL functions. + [Steve Henson] + + *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE + structure. These are inherited by X509_STORE_CTX when it is + initialised. This allows various defaults to be set in the + X509_STORE structure (such as flags for CRL checking and custom + purpose or trust settings) for functions which only use X509_STORE_CTX + internally such as S/MIME. + + Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and + trust settings if they are not set in X509_STORE. This allows X509_STORE + purposes and trust (in S/MIME for example) to override any set by default. + + Add command line options for CRL checking to smime, s_client and s_server + applications. + [Steve Henson] + + *) Initial CRL based revocation checking. If the CRL checking flag(s) + are set then the CRL is looked up in the X509_STORE structure and + its validity and signature checked, then if the certificate is found + in the CRL the verify fails with a revoked error. + + Various new CRL related callbacks added to X509_STORE_CTX structure. + + Command line options added to 'verify' application to support this. + + This needs some additional work, such as being able to handle multiple + CRLs with different times, extension based lookup (rather than just + by subject name) and ultimately more complete V2 CRL extension + handling. + [Steve Henson] + + *) Add a general user interface API (crypto/ui/). This is designed + to replace things like des_read_password and friends (backward + compatibility functions using this new API are provided). + The purpose is to remove prompting functions from the DES code + section as well as provide for prompting through dialog boxes in + a window system and the like. + [Richard Levitte] + + *) Add "ex_data" support to ENGINE so implementations can add state at a + per-structure level rather than having to store it globally. + [Geoff] + + *) Make it possible for ENGINE structures to be copied when retrieved by + ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY. + This causes the "original" ENGINE structure to act like a template, + analogous to the RSA vs. RSA_METHOD type of separation. Because of this + operational state can be localised to each ENGINE structure, despite the + fact they all share the same "methods". New ENGINE structures returned in + this case have no functional references and the return value is the single + structural reference. This matches the single structural reference returned + by ENGINE_by_id() normally, when it is incremented on the pre-existing + ENGINE structure. + [Geoff] + + *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this + needs to match any other type at all we need to manually clear the + tag cache. + [Steve Henson] + + *) Changes to the "openssl engine" utility to include; + - verbosity levels ('-v', '-vv', and '-vvv') that provide information + about an ENGINE's available control commands. + - executing control commands from command line arguments using the + '-pre' and '-post' switches. '-post' is only used if '-t' is + specified and the ENGINE is successfully initialised. The syntax for + the individual commands are colon-separated, for example; + openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so + [Geoff] + + *) New dynamic control command support for ENGINEs. ENGINEs can now + declare their own commands (numbers), names (strings), descriptions, + and input types for run-time discovery by calling applications. A + subset of these commands are implicitly classed as "executable" + depending on their input type, and only these can be invoked through + the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this + can be based on user input, config files, etc). The distinction is + that "executable" commands cannot return anything other than a boolean + result and can only support numeric or string input, whereas some + discoverable commands may only be for direct use through + ENGINE_ctrl(), eg. supporting the exchange of binary data, function + pointers, or other custom uses. The "executable" commands are to + support parameterisations of ENGINE behaviour that can be + unambiguously defined by ENGINEs and used consistently across any + OpenSSL-based application. Commands have been added to all the + existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow + control over shared-library paths without source code alterations. + [Geoff] + + *) Changed all ENGINE implementations to dynamically allocate their + ENGINEs rather than declaring them statically. Apart from this being + necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction, + this also allows the implementations to compile without using the + internal engine_int.h header. + [Geoff] + + *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a + 'const' value. Any code that should be able to modify a RAND_METHOD + should already have non-const pointers to it (ie. they should only + modify their own ones). + [Geoff] + + *) Made a variety of little tweaks to the ENGINE code. + - "atalla" and "ubsec" string definitions were moved from header files + to C code. "nuron" string definitions were placed in variables + rather than hard-coded - allowing parameterisation of these values + later on via ctrl() commands. + - Removed unused "#if 0"'d code. + - Fixed engine list iteration code so it uses ENGINE_free() to release + structural references. + - Constified the RAND_METHOD element of ENGINE structures. + - Constified various get/set functions as appropriate and added + missing functions (including a catch-all ENGINE_cpy that duplicates + all ENGINE values onto a new ENGINE except reference counts/state). + - Removed NULL parameter checks in get/set functions. Setting a method + or function to NULL is a way of cancelling out a previously set + value. Passing a NULL ENGINE parameter is just plain stupid anyway + and doesn't justify the extra error symbols and code. + - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for + flags from engine_int.h to engine.h. + - Changed prototypes for ENGINE handler functions (init(), finish(), + ctrl(), key-load functions, etc) to take an (ENGINE*) parameter. + [Geoff] + + *) Implement binary inversion algorithm for BN_mod_inverse in addition + to the algorithm using long division. The binary algorithm can be + used only if the modulus is odd. On 32-bit systems, it is faster + only for relatively small moduli (roughly 20-30% for 128-bit moduli, + roughly 5-15% for 256-bit moduli), so we use it only for moduli + up to 450 bits. In 64-bit environments, the binary algorithm + appears to be advantageous for much longer moduli; here we use it + for moduli up to 2048 bits. + [Bodo Moeller] + + *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code + could not support the combine flag in choice fields. + [Steve Henson] + + *) Add a 'copy_extensions' option to the 'ca' utility. This copies + extensions from a certificate request to the certificate. + [Steve Henson] + + *) Allow multiple 'certopt' and 'nameopt' options to be separated + by commas. Add 'namopt' and 'certopt' options to the 'ca' config + file: this allows the display of the certificate about to be + signed to be customised, to allow certain fields to be included + or excluded and extension details. The old system didn't display + multicharacter strings properly, omitted fields not in the policy + and couldn't display additional details such as extensions. + [Steve Henson] + + *) Function EC_POINTs_mul for multiple scalar multiplication + of an arbitrary number of elliptic curve points + \sum scalars[i]*points[i], + optionally including the generator defined for the EC_GROUP: + scalar*generator + \sum scalars[i]*points[i]. + + EC_POINT_mul is a simple wrapper function for the typical case + that the point list has just one item (besides the optional + generator). + [Bodo Moeller] + + *) First EC_METHODs for curves over GF(p): + + EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr + operations and provides various method functions that can also + operate with faster implementations of modular arithmetic. + + EC_GFp_mont_method() reuses most functions that are part of + EC_GFp_simple_method, but uses Montgomery arithmetic. + + [Bodo Moeller; point addition and point doubling + implementation directly derived from source code provided by + Lenka Fibikova ] + + *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h, + crypto/ec/ec_lib.c): + + Curves are EC_GROUP objects (with an optional group generator) + based on EC_METHODs that are built into the library. + + Points are EC_POINT objects based on EC_GROUP objects. + + Most of the framework would be able to handle curves over arbitrary + finite fields, but as there are no obvious types for fields other + than GF(p), some functions are limited to that for now. + [Bodo Moeller] + + *) Add the -HTTP option to s_server. It is similar to -WWW, but requires + that the file contains a complete HTTP response. + [Richard Levitte] + + *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl + change the def and num file printf format specifier from "%-40sXXX" + to "%-39s XXX". The latter will always guarantee a space after the + field while the former will cause them to run together if the field + is 40 of more characters long. + [Steve Henson] + + *) Constify the cipher and digest 'method' functions and structures + and modify related functions to take constant EVP_MD and EVP_CIPHER + pointers. + [Steve Henson] + + *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them + in . Also further increase BN_CTX_NUM to 32. + [Bodo Moeller] + + *) Modify EVP_Digest*() routines so they now return values. Although the + internal software routines can never fail additional hardware versions + might. + [Steve Henson] + + *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: + + Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 + (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. + + ASN1 error codes + ERR_R_NESTED_ASN1_ERROR + ... + ERR_R_MISSING_ASN1_EOS + were 4 .. 9, conflicting with + ERR_LIB_RSA (= ERR_R_RSA_LIB) + ... + ERR_LIB_PEM (= ERR_R_PEM_LIB). + They are now 58 .. 63 (i.e., just below ERR_R_FATAL). + + Add new error code 'ERR_R_INTERNAL_ERROR'. + [Bodo Moeller] + + *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock + suffices. + [Bodo Moeller] + + *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This + sets the subject name for a new request or supersedes the + subject name in a given request. Formats that can be parsed are + 'CN=Some Name, OU=myOU, C=IT' + and + 'CN=Some Name/OU=myOU/C=IT'. + + Add options '-batch' and '-verbose' to 'openssl req'. + [Massimiliano Pala ] + + *) Introduce the possibility to access global variables through + functions on platform were that's the best way to handle exporting + global variables in shared libraries. To enable this functionality, + one must configure with "EXPORT_VAR_AS_FN" or defined the C macro + "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter + is normally done by Configure or something similar). + + To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL + in the source file (foo.c) like this: + + OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; + OPENSSL_IMPLEMENT_GLOBAL(double,bar); + + To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL + and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: + + OPENSSL_DECLARE_GLOBAL(int,foo); + #define foo OPENSSL_GLOBAL_REF(foo) + OPENSSL_DECLARE_GLOBAL(double,bar); + #define bar OPENSSL_GLOBAL_REF(bar) + + The #defines are very important, and therefore so is including the + header file everywhere where the defined globals are used. + + The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition + of ASN.1 items, but that structure is a bit different. + + The largest change is in util/mkdef.pl which has been enhanced with + better and easier to understand logic to choose which symbols should + go into the Windows .def files as well as a number of fixes and code + cleanup (among others, algorithm keywords are now sorted + lexicographically to avoid constant rewrites). + [Richard Levitte] + + *) In BN_div() keep a copy of the sign of 'num' before writing the + result to 'rm' because if rm==num the value will be overwritten + and produce the wrong result if 'num' is negative: this caused + problems with BN_mod() and BN_nnmod(). + [Steve Henson] + + *) Function OCSP_request_verify(). This checks the signature on an + OCSP request and verifies the signer certificate. The signer + certificate is just checked for a generic purpose and OCSP request + trust settings. + [Steve Henson] + + *) Add OCSP_check_validity() function to check the validity of OCSP + responses. OCSP responses are prepared in real time and may only + be a few seconds old. Simply checking that the current time lies + between thisUpdate and nextUpdate max reject otherwise valid responses + caused by either OCSP responder or client clock inaccuracy. Instead + we allow thisUpdate and nextUpdate to fall within a certain period of + the current time. The age of the response can also optionally be + checked. Two new options -validity_period and -status_age added to + ocsp utility. + [Steve Henson] + + *) If signature or public key algorithm is unrecognized print out its + OID rather that just UNKNOWN. + [Steve Henson] + + *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and + OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate + ID to be generated from the issuer certificate alone which can then be + passed to OCSP_id_issuer_cmp(). + [Steve Henson] + + *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new + ASN1 modules to export functions returning ASN1_ITEM pointers + instead of the ASN1_ITEM structures themselves. This adds several + new macros which allow the underlying ASN1 function/structure to + be accessed transparently. As a result code should not use ASN1_ITEM + references directly (such as &X509_it) but instead use the relevant + macros (such as ASN1_ITEM_rptr(X509)). This option is to allow + use of the new ASN1 code on platforms where exporting structures + is problematical (for example in shared libraries) but exporting + functions returning pointers to structures is not. + [Steve Henson] + + *) Add support for overriding the generation of SSL/TLS session IDs. + These callbacks can be registered either in an SSL_CTX or per SSL. + The purpose of this is to allow applications to control, if they wish, + the arbitrary values chosen for use as session IDs, particularly as it + can be useful for session caching in multiple-server environments. A + command-line switch for testing this (and any client code that wishes + to use such a feature) has been added to "s_server". + [Geoff Thorpe, Lutz Jaenicke] + + *) Modify mkdef.pl to recognise and parse preprocessor conditionals + of the form '#if defined(...) || defined(...) || ...' and + '#if !defined(...) && !defined(...) && ...'. This also avoids + the growing number of special cases it was previously handling. + [Richard Levitte] + + *) Make all configuration macros available for application by making + sure they are available in opensslconf.h, by giving them names starting + with "OPENSSL_" to avoid conflicts with other packages and by making + sure e_os2.h will cover all platform-specific cases together with + opensslconf.h. + Additionally, it is now possible to define configuration/platform- + specific names (called "system identities"). In the C code, these + are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another + macro with the name beginning with "OPENSSL_SYS_", which is determined + from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on + what is available. + [Richard Levitte] + + *) New option -set_serial to 'req' and 'x509' this allows the serial + number to use to be specified on the command line. Previously self + signed certificates were hard coded with serial number 0 and the + CA options of 'x509' had to use a serial number in a file which was + auto incremented. + [Steve Henson] + + *) New options to 'ca' utility to support V2 CRL entry extensions. + Currently CRL reason, invalidity date and hold instruction are + supported. Add new CRL extensions to V3 code and some new objects. + [Steve Henson] + + *) New function EVP_CIPHER_CTX_set_padding() this is used to + disable standard block padding (aka PKCS#5 padding) in the EVP + API, which was previously mandatory. This means that the data is + not padded in any way and so the total length much be a multiple + of the block size, otherwise an error occurs. + [Steve Henson] + + *) Initial (incomplete) OCSP SSL support. + [Steve Henson] + + *) New function OCSP_parse_url(). This splits up a URL into its host, + port and path components: primarily to parse OCSP URLs. New -url + option to ocsp utility. + [Steve Henson] + + *) New nonce behavior. The return value of OCSP_check_nonce() now + reflects the various checks performed. Applications can decide + whether to tolerate certain situations such as an absent nonce + in a response when one was present in a request: the ocsp application + just prints out a warning. New function OCSP_add1_basic_nonce() + this is to allow responders to include a nonce in a response even if + the request is nonce-less. + [Steve Henson] + + *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are + skipped when using openssl x509 multiple times on a single input file, + e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) ] + + *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates + passed by the function are trusted implicitly. If any of them signed the + response then it is assumed to be valid and is not verified. + [Steve Henson] + + *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT + to data. This was previously part of the PKCS7 ASN1 code. This + was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. + [Steve Henson, reported by Kenneth R. Robinette + ] + + *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 + routines: without these tracing memory leaks is very painful. + Fix leaks in PKCS12 and PKCS7 routines. + [Steve Henson] + + *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). + Previously it initialised the 'type' argument to V_ASN1_UTCTIME which + effectively meant GeneralizedTime would never be used. Now it + is initialised to -1 but X509_time_adj() now has to check the value + and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or + V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. + [Steve Henson, reported by Kenneth R. Robinette + ] + + *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously + result in a zero length in the ASN1_INTEGER structure which was + not consistent with the structure when d2i_ASN1_INTEGER() was used + and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() + to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() + where it did not print out a minus for negative ASN1_INTEGER. + [Steve Henson] + + *) Add summary printout to ocsp utility. The various functions which + convert status values to strings have been renamed to: + OCSP_response_status_str(), OCSP_cert_status_str() and + OCSP_crl_reason_str() and are no longer static. New options + to verify nonce values and to disable verification. OCSP response + printout format cleaned up. + [Steve Henson] + + *) Add additional OCSP certificate checks. These are those specified + in RFC2560. This consists of two separate checks: the CA of the + certificate being checked must either be the OCSP signer certificate + or the issuer of the OCSP signer certificate. In the latter case the + OCSP signer certificate must contain the OCSP signing extended key + usage. This check is performed by attempting to match the OCSP + signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash + in the OCSP_CERTID structures of the response. + [Steve Henson] + + *) Initial OCSP certificate verification added to OCSP_basic_verify() + and related routines. This uses the standard OpenSSL certificate + verify routines to perform initial checks (just CA validity) and + to obtain the certificate chain. Then additional checks will be + performed on the chain. Currently the root CA is checked to see + if it is explicitly trusted for OCSP signing. This is used to set + a root CA as a global signing root: that is any certificate that + chains to that CA is an acceptable OCSP signing certificate. + [Steve Henson] + + *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 + extensions from a separate configuration file. + As when reading extensions from the main configuration file, + the '-extensions ...' option may be used for specifying the + section to use. + [Massimiliano Pala ] + + *) New OCSP utility. Allows OCSP requests to be generated or + read. The request can be sent to a responder and the output + parsed, outputed or printed in text form. Not complete yet: + still needs to check the OCSP response validity. + [Steve Henson] + + *) New subcommands for 'openssl ca': + 'openssl ca -status ' prints the status of the cert with + the given serial number (according to the index file). + 'openssl ca -updatedb' updates the expiry status of certificates + in the index file. + [Massimiliano Pala ] + + *) New '-newreq-nodes' command option to CA.pl. This is like + '-newreq', but calls 'openssl req' with the '-nodes' option + so that the resulting key is not encrypted. + [Damien Miller ] + + *) New configuration for the GNU Hurd. + [Jonathan Bartlett via Richard Levitte] + + *) Initial code to implement OCSP basic response verify. This + is currently incomplete. Currently just finds the signer's + certificate and verifies the signature on the response. + [Steve Henson] + + *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in + value of OPENSSLDIR. This is available via the new '-d' option + to 'openssl version', and is also included in 'openssl version -a'. + [Bodo Moeller] + + *) Allowing defining memory allocation callbacks that will be given + file name and line number information in additional arguments + (a const char* and an int). The basic functionality remains, as + well as the original possibility to just replace malloc(), + realloc() and free() by functions that do not know about these + additional arguments. To register and find out the current + settings for extended allocation functions, the following + functions are provided: + + CRYPTO_set_mem_ex_functions + CRYPTO_set_locked_mem_ex_functions + CRYPTO_get_mem_ex_functions + CRYPTO_get_locked_mem_ex_functions + + These work the same way as CRYPTO_set_mem_functions and friends. + CRYPTO_get_[locked_]mem_functions now writes 0 where such an + extended allocation function is enabled. + Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where + a conventional allocation function is enabled. + [Richard Levitte, Bodo Moeller] + + *) Finish off removing the remaining LHASH function pointer casts. + There should no longer be any prototype-casting required when using + the LHASH abstraction, and any casts that remain are "bugs". See + the callback types and macros at the head of lhash.h for details + (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). + [Geoff Thorpe] + + *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. + If /dev/[u]random devices are not available or do not return enough + entropy, EGD style sockets (served by EGD or PRNGD) will automatically + be queried. + The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and + /etc/entropy will be queried once each in this sequence, quering stops + when enough entropy was collected without querying more sockets. + [Lutz Jaenicke] + + *) Change the Unix RAND_poll() variant to be able to poll several + random devices, as specified by DEVRANDOM, until a sufficient amount + of data has been collected. We spend at most 10 ms on each file + (select timeout) and read in non-blocking mode. DEVRANDOM now + defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" + (previously it was just the string "/dev/urandom"), so on typical + platforms the 10 ms delay will never occur. + Also separate out the Unix variant to its own file, rand_unix.c. + For VMS, there's a currently-empty rand_vms.c. + [Richard Levitte] + + *) Move OCSP client related routines to ocsp_cl.c. These + provide utility functions which an application needing + to issue a request to an OCSP responder and analyse the + response will typically need: as opposed to those which an + OCSP responder itself would need which will be added later. + + OCSP_request_sign() signs an OCSP request with an API similar + to PKCS7_sign(). OCSP_response_status() returns status of OCSP + response. OCSP_response_get1_basic() extracts basic response + from response. OCSP_resp_find_status(): finds and extracts status + information from an OCSP_CERTID structure (which will be created + when the request structure is built). These are built from lower + level functions which work on OCSP_SINGLERESP structures but + wont normally be used unless the application wishes to examine + extensions in the OCSP response for example. + + Replace nonce routines with a pair of functions. + OCSP_request_add1_nonce() adds a nonce value and optionally + generates a random value. OCSP_check_nonce() checks the + validity of the nonce in an OCSP response. + [Steve Henson] + + *) Change function OCSP_request_add() to OCSP_request_add0_id(). + This doesn't copy the supplied OCSP_CERTID and avoids the + need to free up the newly created id. Change return type + to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. + This can then be used to add extensions to the request. + Deleted OCSP_request_new(), since most of its functionality + is now in OCSP_REQUEST_new() (and the case insensitive name + clash) apart from the ability to set the request name which + will be added elsewhere. + [Steve Henson] + + *) Update OCSP API. Remove obsolete extensions argument from + various functions. Extensions are now handled using the new + OCSP extension code. New simple OCSP HTTP function which + can be used to send requests and parse the response. + [Steve Henson] + + *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new + ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN + uses the special reorder version of SET OF to sort the attributes + and reorder them to match the encoded order. This resolves a long + standing problem: a verify on a PKCS7 structure just after signing + it used to fail because the attribute order did not match the + encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: + it uses the received order. This is necessary to tolerate some broken + software that does not order SET OF. This is handled by encoding + as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) + to produce the required SET OF. + [Steve Henson] + + *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and + OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header + files to get correct declarations of the ASN.1 item variables. + [Richard Levitte] + + *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many + PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: + asn1_check_tlen() would sometimes attempt to use 'ctx' when it was + NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). + New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant + ASN1_ITEM and no wrapper functions. + [Steve Henson] + + *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These + replace the old function pointer based I/O routines. Change most of + the *_d2i_bio() and *_d2i_fp() functions to use these. + [Steve Henson] + + *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor + lines, recognice more "algorithms" that can be deselected, and make + it complain about algorithm deselection that isn't recognised. + [Richard Levitte] + + *) New ASN1 functions to handle dup, sign, verify, digest, pack and + unpack operations in terms of ASN1_ITEM. Modify existing wrappers + to use new functions. Add NO_ASN1_OLD which can be set to remove + some old style ASN1 functions: this can be used to determine if old + code will still work when these eventually go away. + [Steve Henson] + + *) New extension functions for OCSP structures, these follow the + same conventions as certificates and CRLs. + [Steve Henson] + + *) New function X509V3_add1_i2d(). This automatically encodes and + adds an extension. Its behaviour can be customised with various + flags to append, replace or delete. Various wrappers added for + certifcates and CRLs. + [Steve Henson] + + *) Fix to avoid calling the underlying ASN1 print routine when + an extension cannot be parsed. Correct a typo in the + OCSP_SERVICELOC extension. Tidy up print OCSP format. + [Steve Henson] + + *) Make mkdef.pl parse some of the ASN1 macros and add apropriate + entries for variables. + [Steve Henson] + + *) Add functionality to apps/openssl.c for detecting locking + problems: As the program is single-threaded, all we have + to do is register a locking callback using an array for + storing which locks are currently held by the program. + [Bodo Moeller] + + *) Use a lock around the call to CRYPTO_get_ex_new_index() in + SSL_get_ex_data_X509_STORE_idx(), which is used in + ssl_verify_cert_chain() and thus can be called at any time + during TLS/SSL handshakes so that thread-safety is essential. + Unfortunately, the ex_data design is not at all suited + for multi-threaded use, so it probably should be abolished. + [Bodo Moeller] + + *) Added Broadcom "ubsec" ENGINE to OpenSSL. + [Broadcom, tweaked and integrated by Geoff Thorpe] + + *) Move common extension printing code to new function + X509V3_print_extensions(). Reorganise OCSP print routines and + implement some needed OCSP ASN1 functions. Add OCSP extensions. + [Steve Henson] + + *) New function X509_signature_print() to remove duplication in some + print routines. + [Steve Henson] + + *) Add a special meaning when SET OF and SEQUENCE OF flags are both + set (this was treated exactly the same as SET OF previously). This + is used to reorder the STACK representing the structure to match the + encoding. This will be used to get round a problem where a PKCS7 + structure which was signed could not be verified because the STACK + order did not reflect the encoded order. + [Steve Henson] + + *) Reimplement the OCSP ASN1 module using the new code. + [Steve Henson] + + *) Update the X509V3 code to permit the use of an ASN1_ITEM structure + for its ASN1 operations. The old style function pointers still exist + for now but they will eventually go away. + [Steve Henson] + + *) Merge in replacement ASN1 code from the ASN1 branch. This almost + completely replaces the old ASN1 functionality with a table driven + encoder and decoder which interprets an ASN1_ITEM structure describing + the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is + largely maintained. Almost all of the old asn1_mac.h macro based ASN1 + has also been converted to the new form. + [Steve Henson] + + *) Change BN_mod_exp_recp so that negative moduli are tolerated + (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set + so that BN_mod_exp_mont and BN_mod_exp_mont_word work + for negative moduli. + [Bodo Moeller] + + *) Fix BN_uadd and BN_usub: Always return non-negative results instead + of not touching the result's sign bit. + [Bodo Moeller] + + *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be + set. + [Bodo Moeller] + + *) Changed the LHASH code to use prototypes for callbacks, and created + macros to declare and implement thin (optionally static) functions + that provide type-safety and avoid function pointer casting for the + type-specific callbacks. + [Geoff Thorpe] + + *) Added Kerberos Cipher Suites to be used with TLS, as written in + RFC 2712. + [Veers Staats , + Jeffrey Altman , via Richard Levitte] + + *) Reformat the FAQ so the different questions and answers can be divided + in sections depending on the subject. + [Richard Levitte] + + *) Have the zlib compression code load ZLIB.DLL dynamically under + Windows. + [Richard Levitte] + + *) New function BN_mod_sqrt for computing square roots modulo a prime + (using the probabilistic Tonelli-Shanks algorithm unless + p == 3 (mod 4) or p == 5 (mod 8), which are cases that can + be handled deterministically). + [Lenka Fibikova , Bodo Moeller] + + *) Make BN_mod_inverse faster by explicitly handling small quotients + in the Euclid loop. (Speed gain about 20% for small moduli [256 or + 512 bits], about 30% for larger ones [1024 or 2048 bits].) + [Bodo Moeller] + + *) New function BN_kronecker. + [Bodo Moeller] + + *) Fix BN_gcd so that it works on negative inputs; the result is + positive unless both parameters are zero. + Previously something reasonably close to an infinite loop was + possible because numbers could be growing instead of shrinking + in the implementation of Euclid's algorithm. + [Bodo Moeller] + + *) Fix BN_is_word() and BN_is_one() macros to take into account the + sign of the number in question. + + Fix BN_is_word(a,w) to work correctly for w == 0. + + The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w) + because its test if the absolute value of 'a' equals 'w'. + Note that BN_abs_is_word does *not* handle w == 0 reliably; + it exists mostly for use in the implementations of BN_is_zero(), + BN_is_one(), and BN_is_word(). + [Bodo Moeller] + + *) New function BN_swap. + [Bodo Moeller] + + *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that + the exponentiation functions are more likely to produce reasonable + results on negative inputs. + [Bodo Moeller] + + *) Change BN_mod_mul so that the result is always non-negative. + Previously, it could be negative if one of the factors was negative; + I don't think anyone really wanted that behaviour. + [Bodo Moeller] + + *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c + (except for exponentiation, which stays in crypto/bn/bn_exp.c, + and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c) + and add new functions: + + BN_nnmod + BN_mod_sqr + BN_mod_add + BN_mod_add_quick + BN_mod_sub + BN_mod_sub_quick + BN_mod_lshift1 + BN_mod_lshift1_quick + BN_mod_lshift + BN_mod_lshift_quick + + These functions always generate non-negative results. + + BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r + such that |m| < r < 0, BN_nnmod will output rem + |m| instead). + + BN_mod_XXX_quick(r, a, [b,] m) generates the same result as + BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b] + be reduced modulo m. + [Lenka Fibikova , Bodo Moeller] + +#if 0 + The following entry accidentily appeared in the CHANGES file + distributed with OpenSSL 0.9.7. The modifications described in + it do *not* apply to OpenSSL 0.9.7. + + *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there + was actually never needed) and in BN_mul(). The removal in BN_mul() + required a small change in bn_mul_part_recursive() and the addition + of the functions bn_cmp_part_words(), bn_sub_part_words() and + bn_add_part_words(), which do the same thing as bn_cmp_words(), + bn_sub_words() and bn_add_words() except they take arrays with + differing sizes. + [Richard Levitte] +#endif + + *) In 'openssl passwd', verify passwords read from the terminal + unless the '-salt' option is used (which usually means that + verification would just waste user's time since the resulting + hash is going to be compared with some given password hash) + or the new '-noverify' option is used. + + This is an incompatible change, but it does not affect + non-interactive use of 'openssl passwd' (passwords on the command + line, '-stdin' option, '-in ...' option) and thus should not + cause any problems. + [Bodo Moeller] + + *) Remove all references to RSAref, since there's no more need for it. + [Richard Levitte] + + *) Make DSO load along a path given through an environment variable + (SHLIB_PATH) with shl_load(). + [Richard Levitte] + + *) Constify the ENGINE code as a result of BIGNUM constification. + Also constify the RSA code and most things related to it. In a + few places, most notable in the depth of the ASN.1 code, ugly + casts back to non-const were required (to be solved at a later + time) + [Richard Levitte] + + *) Make it so the openssl application has all engines loaded by default. + [Richard Levitte] + + *) Constify the BIGNUM routines a little more. + [Richard Levitte] + + *) Add the following functions: + + ENGINE_load_cswift() + ENGINE_load_chil() + ENGINE_load_atalla() + ENGINE_load_nuron() + ENGINE_load_builtin_engines() + + That way, an application can itself choose if external engines that + are built-in in OpenSSL shall ever be used or not. The benefit is + that applications won't have to be linked with libdl or other dso + libraries unless it's really needed. + + Changed 'openssl engine' to load all engines on demand. + Changed the engine header files to avoid the duplication of some + declarations (they differed!). + [Richard Levitte] + + *) 'openssl engine' can now list capabilities. + [Richard Levitte] + + *) Better error reporting in 'openssl engine'. + [Richard Levitte] + + *) Never call load_dh_param(NULL) in s_server. + [Bodo Moeller] + + *) Add engine application. It can currently list engines by name and + identity, and test if they are actually available. + [Richard Levitte] + + *) Improve RPM specification file by forcing symbolic linking and making + sure the installed documentation is also owned by root.root. + [Damien Miller ] + + *) Give the OpenSSL applications more possibilities to make use of + keys (public as well as private) handled by engines. + [Richard Levitte] + + *) Add OCSP code that comes from CertCo. + [Richard Levitte] + + *) Add VMS support for the Rijndael code. + [Richard Levitte] + + *) Added untested support for Nuron crypto accelerator. + [Ben Laurie] + + *) Add support for external cryptographic devices. This code was + previously distributed separately as the "engine" branch. + [Geoff Thorpe, Richard Levitte] + + *) Rework the filename-translation in the DSO code. It is now possible to + have far greater control over how a "name" is turned into a filename + depending on the operating environment and any oddities about the + different shared library filenames on each system. + [Geoff Thorpe] + + *) Support threads on FreeBSD-elf in Configure. + [Richard Levitte] + + *) Fix for SHA1 assembly problem with MASM: it produces + warnings about corrupt line number information when assembling + with debugging information. This is caused by the overlapping + of two sections. + [Bernd Matthes , Steve Henson] + + *) NCONF changes. + NCONF_get_number() has no error checking at all. As a replacement, + NCONF_get_number_e() is defined (_e for "error checking") and is + promoted strongly. The old NCONF_get_number is kept around for + binary backward compatibility. + Make it possible for methods to load from something other than a BIO, + by providing a function pointer that is given a name instead of a BIO. + For example, this could be used to load configuration data from an + LDAP server. + [Richard Levitte] + + *) Fix for non blocking accept BIOs. Added new I/O special reason + BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs + with non blocking I/O was not possible because no retry code was + implemented. Also added new SSL code SSL_WANT_ACCEPT to cover + this case. + [Steve Henson] + + *) Added the beginnings of Rijndael support. + [Ben Laurie] + + *) Fix for bug in DirectoryString mask setting. Add support for + X509_NAME_print_ex() in 'req' and X509_print_ex() function + to allow certificate printing to more controllable, additional + 'certopt' option to 'x509' to allow new printing options to be + set. + [Steve Henson] + + *) Clean old EAY MD5 hack from e_os.h. + [Richard Levitte] + + Changes between 0.9.6l and 0.9.6m [17 Mar 2004] + + *) Fix null-pointer assignment in do_change_cipher_spec() revealed + by using the Codenomicon TLS Test Tool (CVE-2004-0079) + [Joe Orton, Steve Henson] + + Changes between 0.9.6k and 0.9.6l [04 Nov 2003] + + *) Fix additional bug revealed by the NISCC test suite: + + Stop bug triggering large recursion when presented with + certain ASN.1 tags (CVE-2003-0851) + [Steve Henson] + + Changes between 0.9.6j and 0.9.6k [30 Sep 2003] + + *) Fix various bugs revealed by running the NISCC test suite: + + Stop out of bounds reads in the ASN1 code when presented with + invalid tags (CVE-2003-0543 and CVE-2003-0544). + + If verify callback ignores invalid public key errors don't try to check + certificate signature with the NULL public key. + + [Steve Henson] + + *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate + if the server requested one: as stated in TLS 1.0 and SSL 3.0 + specifications. + [Steve Henson] + + *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional + extra data after the compression methods not only for TLS 1.0 + but also for SSL 3.0 (as required by the specification). + [Bodo Moeller; problem pointed out by Matthias Loepfe] + + *) Change X509_certificate_type() to mark the key as exported/exportable + when it's 512 *bits* long, not 512 bytes. + [Richard Levitte] + + Changes between 0.9.6i and 0.9.6j [10 Apr 2003] + + *) Countermeasure against the Klima-Pokorny-Rosa extension of + Bleichbacher's attack on PKCS #1 v1.5 padding: treat + a protocol version number mismatch like a decryption error + in ssl3_get_client_key_exchange (ssl/s3_srvr.c). + [Bodo Moeller] + + *) Turn on RSA blinding by default in the default implementation + to avoid a timing attack.

This is apparently the reason for the libsafe "errors" + but the code is actually correct. + [Steve Henson] + + *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent + Bleichenbacher's DSA attack. + Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits + to be set and top=0 forces the highest bit to be set; top=-1 is new + and leaves the highest bit random. + [Ulf Moeller, Bodo Moeller] + + *) In the NCONF_...-based implementations for CONF_... queries + (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using + a temporary CONF structure with the data component set to NULL + (which gives segmentation faults in lh_retrieve). + Instead, use NULL for the CONF pointer in CONF_get_string and + CONF_get_number (which may use environment variables) and directly + return NULL from CONF_get_section. + [Bodo Moeller] + + *) Fix potential buffer overrun for EBCDIC. + [Ulf Moeller] + + *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign + keyUsage if basicConstraints absent for a CA. + [Steve Henson] + + *) Make SMIME_write_PKCS7() write mail header values with a format that + is more generally accepted (no spaces before the semicolon), since + some programs can't parse those values properly otherwise. Also make + sure BIO's that break lines after each write do not create invalid + headers. + [Richard Levitte] + + *) Make the CRL encoding routines work with empty SEQUENCE OF. The + macros previously used would not encode an empty SEQUENCE OF + and break the signature. + [Steve Henson] + [This change does not apply to 0.9.7.] + + *) Zero the premaster secret after deriving the master secret in + DH ciphersuites. + [Steve Henson] + + *) Add some EVP_add_digest_alias registrations (as found in + OpenSSL_add_all_digests()) to SSL_library_init() + aka OpenSSL_add_ssl_algorithms().

(Re-used sessions on the client side + always resulted in verify_result==X509_V_OK, not using the original + result of the server certificate verification.) + [Lutz Jaenicke] + + *) Fix ssl3_pending: If the record in s->s3->rrec is not of type + SSL3_RT_APPLICATION_DATA, return 0. + Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true. + [Bodo Moeller] + + *) Fix SSL_peek: + Both ssl2_peek and ssl3_peek, which were totally broken in earlier + releases, have been re-implemented by renaming the previous + implementations of ssl2_read and ssl3_read to ssl2_read_internal + and ssl3_read_internal, respectively, and adding 'peek' parameters + to them. The new ssl[23]_{read,peek} functions are calls to + ssl[23]_read_internal with the 'peek' flag set appropriately. + A 'peek' parameter has also been added to ssl3_read_bytes, which + does the actual work for ssl3_read_internal. + [Bodo Moeller] + + *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling + the method-specific "init()" handler. Also clean up ex_data after + calling the method-specific "finish()" handler. Previously, this was + happening the other way round. + [Geoff Thorpe] + + *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16. + The previous value, 12, was not always sufficient for BN_mod_exp(). + [Bodo Moeller] + + *) Make sure that shared libraries get the internal name engine with + the full version number and not just 0. This should mark the + shared libraries as not backward compatible. Of course, this should + be changed again when we can guarantee backward binary compatibility. + [Richard Levitte] + + *) Fix typo in get_cert_by_subject() in by_dir.c + [Jean-Marc Desperrier ] + + *) Rework the system to generate shared libraries: + + - Make note of the expected extension for the shared libraries and + if there is a need for symbolic links from for example libcrypto.so.0 + to libcrypto.so.0.9.7. There is extended info in Configure for + that. + + - Make as few rebuilds of the shared libraries as possible. + + - Still avoid linking the OpenSSL programs with the shared libraries. + + - When installing, install the shared libraries separately from the + static ones. + [Richard Levitte] + + *) Fix SSL_CTX_set_read_ahead macro to actually use its argument. + + Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new + and not in SSL_clear because the latter is also used by the + accept/connect functions; previously, the settings made by + SSL_set_read_ahead would be lost during the handshake. + [Bodo Moeller; problems reported by Anders Gertz ] + + *) Correct util/mkdef.pl to be selective about disabled algorithms. + Previously, it would create entries for disableed algorithms no + matter what. + [Richard Levitte] + + *) Added several new manual pages for SSL_* function. + [Lutz Jaenicke] + + Changes between 0.9.5a and 0.9.6 [24 Sep 2000] + + *) In ssl23_get_client_hello, generate an error message when faced + with an initial SSL 3.0/TLS record that is too small to contain the + first two bytes of the ClientHello message, i.e. client_version. + (Note that this is a pathologic case that probably has never happened + in real life.) The previous approach was to use the version number + from the record header as a substitute; but our protocol choice + should not depend on that one because it is not authenticated + by the Finished messages. + [Bodo Moeller] + + *) More robust randomness gathering functions for Windows. + [Jeffrey Altman ] + + *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is + not set then we don't setup the error code for issuer check errors + to avoid possibly overwriting other errors which the callback does + handle. If an application does set the flag then we assume it knows + what it is doing and can handle the new informational codes + appropriately. + [Steve Henson] + + *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for + a general "ANY" type, as such it should be able to decode anything + including tagged types. However it didn't check the class so it would + wrongly interpret tagged types in the same way as their universal + counterpart and unknown types were just rejected. Changed so that the + tagged and unknown types are handled in the same way as a SEQUENCE: + that is the encoding is stored intact. There is also a new type + "V_ASN1_OTHER" which is used when the class is not universal, in this + case we have no idea what the actual type is so we just lump them all + together. + [Steve Henson] + + *) On VMS, stdout may very well lead to a file that is written to + in a record-oriented fashion. That means that every write() will + write a separate record, which will be read separately by the + programs trying to read from it. This can be very confusing. + + The solution is to put a BIO filter in the way that will buffer + text until a linefeed is reached, and then write everything a + line at a time, so every record written will be an actual line, + not chunks of lines and not (usually doesn't happen, but I've + seen it once) several lines in one record. BIO_f_linebuffer() is + the answer. + + Currently, it's a VMS-only method, because that's where it has + been tested well enough. + [Richard Levitte] + + *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery, + it can return incorrect results. + (Note: The buggy variant was not enabled in OpenSSL 0.9.5a, + but it was in 0.9.6-beta[12].) + [Bodo Moeller] + + *) Disable the check for content being present when verifying detached + signatures in pk7_smime.c. Some versions of Netscape (wrongly) + include zero length content when signing messages. + [Steve Henson] + + *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR + BIO_ctrl (for BIO pairs). + [Bodo Möller] + + *) Add DSO method for VMS. + [Richard Levitte] + + *) Bug fix: Montgomery multiplication could produce results with the + wrong sign. + [Ulf Möller] + + *) Add RPM specification openssl.spec and modify it to build three + packages. The default package contains applications, application + documentation and run-time libraries. The devel package contains + include files, static libraries and function documentation. The + doc package contains the contents of the doc directory. The original + openssl.spec was provided by Damien Miller . + [Richard Levitte] + + *) Add a large number of documentation files for many SSL routines. + [Lutz Jaenicke ] + + *) Add a configuration entry for Sony News 4. + [NAKAJI Hiroyuki ] + + *) Don't set the two most significant bits to one when generating a + random number < q in the DSA library. + [Ulf Möller] + + *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default + behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if + the underlying transport is blocking) if a handshake took place. + (The default behaviour is needed by applications such as s_client + and s_server that use select() to determine when to use SSL_read; + but for applications that know in advance when to expect data, it + just makes things more complicated.) + [Bodo Moeller] + + *) Add RAND_egd_bytes(), which gives control over the number of bytes read + from EGD. + [Ben Laurie] + + *) Add a few more EBCDIC conditionals that make `req' and `x509' + work better on such systems. + [Martin Kraemer ] + + *) Add two demo programs for PKCS12_parse() and PKCS12_create(). + Update PKCS12_parse() so it copies the friendlyName and the + keyid to the certificates aux info. + [Steve Henson] + + *) Fix bug in PKCS7_verify() which caused an infinite loop + if there was more than one signature. + [Sven Uszpelkat ] + + *) Major change in util/mkdef.pl to include extra information + about each symbol, as well as presentig variables as well + as functions. This change means that there's n more need + to rebuild the .num files when some algorithms are excluded. + [Richard Levitte] + + *) Allow the verify time to be set by an application, + rather than always using the current time. + [Steve Henson] + + *) Phase 2 verify code reorganisation. The certificate + verify code now looks up an issuer certificate by a + number of criteria: subject name, authority key id + and key usage. It also verifies self signed certificates + by the same criteria. The main comparison function is + X509_check_issued() which performs these checks. + + Lot of changes were necessary in order to support this + without completely rewriting the lookup code. + + Authority and subject key identifier are now cached. + + The LHASH 'certs' is X509_STORE has now been replaced + by a STACK_OF(X509_OBJECT). This is mainly because an + LHASH can't store or retrieve multiple objects with + the same hash value. + + As a result various functions (which were all internal + use only) have changed to handle the new X509_STORE + structure. This will break anything that messed round + with X509_STORE internally. + + The functions X509_STORE_add_cert() now checks for an + exact match, rather than just subject name. + + The X509_STORE API doesn't directly support the retrieval + of multiple certificates matching a given criteria, however + this can be worked round by performing a lookup first + (which will fill the cache with candidate certificates) + and then examining the cache for matches. This is probably + the best we can do without throwing out X509_LOOKUP + entirely (maybe later...). + + The X509_VERIFY_CTX structure has been enhanced considerably. + + All certificate lookup operations now go via a get_issuer() + callback. Although this currently uses an X509_STORE it + can be replaced by custom lookups. This is a simple way + to bypass the X509_STORE hackery necessary to make this + work and makes it possible to use more efficient techniques + in future. A very simple version which uses a simple + STACK for its trusted certificate store is also provided + using X509_STORE_CTX_trusted_stack(). + + The verify_cb() and verify() callbacks now have equivalents + in the X509_STORE_CTX structure. + + X509_STORE_CTX also has a 'flags' field which can be used + to customise the verify behaviour. + [Steve Henson] + + *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which + excludes S/MIME capabilities. + [Steve Henson] + + *) When a certificate request is read in keep a copy of the + original encoding of the signed data and use it when outputing + again. Signatures then use the original encoding rather than + a decoded, encoded version which may cause problems if the + request is improperly encoded. + [Steve Henson] + + *) For consistency with other BIO_puts implementations, call + buffer_write(b, ...) directly in buffer_puts instead of calling + BIO_write(b, ...). + + In BIO_puts, increment b->num_write as in BIO_write. + [Peter.Sylvester@EdelWeb.fr] + + *) Fix BN_mul_word for the case where the word is 0. (We have to use + BN_zero, we may not return a BIGNUM with an array consisting of + words set to zero.) + [Bodo Moeller] + + *) Avoid calling abort() from within the library when problems are + detected, except if preprocessor symbols have been defined + (such as REF_CHECK, BN_DEBUG etc.). + [Bodo Moeller] + + *) New openssl application 'rsautl'. This utility can be + used for low level RSA operations. DER public key + BIO/fp routines also added. + [Steve Henson] + + *) New Configure entry and patches for compiling on QNX 4. + [Andreas Schneider ] + + *) A demo state-machine implementation was sponsored by + Nuron (http://www.nuron.com/) and is now available in + demos/state_machine. + [Ben Laurie] + + *) New options added to the 'dgst' utility for signature + generation and verification. + [Steve Henson] + + *) Unrecognized PKCS#7 content types are now handled via a + catch all ASN1_TYPE structure. This allows unsupported + types to be stored as a "blob" and an application can + encode and decode it manually. + [Steve Henson] + + *) Fix various signed/unsigned issues to make a_strex.c + compile under VC++. + [Oscar Jacobsson ] + + *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct + length if passed a buffer. ASN1_INTEGER_to_BN failed + if passed a NULL BN and its argument was negative. + [Steve Henson, pointed out by Sven Heiberg ] + + *) Modification to PKCS#7 encoding routines to output definite + length encoding. Since currently the whole structures are in + memory there's not real point in using indefinite length + constructed encoding. However if OpenSSL is compiled with + the flag PKCS7_INDEFINITE_ENCODING the old form is used. + [Steve Henson] + + *) Added BIO_vprintf() and BIO_vsnprintf(). + [Richard Levitte] + + *) Added more prefixes to parse for in the the strings written + through a logging bio, to cover all the levels that are available + through syslog. The prefixes are now: + + PANIC, EMERG, EMR => LOG_EMERG + ALERT, ALR => LOG_ALERT + CRIT, CRI => LOG_CRIT + ERROR, ERR => LOG_ERR + WARNING, WARN, WAR => LOG_WARNING + NOTICE, NOTE, NOT => LOG_NOTICE + INFO, INF => LOG_INFO + DEBUG, DBG => LOG_DEBUG + + and as before, if none of those prefixes are present at the + beginning of the string, LOG_ERR is chosen. + + On Win32, the LOG_* levels are mapped according to this: + + LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE + LOG_WARNING => EVENTLOG_WARNING_TYPE + LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE + + [Richard Levitte] + + *) Made it possible to reconfigure with just the configuration + argument "reconf" or "reconfigure". The command line arguments + are stored in Makefile.ssl in the variable CONFIGURE_ARGS, + and are retrieved from there when reconfiguring. + [Richard Levitte] + + *) MD4 implemented. + [Assar Westerlund , Richard Levitte] + + *) Add the arguments -CAfile and -CApath to the pkcs12 utility. + [Richard Levitte] + + *) The obj_dat.pl script was messing up the sorting of object + names. The reason was that it compared the quoted version + of strings as a result "OCSP" > "OCSP Signing" because + " > SPACE. Changed script to store unquoted versions of + names and add quotes on output. It was also omitting some + names from the lookup table if they were given a default + value (that is if SN is missing it is given the same + value as LN and vice versa), these are now added on the + grounds that if an object has a name we should be able to + look it up. Finally added warning output when duplicate + short or long names are found. + [Steve Henson] + + *) Changes needed for Tandem NSK. + [Scott Uroff ] + + *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in + RSA_padding_check_SSLv23(), special padding was never detected + and thus the SSL 3.0/TLS 1.0 countermeasure against protocol + version rollback attacks was not effective. + + In s23_clnt.c, don't use special rollback-attack detection padding + (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the + client; similarly, in s23_srvr.c, don't do the rollback check if + SSL 2.0 is the only protocol enabled in the server. + [Bodo Moeller] + + *) Make it possible to get hexdumps of unprintable data with 'openssl + asn1parse'. By implication, the functions ASN1_parse_dump() and + BIO_dump_indent() are added. + [Richard Levitte] + + *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex() + these print out strings and name structures based on various + flags including RFC2253 support and proper handling of + multibyte characters. Added options to the 'x509' utility + to allow the various flags to be set. + [Steve Henson] + + *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME. + Also change the functions X509_cmp_current_time() and + X509_gmtime_adj() work with an ASN1_TIME structure, + this will enable certificates using GeneralizedTime in validity + dates to be checked. + [Steve Henson] + + *) Make the NEG_PUBKEY_BUG code (which tolerates invalid + negative public key encodings) on by default, + NO_NEG_PUBKEY_BUG can be set to disable it. + [Steve Henson] + + *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT + content octets. An i2c_ASN1_OBJECT is unnecessary because + the encoding can be trivially obtained from the structure. + [Steve Henson] + + *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock), + not read locks (CRYPTO_r_[un]lock). + [Bodo Moeller] + + *) A first attempt at creating official support for shared + libraries through configuration. I've kept it so the + default is static libraries only, and the OpenSSL programs + are always statically linked for now, but there are + preparations for dynamic linking in place. + This has been tested on Linux and Tru64. + [Richard Levitte] + + *) Randomness polling function for Win9x, as described in: + Peter Gutmann, Software Generation of Practically Strong + Random Numbers. + [Ulf Möller] + + *) Fix so PRNG is seeded in req if using an already existing + DSA key. + [Steve Henson] + + *) New options to smime application. -inform and -outform + allow alternative formats for the S/MIME message including + PEM and DER. The -content option allows the content to be + specified separately. This should allow things like Netscape + form signing output easier to verify. + [Steve Henson] + + *) Fix the ASN1 encoding of tags using the 'long form'. + [Steve Henson] + + *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT + STRING types. These convert content octets to and from the + underlying type. The actual tag and length octets are + already assumed to have been read in and checked. These + are needed because all other string types have virtually + identical handling apart from the tag. By having versions + of the ASN1 functions that just operate on content octets + IMPLICIT tagging can be handled properly. It also allows + the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED + and ASN1_INTEGER are identical apart from the tag. + [Steve Henson] + + *) Change the handling of OID objects as follows: + + - New object identifiers are inserted in objects.txt, following + the syntax given in objects.README. + - objects.pl is used to process obj_mac.num and create a new + obj_mac.h. + - obj_dat.pl is used to create a new obj_dat.h, using the data in + obj_mac.h. + + This is currently kind of a hack, and the perl code in objects.pl + isn't very elegant, but it works as I intended. The simplest way + to check that it worked correctly is to look in obj_dat.h and + check the array nid_objs and make sure the objects haven't moved + around (this is important!). Additions are OK, as well as + consistent name changes. + [Richard Levitte] + + *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1'). + [Bodo Moeller] + + *) Addition of the command line parameter '-rand file' to 'openssl req'. + The given file adds to whatever has already been seeded into the + random pool through the RANDFILE configuration file option or + environment variable, or the default random state file. + [Richard Levitte] + + *) mkstack.pl now sorts each macro group into lexical order. + Previously the output order depended on the order the files + appeared in the directory, resulting in needless rewriting + of safestack.h . + [Steve Henson] + + *) Patches to make OpenSSL compile under Win32 again. Mostly + work arounds for the VC++ problem that it treats func() as + func(void). Also stripped out the parts of mkdef.pl that + added extra typesafe functions: these no longer exist. + [Steve Henson] + + *) Reorganisation of the stack code. The macros are now all + collected in safestack.h . Each macro is defined in terms of + a "stack macro" of the form SKM_(type, a, b). The + DEBUG_SAFESTACK is now handled in terms of function casts, + this has the advantage of retaining type safety without the + use of additional functions. If DEBUG_SAFESTACK is not defined + then the non typesafe macros are used instead. Also modified the + mkstack.pl script to handle the new form. Needs testing to see + if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK + the default if no major problems. Similar behaviour for ASN1_SET_OF + and PKCS12_STACK_OF. + [Steve Henson] + + *) When some versions of IIS use the 'NET' form of private key the + key derivation algorithm is different. Normally MD5(password) is + used as a 128 bit RC4 key. In the modified case + MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some + new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same + as the old Netscape_RSA functions except they have an additional + 'sgckey' parameter which uses the modified algorithm. Also added + an -sgckey command line option to the rsa utility. Thanks to + Adrian Peck for posting details of the modified + algorithm to openssl-dev. + [Steve Henson] + + *) The evp_local.h macros were using 'c.##kname' which resulted in + invalid expansion on some systems (SCO 5.0.5 for example). + Corrected to 'c.kname'. + [Phillip Porch ] + + *) New X509_get1_email() and X509_REQ_get1_email() functions that return + a STACK of email addresses from a certificate or request, these look + in the subject name and the subject alternative name extensions and + omit any duplicate addresses. + [Steve Henson] + + *) Re-implement BN_mod_exp2_mont using independent (and larger) windows. + This makes DSA verification about 2 % faster. + [Bodo Moeller] + + *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5 + (meaning that now 2^5 values will be precomputed, which is only 4 KB + plus overhead for 1024 bit moduli). + This makes exponentiations about 0.5 % faster for 1024 bit + exponents (as measured by "openssl speed rsa2048"). + [Bodo Moeller] + + *) Rename memory handling macros to avoid conflicts with other + software: + Malloc => OPENSSL_malloc + Malloc_locked => OPENSSL_malloc_locked + Realloc => OPENSSL_realloc + Free => OPENSSL_free + [Richard Levitte] + + *) New function BN_mod_exp_mont_word for small bases (roughly 15% + faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange). + [Bodo Moeller] + + *) CygWin32 support. + [John Jarvie ] + + *) The type-safe stack code has been rejigged. It is now only compiled + in when OpenSSL is configured with the DEBUG_SAFESTACK option and + by default all type-specific stack functions are "#define"d back to + standard stack functions. This results in more streamlined output + but retains the type-safety checking possibilities of the original + approach. + [Geoff Thorpe] + + *) The STACK code has been cleaned up, and certain type declarations + that didn't make a lot of sense have been brought in line. This has + also involved a cleanup of sorts in safestack.h to more correctly + map type-safe stack functions onto their plain stack counterparts. + This work has also resulted in a variety of "const"ifications of + lots of the code, especially "_cmp" operations which should normally + be prototyped with "const" parameters anyway. + [Geoff Thorpe] + + *) When generating bytes for the first time in md_rand.c, 'stir the pool' + by seeding with STATE_SIZE dummy bytes (with zero entropy count). + (The PRNG state consists of two parts, the large pool 'state' and 'md', + where all of 'md' is used each time the PRNG is used, but 'state' + is used only indexed by a cyclic counter. As entropy may not be + well distributed from the beginning, 'md' is important as a + chaining variable. However, the output function chains only half + of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains + all of 'md', and seeding with STATE_SIZE dummy bytes will result + in all of 'state' being rewritten, with the new values depending + on virtually all of 'md'. This overcomes the 80 bit limitation.) + [Bodo Moeller] + + *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when + the handshake is continued after ssl_verify_cert_chain(); + otherwise, if SSL_VERIFY_NONE is set, remaining error codes + can lead to 'unexplainable' connection aborts later. + [Bodo Moeller; problem tracked down by Lutz Jaenicke] + + *) Major EVP API cipher revision. + Add hooks for extra EVP features. This allows various cipher + parameters to be set in the EVP interface. Support added for variable + key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and + setting of RC2 and RC5 parameters. + + Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length + ciphers. + + Remove lots of duplicated code from the EVP library. For example *every* + cipher init() function handles the 'iv' in the same way according to the + cipher mode. They also all do nothing if the 'key' parameter is NULL and + for CFB and OFB modes they zero ctx->num. + + New functionality allows removal of S/MIME code RC2 hack. + + Most of the routines have the same form and so can be declared in terms + of macros. + + By shifting this to the top level EVP_CipherInit() it can be removed from + all individual ciphers. If the cipher wants to handle IVs or keys + differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT + flags. + + Change lots of functions like EVP_EncryptUpdate() to now return a + value: although software versions of the algorithms cannot fail + any installed hardware versions can. + [Steve Henson] + + *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if + this option is set, tolerate broken clients that send the negotiated + protocol version number instead of the requested protocol version + number. + [Bodo Moeller] + + *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag; + i.e. non-zero for export ciphersuites, zero otherwise. + Previous versions had this flag inverted, inconsistent with + rsa_tmp_cb (..._TMP_RSA_CB). + [Bodo Moeller; problem reported by Amit Chopra] + + *) Add missing DSA library text string. Work around for some IIS + key files with invalid SEQUENCE encoding. + [Steve Henson] + + *) Add a document (doc/standards.txt) that list all kinds of standards + and so on that are implemented in OpenSSL. + [Richard Levitte] + + *) Enhance c_rehash script. Old version would mishandle certificates + with the same subject name hash and wouldn't handle CRLs at all. + Added -fingerprint option to crl utility, to support new c_rehash + features. + [Steve Henson] + + *) Eliminate non-ANSI declarations in crypto.h and stack.h. + [Ulf Möller] + + *) Fix for SSL server purpose checking. Server checking was + rejecting certificates which had extended key usage present + but no ssl client purpose. + [Steve Henson, reported by Rene Grosser ] + + *) Make PKCS#12 code work with no password. The PKCS#12 spec + is a little unclear about how a blank password is handled. + Since the password in encoded as a BMPString with terminating + double NULL a zero length password would end up as just the + double NULL. However no password at all is different and is + handled differently in the PKCS#12 key generation code. NS + treats a blank password as zero length. MSIE treats it as no + password on export: but it will try both on import. We now do + the same: PKCS12_parse() tries zero length and no password if + the password is set to "" or NULL (NULL is now a valid password: + it wasn't before) as does the pkcs12 application. + [Steve Henson] + + *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use + perror when PEM_read_bio_X509_REQ fails, the error message must + be obtained from the error queue. + [Bodo Moeller] + + *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing + it in ERR_remove_state if appropriate, and change ERR_get_state + accordingly to avoid race conditions (this is necessary because + thread_hash is no longer constant once set). + [Bodo Moeller] + + *) Bugfix for linux-elf makefile.one. + [Ulf Möller] + + *) RSA_get_default_method() will now cause a default + RSA_METHOD to be chosen if one doesn't exist already. + Previously this was only set during a call to RSA_new() + or RSA_new_method(NULL) meaning it was possible for + RSA_get_default_method() to return NULL. + [Geoff Thorpe] + + *) Added native name translation to the existing DSO code + that will convert (if the flag to do so is set) filenames + that are sufficiently small and have no path information + into a canonical native form. Eg. "blah" converted to + "libblah.so" or "blah.dll" etc. + [Geoff Thorpe] + + *) New function ERR_error_string_n(e, buf, len) which is like + ERR_error_string(e, buf), but writes at most 'len' bytes + including the 0 terminator. For ERR_error_string_n, 'buf' + may not be NULL. + [Damien Miller , Bodo Moeller] + + *) CONF library reworked to become more general. A new CONF + configuration file reader "class" is implemented as well as a + new functions (NCONF_*, for "New CONF") to handle it. The now + old CONF_* functions are still there, but are reimplemented to + work in terms of the new functions. Also, a set of functions + to handle the internal storage of the configuration data is + provided to make it easier to write new configuration file + reader "classes" (I can definitely see something reading a + configuration file in XML format, for example), called _CONF_*, + or "the configuration storage API"... + + The new configuration file reading functions are: + + NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio, + NCONF_get_section, NCONF_get_string, NCONF_get_numbre + + NCONF_default, NCONF_WIN32 + + NCONF_dump_fp, NCONF_dump_bio + + NCONF_default and NCONF_WIN32 are method (or "class") choosers, + NCONF_new creates a new CONF object. This works in the same way + as other interfaces in OpenSSL, like the BIO interface. + NCONF_dump_* dump the internal storage of the configuration file, + which is useful for debugging. All other functions take the same + arguments as the old CONF_* functions wth the exception of the + first that must be a `CONF *' instead of a `LHASH *'. + + To make it easer to use the new classes with the old CONF_* functions, + the function CONF_set_default_method is provided. + [Richard Levitte] + + *) Add '-tls1' option to 'openssl ciphers', which was already + mentioned in the documentation but had not been implemented. + (This option is not yet really useful because even the additional + experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.) + [Bodo Moeller] + + *) Initial DSO code added into libcrypto for letting OpenSSL (and + OpenSSL-based applications) load shared libraries and bind to + them in a portable way. + [Geoff Thorpe, with contributions from Richard Levitte] + + Changes between 0.9.5 and 0.9.5a [1 Apr 2000] + + *) Make sure _lrotl and _lrotr are only used with MSVC. + + *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status + (the default implementation of RAND_status). + + *) Rename openssl x509 option '-crlext', which was added in 0.9.5, + to '-clrext' (= clear extensions), as intended and documented. + [Bodo Moeller; inconsistency pointed out by Michael Attili + ] + + *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length + was larger than the MD block size. + [Steve Henson, pointed out by Yost William ] + + *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument + fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set() + using the passed key: if the passed key was a private key the result + of X509_print(), for example, would be to print out all the private key + components. + [Steve Henson] + + *) des_quad_cksum() byte order bug fix. + [Ulf Möller, using the problem description in krb4-0.9.7, where + the solution is attributed to Derrick J Brashear ] + + *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly + discouraged. + [Steve Henson, pointed out by Brian Korver ] + + *) For easily testing in shell scripts whether some command + 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX' + returns with exit code 0 iff no command of the given name is available. + 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases, + the output goes to stdout and nothing is printed to stderr. + Additional arguments are always ignored. + + Since for each cipher there is a command of the same name, + the 'no-cipher' compilation switches can be tested this way. + + ('openssl no-XXX' is not able to detect pseudo-commands such + as 'quit', 'list-XXX-commands', or 'no-XXX' itself.) + [Bodo Moeller] + + *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration. + [Bodo Moeller] + + *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE + is set; it will be thrown away anyway because each handshake creates + its own key. + ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition + to parameters -- in previous versions (since OpenSSL 0.9.3) the + 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining + you effectivly got SSL_OP_SINGLE_DH_USE when using this macro. + [Bodo Moeller] + + *) New s_client option -ign_eof: EOF at stdin is ignored, and + 'Q' and 'R' lose their special meanings (quit/renegotiate). + This is part of what -quiet does; unlike -quiet, -ign_eof + does not suppress any output. + [Richard Levitte] + + *) Add compatibility options to the purpose and trust code. The + purpose X509_PURPOSE_ANY is "any purpose" which automatically + accepts a certificate or CA, this was the previous behaviour, + with all the associated security issues. + + X509_TRUST_COMPAT is the old trust behaviour: only and + automatically trust self signed roots in certificate store. A + new trust setting X509_TRUST_DEFAULT is used to specify that + a purpose has no associated trust setting and it should instead + use the value in the default purpose. + [Steve Henson] + + *) Fix the PKCS#8 DSA private key code so it decodes keys again + and fix a memory leak. + [Steve Henson] + + *) In util/mkerr.pl (which implements 'make errors'), preserve + reason strings from the previous version of the .c file, as + the default to have only downcase letters (and digits) in + automatically generated reasons codes is not always appropriate. + [Bodo Moeller] + + *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table + using strerror. Previously, ERR_reason_error_string() returned + library names as reason strings for SYSerr; but SYSerr is a special + case where small numbers are errno values, not library numbers. + [Bodo Moeller] + + *) Add '-dsaparam' option to 'openssl dhparam' application. This + converts DSA parameters into DH parameters. (When creating parameters, + DSA_generate_parameters is used.) + [Bodo Moeller] + + *) Include 'length' (recommended exponent length) in C code generated + by 'openssl dhparam -C'. + [Bodo Moeller] + + *) The second argument to set_label in perlasm was already being used + so couldn't be used as a "file scope" flag. Moved to third argument + which was free. + [Steve Henson] + + *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes + instead of RAND_bytes for encryption IVs and salts. + [Bodo Moeller] + + *) Include RAND_status() into RAND_METHOD instead of implementing + it only for md_rand.c Otherwise replacing the PRNG by calling + RAND_set_rand_method would be impossible. + [Bodo Moeller] + + *) Don't let DSA_generate_key() enter an infinite loop if the random + number generation fails. + [Bodo Moeller] + + *) New 'rand' application for creating pseudo-random output. + [Bodo Moeller] + + *) Added configuration support for Linux/IA64 + [Rolf Haberrecker ] + + *) Assembler module support for Mingw32. + [Ulf Möller] + + *) Shared library support for HPUX (in shlib/). + [Lutz Jaenicke and Anonymous] + + *) Shared library support for Solaris gcc. + [Lutz Behnke ] + + Changes between 0.9.4 and 0.9.5 [28 Feb 2000] + + *) PKCS7_encrypt() was adding text MIME headers twice because they + were added manually and by SMIME_crlf_copy(). + [Steve Henson] + + *) In bntest.c don't call BN_rand with zero bits argument. + [Steve Henson, pointed out by Andrew W. Gray ] + + *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n] + case was implemented. This caused BN_div_recp() to fail occasionally. + [Ulf Möller] + + *) Add an optional second argument to the set_label() in the perl + assembly language builder. If this argument exists and is set + to 1 it signals that the assembler should use a symbol whose + scope is the entire file, not just the current function. This + is needed with MASM which uses the format label:: for this scope. + [Steve Henson, pointed out by Peter Runestig ] + + *) Change the ASN1 types so they are typedefs by default. Before + almost all types were #define'd to ASN1_STRING which was causing + STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING) + for example. + [Steve Henson] + + *) Change names of new functions to the new get1/get0 naming + convention: After 'get1', the caller owns a reference count + and has to call ..._free; 'get0' returns a pointer to some + data structure without incrementing reference counters. + (Some of the existing 'get' functions increment a reference + counter, some don't.) + Similarly, 'set1' and 'add1' functions increase reference + counters or duplicate objects. + [Steve Henson] + + *) Allow for the possibility of temp RSA key generation failure: + the code used to assume it always worked and crashed on failure. + [Steve Henson] + + *) Fix potential buffer overrun problem in BIO_printf(). + [Ulf Möller, using public domain code by Patrick Powell; problem + pointed out by David Sacerdote ] + + *) Support EGD . New functions + RAND_egd() and RAND_status(). In the command line application, + the EGD socket can be specified like a seed file using RANDFILE + or -rand. + [Ulf Möller] + + *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures. + Some CAs (e.g. Verisign) distribute certificates in this form. + [Steve Henson] + + *) Remove the SSL_ALLOW_ADH compile option and set the default cipher + list to exclude them. This means that no special compilation option + is needed to use anonymous DH: it just needs to be included in the + cipher list. + [Steve Henson] + + *) Change the EVP_MD_CTX_type macro so its meaning consistent with + EVP_MD_type. The old functionality is available in a new macro called + EVP_MD_md(). Change code that uses it and update docs. + [Steve Henson] + + *) ..._ctrl functions now have corresponding ..._callback_ctrl functions + where the 'void *' argument is replaced by a function pointer argument. + Previously 'void *' was abused to point to functions, which works on + many platforms, but is not correct. As these functions are usually + called by macros defined in OpenSSL header files, most source code + should work without changes. + [Richard Levitte] + + *) (which is created by Configure) now contains + sections with information on -D... compiler switches used for + compiling the library so that applications can see them. To enable + one of these sections, a pre-processor symbol OPENSSL_..._DEFINES + must be defined. E.g., + #define OPENSSL_ALGORITHM_DEFINES + #include + defines all pertinent NO_ symbols, such as NO_IDEA, NO_RSA, etc. + [Richard Levitte, Ulf and Bodo Möller] + + *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS + record layer. + [Bodo Moeller] + + *) Change the 'other' type in certificate aux info to a STACK_OF + X509_ALGOR. Although not an AlgorithmIdentifier as such it has + the required ASN1 format: arbitrary types determined by an OID. + [Steve Henson] + + *) Add some PEM_write_X509_REQ_NEW() functions and a command line + argument to 'req'. This is not because the function is newer or + better than others it just uses the work 'NEW' in the certificate + request header lines. Some software needs this. + [Steve Henson] + + *) Reorganise password command line arguments: now passwords can be + obtained from various sources. Delete the PEM_cb function and make + it the default behaviour: i.e. if the callback is NULL and the + usrdata argument is not NULL interpret it as a null terminated pass + phrase. If usrdata and the callback are NULL then the pass phrase + is prompted for as usual. + [Steve Henson] + + *) Add support for the Compaq Atalla crypto accelerator. If it is installed, + the support is automatically enabled. The resulting binaries will + autodetect the card and use it if present. + [Ben Laurie and Compaq Inc.] + + *) Work around for Netscape hang bug. This sends certificate request + and server done in one record. Since this is perfectly legal in the + SSL/TLS protocol it isn't a "bug" option and is on by default. See + the bugs/SSLv3 entry for more info. + [Steve Henson] + + *) HP-UX tune-up: new unified configs, HP C compiler bug workaround. + [Andy Polyakov] + + *) Add -rand argument to smime and pkcs12 applications and read/write + of seed file. + [Steve Henson] + + *) New 'passwd' tool for crypt(3) and apr1 password hashes. + [Bodo Moeller] + + *) Add command line password options to the remaining applications. + [Steve Henson] + + *) Bug fix for BN_div_recp() for numerators with an even number of + bits. + [Ulf Möller] + + *) More tests in bntest.c, and changed test_bn output. + [Ulf Möller] + + *) ./config recognizes MacOS X now. + [Andy Polyakov] + + *) Bug fix for BN_div() when the first words of num and divsor are + equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0). + [Ulf Möller] + + *) Add support for various broken PKCS#8 formats, and command line + options to produce them. + [Steve Henson] + + *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to + get temporary BIGNUMs from a BN_CTX. + [Ulf Möller] + + *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont() + for p == 0. + [Ulf Möller] + + *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and + include a #define from the old name to the new. The original intent + was that statically linked binaries could for example just call + SSLeay_add_all_ciphers() to just add ciphers to the table and not + link with digests. This never worked becayse SSLeay_add_all_digests() + and SSLeay_add_all_ciphers() were in the same source file so calling + one would link with the other. They are now in separate source files. + [Steve Henson] + + *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'. + [Steve Henson] + + *) Use a less unusual form of the Miller-Rabin primality test (it used + a binary algorithm for exponentiation integrated into the Miller-Rabin + loop, our standard modexp algorithms are faster). + [Bodo Moeller] + + *) Support for the EBCDIC character set completed. + [Martin Kraemer ] + + *) Source code cleanups: use const where appropriate, eliminate casts, + use void * instead of char * in lhash. + [Ulf Möller] + + *) Bugfix: ssl3_send_server_key_exchange was not restartable + (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of + this the server could overwrite ephemeral keys that the client + has already seen). + [Bodo Moeller] + + *) Turn DSA_is_prime into a macro that calls BN_is_prime, + using 50 iterations of the Rabin-Miller test. + + DSA_generate_parameters now uses BN_is_prime_fasttest (with 50 + iterations of the Rabin-Miller test as required by the appendix + to FIPS PUB 186[-1]) instead of DSA_is_prime. + As BN_is_prime_fasttest includes trial division, DSA parameter + generation becomes much faster. + + This implies a change for the callback functions in DSA_is_prime + and DSA_generate_parameters: The callback function is called once + for each positive witness in the Rabin-Miller test, not just + occasionally in the inner loop; and the parameters to the + callback function now provide an iteration count for the outer + loop rather than for the current invocation of the inner loop. + DSA_generate_parameters additionally can call the callback + function with an 'iteration count' of -1, meaning that a + candidate has passed the trial division test (when q is generated + from an application-provided seed, trial division is skipped). + [Bodo Moeller] + + *) New function BN_is_prime_fasttest that optionally does trial + division before starting the Rabin-Miller test and has + an additional BN_CTX * argument (whereas BN_is_prime always + has to allocate at least one BN_CTX). + 'callback(1, -1, cb_arg)' is called when a number has passed the + trial division stage. + [Bodo Moeller] + + *) Fix for bug in CRL encoding. The validity dates weren't being handled + as ASN1_TIME. + [Steve Henson] + + *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file. + [Steve Henson] + + *) New function BN_pseudo_rand(). + [Ulf Möller] + + *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable) + bignum version of BN_from_montgomery() with the working code from + SSLeay 0.9.0 (the word based version is faster anyway), and clean up + the comments. + [Ulf Möller] + + *) Avoid a race condition in s2_clnt.c (function get_server_hello) that + made it impossible to use the same SSL_SESSION data structure in + SSL2 clients in multiple threads. + [Bodo Moeller] + + *) The return value of RAND_load_file() no longer counts bytes obtained + by stat(). RAND_load_file(..., -1) is new and uses the complete file + to seed the PRNG (previously an explicit byte count was required). + [Ulf Möller, Bodo Möller] + + *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes + used (char *) instead of (void *) and had casts all over the place. + [Steve Henson] + + *) Make BN_generate_prime() return NULL on error if ret!=NULL. + [Ulf Möller] + + *) Retain source code compatibility for BN_prime_checks macro: + BN_is_prime(..., BN_prime_checks, ...) now uses + BN_prime_checks_for_size to determine the appropriate number of + Rabin-Miller iterations. + [Ulf Möller] + + *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to + DH_CHECK_P_NOT_SAFE_PRIME. + (Check if this is true? OpenPGP calls them "strong".) + [Ulf Möller] + + *) Merge the functionality of "dh" and "gendh" programs into a new program + "dhparam". The old programs are retained for now but will handle DH keys + (instead of parameters) in future. + [Steve Henson] + + *) Make the ciphers, s_server and s_client programs check the return values + when a new cipher list is set. + [Steve Henson] + + *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit + ciphers. Before when the 56bit ciphers were enabled the sorting was + wrong. + + The syntax for the cipher sorting has been extended to support sorting by + cipher-strength (using the strength_bits hard coded in the tables). + The new command is "@STRENGTH" (see also doc/apps/ciphers.pod). + + Fix a bug in the cipher-command parser: when supplying a cipher command + string with an "undefined" symbol (neither command nor alphanumeric + [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now + an error is flagged. + + Due to the strength-sorting extension, the code of the + ssl_create_cipher_list() function was completely rearranged. I hope that + the readability was also increased :-) + [Lutz Jaenicke ] + + *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1 + for the first serial number and places 2 in the serial number file. This + avoids problems when the root CA is created with serial number zero and + the first user certificate has the same issuer name and serial number + as the root CA. + [Steve Henson] + + *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses + the new code. Add documentation for this stuff. + [Steve Henson] + + *) Changes to X509_ATTRIBUTE utilities. These have been renamed from + X509_*() to X509at_*() on the grounds that they don't handle X509 + structures and behave in an analagous way to the X509v3 functions: + they shouldn't be called directly but wrapper functions should be used + instead. + + So we also now have some wrapper functions that call the X509at functions + when passed certificate requests. (TO DO: similar things can be done with + PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other + things. Some of these need some d2i or i2d and print functionality + because they handle more complex structures.) + [Steve Henson] + + *) Add missing #ifndefs that caused missing symbols when building libssl + as a shared library without RSA. Use #ifndef NO_SSL2 instead of + NO_RSA in ssl/s2*.c. + [Kris Kennaway , modified by Ulf Möller] + + *) Precautions against using the PRNG uninitialized: RAND_bytes() now + has a return value which indicates the quality of the random data + (1 = ok, 0 = not seeded). Also an error is recorded on the thread's + error queue. New function RAND_pseudo_bytes() generates output that is + guaranteed to be unique but not unpredictable. RAND_add is like + RAND_seed, but takes an extra argument for an entropy estimate + (RAND_seed always assumes full entropy). + [Ulf Möller] + + *) Do more iterations of Rabin-Miller probable prime test (specifically, + 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes + instead of only 2 for all lengths; see BN_prime_checks_for_size definition + in crypto/bn/bn_prime.c for the complete table). This guarantees a + false-positive rate of at most 2^-80 for random input. + [Bodo Moeller] + + *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs. + [Bodo Moeller] + + *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain + in the 0.9.5 release), this returns the chain + from an X509_CTX structure with a dup of the stack and all + the X509 reference counts upped: so the stack will exist + after X509_CTX_cleanup() has been called. Modify pkcs12.c + to use this. + + Also make SSL_SESSION_print() print out the verify return + code. + [Steve Henson] + + *) Add manpage for the pkcs12 command. Also change the default + behaviour so MAC iteration counts are used unless the new + -nomaciter option is used. This improves file security and + only older versions of MSIE (4.0 for example) need it. + [Steve Henson] + + *) Honor the no-xxx Configure options when creating .DEF files. + [Ulf Möller] + + *) Add PKCS#10 attributes to field table: challengePassword, + unstructuredName and unstructuredAddress. These are taken from + draft PKCS#9 v2.0 but are compatible with v1.2 provided no + international characters are used. + + More changes to X509_ATTRIBUTE code: allow the setting of types + based on strings. Remove the 'loc' parameter when adding + attributes because these will be a SET OF encoding which is sorted + in ASN1 order. + [Steve Henson] + + *) Initial changes to the 'req' utility to allow request generation + automation. This will allow an application to just generate a template + file containing all the field values and have req construct the + request. + + Initial support for X509_ATTRIBUTE handling. Stacks of these are + used all over the place including certificate requests and PKCS#7 + structures. They are currently handled manually where necessary with + some primitive wrappers for PKCS#7. The new functions behave in a + manner analogous to the X509 extension functions: they allow + attributes to be looked up by NID and added. + + Later something similar to the X509V3 code would be desirable to + automatically handle the encoding, decoding and printing of the + more complex types. The string types like challengePassword can + be handled by the string table functions. + + Also modified the multi byte string table handling. Now there is + a 'global mask' which masks out certain types. The table itself + can use the flag STABLE_NO_MASK to ignore the mask setting: this + is useful when for example there is only one permissible type + (as in countryName) and using the mask might result in no valid + types at all. + [Steve Henson] + + *) Clean up 'Finished' handling, and add functions SSL_get_finished and + SSL_get_peer_finished to allow applications to obtain the latest + Finished messages sent to the peer or expected from the peer, + respectively. (SSL_get_peer_finished is usually the Finished message + actually received from the peer, otherwise the protocol will be aborted.) + + As the Finished message are message digests of the complete handshake + (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can + be used for external authentication procedures when the authentication + provided by SSL/TLS is not desired or is not enough. + [Bodo Moeller] + + *) Enhanced support for Alpha Linux is added. Now ./config checks if + the host supports BWX extension and if Compaq C is present on the + $PATH. Just exploiting of the BWX extension results in 20-30% + performance kick for some algorithms, e.g. DES and RC4 to mention + a couple. Compaq C in turn generates ~20% faster code for MD5 and + SHA1. + [Andy Polyakov] + + *) Add support for MS "fast SGC". This is arguably a violation of the + SSL3/TLS protocol. Netscape SGC does two handshakes: the first with + weak crypto and after checking the certificate is SGC a second one + with strong crypto. MS SGC stops the first handshake after receiving + the server certificate message and sends a second client hello. Since + a server will typically do all the time consuming operations before + expecting any further messages from the client (server key exchange + is the most expensive) there is little difference between the two. + + To get OpenSSL to support MS SGC we have to permit a second client + hello message after we have sent server done. In addition we have to + reset the MAC if we do get this second client hello. + [Steve Henson] + + *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide + if a DER encoded private key is RSA or DSA traditional format. Changed + d2i_PrivateKey_bio() to use it. This is only needed for the "traditional" + format DER encoded private key. Newer code should use PKCS#8 format which + has the key type encoded in the ASN1 structure. Added DER private key + support to pkcs8 application. + [Steve Henson] + + *) SSL 3/TLS 1 servers now don't request certificates when an anonymous + ciphersuites has been selected (as required by the SSL 3/TLS 1 + specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT + is set, we interpret this as a request to violate the specification + (the worst that can happen is a handshake failure, and 'correct' + behaviour would result in a handshake failure anyway). + [Bodo Moeller] + + *) In SSL_CTX_add_session, take into account that there might be multiple + SSL_SESSION structures with the same session ID (e.g. when two threads + concurrently obtain them from an external cache). + The internal cache can handle only one SSL_SESSION with a given ID, + so if there's a conflict, we now throw out the old one to achieve + consistency. + [Bodo Moeller] + + *) Add OIDs for idea and blowfish in CBC mode. This will allow both + to be used in PKCS#5 v2.0 and S/MIME. Also add checking to + some routines that use cipher OIDs: some ciphers do not have OIDs + defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for + example. + [Steve Henson] + + *) Simplify the trust setting structure and code. Now we just have + two sequences of OIDs for trusted and rejected settings. These will + typically have values the same as the extended key usage extension + and any application specific purposes. + + The trust checking code now has a default behaviour: it will just + check for an object with the same NID as the passed id. Functions can + be provided to override either the default behaviour or the behaviour + for a given id. SSL client, server and email already have functions + in place for compatibility: they check the NID and also return "trusted" + if the certificate is self signed. + [Steve Henson] + + *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the + traditional format into an EVP_PKEY structure. + [Steve Henson] + + *) Add a password callback function PEM_cb() which either prompts for + a password if usr_data is NULL or otherwise assumes it is a null + terminated password. Allow passwords to be passed on command line + environment or config files in a few more utilities. + [Steve Henson] + + *) Add a bunch of DER and PEM functions to handle PKCS#8 format private + keys. Add some short names for PKCS#8 PBE algorithms and allow them + to be specified on the command line for the pkcs8 and pkcs12 utilities. + Update documentation. + [Steve Henson] + + *) Support for ASN1 "NULL" type. This could be handled before by using + ASN1_TYPE but there wasn't any function that would try to read a NULL + and produce an error if it couldn't. For compatibility we also have + ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and + don't allocate anything because they don't need to. + [Steve Henson] + + *) Initial support for MacOS is now provided. Examine INSTALL.MacOS + for details. + [Andy Polyakov, Roy Woods ] + + *) Rebuild of the memory allocation routines used by OpenSSL code and + possibly others as well. The purpose is to make an interface that + provide hooks so anyone can build a separate set of allocation and + deallocation routines to be used by OpenSSL, for example memory + pool implementations, or something else, which was previously hard + since Malloc(), Realloc() and Free() were defined as macros having + the values malloc, realloc and free, respectively (except for Win32 + compilations). The same is provided for memory debugging code. + OpenSSL already comes with functionality to find memory leaks, but + this gives people a chance to debug other memory problems. + + With these changes, a new set of functions and macros have appeared: + + CRYPTO_set_mem_debug_functions() [F] + CRYPTO_get_mem_debug_functions() [F] + CRYPTO_dbg_set_options() [F] + CRYPTO_dbg_get_options() [F] + CRYPTO_malloc_debug_init() [M] + + The memory debug functions are NULL by default, unless the library + is compiled with CRYPTO_MDEBUG or friends is defined. If someone + wants to debug memory anyway, CRYPTO_malloc_debug_init() (which + gives the standard debugging functions that come with OpenSSL) or + CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions + provided by the library user) must be used. When the standard + debugging functions are used, CRYPTO_dbg_set_options can be used to + request additional information: + CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting + the CRYPTO_MDEBUG_xxx macro when compiling the library. + + Also, things like CRYPTO_set_mem_functions will always give the + expected result (the new set of functions is used for allocation + and deallocation) at all times, regardless of platform and compiler + options. + + To finish it up, some functions that were never use in any other + way than through macros have a new API and new semantic: + + CRYPTO_dbg_malloc() + CRYPTO_dbg_realloc() + CRYPTO_dbg_free() + + All macros of value have retained their old syntax. + [Richard Levitte and Bodo Moeller] + + *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the + ordering of SMIMECapabilities wasn't in "strength order" and there + was a missing NULL in the AlgorithmIdentifier for the SHA1 signature + algorithm. + [Steve Henson] + + *) Some ASN1 types with illegal zero length encoding (INTEGER, + ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines. + [Frans Heymans , modified by Steve Henson] + + *) Merge in my S/MIME library for OpenSSL. This provides a simple + S/MIME API on top of the PKCS#7 code, a MIME parser (with enough + functionality to handle multipart/signed properly) and a utility + called 'smime' to call all this stuff. This is based on code I + originally wrote for Celo who have kindly allowed it to be + included in OpenSSL. + [Steve Henson] + + *) Add variants des_set_key_checked and des_set_key_unchecked of + des_set_key (aka des_key_sched). Global variable des_check_key + decides which of these is called by des_set_key; this way + des_check_key behaves as it always did, but applications and + the library itself, which was buggy for des_check_key == 1, + have a cleaner way to pick the version they need. + [Bodo Moeller] + + *) New function PKCS12_newpass() which changes the password of a + PKCS12 structure. + [Steve Henson] + + *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and + dynamic mix. In both cases the ids can be used as an index into the + table. Also modified the X509_TRUST_add() and X509_PURPOSE_add() + functions so they accept a list of the field values and the + application doesn't need to directly manipulate the X509_TRUST + structure. + [Steve Henson] + + *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't + need initialising. + [Steve Henson] + + *) Modify the way the V3 extension code looks up extensions. This now + works in a similar way to the object code: we have some "standard" + extensions in a static table which is searched with OBJ_bsearch() + and the application can add dynamic ones if needed. The file + crypto/x509v3/ext_dat.h now has the info: this file needs to be + updated whenever a new extension is added to the core code and kept + in ext_nid order. There is a simple program 'tabtest.c' which checks + this. New extensions are not added too often so this file can readily + be maintained manually. + + There are two big advantages in doing things this way. The extensions + can be looked up immediately and no longer need to be "added" using + X509V3_add_standard_extensions(): this function now does nothing. + [Side note: I get *lots* of email saying the extension code doesn't + work because people forget to call this function] + Also no dynamic allocation is done unless new extensions are added: + so if we don't add custom extensions there is no need to call + X509V3_EXT_cleanup(). + [Steve Henson] + + *) Modify enc utility's salting as follows: make salting the default. Add a + magic header, so unsalted files fail gracefully instead of just decrypting + to garbage. This is because not salting is a big security hole, so people + should be discouraged from doing it. + [Ben Laurie] + + *) Fixes and enhancements to the 'x509' utility. It allowed a message + digest to be passed on the command line but it only used this + parameter when signing a certificate. Modified so all relevant + operations are affected by the digest parameter including the + -fingerprint and -x509toreq options. Also -x509toreq choked if a + DSA key was used because it didn't fix the digest. + [Steve Henson] + + *) Initial certificate chain verify code. Currently tests the untrusted + certificates for consistency with the verify purpose (which is set + when the X509_STORE_CTX structure is set up) and checks the pathlength. + + There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour: + this is because it will reject chains with invalid extensions whereas + every previous version of OpenSSL and SSLeay made no checks at all. + + Trust code: checks the root CA for the relevant trust settings. Trust + settings have an initial value consistent with the verify purpose: e.g. + if the verify purpose is for SSL client use it expects the CA to be + trusted for SSL client use. However the default value can be changed to + permit custom trust settings: one example of this would be to only trust + certificates from a specific "secure" set of CAs. + + Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions + which should be used for version portability: especially since the + verify structure is likely to change more often now. + + SSL integration. Add purpose and trust to SSL_CTX and SSL and functions + to set them. If not set then assume SSL clients will verify SSL servers + and vice versa. + + Two new options to the verify program: -untrusted allows a set of + untrusted certificates to be passed in and -purpose which sets the + intended purpose of the certificate. If a purpose is set then the + new chain verify code is used to check extension consistency. + [Steve Henson] + + *) Support for the authority information access extension. + [Steve Henson] + + *) Modify RSA and DSA PEM read routines to transparently handle + PKCS#8 format private keys. New *_PUBKEY_* functions that handle + public keys in a format compatible with certificate + SubjectPublicKeyInfo structures. Unfortunately there were already + functions called *_PublicKey_* which used various odd formats so + these are retained for compatibility: however the DSA variants were + never in a public release so they have been deleted. Changed dsa/rsa + utilities to handle the new format: note no releases ever handled public + keys so we should be OK. + + The primary motivation for this change is to avoid the same fiasco + that dogs private keys: there are several incompatible private key + formats some of which are standard and some OpenSSL specific and + require various evil hacks to allow partial transparent handling and + even then it doesn't work with DER formats. Given the option anything + other than PKCS#8 should be dumped: but the other formats have to + stay in the name of compatibility. + + With public keys and the benefit of hindsight one standard format + is used which works with EVP_PKEY, RSA or DSA structures: though + it clearly returns an error if you try to read the wrong kind of key. + + Added a -pubkey option to the 'x509' utility to output the public key. + Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() + (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add + EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*()) + that do the same as the EVP_PKEY_assign_*() except they up the + reference count of the added key (they don't "swallow" the + supplied key). + [Steve Henson] + + *) Fixes to crypto/x509/by_file.c the code to read in certificates and + CRLs would fail if the file contained no certificates or no CRLs: + added a new function to read in both types and return the number + read: this means that if none are read it will be an error. The + DER versions of the certificate and CRL reader would always fail + because it isn't possible to mix certificates and CRLs in DER format + without choking one or the other routine. Changed this to just read + a certificate: this is the best we can do. Also modified the code + in apps/verify.c to take notice of return codes: it was previously + attempting to read in certificates from NULL pointers and ignoring + any errors: this is one reason why the cert and CRL reader seemed + to work. It doesn't check return codes from the default certificate + routines: these may well fail if the certificates aren't installed. + [Steve Henson] + + *) Code to support otherName option in GeneralName. + [Steve Henson] + + *) First update to verify code. Change the verify utility + so it warns if it is passed a self signed certificate: + for consistency with the normal behaviour. X509_verify + has been modified to it will now verify a self signed + certificate if *exactly* the same certificate appears + in the store: it was previously impossible to trust a + single self signed certificate. This means that: + openssl verify ss.pem + now gives a warning about a self signed certificate but + openssl verify -CAfile ss.pem ss.pem + is OK. + [Steve Henson] + + *) For servers, store verify_result in SSL_SESSION data structure + (and add it to external session representation). + This is needed when client certificate verifications fails, + but an application-provided verification callback (set by + SSL_CTX_set_cert_verify_callback) allows accepting the session + anyway (i.e. leaves x509_store_ctx->error != X509_V_OK + but returns 1): When the session is reused, we have to set + ssl->verify_result to the appropriate error code to avoid + security holes. + [Bodo Moeller, problem pointed out by Lutz Jaenicke] + + *) Fix a bug in the new PKCS#7 code: it didn't consider the + case in PKCS7_dataInit() where the signed PKCS7 structure + didn't contain any existing data because it was being created. + [Po-Cheng Chen , slightly modified by Steve Henson] + + *) Add a salt to the key derivation routines in enc.c. This + forms the first 8 bytes of the encrypted file. Also add a + -S option to allow a salt to be input on the command line. + [Steve Henson] + + *) New function X509_cmp(). Oddly enough there wasn't a function + to compare two certificates. We do this by working out the SHA1 + hash and comparing that. X509_cmp() will be needed by the trust + code. + [Steve Henson] + + *) SSL_get1_session() is like SSL_get_session(), but increments + the reference count in the SSL_SESSION returned. + [Geoff Thorpe ] + + *) Fix for 'req': it was adding a null to request attributes. + Also change the X509_LOOKUP and X509_INFO code to handle + certificate auxiliary information. + [Steve Henson] + + *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document + the 'enc' command. + [Steve Henson] + + *) Add the possibility to add extra information to the memory leak + detecting output, to form tracebacks, showing from where each + allocation was originated: CRYPTO_push_info("constant string") adds + the string plus current file name and line number to a per-thread + stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info() + is like calling CYRPTO_pop_info() until the stack is empty. + Also updated memory leak detection code to be multi-thread-safe. + [Richard Levitte] + + *) Add options -text and -noout to pkcs7 utility and delete the + encryption options which never did anything. Update docs. + [Steve Henson] + + *) Add options to some of the utilities to allow the pass phrase + to be included on either the command line (not recommended on + OSes like Unix) or read from the environment. Update the + manpages and fix a few bugs. + [Steve Henson] + + *) Add a few manpages for some of the openssl commands. + [Steve Henson] + + *) Fix the -revoke option in ca. It was freeing up memory twice, + leaking and not finding already revoked certificates. + [Steve Henson] + + *) Extensive changes to support certificate auxiliary information. + This involves the use of X509_CERT_AUX structure and X509_AUX + functions. An X509_AUX function such as PEM_read_X509_AUX() + can still read in a certificate file in the usual way but it + will also read in any additional "auxiliary information". By + doing things this way a fair degree of compatibility can be + retained: existing certificates can have this information added + using the new 'x509' options. + + Current auxiliary information includes an "alias" and some trust + settings. The trust settings will ultimately be used in enhanced + certificate chain verification routines: currently a certificate + can only be trusted if it is self signed and then it is trusted + for all purposes. + [Steve Henson] + + *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). + The problem was that one of the replacement routines had not been working + since SSLeay releases. For now the offending routine has been replaced + with non-optimised assembler. Even so, this now gives around 95% + performance improvement for 1024 bit RSA signs. + [Mark Cox] + + *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 + handling. Most clients have the effective key size in bits equal to + the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key. + A few however don't do this and instead use the size of the decrypted key + to determine the RC2 key length and the AlgorithmIdentifier to determine + the effective key length. In this case the effective key length can still + be 40 bits but the key length can be 168 bits for example. This is fixed + by manually forcing an RC2 key into the EVP_PKEY structure because the + EVP code can't currently handle unusual RC2 key sizes: it always assumes + the key length and effective key length are equal. + [Steve Henson] + + *) Add a bunch of functions that should simplify the creation of + X509_NAME structures. Now you should be able to do: + X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0); + and have it automatically work out the correct field type and fill in + the structures. The more adventurous can try: + X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0); + and it will (hopefully) work out the correct multibyte encoding. + [Steve Henson] + + *) Change the 'req' utility to use the new field handling and multibyte + copy routines. Before the DN field creation was handled in an ad hoc + way in req, ca, and x509 which was rather broken and didn't support + BMPStrings or UTF8Strings. Since some software doesn't implement + BMPStrings or UTF8Strings yet, they can be enabled using the config file + using the dirstring_type option. See the new comment in the default + openssl.cnf for more info. + [Steve Henson] + + *) Make crypto/rand/md_rand.c more robust: + - Assure unique random numbers after fork(). + - Make sure that concurrent threads access the global counter and + md serializably so that we never lose entropy in them + or use exactly the same state in multiple threads. + Access to the large state is not always serializable because + the additional locking could be a performance killer, and + md should be large enough anyway. + [Bodo Moeller] + + *) New file apps/app_rand.c with commonly needed functionality + for handling the random seed file. + + Use the random seed file in some applications that previously did not: + ca, + dsaparam -genkey (which also ignored its '-rand' option), + s_client, + s_server, + x509 (when signing). + Except on systems with /dev/urandom, it is crucial to have a random + seed file at least for key creation, DSA signing, and for DH exchanges; + for RSA signatures we could do without one. + + gendh and gendsa (unlike genrsa) used to read only the first byte + of each file listed in the '-rand' option. The function as previously + found in genrsa is now in app_rand.c and is used by all programs + that support '-rand'. + [Bodo Moeller] + + *) In RAND_write_file, use mode 0600 for creating files; + don't just chmod when it may be too late. + [Bodo Moeller] + + *) Report an error from X509_STORE_load_locations + when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed. + [Bill Perry] + + *) New function ASN1_mbstring_copy() this copies a string in either + ASCII, Unicode, Universal (4 bytes per character) or UTF8 format + into an ASN1_STRING type. A mask of permissible types is passed + and it chooses the "minimal" type to use or an error if not type + is suitable. + [Steve Henson] + + *) Add function equivalents to the various macros in asn1.h. The old + macros are retained with an M_ prefix. Code inside the library can + use the M_ macros. External code (including the openssl utility) + should *NOT* in order to be "shared library friendly". + [Steve Henson] + + *) Add various functions that can check a certificate's extensions + to see if it usable for various purposes such as SSL client, + server or S/MIME and CAs of these types. This is currently + VERY EXPERIMENTAL but will ultimately be used for certificate chain + verification. Also added a -purpose flag to x509 utility to + print out all the purposes. + [Steve Henson] + + *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated + functions. + [Steve Henson] + + *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search + for, obtain and decode and extension and obtain its critical flag. + This allows all the necessary extension code to be handled in a + single function call. + [Steve Henson] + + *) RC4 tune-up featuring 30-40% performance improvement on most RISC + platforms. See crypto/rc4/rc4_enc.c for further details. + [Andy Polyakov] + + *) New -noout option to asn1parse. This causes no output to be produced + its main use is when combined with -strparse and -out to extract data + from a file (which may not be in ASN.1 format). + [Steve Henson] + + *) Fix for pkcs12 program. It was hashing an invalid certificate pointer + when producing the local key id. + [Richard Levitte ] + + *) New option -dhparam in s_server. This allows a DH parameter file to be + stated explicitly. If it is not stated then it tries the first server + certificate file. The previous behaviour hard coded the filename + "server.pem". + [Steve Henson] + + *) Add -pubin and -pubout options to the rsa and dsa commands. These allow + a public key to be input or output. For example: + openssl rsa -in key.pem -pubout -out pubkey.pem + Also added necessary DSA public key functions to handle this. + [Steve Henson] + + *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained + in the message. This was handled by allowing + X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. + [Steve Henson, reported by Sampo Kellomaki ] + + *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null + to the end of the strings whereas this didn't. This would cause problems + if strings read with d2i_ASN1_bytes() were later modified. + [Steve Henson, reported by Arne Ansper ] + + *) Fix for base64 decode bug. When a base64 bio reads only one line of + data and it contains EOF it will end up returning an error. This is + caused by input 46 bytes long. The cause is due to the way base64 + BIOs find the start of base64 encoded data. They do this by trying a + trial decode on each line until they find one that works. When they + do a flag is set and it starts again knowing it can pass all the + data directly through the decoder. Unfortunately it doesn't reset + the context it uses. This means that if EOF is reached an attempt + is made to pass two EOFs through the context and this causes the + resulting error. This can also cause other problems as well. As is + usual with these problems it takes *ages* to find and the fix is + trivial: move one line. + [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] + + *) Ugly workaround to get s_client and s_server working under Windows. The + old code wouldn't work because it needed to select() on sockets and the + tty (for keypresses and to see if data could be written). Win32 only + supports select() on sockets so we select() with a 1s timeout on the + sockets and then see if any characters are waiting to be read, if none + are present then we retry, we also assume we can always write data to + the tty. This isn't nice because the code then blocks until we've + received a complete line of data and it is effectively polling the + keyboard at 1s intervals: however it's quite a bit better than not + working at all :-) A dedicated Windows application might handle this + with an event loop for example. + [Steve Henson] + + *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign + and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions + will be called when RSA_sign() and RSA_verify() are used. This is useful + if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. + For this to work properly RSA_public_decrypt() and RSA_private_encrypt() + should *not* be used: RSA_sign() and RSA_verify() must be used instead. + This necessitated the support of an extra signature type NID_md5_sha1 + for SSL signatures and modifications to the SSL library to use it instead + of calling RSA_public_decrypt() and RSA_private_encrypt(). + [Steve Henson] + + *) Add new -verify -CAfile and -CApath options to the crl program, these + will lookup a CRL issuers certificate and verify the signature in a + similar way to the verify program. Tidy up the crl program so it + no longer accesses structures directly. Make the ASN1 CRL parsing a bit + less strict. It will now permit CRL extensions even if it is not + a V2 CRL: this will allow it to tolerate some broken CRLs. + [Steve Henson] + + *) Initialize all non-automatic variables each time one of the openssl + sub-programs is started (this is necessary as they may be started + multiple times from the "OpenSSL>" prompt). + [Lennart Bang, Bodo Moeller] + + *) Preliminary compilation option RSA_NULL which disables RSA crypto without + removing all other RSA functionality (this is what NO_RSA does). This + is so (for example) those in the US can disable those operations covered + by the RSA patent while allowing storage and parsing of RSA keys and RSA + key generation. + [Steve Henson] + + *) Non-copying interface to BIO pairs. + (still largely untested) + [Bodo Moeller] + + *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive + ASCII string. This was handled independently in various places before. + [Steve Henson] + + *) New functions UTF8_getc() and UTF8_putc() that parse and generate + UTF8 strings a character at a time. + [Steve Henson] + + *) Use client_version from client hello to select the protocol + (s23_srvr.c) and for RSA client key exchange verification + (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. + [Bodo Moeller] + + *) Add various utility functions to handle SPKACs, these were previously + handled by poking round in the structure internals. Added new function + NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to + print, verify and generate SPKACs. Based on an original idea from + Massimiliano Pala but extensively modified. + [Steve Henson] + + *) RIPEMD160 is operational on all platforms and is back in 'make test'. + [Andy Polyakov] + + *) Allow the config file extension section to be overwritten on the + command line. Based on an original idea from Massimiliano Pala + . The new option is called -extensions + and can be applied to ca, req and x509. Also -reqexts to override + the request extensions in req and -crlexts to override the crl extensions + in ca. + [Steve Henson] + + *) Add new feature to the SPKAC handling in ca. Now you can include + the same field multiple times by preceding it by "XXXX." for example: + 1.OU="Unit name 1" + 2.OU="Unit name 2" + this is the same syntax as used in the req config file. + [Steve Henson] + + *) Allow certificate extensions to be added to certificate requests. These + are specified in a 'req_extensions' option of the req section of the + config file. They can be printed out with the -text option to req but + are otherwise ignored at present. + [Steve Henson] + + *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first + data read consists of only the final block it would not decrypted because + EVP_CipherUpdate() would correctly report zero bytes had been decrypted. + A misplaced 'break' also meant the decrypted final block might not be + copied until the next read. + [Steve Henson] + + *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added + a few extra parameters to the DH structure: these will be useful if + for example we want the value of 'q' or implement X9.42 DH. + [Steve Henson] + + *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and + provides hooks that allow the default DSA functions or functions on a + "per key" basis to be replaced. This allows hardware acceleration and + hardware key storage to be handled without major modification to the + library. Also added low level modexp hooks and CRYPTO_EX structure and + associated functions. + [Steve Henson] + + *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO + as "read only": it can't be written to and the buffer it points to will + not be freed. Reading from a read only BIO is much more efficient than + a normal memory BIO. This was added because there are several times when + an area of memory needs to be read from a BIO. The previous method was + to create a memory BIO and write the data to it, this results in two + copies of the data and an O(n^2) reading algorithm. There is a new + function BIO_new_mem_buf() which creates a read only memory BIO from + an area of memory. Also modified the PKCS#7 routines to use read only + memory BIOs. + [Steve Henson] + + *) Bugfix: ssl23_get_client_hello did not work properly when called in + state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of + a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read, + but a retry condition occured while trying to read the rest. + [Bodo Moeller] + + *) The PKCS7_ENC_CONTENT_new() function was setting the content type as + NID_pkcs7_encrypted by default: this was wrong since this should almost + always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle + the encrypted data type: this is a more sensible place to put it and it + allows the PKCS#12 code to be tidied up that duplicated this + functionality. + [Steve Henson] + + *) Changed obj_dat.pl script so it takes its input and output files on + the command line. This should avoid shell escape redirection problems + under Win32. + [Steve Henson] + + *) Initial support for certificate extension requests, these are included + in things like Xenroll certificate requests. Included functions to allow + extensions to be obtained and added. + [Steve Henson] + + *) -crlf option to s_client and s_server for sending newlines as + CRLF (as required by many protocols). + [Bodo Moeller] + + Changes between 0.9.3a and 0.9.4 [09 Aug 1999] + + *) Install libRSAglue.a when OpenSSL is built with RSAref. + [Ralf S. Engelschall] + + *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. + [Andrija Antonijevic ] + + *) Fix -startdate and -enddate (which was missing) arguments to 'ca' + program. + [Steve Henson] + + *) New function DSA_dup_DH, which duplicates DSA parameters/keys as + DH parameters/keys (q is lost during that conversion, but the resulting + DH parameters contain its length). + + For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is + much faster than DH_generate_parameters (which creates parameters + where p = 2*q + 1), and also the smaller q makes DH computations + much more efficient (160-bit exponentiation instead of 1024-bit + exponentiation); so this provides a convenient way to support DHE + ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of + utter importance to use + SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); + or + SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); + when such DH parameters are used, because otherwise small subgroup + attacks may become possible! + [Bodo Moeller] + + *) Avoid memory leak in i2d_DHparams. + [Bodo Moeller] + + *) Allow the -k option to be used more than once in the enc program: + this allows the same encrypted message to be read by multiple recipients. + [Steve Henson] + + *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts + an ASN1_OBJECT to a text string. If the "no_name" parameter is set then + it will always use the numerical form of the OID, even if it has a short + or long name. + [Steve Henson] + + *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp + method only got called if p,q,dmp1,dmq1,iqmp components were present, + otherwise bn_mod_exp was called. In the case of hardware keys for example + no private key components need be present and it might store extra data + in the RSA structure, which cannot be accessed from bn_mod_exp. + By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for + private key operations. + [Steve Henson] + + *) Added support for SPARC Linux. + [Andy Polyakov] + + *) pem_password_cb function type incompatibly changed from + typedef int pem_password_cb(char *buf, int size, int rwflag); + to + ....(char *buf, int size, int rwflag, void *userdata); + so that applications can pass data to their callbacks: + The PEM[_ASN1]_{read,write}... functions and macros now take an + additional void * argument, which is just handed through whenever + the password callback is called. + [Damien Miller ; tiny changes by Bodo Moeller] + + New function SSL_CTX_set_default_passwd_cb_userdata. + + Compatibility note: As many C implementations push function arguments + onto the stack in reverse order, the new library version is likely to + interoperate with programs that have been compiled with the old + pem_password_cb definition (PEM_whatever takes some data that + happens to be on the stack as its last argument, and the callback + just ignores this garbage); but there is no guarantee whatsoever that + this will work. + + *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... + (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused + problems not only on Windows, but also on some Unix platforms. + To avoid problematic command lines, these definitions are now in an + auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl + for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). + [Bodo Moeller] + + *) MIPS III/IV assembler module is reimplemented. + [Andy Polyakov] + + *) More DES library cleanups: remove references to srand/rand and + delete an unused file. + [Ulf Möller] + + *) Add support for the the free Netwide assembler (NASM) under Win32, + since not many people have MASM (ml) and it can be hard to obtain. + This is currently experimental but it seems to work OK and pass all + the tests. Check out INSTALL.W32 for info. + [Steve Henson] + + *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections + without temporary keys kept an extra copy of the server key, + and connections with temporary keys did not free everything in case + of an error. + [Bodo Moeller] + + *) New function RSA_check_key and new openssl rsa option -check + for verifying the consistency of RSA keys. + [Ulf Moeller, Bodo Moeller] + + *) Various changes to make Win32 compile work: + 1. Casts to avoid "loss of data" warnings in p5_crpt2.c + 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned + comparison" warnings. + 3. Add sk__sort to DEF file generator and do make update. + [Steve Henson] + + *) Add a debugging option to PKCS#5 v2 key generation function: when + you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and + derived keys are printed to stderr. + [Steve Henson] + + *) Copy the flags in ASN1_STRING_dup(). + [Roman E. Pavlov ] + + *) The x509 application mishandled signing requests containing DSA + keys when the signing key was also DSA and the parameters didn't match. + + It was supposed to omit the parameters when they matched the signing key: + the verifying software was then supposed to automatically use the CA's + parameters if they were absent from the end user certificate. + + Omitting parameters is no longer recommended. The test was also + the wrong way round! This was probably due to unusual behaviour in + EVP_cmp_parameters() which returns 1 if the parameters match. + This meant that parameters were omitted when they *didn't* match and + the certificate was useless. Certificates signed with 'ca' didn't have + this bug. + [Steve Henson, reported by Doug Erickson ] + + *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems. + The interface is as follows: + Applications can use + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); + "off" is now the default. + The library internally uses + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() + to disable memory-checking temporarily. + + Some inconsistent states that previously were possible (and were + even the default) are now avoided. + + -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time + with each memory chunk allocated; this is occasionally more helpful + than just having a counter. + + -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID. + + -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future + extensions. + [Bodo Moeller] + + *) Introduce "mode" for SSL structures (with defaults in SSL_CTX), + which largely parallels "options", but is for changing API behaviour, + whereas "options" are about protocol behaviour. + Initial "mode" flags are: + + SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when + a single record has been written. + SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write + retries use the same buffer location. + (But all of the contents must be + copied!) + [Bodo Moeller] + + *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options + worked. + + *) Fix problems with no-hmac etc. + [Ulf Möller, pointed out by Brian Wellington ] + + *) New functions RSA_get_default_method(), RSA_set_method() and + RSA_get_method(). These allows replacement of RSA_METHODs without having + to mess around with the internals of an RSA structure. + [Steve Henson] + + *) Fix memory leaks in DSA_do_sign and DSA_is_prime. + Also really enable memory leak checks in openssl.c and in some + test programs. + [Chad C. Mulligan, Bodo Moeller] + + *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess + up the length of negative integers. This has now been simplified to just + store the length when it is first determined and use it later, rather + than trying to keep track of where data is copied and updating it to + point to the end. + [Steve Henson, reported by Brien Wheeler + ] + + *) Add a new function PKCS7_signatureVerify. This allows the verification + of a PKCS#7 signature but with the signing certificate passed to the + function itself. This contrasts with PKCS7_dataVerify which assumes the + certificate is present in the PKCS#7 structure. This isn't always the + case: certificates can be omitted from a PKCS#7 structure and be + distributed by "out of band" means (such as a certificate database). + [Steve Henson] + + *) Complete the PEM_* macros with DECLARE_PEM versions to replace the + function prototypes in pem.h, also change util/mkdef.pl to add the + necessary function names. + [Steve Henson] + + *) mk1mf.pl (used by Windows builds) did not properly read the + options set by Configure in the top level Makefile, and Configure + was not even able to write more than one option correctly. + Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended. + [Bodo Moeller] + + *) New functions CONF_load_bio() and CONF_load_fp() to allow a config + file to be loaded from a BIO or FILE pointer. The BIO version will + for example allow memory BIOs to contain config info. + [Steve Henson] + + *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS. + Whoever hopes to achieve shared-library compatibility across versions + must use this, not the compile-time macro. + (Exercise 0.9.4: Which is the minimum library version required by + such programs?) + Note: All this applies only to multi-threaded programs, others don't + need locks. + [Bodo Moeller] + + *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests + through a BIO pair triggered the default case, i.e. + SSLerr(...,SSL_R_UNKNOWN_STATE). + [Bodo Moeller] + + *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications + can use the SSL library even if none of the specific BIOs is + appropriate. + [Bodo Moeller] + + *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value + for the encoded length. + [Jeon KyoungHo ] + + *) Add initial documentation of the X509V3 functions. + [Steve Henson] + + *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and + PEM_write_bio_PKCS8PrivateKey() that are equivalent to + PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more + secure PKCS#8 private key format with a high iteration count. + [Steve Henson] + + *) Fix determination of Perl interpreter: A perl or perl5 + _directory_ in $PATH was also accepted as the interpreter. + [Ralf S. Engelschall] + + *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking + wrong with it but it was very old and did things like calling + PEM_ASN1_read() directly and used MD5 for the hash not to mention some + unusual formatting. + [Steve Henson] + + *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed + to use the new extension code. + [Steve Henson] + + *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c + with macros. This should make it easier to change their form, add extra + arguments etc. Fix a few PEM prototypes which didn't have cipher as a + constant. + [Steve Henson] + + *) Add to configuration table a new entry that can specify an alternative + name for unistd.h (for pre-POSIX systems); we need this for NeXTstep, + according to Mark Crispin . + [Bodo Moeller] + +#if 0 + *) DES CBC did not update the IV. Weird. + [Ben Laurie] +#else + des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does. + Changing the behaviour of the former might break existing programs -- + where IV updating is needed, des_ncbc_encrypt can be used. +#endif + + *) When bntest is run from "make test" it drives bc to check its + calculations, as well as internally checking them. If an internal check + fails, it needs to cause bc to give a non-zero result or make test carries + on without noticing the failure. Fixed. + [Ben Laurie] + + *) DES library cleanups. + [Ulf Möller] + + *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be + used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit + ciphers. NOTE: although the key derivation function has been verified + against some published test vectors it has not been extensively tested + yet. Added a -v2 "cipher" option to pkcs8 application to allow the use + of v2.0. + [Steve Henson] + + *) Instead of "mkdir -p", which is not fully portable, use new + Perl script "util/mkdir-p.pl". + [Bodo Moeller] + + *) Rewrite the way password based encryption (PBE) is handled. It used to + assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter + structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms + but doesn't apply to PKCS#5 v2.0 where it can be something else. Now + the 'parameter' field of the AlgorithmIdentifier is passed to the + underlying key generation function so it must do its own ASN1 parsing. + This has also changed the EVP_PBE_CipherInit() function which now has a + 'parameter' argument instead of literal salt and iteration count values + and the function EVP_PBE_ALGOR_CipherInit() has been deleted. + [Steve Henson] + + *) Support for PKCS#5 v1.5 compatible password based encryption algorithms + and PKCS#8 functionality. New 'pkcs8' application linked to openssl. + Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE + KEY" because this clashed with PKCS#8 unencrypted string. Since this + value was just used as a "magic string" and not used directly its + value doesn't matter. + [Steve Henson] + + *) Introduce some semblance of const correctness to BN. Shame C doesn't + support mutable. + [Ben Laurie] + + *) "linux-sparc64" configuration (ultrapenguin). + [Ray Miller ] + "linux-sparc" configuration. + [Christian Forster ] + + *) config now generates no-xxx options for missing ciphers. + [Ulf Möller] + + *) Support the EBCDIC character set (work in progress). + File ebcdic.c not yet included because it has a different license. + [Martin Kraemer ] + + *) Support BS2000/OSD-POSIX. + [Martin Kraemer ] + + *) Make callbacks for key generation use void * instead of char *. + [Ben Laurie] + + *) Make S/MIME samples compile (not yet tested). + [Ben Laurie] + + *) Additional typesafe stacks. + [Ben Laurie] + + *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x). + [Bodo Moeller] + + + Changes between 0.9.3 and 0.9.3a [29 May 1999] + + *) New configuration variant "sco5-gcc". + + *) Updated some demos. + [Sean O Riordain, Wade Scholine] + + *) Add missing BIO_free at exit of pkcs12 application. + [Wu Zhigang] + + *) Fix memory leak in conf.c. + [Steve Henson] + + *) Updates for Win32 to assembler version of MD5. + [Steve Henson] + + *) Set #! path to perl in apps/der_chop to where we found it + instead of using a fixed path. + [Bodo Moeller] + + *) SHA library changes for irix64-mips4-cc. + [Andy Polyakov] + + *) Improvements for VMS support. + [Richard Levitte] + + + Changes between 0.9.2b and 0.9.3 [24 May 1999] + + *) Bignum library bug fix. IRIX 6 passes "make test" now! + This also avoids the problems with SC4.2 and unpatched SC5. + [Andy Polyakov ] + + *) New functions sk_num, sk_value and sk_set to replace the previous macros. + These are required because of the typesafe stack would otherwise break + existing code. If old code used a structure member which used to be STACK + and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with + sk_num or sk_value it would produce an error because the num, data members + are not present in STACK_OF. Now it just produces a warning. sk_set + replaces the old method of assigning a value to sk_value + (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code + that does this will no longer work (and should use sk_set instead) but + this could be regarded as a "questionable" behaviour anyway. + [Steve Henson] + + *) Fix most of the other PKCS#7 bugs. The "experimental" code can now + correctly handle encrypted S/MIME data. + [Steve Henson] + + *) Change type of various DES function arguments from des_cblock + (which means, in function argument declarations, pointer to char) + to des_cblock * (meaning pointer to array with 8 char elements), + which allows the compiler to do more typechecking; it was like + that back in SSLeay, but with lots of ugly casts. + + Introduce new type const_des_cblock. + [Bodo Moeller] + + *) Reorganise the PKCS#7 library and get rid of some of the more obvious + problems: find RecipientInfo structure that matches recipient certificate + and initialise the ASN1 structures properly based on passed cipher. + [Steve Henson] + + *) Belatedly make the BN tests actually check the results. + [Ben Laurie] + + *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion + to and from BNs: it was completely broken. New compilation option + NEG_PUBKEY_BUG to allow for some broken certificates that encode public + key elements as negative integers. + [Steve Henson] + + *) Reorganize and speed up MD5. + [Andy Polyakov ] + + *) VMS support. + [Richard Levitte ] + + *) New option -out to asn1parse to allow the parsed structure to be + output to a file. This is most useful when combined with the -strparse + option to examine the output of things like OCTET STRINGS. + [Steve Henson] + + *) Make SSL library a little more fool-proof by not requiring any longer + that SSL_set_{accept,connect}_state be called before + SSL_{accept,connect} may be used (SSL_set_..._state is omitted + in many applications because usually everything *appeared* to work as + intended anyway -- now it really works as intended). + [Bodo Moeller] + + *) Move openssl.cnf out of lib/. + [Ulf Möller] + + *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall + -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes + -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+ + [Ralf S. Engelschall] + + *) Various fixes to the EVP and PKCS#7 code. It may now be able to + handle PKCS#7 enveloped data properly. + [Sebastian Akerman , modified by Steve] + + *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of + copying pointers. The cert_st handling is changed by this in + various ways (and thus what used to be known as ctx->default_cert + is now called ctx->cert, since we don't resort to s->ctx->[default_]cert + any longer when s->cert does not give us what we need). + ssl_cert_instantiate becomes obsolete by this change. + As soon as we've got the new code right (possibly it already is?), + we have solved a couple of bugs of the earlier code where s->cert + was used as if it could not have been shared with other SSL structures. + + Note that using the SSL API in certain dirty ways now will result + in different behaviour than observed with earlier library versions: + Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx) + does not influence s as it used to. + + In order to clean up things more thoroughly, inside SSL_SESSION + we don't use CERT any longer, but a new structure SESS_CERT + that holds per-session data (if available); currently, this is + the peer's certificate chain and, for clients, the server's certificate + and temporary key. CERT holds only those values that can have + meaningful defaults in an SSL_CTX. + [Bodo Moeller] + + *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure + from the internal representation. Various PKCS#7 fixes: remove some + evil casts and set the enc_dig_alg field properly based on the signing + key type. + [Steve Henson] + + *) Allow PKCS#12 password to be set from the command line or the + environment. Let 'ca' get its config file name from the environment + variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req' + and 'x509'). + [Steve Henson] + + *) Allow certificate policies extension to use an IA5STRING for the + organization field. This is contrary to the PKIX definition but + VeriSign uses it and IE5 only recognises this form. Document 'x509' + extension option. + [Steve Henson] + + *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic, + without disallowing inline assembler and the like for non-pedantic builds. + [Ben Laurie] + + *) Support Borland C++ builder. + [Janez Jere , modified by Ulf Möller] + + *) Support Mingw32. + [Ulf Möller] + + *) SHA-1 cleanups and performance enhancements. + [Andy Polyakov ] + + *) Sparc v8plus assembler for the bignum library. + [Andy Polyakov ] + + *) Accept any -xxx and +xxx compiler options in Configure. + [Ulf Möller] + + *) Update HPUX configuration. + [Anonymous] + + *) Add missing sk__unshift() function to safestack.h + [Ralf S. Engelschall] + + *) New function SSL_CTX_use_certificate_chain_file that sets the + "extra_cert"s in addition to the certificate. (This makes sense + only for "PEM" format files, as chains as a whole are not + DER-encoded.) + [Bodo Moeller] + + *) Support verify_depth from the SSL API. + x509_vfy.c had what can be considered an off-by-one-error: + Its depth (which was not part of the external interface) + was actually counting the number of certificates in a chain; + now it really counts the depth. + [Bodo Moeller] + + *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used + instead of X509err, which often resulted in confusing error + messages since the error codes are not globally unique + (e.g. an alleged error in ssl3_accept when a certificate + didn't match the private key). + + *) New function SSL_CTX_set_session_id_context that allows to set a default + value (so that you don't need SSL_set_session_id_context for each + connection using the SSL_CTX). + [Bodo Moeller] + + *) OAEP decoding bug fix. + [Ulf Möller] + + *) Support INSTALL_PREFIX for package builders, as proposed by + David Harris. + [Bodo Moeller] + + *) New Configure options "threads" and "no-threads". For systems + where the proper compiler options are known (currently Solaris + and Linux), "threads" is the default. + [Bodo Moeller] + + *) New script util/mklink.pl as a faster substitute for util/mklink.sh. + [Bodo Moeller] + + *) Install various scripts to $(OPENSSLDIR)/misc, not to + $(INSTALLTOP)/bin -- they shouldn't clutter directories + such as /usr/local/bin. + [Bodo Moeller] + + *) "make linux-shared" to build shared libraries. + [Niels Poppe ] + + *) New Configure option no- (rsa, idea, rc5, ...). + [Ulf Möller] + + *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for + extension adding in x509 utility. + [Steve Henson] + + *) Remove NOPROTO sections and error code comments. + [Ulf Möller] + + *) Partial rewrite of the DEF file generator to now parse the ANSI + prototypes. + [Steve Henson] + + *) New Configure options --prefix=DIR and --openssldir=DIR. + [Ulf Möller] + + *) Complete rewrite of the error code script(s). It is all now handled + by one script at the top level which handles error code gathering, + header rewriting and C source file generation. It should be much better + than the old method: it now uses a modified version of Ulf's parser to + read the ANSI prototypes in all header files (thus the old K&R definitions + aren't needed for error creation any more) and do a better job of + translating function codes into names. The old 'ASN1 error code imbedded + in a comment' is no longer necessary and it doesn't use .err files which + have now been deleted. Also the error code call doesn't have to appear all + on one line (which resulted in some large lines...). + [Steve Henson] + + *) Change #include filenames from to . + [Bodo Moeller] + + *) Change behaviour of ssl2_read when facing length-0 packets: Don't return + 0 (which usually indicates a closed connection), but continue reading. + [Bodo Moeller] + + *) Fix some race conditions. + [Bodo Moeller] + + *) Add support for CRL distribution points extension. Add Certificate + Policies and CRL distribution points documentation. + [Steve Henson] + + *) Move the autogenerated header file parts to crypto/opensslconf.h. + [Ulf Möller] + + *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of + 8 of keying material. Merlin has also confirmed interop with this fix + between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0. + [Merlin Hughes ] + + *) Fix lots of warnings. + [Richard Levitte ] + + *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if + the directory spec didn't end with a LIST_SEPARATOR_CHAR. + [Richard Levitte ] + + *) Fix problems with sizeof(long) == 8. + [Andy Polyakov ] + + *) Change functions to ANSI C. + [Ulf Möller] + + *) Fix typos in error codes. + [Martin Kraemer , Ulf Möller] + + *) Remove defunct assembler files from Configure. + [Ulf Möller] + + *) SPARC v8 assembler BIGNUM implementation. + [Andy Polyakov ] + + *) Support for Certificate Policies extension: both print and set. + Various additions to support the r2i method this uses. + [Steve Henson] + + *) A lot of constification, and fix a bug in X509_NAME_oneline() that could + return a const string when you are expecting an allocated buffer. + [Ben Laurie] + + *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE + types DirectoryString and DisplayText. + [Steve Henson] + + *) Add code to allow r2i extensions to access the configuration database, + add an LHASH database driver and add several ctx helper functions. + [Steve Henson] + + *) Fix an evil bug in bn_expand2() which caused various BN functions to + fail when they extended the size of a BIGNUM. + [Steve Henson] + + *) Various utility functions to handle SXNet extension. Modify mkdef.pl to + support typesafe stack. + [Steve Henson] + + *) Fix typo in SSL_[gs]et_options(). + [Nils Frostberg ] + + *) Delete various functions and files that belonged to the (now obsolete) + old X509V3 handling code. + [Steve Henson] + + *) New Configure option "rsaref". + [Ulf Möller] + + *) Don't auto-generate pem.h. + [Bodo Moeller] + + *) Introduce type-safe ASN.1 SETs. + [Ben Laurie] + + *) Convert various additional casted stacks to type-safe STACK_OF() variants. + [Ben Laurie, Ralf S. Engelschall, Steve Henson] + + *) Introduce type-safe STACKs. This will almost certainly break lots of code + that links with OpenSSL (well at least cause lots of warnings), but fear + not: the conversion is trivial, and it eliminates loads of evil casts. A + few STACKed things have been converted already. Feel free to convert more. + In the fullness of time, I'll do away with the STACK type altogether. + [Ben Laurie] + + *) Add `openssl ca -revoke ' facility which revokes a certificate + specified in by updating the entry in the index.txt file. + This way one no longer has to edit the index.txt file manually for + revoking a certificate. The -revoke option does the gory details now. + [Massimiliano Pala , Ralf S. Engelschall] + + *) Fix `openssl crl -noout -text' combination where `-noout' killed the + `-text' option at all and this way the `-noout -text' combination was + inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'. + [Ralf S. Engelschall] + + *) Make sure a corresponding plain text error message exists for the + X509_V_ERR_CERT_REVOKED/23 error number which can occur when a + verify callback function determined that a certificate was revoked. + [Ralf S. Engelschall] + + *) Bugfix: In test/testenc, don't test "openssl " for + ciphers that were excluded, e.g. by -DNO_IDEA. Also, test + all available cipers including rc5, which was forgotten until now. + In order to let the testing shell script know which algorithms + are available, a new (up to now undocumented) command + "openssl list-cipher-commands" is used. + [Bodo Moeller] + + *) Bugfix: s_client occasionally would sleep in select() when + it should have checked SSL_pending() first. + [Bodo Moeller] + + *) New functions DSA_do_sign and DSA_do_verify to provide access to + the raw DSA values prior to ASN.1 encoding. + [Ulf Möller] + + *) Tweaks to Configure + [Niels Poppe ] + + *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support, + yet... + [Steve Henson] + + *) New variables $(RANLIB) and $(PERL) in the Makefiles. + [Ulf Möller] + + *) New config option to avoid instructions that are illegal on the 80386. + The default code is faster, but requires at least a 486. + [Ulf Möller] + + *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and + SSL2_SERVER_VERSION (not used at all) macros, which are now the + same as SSL2_VERSION anyway. + [Bodo Moeller] + + *) New "-showcerts" option for s_client. + [Bodo Moeller] + + *) Still more PKCS#12 integration. Add pkcs12 application to openssl + application. Various cleanups and fixes. + [Steve Henson] + + *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and + modify error routines to work internally. Add error codes and PBE init + to library startup routines. + [Steve Henson] + + *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and + packing functions to asn1 and evp. Changed function names and error + codes along the way. + [Steve Henson] + + *) PKCS12 integration: and so it begins... First of several patches to + slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12 + objects to objects.h + [Steve Henson] + + *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1 + and display support for Thawte strong extranet extension. + [Steve Henson] + + *) Add LinuxPPC support. + [Jeff Dubrule ] + + *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to + bn_div_words in alpha.s. + [Hannes Reinecke and Ben Laurie] + + *) Make sure the RSA OAEP test is skipped under -DRSAref because + OAEP isn't supported when OpenSSL is built with RSAref. + [Ulf Moeller ] + + *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h + so they no longer are missing under -DNOPROTO. + [Soren S. Jorvang ] + + + Changes between 0.9.1c and 0.9.2b [22 Mar 1999] + + *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still + doesn't work when the session is reused. Coming soon! + [Ben Laurie] + + *) Fix a security hole, that allows sessions to be reused in the wrong + context thus bypassing client cert protection! All software that uses + client certs and session caches in multiple contexts NEEDS PATCHING to + allow session reuse! A fuller solution is in the works. + [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)] + + *) Some more source tree cleanups (removed obsolete files + crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed + permission on "config" script to be executable) and a fix for the INSTALL + document. + [Ulf Moeller ] + + *) Remove some legacy and erroneous uses of malloc, free instead of + Malloc, Free. + [Lennart Bang , with minor changes by Steve] + + *) Make rsa_oaep_test return non-zero on error. + [Ulf Moeller ] + + *) Add support for native Solaris shared libraries. Configure + solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice + if someone would make that last step automatic. + [Matthias Loepfe ] + + *) ctx_size was not built with the right compiler during "make links". Fixed. + [Ben Laurie] + + *) Change the meaning of 'ALL' in the cipher list. It now means "everything + except NULL ciphers". This means the default cipher list will no longer + enable NULL ciphers. They need to be specifically enabled e.g. with + the string "DEFAULT:eNULL". + [Steve Henson] + + *) Fix to RSA private encryption routines: if p < q then it would + occasionally produce an invalid result. This will only happen with + externally generated keys because OpenSSL (and SSLeay) ensure p > q. + [Steve Henson] + + *) Be less restrictive and allow also `perl util/perlpath.pl + /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin', + because this way one can also use an interpreter named `perl5' (which is + usually the name of Perl 5.xxx on platforms where an Perl 4.x is still + installed as `perl'). + [Matthias Loepfe ] + + *) Let util/clean-depend.pl work also with older Perl 5.00x versions. + [Matthias Loepfe ] + + *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add + advapi32.lib to Win32 build and change the pem test comparision + to fc.exe (thanks to Ulrich Kroener for the + suggestion). Fix misplaced ASNI prototypes and declarations in evp.h + and crypto/des/ede_cbcm_enc.c. + [Steve Henson] + + *) DES quad checksum was broken on big-endian architectures. Fixed. + [Ben Laurie] + + *) Comment out two functions in bio.h that aren't implemented. Fix up the + Win32 test batch file so it (might) work again. The Win32 test batch file + is horrible: I feel ill.... + [Steve Henson] + + *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected + in e_os.h. Audit of header files to check ANSI and non ANSI + sections: 10 functions were absent from non ANSI section and not exported + from Windows DLLs. Fixed up libeay.num for new functions. + [Steve Henson] + + *) Make `openssl version' output lines consistent. + [Ralf S. Engelschall] + + *) Fix Win32 symbol export lists for BIO functions: Added + BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data + to ms/libeay{16,32}.def. + [Ralf S. Engelschall] + + *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled + fine under Unix and passes some trivial tests I've now added. But the + whole stuff is horribly incomplete, so a README.1ST with a disclaimer was + added to make sure no one expects that this stuff really works in the + OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources + up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and + openssl_bio.xs. + [Ralf S. Engelschall] + + *) Fix the generation of two part addresses in perl. + [Kenji Miyake , integrated by Ben Laurie] + + *) Add config entry for Linux on MIPS. + [John Tobey ] + + *) Make links whenever Configure is run, unless we are on Windoze. + [Ben Laurie] + + *) Permit extensions to be added to CRLs using crl_section in openssl.cnf. + Currently only issuerAltName and AuthorityKeyIdentifier make any sense + in CRLs. + [Steve Henson] + + *) Add a useful kludge to allow package maintainers to specify compiler and + other platforms details on the command line without having to patch the + Configure script everytime: One now can use ``perl Configure + :
'', i.e. platform ids are allowed to have details appended + to them (seperated by colons). This is treated as there would be a static + pre-configured entry in Configure's %table under key with value +
and ``perl Configure '' is called. So, when you want to + perform a quick test-compile under FreeBSD 3.1 with pgcc and without + assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"'' + now, which overrides the FreeBSD-elf entry on-the-fly. + [Ralf S. Engelschall] + + *) Disable new TLS1 ciphersuites by default: they aren't official yet. + [Ben Laurie] + + *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified + on the `perl Configure ...' command line. This way one can compile + OpenSSL libraries with Position Independent Code (PIC) which is needed + for linking it into DSOs. + [Ralf S. Engelschall] + + *) Remarkably, export ciphers were totally broken and no-one had noticed! + Fixed. + [Ben Laurie] + + *) Cleaned up the LICENSE document: The official contact for any license + questions now is the OpenSSL core team under openssl-core@openssl.org. + And add a paragraph about the dual-license situation to make sure people + recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply + to the OpenSSL toolkit. + [Ralf S. Engelschall] + + *) General source tree makefile cleanups: Made `making xxx in yyy...' + display consistent in the source tree and replaced `/bin/rm' by `rm'. + Additonally cleaned up the `make links' target: Remove unnecessary + semicolons, subsequent redundant removes, inline point.sh into mklink.sh + to speed processing and no longer clutter the display with confusing + stuff. Instead only the actually done links are displayed. + [Ralf S. Engelschall] + + *) Permit null encryption ciphersuites, used for authentication only. It used + to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this. + It is now necessary to set SSL_FORBID_ENULL to prevent the use of null + encryption. + [Ben Laurie] + + *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder + signed attributes when verifying signatures (this would break them), + the detached data encoding was wrong and public keys obtained using + X509_get_pubkey() weren't freed. + [Steve Henson] + + *) Add text documentation for the BUFFER functions. Also added a work around + to a Win95 console bug. This was triggered by the password read stuff: the + last character typed gets carried over to the next fread(). If you were + generating a new cert request using 'req' for example then the last + character of the passphrase would be CR which would then enter the first + field as blank. + [Steve Henson] + + *) Added the new `Includes OpenSSL Cryptography Software' button as + doc/openssl_button.{gif,html} which is similar in style to the old SSLeay + button and can be used by applications based on OpenSSL to show the + relationship to the OpenSSL project. + [Ralf S. Engelschall] + + *) Remove confusing variables in function signatures in files + ssl/ssl_lib.c and ssl/ssl.h. + [Lennart Bong ] + + *) Don't install bss_file.c under PREFIX/include/ + [Lennart Bong ] + + *) Get the Win32 compile working again. Modify mkdef.pl so it can handle + functions that return function pointers and has support for NT specific + stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various + #ifdef WIN32 and WINNTs sprinkled about the place and some changes from + unsigned to signed types: this was killing the Win32 compile. + [Steve Henson] + + *) Add new certificate file to stack functions, + SSL_add_dir_cert_subjects_to_stack() and + SSL_add_file_cert_subjects_to_stack(). These largely supplant + SSL_load_client_CA_file(), and can be used to add multiple certs easily + to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()). + This means that Apache-SSL and similar packages don't have to mess around + to add as many CAs as they want to the preferred list. + [Ben Laurie] + + *) Experiment with doxygen documentation. Currently only partially applied to + ssl/ssl_lib.c. + See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with + openssl.doxy as the configuration file. + [Ben Laurie] + + *) Get rid of remaining C++-style comments which strict C compilers hate. + [Ralf S. Engelschall, pointed out by Carlos Amengual] + + *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not + compiled in by default: it has problems with large keys. + [Steve Henson] + + *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and + DH private keys and/or callback functions which directly correspond to + their SSL_CTX_xxx() counterparts but work on a per-connection basis. This + is needed for applications which have to configure certificates on a + per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis + (e.g. s_server). + For the RSA certificate situation is makes no difference, but + for the DSA certificate situation this fixes the "no shared cipher" + problem where the OpenSSL cipher selection procedure failed because the + temporary keys were not overtaken from the context and the API provided + no way to reconfigure them. + The new functions now let applications reconfigure the stuff and they + are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, + SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new + non-public-API function ssl_cert_instantiate() is used as a helper + function and also to reduce code redundancy inside ssl_rsa.c. + [Ralf S. Engelschall] + + *) Move s_server -dcert and -dkey options out of the undocumented feature + area because they are useful for the DSA situation and should be + recognized by the users. + [Ralf S. Engelschall] + + *) Fix the cipher decision scheme for export ciphers: the export bits are + *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within + SSL_EXP_MASK. So, the original variable has to be used instead of the + already masked variable. + [Richard Levitte ] + + *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c + [Richard Levitte ] + + *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() + from `int' to `unsigned int' because it's a length and initialized by + EVP_DigestFinal() which expects an `unsigned int *'. + [Richard Levitte ] + + *) Don't hard-code path to Perl interpreter on shebang line of Configure + script. Instead use the usual Shell->Perl transition trick. + [Ralf S. Engelschall] + + *) Make `openssl x509 -noout -modulus' functional also for DSA certificates + (in addition to RSA certificates) to match the behaviour of `openssl dsa + -noout -modulus' as it's already the case for `openssl rsa -noout + -modulus'. For RSA the -modulus is the real "modulus" while for DSA + currently the public key is printed (a decision which was already done by + `openssl dsa -modulus' in the past) which serves a similar purpose. + Additionally the NO_RSA no longer completely removes the whole -modulus + option; it now only avoids using the RSA stuff. Same applies to NO_DSA + now, too. + [Ralf S. Engelschall] + + *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested + BIO. See the source (crypto/evp/bio_ok.c) for more info. + [Arne Ansper ] + + *) Dump the old yucky req code that tried (and failed) to allow raw OIDs + to be added. Now both 'req' and 'ca' can use new objects defined in the + config file. + [Steve Henson] + + *) Add cool BIO that does syslog (or event log on NT). + [Arne Ansper , integrated by Ben Laurie] + + *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, + TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and + TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher + Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt. + [Ben Laurie] + + *) Add preliminary config info for new extension code. + [Steve Henson] + + *) Make RSA_NO_PADDING really use no padding. + [Ulf Moeller ] + + *) Generate errors when private/public key check is done. + [Ben Laurie] + + *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support + for some CRL extensions and new objects added. + [Steve Henson] + + *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private + key usage extension and fuller support for authority key id. + [Steve Henson] + + *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved + padding method for RSA, which is recommended for new applications in PKCS + #1 v2.0 (RFC 2437, October 1998). + OAEP (Optimal Asymmetric Encryption Padding) has better theoretical + foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure + against Bleichbacher's attack on RSA. + [Ulf Moeller , reformatted, corrected and integrated by + Ben Laurie] + + *) Updates to the new SSL compression code + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Fix so that the version number in the master secret, when passed + via RSA, checks that if TLS was proposed, but we roll back to SSLv3 + (because the server will not accept higher), that the version number + is 0x03,0x01, not 0x03,0x00 + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory + leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes + in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c + [Steve Henson] + + *) Support for RAW extensions where an arbitrary extension can be + created by including its DER encoding. See apps/openssl.cnf for + an example. + [Steve Henson] + + *) Make sure latest Perl versions don't interpret some generated C array + code as Perl array code in the crypto/err/err_genc.pl script. + [Lars Weber <3weber@informatik.uni-hamburg.de>] + + *) Modify ms/do_ms.bat to not generate assembly language makefiles since + not many people have the assembler. Various Win32 compilation fixes and + update to the INSTALL.W32 file with (hopefully) more accurate Win32 + build instructions. + [Steve Henson] + + *) Modify configure script 'Configure' to automatically create crypto/date.h + file under Win32 and also build pem.h from pem.org. New script + util/mkfiles.pl to create the MINFO file on environments that can't do a + 'make files': perl util/mkfiles.pl >MINFO should work. + [Steve Henson] + + *) Major rework of DES function declarations, in the pursuit of correctness + and purity. As a result, many evil casts evaporated, and some weirdness, + too. You may find this causes warnings in your code. Zapping your evil + casts will probably fix them. Mostly. + [Ben Laurie] + + *) Fix for a typo in asn1.h. Bug fix to object creation script + obj_dat.pl. It considered a zero in an object definition to mean + "end of object": none of the objects in objects.h have any zeros + so it wasn't spotted. + [Steve Henson, reported by Erwann ABALEA ] + + *) Add support for Triple DES Cipher Block Chaining with Output Feedback + Masking (CBCM). In the absence of test vectors, the best I have been able + to do is check that the decrypt undoes the encrypt, so far. Send me test + vectors if you have them. + [Ben Laurie] + + *) Correct calculation of key length for export ciphers (too much space was + allocated for null ciphers). This has not been tested! + [Ben Laurie] + + *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage + message is now correct (it understands "crypto" and "ssl" on its + command line). There is also now an "update" option. This will update + the util/ssleay.num and util/libeay.num files with any new functions. + If you do a: + perl util/mkdef.pl crypto ssl update + it will update them. + [Steve Henson] + + *) Overhauled the Perl interface (perl/*): + - ported BN stuff to OpenSSL's different BN library + - made the perl/ source tree CVS-aware + - renamed the package from SSLeay to OpenSSL (the files still contain + their history because I've copied them in the repository) + - removed obsolete files (the test scripts will be replaced + by better Test::Harness variants in the future) + [Ralf S. Engelschall] + + *) First cut for a very conservative source tree cleanup: + 1. merge various obsolete readme texts into doc/ssleay.txt + where we collect the old documents and readme texts. + 2. remove the first part of files where I'm already sure that we no + longer need them because of three reasons: either they are just temporary + files which were left by Eric or they are preserved original files where + I've verified that the diff is also available in the CVS via "cvs diff + -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for + the crypto/md/ stuff). + [Ralf S. Engelschall] + + *) More extension code. Incomplete support for subject and issuer alt + name, issuer and authority key id. Change the i2v function parameters + and add an extra 'crl' parameter in the X509V3_CTX structure: guess + what that's for :-) Fix to ASN1 macro which messed up + IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED. + [Steve Henson] + + *) Preliminary support for ENUMERATED type. This is largely copied from the + INTEGER code. + [Steve Henson] + + *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy. + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Make sure `make rehash' target really finds the `openssl' program. + [Ralf S. Engelschall, Matthias Loepfe ] + + *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd + like to hear about it if this slows down other processors. + [Ben Laurie] + + *) Add CygWin32 platform information to Configure script. + [Alan Batie ] + + *) Fixed ms/32all.bat script: `no_asm' -> `no-asm' + [Rainer W. Gerling ] + + *) New program nseq to manipulate netscape certificate sequences + [Steve Henson] + + *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a + few typos. + [Steve Henson] + + *) Fixes to BN code. Previously the default was to define BN_RECURSION + but the BN code had some problems that would cause failures when + doing certificate verification and some other functions. + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Add ASN1 and PEM code to support netscape certificate sequences. + [Steve Henson] + + *) Add ASN1 and PEM code to support netscape certificate sequences. + [Steve Henson] + + *) Add several PKIX and private extended key usage OIDs. + [Steve Henson] + + *) Modify the 'ca' program to handle the new extension code. Modify + openssl.cnf for new extension format, add comments. + [Steve Henson] + + *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' + and add a sample to openssl.cnf so req -x509 now adds appropriate + CA extensions. + [Steve Henson] + + *) Continued X509 V3 changes. Add to other makefiles, integrate with the + error code, add initial support to X509_print() and x509 application. + [Steve Henson] + + *) Takes a deep breath and start addding X509 V3 extension support code. Add + files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this + stuff is currently isolated and isn't even compiled yet. + [Steve Henson] + + *) Continuing patches for GeneralizedTime. Fix up certificate and CRL + ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. + Removed the versions check from X509 routines when loading extensions: + this allows certain broken certificates that don't set the version + properly to be processed. + [Steve Henson] + + *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another + Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which + can still be regenerated with "make depend". + [Ben Laurie] + + *) Spelling mistake in C version of CAST-128. + [Ben Laurie, reported by Jeremy Hylton ] + + *) Changes to the error generation code. The perl script err-code.pl + now reads in the old error codes and retains the old numbers, only + adding new ones if necessary. It also only changes the .err files if new + codes are added. The makefiles have been modified to only insert errors + when needed (to avoid needlessly modifying header files). This is done + by only inserting errors if the .err file is newer than the auto generated + C file. To rebuild all the error codes from scratch (the old behaviour) + either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl + or delete all the .err files. + [Steve Henson] + + *) CAST-128 was incorrectly implemented for short keys. The C version has + been fixed, but is untested. The assembler versions are also fixed, but + new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing + to regenerate it if needed. + [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun + Hagino ] + + *) File was opened incorrectly in randfile.c. + [Ulf Möller ] + + *) Beginning of support for GeneralizedTime. d2i, i2d, check and print + functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or + GeneralizedTime. ASN1_TIME is the proper type used in certificates et + al: it's just almost always a UTCTime. Note this patch adds new error + codes so do a "make errors" if there are problems. + [Steve Henson] + + *) Correct Linux 1 recognition in config. + [Ulf Möller ] + + *) Remove pointless MD5 hash when using DSA keys in ca. + [Anonymous ] + + *) Generate an error if given an empty string as a cert directory. Also + generate an error if handed NULL (previously returned 0 to indicate an + error, but didn't set one). + [Ben Laurie, reported by Anonymous ] + + *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last. + [Ben Laurie] + + *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct + parameters. This was causing a warning which killed off the Win32 compile. + [Steve Henson] + + *) Remove C++ style comments from crypto/bn/bn_local.h. + [Neil Costigan ] + + *) The function OBJ_txt2nid was broken. It was supposed to return a nid + based on a text string, looking up short and long names and finally + "dot" format. The "dot" format stuff didn't work. Added new function + OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote + OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the + OID is not part of the table. + [Steve Henson] + + *) Add prototypes to X509 lookup/verify methods, fixing a bug in + X509_LOOKUP_by_alias(). + [Ben Laurie] + + *) Sort openssl functions by name. + [Ben Laurie] + + *) Get the gendsa program working (hopefully) and add it to app list. Remove + encryption from sample DSA keys (in case anyone is interested the password + was "1234"). + [Steve Henson] + + *) Make _all_ *_free functions accept a NULL pointer. + [Frans Heymans ] + + *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use + NULL pointers. + [Anonymous ] + + *) s_server should send the CAfile as acceptable CAs, not its own cert. + [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] + + *) Don't blow it for numeric -newkey arguments to apps/req. + [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] + + *) Temp key "for export" tests were wrong in s3_srvr.c. + [Anonymous ] + + *) Add prototype for temp key callback functions + SSL_CTX_set_tmp_{rsa,dh}_callback(). + [Ben Laurie] + + *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and + DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey(). + [Steve Henson] + + *) X509_name_add_entry() freed the wrong thing after an error. + [Arne Ansper ] + + *) rsa_eay.c would attempt to free a NULL context. + [Arne Ansper ] + + *) BIO_s_socket() had a broken should_retry() on Windoze. + [Arne Ansper ] + + *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH. + [Arne Ansper ] + + *) Make sure the already existing X509_STORE->depth variable is initialized + in X509_STORE_new(), but document the fact that this variable is still + unused in the certificate verification process. + [Ralf S. Engelschall] + + *) Fix the various library and apps files to free up pkeys obtained from + X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions. + [Steve Henson] + + *) Fix reference counting in X509_PUBKEY_get(). This makes + demos/maurice/example2.c work, amongst others, probably. + [Steve Henson and Ben Laurie] + + *) First cut of a cleanup for apps/. First the `ssleay' program is now named + `openssl' and second, the shortcut symlinks for the `openssl ' + are no longer created. This way we have a single and consistent command + line interface `openssl ', similar to `cvs '. + [Ralf S. Engelschall, Paul Sutton and Ben Laurie] + + *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey + BIT STRING wrapper always have zero unused bits. + [Steve Henson] + + *) Add CA.pl, perl version of CA.sh, add extended key usage OID. + [Steve Henson] + + *) Make the top-level INSTALL documentation easier to understand. + [Paul Sutton] + + *) Makefiles updated to exit if an error occurs in a sub-directory + make (including if user presses ^C) [Paul Sutton] + + *) Make Montgomery context stuff explicit in RSA data structure. + [Ben Laurie] + + *) Fix build order of pem and err to allow for generated pem.h. + [Ben Laurie] + + *) Fix renumbering bug in X509_NAME_delete_entry(). + [Ben Laurie] + + *) Enhanced the err-ins.pl script so it makes the error library number + global and can add a library name. This is needed for external ASN1 and + other error libraries. + [Steve Henson] + + *) Fixed sk_insert which never worked properly. + [Steve Henson] + + *) Fix ASN1 macros so they can handle indefinite length construted + EXPLICIT tags. Some non standard certificates use these: they can now + be read in. + [Steve Henson] + + *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc) + into a single doc/ssleay.txt bundle. This way the information is still + preserved but no longer messes up this directory. Now it's new room for + the new set of documenation files. + [Ralf S. Engelschall] + + *) SETs were incorrectly DER encoded. This was a major pain, because they + shared code with SEQUENCEs, which aren't coded the same. This means that + almost everything to do with SETs or SEQUENCEs has either changed name or + number of arguments. + [Ben Laurie, based on a partial fix by GP Jayan ] + + *) Fix test data to work with the above. + [Ben Laurie] + + *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but + was already fixed by Eric for 0.9.1 it seems. + [Ben Laurie - pointed out by Ulf Möller ] + + *) Autodetect FreeBSD3. + [Ben Laurie] + + *) Fix various bugs in Configure. This affects the following platforms: + nextstep + ncr-scde + unixware-2.0 + unixware-2.0-pentium + sco5-cc. + [Ben Laurie] + + *) Eliminate generated files from CVS. Reorder tests to regenerate files + before they are needed. + [Ben Laurie] + + *) Generate Makefile.ssl from Makefile.org (to keep CVS happy). + [Ben Laurie] + + + Changes between 0.9.1b and 0.9.1c [23-Dec-1998] + + *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and + changed SSLeay to OpenSSL in version strings. + [Ralf S. Engelschall] + + *) Some fixups to the top-level documents. + [Paul Sutton] + + *) Fixed the nasty bug where rsaref.h was not found under compile-time + because the symlink to include/ was missing. + [Ralf S. Engelschall] + + *) Incorporated the popular no-RSA/DSA-only patches + which allow to compile a RSA-free SSLeay. + [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall] + + *) Fixed nasty rehash problem under `make -f Makefile.ssl links' + when "ssleay" is still not found. + [Ralf S. Engelschall] + + *) Added more platforms to Configure: Cray T3E, HPUX 11, + [Ralf S. Engelschall, Beckmann ] + + *) Updated the README file. + [Ralf S. Engelschall] + + *) Added various .cvsignore files in the CVS repository subdirs + to make a "cvs update" really silent. + [Ralf S. Engelschall] + + *) Recompiled the error-definition header files and added + missing symbols to the Win32 linker tables. + [Ralf S. Engelschall] + + *) Cleaned up the top-level documents; + o new files: CHANGES and LICENSE + o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay + o merged COPYRIGHT into LICENSE + o removed obsolete TODO file + o renamed MICROSOFT to INSTALL.W32 + [Ralf S.

Hudson created while they were working for C2Net until + summer 1998. + [The OpenSSL Project] + + + Changes between 0.9.0b and 0.9.1b [not released] + + *) Updated a few CA certificates under certs/ + [Eric A.

Young] + + *) New COMP library [crypto/comp/] for SSL Record Layer Compression: + RLE (dummy implemented) and ZLIB (really implemented when ZLIB is + available). + [Eric A. Young] + + *) Add -strparse option to asn1pars program which parses nested + binary structures + [Dr Stephen Henson ] + + *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs. + [Eric A.

This lets + applications get notified on creation and destruction. Some of + the RSA methods could be implemented this way and I may do so. + - Oh yes, SSL under perl5 is working at the basic level. + +15-Dec-97 + - Warning - the gethostbyname cache is not fully thread safe, + but it should work well enough. + - Major internal reworking of the app_data stuff. More functions + but if you were accessing ->app_data directly, things will + stop working. + - The perlv5 stuff is working. Currently on message digests, + ciphers and the bignum library. + +9-Dec-97 + - Modified re-negotiation so that server initated re-neg + will cause a SSL_read() to return -1 should retry. + The danger otherwise was that the server and the + client could end up both trying to read when using non-blocking + sockets. + +4-Dec-97 + - Lots of small changes + - Fix for binaray mode in Windows for the FILE BIO, thanks to + Bob Denny + +17-Nov-97 + - Quite a few internal cleanups, (removal of errno, and using macros + defined in e_os.h). + - A bug in ca.c, pointed out by yasuyuki-ito@d-cruise.co.jp, where + the automactic naming out output files was being stuffed up. + +29-Oct-97 + - The Cast5 cipher has been added. MD5 and SHA-1 are now in assember + for x86. + +21-Oct-97 + - Fixed a bug in the BIO_gethostbyname() cache. + +15-Oct-97 + - cbc mode for blowfish/des/3des is now in assember. Blowfish asm + has also been improved. At this point in time, on the pentium, + md5 is %80 faster, the unoptimesed sha-1 is %79 faster, + des-cbc is %28 faster, des-ede3-cbc is %9 faster and blowfish-cbc + is %62 faster. + +12-Oct-97 + - MEM_BUF_grow() has been fixed so that it always sets the buf->length + to the value we are 'growing' to. Think of MEM_BUF_grow() as the + way to set the length value correctly. + +10-Oct-97 + - I now hash for certificate lookup on the raw DER encoded RDN (md5). + This breaks things again :-(. This is efficent since I cache + the DER encoding of the RDN. + - The text DN now puts in the numeric OID instead of UNKNOWN. + - req can now process arbitary OIDs in the config file. + - I've been implementing md5 in x86 asm, much faster :-). + - Started sha1 in x86 asm, needs more work. + - Quite a few speedups in the BN stuff. RSA public operation + has been made faster by caching the BN_MONT_CTX structure. + The calulating of the Ai where A*Ai === 1 mod m was rather + expensive. Basically a 40-50% speedup on public operations. + The RSA speedup is now 15% on pentiums and %20 on pentium + pro. + +30-Sep-97 + - After doing some profiling, I added x86 adm for bn_add_words(), + which just adds 2 arrays of longs together. A %10 speedup + for 512 and 1024 bit RSA on the pentium pro. + +29-Sep-97 + - Converted the x86 bignum assembler to us the perl scripts + for generation. + +23-Sep-97 + - If SSL_set_session() is passed a NULL session, it now clears the + current session-id. + +22-Sep-97 + - Added a '-ss_cert file' to apps/ca.c. This will sign selfsigned + certificates. + - Bug in crypto/evp/encode.c where by decoding of 65 base64 + encoded lines, one line at a time (via a memory BIO) would report + EOF after the first line was decoded. + - Fix in X509_find_by_issuer_and_serial() from + Dr Stephen Henson + +19-Sep-97 + - NO_FP_API and NO_STDIO added. + - Put in sh config command. It auto runs Configure with the correct + parameters. + +18-Sep-97 + - Fix x509.c so if a DSA cert has different parameters to its parent, + they are left in place. Not tested yet. + +16-Sep-97 + - ssl_create_cipher_list() had some bugs, fixes from + Patrick Eisenacher + - Fixed a bug in the Base64 BIO, where it would return 1 instead + of -1 when end of input was encountered but should retry. + Basically a Base64/Memory BIO interaction problem. + - Added a HMAC set of functions in preporarion for TLS work. + +15-Sep-97 + - Top level makefile tweak - Cameron Simpson + - Prime generation spead up %25 (512 bit prime, pentium pro linux) + by using montgomery multiplication in the prime number test. + +11-Sep-97 + - Ugly bug in ssl3_write_bytes(). Basically if application land + does a SSL_write(ssl,buf,len) where len > 16k, the SSLv3 write code + did not check the size and tried to copy the entire buffer. + This would tend to cause memory overwrites since SSLv3 has + a maximum packet size of 16k. If your program uses + buffers <= 16k, you would probably never see this problem. + - Fixed a few errors that were cause by malloc() not returning + 0 initialised memory.. + - SSL_OP_NETSCAPE_CA_DN_BUG was being switched on when using + SSL_CTX_set_options(ssl_ctx,SSL_OP_ALL); which was a bad thing + since this flags stops SSLeay being able to handle client + cert requests correctly. + +08-Sep-97 + - SSL_SESS_CACHE_NO_INTERNAL_LOOKUP option added. When switched + on, the SSL server routines will not use a SSL_SESSION that is + held in it's cache. This in intended to be used with the session-id + callbacks so that while the session-ids are still stored in the + cache, the decision to use them and how to look them up can be + done by the callbacks. The are the 'new', 'get' and 'remove' + callbacks. This can be used to determine the session-id + to use depending on information like which port/host the connection + is coming from. Since the are also SSL_SESSION_set_app_data() and + SSL_SESSION_get_app_data() functions, the application can hold + information against the session-id as well. + +03-Sep-97 + - Added lookup of CRLs to the by_dir method, + X509_load_crl_file() also added. Basically it means you can + lookup CRLs via the same system used to lookup certificates. + - Changed things so that the X509_NAME structure can contain + ASN.1 BIT_STRINGS which is required for the unique + identifier OID. + - Fixed some problems with the auto flushing of the session-id + cache. It was not occuring on the server side. + +02-Sep-97 + - Added SSL_CTX_sess_cache_size(SSL_CTX *ctx,unsigned long size) + which is the maximum number of entries allowed in the + session-id cache. This is enforced with a simple FIFO list. + The default size is 20*1024 entries which is rather large :-). + The Timeout code is still always operating. + +01-Sep-97 + - Added an argument to all the 'generate private key/prime` + callbacks. It is the last parameter so this should not + break existing code but it is needed for C++. + - Added the BIO_FLAGS_BASE64_NO_NL flag for the BIO_f_base64() + BIO. This lets the BIO read and write base64 encoded data + without inserting or looking for '\n' characters. The '-A' + flag turns this on when using apps/enc.c. + - RSA_NO_PADDING added to help BSAFE functionality. This is a + very dangerous thing to use, since RSA private key + operations without random padding bytes (as PKCS#1 adds) can + be attacked such that the private key can be revealed. + - ASN.1 bug and rc2-40-cbc and rc4-40 added by + Dr Stephen Henson + +31-Aug-97 (stuff added while I was away) + - Linux pthreads by Tim Hudson (tjh@cryptsoft.com). + - RSA_flags() added allowing bypass of pub/priv match check + in ssl/ssl_rsa.c - Tim Hudson. + - A few minor bugs. + +SSLeay 0.8.1 released. + +19-Jul-97 + - Server side initated dynamic renegotiation is broken. I will fix + it when I get back from holidays. + +15-Jul-97 + - Quite a few small changes. + - INVALID_SOCKET usage cleanups from Alex Kiernan + +09-Jul-97 + - Added 2 new values to the SSL info callback. + SSL_CB_START which is passed when the SSL protocol is started + and SSL_CB_DONE when it has finished sucsessfully. + +08-Jul-97 + - Fixed a few bugs problems in apps/req.c and crypto/asn1/x_pkey.c + that related to DSA public/private keys. + - Added all the relevent PEM and normal IO functions to support + reading and writing RSAPublic keys. + - Changed makefiles to use ${AR} instead of 'ar r' + +07-Jul-97 + - Error in ERR_remove_state() that would leave a dangling reference + to a free()ed location - thanks to Alex Kiernan + - s_client now prints the X509_NAMEs passed from the server + when requesting a client cert. + - Added a ssl->type, which is one of SSL_ST_CONNECT or + SSL_ST_ACCEPT. I had to add it so I could tell if I was + a connect or an accept after the handshake had finished. + - SSL_get_client_CA_list(SSL *s) now returns the CA names + passed by the server if called by a client side SSL. + +05-Jul-97 + - Bug in X509_NAME_get_text_by_OBJ(), looking starting at index + 0, not -1 :-( Fix from Tim Hudson (tjh@cryptsoft.com). + +04-Jul-97 + - Fixed some things in X509_NAME_add_entry(), thanks to + Matthew Donald . + - I had a look at the cipher section and though that it was a + bit confused, so I've changed it. + - I was not setting up the RC4-64-MD5 cipher correctly. It is + a MS special that appears in exported MS Money. + - Error in all my DH ciphers. Section 7.6.7.3 of the SSLv3 + spec. I was missing the two byte length header for the + ClientDiffieHellmanPublic value. This is a packet sent from + the client to the server. The SSL_OP_SSLEAY_080_CLIENT_DH_BUG + option will enable SSLeay server side SSLv3 accept either + the correct or my 080 packet format. + - Fixed a few typos in crypto/pem.org. + +02-Jul-97 + - Alias mapping for EVP_get_(digest|cipher)byname is now + performed before a lookup for actual cipher. This means + that an alias can be used to 're-direct' a cipher or a + digest. + - ASN1_read_bio() had a bug that only showed up when using a + memory BIO. When EOF is reached in the memory BIO, it is + reported as a -1 with BIO_should_retry() set to true. + +01-Jul-97 + - Fixed an error in X509_verify_cert() caused by my + miss-understanding how 'do { contine } while(0);' works. + Thanks to Emil Sit for educating me :-) + +30-Jun-97 + - Base64 decoding error. If the last data line did not end with + a '=', sometimes extra data would be returned. + - Another 'cut and paste' bug in x509.c related to setting up the + STDout BIO. + +27-Jun-97 + - apps/ciphers.c was not printing due to an editing error. + - Alex Kiernan send in a nice fix for + a library build error in util/mk1mf.pl + +26-Jun-97 + - Still did not have the auto 'experimental' code removal + script correct. + - A few header tweaks for Watcom 11.0 under Win32 from + Rolf Lindemann + - 0 length OCTET_STRING bug in asn1_parse + - A minor fix with an non-existent function in the MS .def files. + - A few changes to the PKCS7 stuff. + +25-Jun-97 + SSLeay 0.8.0 finally it gets released. + +24-Jun-97 + Added a SSL_OP_EPHEMERAL_RSA option which causes all SSLv3 RSA keys to + use a temporary RSA key. This is experimental and needs some more work. + Fixed a few Win16 build problems. + +23-Jun-97 + SSLv3 bug. I was not doing the 'lookup' of the CERT structure + correctly. I was taking the SSL->ctx->default_cert when I should + have been using SSL->cert. The bug was in ssl/s3_srvr.c + +20-Jun-97 + X509_ATTRIBUTES were being encoded wrongly by apps/reg.c and the + rest of the library. Even though I had the code required to do + it correctly, apps/req.c was doing the wrong thing. I have fixed + and tested everything. + + Missing a few #ifdef FIONBIO sections in crypto/bio/bss_acpt.c. + +19-Jun-97 + Fixed a bug in the SSLv2 server side first packet handling. When + using the non-blocking test BIO, the ssl->s2->first_packet flag + was being reset when a would-block failure occurred when reading + the first 5 bytes of the first packet. This caused the checking + logic to run at the wrong time and cause an error. + + Fixed a problem with specifying cipher. If RC4-MD5 were used, + only the SSLv3 version would be picked up. Now this will pick + up both SSLv2 and SSLv3 versions. This required changing the + SSL_CIPHER->mask values so that they only mask the ciphers, + digests, authentication, export type and key-exchange algorithms. + + I found that when a SSLv23 session is established, a reused + session, of type SSLv3 was attempting to write the SSLv2 + ciphers, which were invalid. The SSL_METHOD->put_cipher_by_char + method has been modified so it will only write out cipher which + that method knows about. + + + Changes between 0.8.0 and 0.8.1 + + *) Mostly bug fixes. + There is an Ephemeral DH cipher problem which is fixed. + + SSLeay 0.8.0 + +This version of SSLeay has quite a lot of things different from the +previous version. + +Basically check all callback parameters, I will be producing documentation +about how to use things in th future. Currently I'm just getting 080 out +the door. Please not that there are several ways to do everything, and +most of the applications in the apps directory are hybrids, some using old +methods and some using new methods. + +Have a look in demos/bio for some very simple programs and +apps/s_client.c and apps/s_server.c for some more advanced versions. +Notes are definitly needed but they are a week or so away. + +Anyway, some quick nots from Tim Hudson (tjh@cryptsoft.com) +--- +Quick porting notes for moving from SSLeay-0.6.x to SSLeay-0.8.x to +get those people that want to move to using the new code base off to +a quick start. + +Note that Eric has tidied up a lot of the areas of the API that were +less than desirable and renamed quite a few things (as he had to break +the API in lots of places anyrate).

"cert" is no longer a direct member of this +structure ... things are now down under "cert_store" (see x509_vfy.h) and +things are no longer in a CERTIFICATE_CTX but instead in a X509_STORE. +If your code "knows" about this level of detail then it will need some +surgery. + +If you depending on the incorrect spelling of a number of the error codes +then you will have to change your code as these have been fixed. + +ENV_CIPHER "type" got renamed to "nid" and as that is what it actually +has been all along so this makes things clearer. +ify_cert_error_string(ctx->error)); + +SSL_R_NO_CIPHER_WE_TRUST -> SSL_R_NO_CIPHER_LIST + and SSL_R_REUSE_CIPHER_LIST_NOT_ZERO + + + + Changes between 0.7.x and 0.8.0 + + *) There have been lots of changes, mostly the addition of SSLv3. + There have been many additions from people and amongst + others, C2Net has assisted greatly. + + Changes between 0.7.x and 0.7.x + + *) Internal development version only + +SSLeay 0.6.6 13-Jan-1997 + +The main additions are + +- assember for x86 DES improvments. + From 191,000 per second on a pentium 100, I now get 281,000. The inner + loop and the IP/FP modifications are from + Svend Olaf Mikkelsen . Many thanks for his + contribution. +- The 'DES macros' introduced in 0.6.5 now have 3 types. + DES_PTR1, DES_PTR2 and 'normal'. As per before, des_opts reports which + is best and there is a summery of mine in crypto/des/options.txt +- A few bug fixes. +- Added blowfish. It is not used by SSL but all the other stuff that + deals with ciphers can use it in either ecb, cbc, cfb64 or ofb64 modes. + There are 3 options for optimising Blowfish. BF_PTR, BF_PTR2 and 'normal'. + BF_PTR2 is pentium/x86 specific. The correct option is setup in + the 'Configure' script. +- There is now a 'get client certificate' callback which can be + 'non-blocking'. If more details are required, let me know. It will + documented more in SSLv3 when I finish it. +- Bug fixes from 0.6.5 including the infamous 'ca' bug. The 'make test' + now tests the ca program. +- Lots of little things modified and tweaked. + + SSLeay 0.6.5 + +After quite some time (3 months), the new release. I have been very busy +for the last few months and so this is mostly bug fixes and improvments. + +The main additions are + +- assember for x86 DES. For all those gcc based systems, this is a big + improvement. From 117,000 DES operation a second on a pentium 100, + I now get 191,000. I have also reworked the C version so it + now gives 148,000 DESs per second. +- As mentioned above, the inner DES macros now have some more variant that + sometimes help, sometimes hinder performance. There are now 3 options + DES_PTR (ptr vs array lookup), DES_UNROLL (full vs partial loop unrolling) + and DES_RISC (a more register intensive version of the inner macro). + The crypto/des/des_opts.c program, when compiled and run, will give + an indication of the correct options to use. +- The BIO stuff has been improved. Read doc/bio.doc. There are now + modules for encryption and base64 encoding and a BIO_printf() function. +- The CA program will accept simple one line X509v3 extensions in the + ssleay.cnf file. Have a look at the example. Currently this just + puts the text into the certificate as an OCTET_STRING so currently + the more advanced X509v3 data types are not handled but this is enough + for the netscape extensions. +- There is the start of a nicer higher level interface to the X509 + strucutre. +- Quite a lot of bug fixes. +- CRYPTO_malloc_init() (or CRYPTO_set_mem_functions()) can be used + to define the malloc(), free() and realloc() routines to use + (look in crypto/crypto.h). This is mostly needed for Windows NT/95 when + using DLLs and mixing CRT libraries. + +In general, read the 'VERSION' file for changes and be aware that some of +the new stuff may not have been tested quite enough yet, so don't just plonk +in SSLeay 0.6.5 when 0.6.4 used to work and expect nothing to break. + +SSLeay 0.6.4 30/08/96 eay + +I've just finished some test builds on Windows NT, Windows 3.1, Solaris 2.3, +Solaris 2.5, Linux, IRIX, HPUX 10 and everthing seems to work :-). + +The main changes in this release + +- Thread safe. have a read of doc/threads.doc and play in the mt directory. + For anyone using 0.6.3 with threads, I found 2 major errors so consider + moving to 0.6.4. I have a test program that builds under NT and + solaris. +- The get session-id callback has changed. Have a read of doc/callback.doc. +- The X509_cert_verify callback (the SSL_verify callback) now + has another argument. Have a read of doc/callback.doc +- 'ca -preserve', sign without re-ordering the DN. Not tested much. +- VMS support. +- Compile time memory leak detection can now be built into SSLeay. + Read doc/memory.doc +- CONF routines now understand '\', '\n', '\r' etc. What this means is that + the SPKAC object mentioned in doc/ns-ca.doc can be on multiple lines. +- 'ssleay ciphers' added, lists the default cipher list for SSLeay. +- RC2 key setup is now compatable with Netscape. +- Modifed server side of SSL implementation, big performance difference when + using session-id reuse. + +0.6.3 + +Bug fixes and the addition of some nice stuff to the 'ca' program. +Have a read of doc/ns-ca.doc for how hit has been modified so +it can be driven from a CGI script. The CGI script is not provided, +but that is just being left as an excersize for the reader :-). + +0.6.2 + +This is most bug fixes and functionality improvements. + +Additions are +- More thread debugging patches, the thread stuff is still being + tested, but for those keep to play with stuff, have a look in + crypto/cryptlib.c. The application needs to define 1 (or optionaly + a second) callback that is used to implement locking. Compiling + with LOCK_DEBUG spits out lots of locking crud :-). + This is what I'm currently working on. +- SSL_CTX_set_default_passwd_cb() can be used to define the callback + function used in the SSL*_file() functions used to load keys. I was + always of the opinion that people should call + PEM_read_RSAPrivateKey() and pass the callback they want to use, but + it appears they just want to use the SSL_*_file() function() :-(. +- 'enc' now has a -kfile so a key can be read from a file. This is + mostly used so that the passwd does not appear when using 'ps', + which appears imposible to stop under solaris. +- X509v3 certificates now work correctly. I even have more examples + in my tests :-). There is now a X509_EXTENSION type that is used in + X509v3 certificates and CRLv2. +- Fixed that signature type error :-( +- Fixed quite a few potential memory leaks and problems when reusing + X509, CRL and REQ structures. +- EVP_set_pw_prompt() now sets the library wide default password + prompt. +- The 'pkcs7' command will now, given the -print_certs flag, output in + pem format, all certificates and CRL contained within. This is more + of a pre-emtive thing for the new verisign distribution method. I + should also note, that this also gives and example in code, of how + to do this :-), or for that matter, what is involved in going the + other way (list of certs and crl -> pkcs7). +- Added RSA's DESX to the DES library. It is also available via the + EVP_desx_cbc() method and via 'enc desx'. + +SSLeay 0.6.1 + +The main functional changes since 0.6.0 are as follows +- Bad news, the Microsoft 060 DLL's are not compatable, but the good news is + that from now on, I'll keep the .def numbers the same so they will be. +- RSA private key operations are about 2 times faster that 0.6.0 +- The SSL_CTX now has more fields so default values can be put against + it. When an SSL structure is created, these default values are used + but can be overwritten. There are defaults for cipher, certificate, + private key, verify mode and callback. This means SSL session + creation can now be + ssl=SSL_new() + SSL_set_fd(ssl,sock); + SSL_accept(ssl) + .... + All the other uglyness with having to keep a global copy of the + private key and certificate/verify mode in the server is now gone. +- ssl/ssltest.c - one process talking SSL to its self for testing. +- Storage of Session-id's can be controled via a session_cache_mode + flag. There is also now an automatic default flushing of + old session-id's. +- The X509_cert_verify() function now has another parameter, this + should not effect most people but it now means that the reason for + the failure to verify is now available via SSL_get_verify_result(ssl). + You don't have to use a global variable. +- SSL_get_app_data() and SSL_set_app_data() can be used to keep some + application data against the SSL structure. It is upto the application + to free the data. I don't use it, but it is available. +- SSL_CTX_set_cert_verify_callback() can be used to specify a + verify callback function that completly replaces my certificate + verification code. Xcert should be able to use this :-). + The callback is of the form int app_verify_callback(arg,ssl,cert). + This needs to be documented more. +- I have started playing with shared library builds, have a look in + the shlib directory. It is very simple. If you need a numbered + list of functions, have a look at misc/crypto.num and misc/ssl.num. +- There is some stuff to do locking to make the library thread safe. + I have only started this stuff and have not finished. If anyone is + keen to do so, please send me the patches when finished. + +So I have finally made most of the additions to the SSL interface that +I thought were needed. + +There will probably be a pause before I make any non-bug/documentation +related changes to SSLeay since I'm feeling like a bit of a break. + +eric - 12 Jul 1996 +I saw recently a comment by some-one that we now seem to be entering +the age of perpetual Beta software. +Pioneered by packages like linux but refined to an art form by +netscape. + +I too wish to join this trend with the anouncement of SSLeay 0.6.0 :-). + +There are quite a large number of sections that are 'works in +progress' in this package. I will also list the major changes and +what files you should read. + +BIO - this is the new IO structure being used everywhere in SSLeay. I +started out developing this because of microsoft, I wanted a mechanism +to callback to the application for all IO, so Windows 3.1 DLL +perversion could be hidden from me and the 15 different ways to write +to a file under NT would also not be dictated by me at library build +time. What the 'package' is is an API for a data structure containing +functions. IO interfaces can be written to conform to the +specification. This in not intended to hide the underlying data type +from the application, but to hide it from SSLeay :-). +I have only really finished testing the FILE * and socket/fd modules. +There are also 'filter' BIO's. Currently I have only implemented +message digests, and it is in use in the dgst application. This +functionality will allow base64/encrypto/buffering modules to be +'push' into a BIO without it affecting the semantics. I'm also +working on an SSL BIO which will hide the SSL_accept()/SLL_connet() +from an event loop which uses the interface. +It is also possible to 'attach' callbacks to a BIO so they get called +before and after each operation, alowing extensive debug output +to be generated (try running dgst with -d). + +Unfortunaly in the conversion from 0.5.x to 0.6.0, quite a few +functions that used to take FILE *, now take BIO *. +The wrappers are easy to write + +function_fp(fp,x) +FILE *fp; + { + BIO *b; + int ret; + + if ((b=BIO_new(BIO_s_file())) == NULL) error..... + BIO_set_fp(b,fp,BIO_NOCLOSE); + ret=function_bio(b,x); + BIO_free(b); + return(ret); + } +Remember, there are no functions that take FILE * in SSLeay when +compiled for Windows 3.1 DLL's. + +-- +I have added a general EVP_PKEY type that can hold a public/private +key. This is now what is used by the EVP_ functions and is passed +around internally. I still have not done the PKCS#8 stuff, but +X509_PKEY is defined and waiting :-) + +-- +For a full function name listings, have a look at ms/crypt32.def and +ms/ssl32.def. These are auto-generated but are complete. +Things like ASN1_INTEGER_get() have been added and are in here if you +look. I have renamed a few things, again, have a look through the +function list and you will probably find what you are after. I intend +to at least put a one line descrition for each one..... + +-- +Microsoft - thats what this release is about, read the MICROSOFT file. + +-- +Multi-threading support. I have started hunting through the code and +flaging where things need to be done. In a state of work but high on +the list. + +-- +For random numbers, edit e_os.h and set DEVRANDOM (it's near the top) +be be you random data device, otherwise 'RFILE' in e_os.h +will be used, in your home directory. It will be updated +periodically. The environment variable RANDFILE will override this +choice and read/write to that file instead. DEVRANDOM is used in +conjunction to the RFILE/RANDFILE. If you wish to 'seed' the random +number generator, pick on one of these files. + +-- + +The list of things to read and do + +dgst -d +s_client -state (this uses a callback placed in the SSL state loop and + will be used else-where to help debug/monitor what + is happening.) + +doc/why.doc +doc/bio.doc <- hmmm, needs lots of work. +doc/bss_file.doc <- one that is working :-) +doc/session.doc <- it has changed +doc/speed.doc + also play with ssleay version -a. I have now added a SSLeay() + function that returns a version number, eg 0600 for this release + which is primarily to be used to check DLL version against the + application. +util/* Quite a few will not interest people, but some may, like + mk1mf.pl, mkdef.pl, +util/do_ms.sh + +try +cc -Iinclude -Icrypto -c crypto/crypto.c +cc -Iinclude -Issl -c ssl/ssl.c +You have just built the SSLeay libraries as 2 object files :-) + +Have a general rummage around in the bin stall directory and look at +what is in there, like CA.sh and c_rehash + +There are lots more things but it is 12:30am on a Friday night and I'm +heading home :-). + +eric 22-Jun-1996 +This version has quite a few major bug fixes and improvements. It DOES NOT +do SSLv3 yet. + +The main things changed +- A Few days ago I added the s_mult application to ssleay which is + a demo of an SSL server running in an event loop type thing. + It supports non-blocking IO, I have finally gotten it right, SSL_accept() + can operate in non-blocking IO mode, look at the code to see how :-). + Have a read of doc/s_mult as well. This program leaks memory and + file descriptors everywhere but I have not cleaned it up yet. + This is a demo of how to do non-blocking IO. +- The SSL session management has been 'worked over' and there is now + quite an expansive set of functions to manipulate them. Have a read of + doc/session.doc for some-things I quickly whipped up about how it now works. + This assume you know the SSLv2 protocol :-) +- I can now read/write the netscape certificate format, use the + -inform/-outform 'net' options to the x509 command. I have not put support + for this type in the other demo programs, but it would be easy to add. +- asn1parse and 'enc' have been modified so that when reading base64 + encoded files (pem format), they do not require '-----BEGIN' header lines. + The 'enc' program had a buffering bug fixed, it can be used as a general + base64 -> binary -> base64 filter by doing 'enc -a -e' and 'enc -a -d' + respecivly. Leaving out the '-a' flag in this case makes the 'enc' command + into a form of 'cat'. +- The 'x509' and 'req' programs have been fixed and modified a little so + that they generate self-signed certificates correctly. The test + script actually generates a 'CA' certificate and then 'signs' a + 'user' certificate. Have a look at this shell script (test/sstest) + to see how things work, it tests most possible combinations of what can + be done. +- The 'SSL_set_pref_cipher()' function has been 'fixed' and the prefered name + of SSL_set_cipher_list() is now the correct API (stops confusion :-). + If this function is used in the client, only the specified ciphers can + be used, with preference given to the order the ciphers were listed. + For the server, if this is used, only the specified ciphers will be used + to accept connections. If this 'option' is not used, a default set of + ciphers will be used. The SSL_CTX_set_cipher_list(SSL_CTX *ctx) sets this + list for all ciphers started against the SSL_CTX. So the order is + SSL cipher_list, if not present, SSL_CTX cipher list, if not + present, then the library default. + What this means is that normally ciphers like + NULL-MD5 will never be used. The only way this cipher can be used + for both ends to specify to use it. + To enable or disable ciphers in the library at build time, modify the + first field for the cipher in the ssl_ciphers array in ssl/ssl_lib.c. + This file also contains the 'pref_cipher' list which is the default + cipher preference order. +- I'm not currently sure if the 'rsa -inform net' and the 'rsa -outform net' + options work. They should, and they enable loading and writing the + netscape rsa private key format. I will be re-working this section of + SSLeay for the next version. What is currently in place is a quick and + dirty hack. +- I've re-written parts of the bignum library. This gives speedups + for all platforms. I now provide assembler for use under Windows NT. + I have not tested the Windows 3.1 assembler but it is quite simple code. + This gives RSAprivate_key operation encryption times of 0.047s (512bit key) + and 0.230s (1024bit key) on a pentium 100 which I consider reasonable. + Basically the times available under linux/solaris x86 can be achieve under + Windows NT. I still don't know how these times compare to RSA's BSAFE + library but I have been emailing with people and with their help, I should + be able to get my library's quite a bit faster still (more algorithm changes). + The object file crypto/bn/asm/x86-32.obj should be used when linking + under NT. +- 'make makefile.one' in the top directory will generate a single makefile + called 'makefile.one' This makefile contains no perl references and + will build the SSLeay library into the 'tmp' and 'out' directories. + util/mk1mf.pl >makefile.one is how this makefile is + generated. The mk1mf.pl command take several option to generate the + makefile for use with cc, gcc, Visual C++ and Borland C++. This is + still under development. I have only build .lib's for NT and MSDOS + I will be working on this more. I still need to play with the + correct compiler setups for these compilers and add some more stuff but + basically if you just want to compile the library + on a 'non-unix' platform, this is a very very good file to start with :-). + Have a look in the 'microsoft' directory for my current makefiles. + I have not yet modified things to link with sockets under Windows NT. + You guys should be able to do this since this is actually outside of the + SSLeay scope :-). I will be doing it for myself soon. + util/mk1mf.pl takes quite a few options including no-rc, rsaref and no-sock + to build without RC2/RC4, to require RSAref for linking, and to + build with no socket code. + +- Oh yes, the cipher that was reported to be compatible with RSA's RC2 cipher + that was posted to sci.crypt has been added to the library and SSL. + I take the view that if RC2 is going to be included in a standard, + I'll include the cipher to make my package complete. + There are NO_RC2, NO_RC4 and NO_IDEA macros to remove these ciphers + at compile time. I have not tested this recently but it should all work + and if you are in the USA and don't want RSA threatening to sue you, + you could probably remove the RC4/RC2 code inside these sections. + I may in the future include a perl script that does this code + removal automatically for those in the USA :-). +- I have removed all references to sed in the makefiles. So basically, + the development environment requires perl and sh. The build environment + does not (use the makefile.one makefile). + The Configure script still requires perl, this will probably stay that way + since I have perl for Windows NT :-). + +eric (03-May-1996) + +PS Have a look in the VERSION file for more details on the changes and + bug fixes. +I have fixed a few bugs, added alpha and x86 assembler and generally cleaned +things up. This version will be quite stable, mostly because I'm on +holidays until 10-March-1996. For any problems in the interum, send email +to Tim Hudson . + +SSLeay 0.5.0 + +12-12-95 +This is going out before it should really be released. + +I leave for 11 weeks holidays on the 22-12-95 and so I either sit on +this for 11 weeks or get things out. It is still going to change a +lot in the next week so if you do grab this version, please test and +give me feed back ASAP, inculuding questions on how to do things with +the library. This will prompt me to write documentation so I don't +have to answer the same question again :-). + +This 'pre' release version is for people who are interested in the +library. The applications will have to be changed to use +the new version of the SSL interface. I intend to finish more +documentation before I leave but until then, look at the programs in +the apps directory. As far as code goes, it is much much nicer than +the old version. + +The current library works, has no memory leaks (as far as I can tell) +and is far more bug free that 0.4.5d. There are no global variable of +consequence (I believe) and I will produce some documentation that +tell where to look for those people that do want to do multi-threaded +stuff. + +There should be more documentation. Have a look in the +doc directory. I'll be adding more before I leave, it is a start +by mostly documents the crypto library. Tim Hudson will update +the web page ASAP. The spelling and grammar are crap but +it is better than nothing :-) + +Reasons to start playing with version 0.5.0 +- All the programs in the apps directory build into one ssleay binary. +- There is a new version of the 'req' program that generates certificate + requests, there is even documentation for this one :-) +- There is a demo certification authorithy program. Currently it will + look at the simple database and update it. It will generate CRL from + the data base. You need to edit the database by hand to revoke a + certificate, it is my aim to use perl5/Tk but I don't have time to do + this right now. It will generate the certificates but the management + scripts still need to be written. This is not a hard task. +- Things have been cleaned up alot. +- Have a look at the enc and dgst programs in the apps directory. +- It supports v3 of x509 certiticates. + + +Major things missing. +- I have been working on (and thinging about) the distributed x509 + hierachy problem. I have not had time to put my solution in place. + It will have to wait until I come back. +- I have not put in CRL checking in the certificate verification but + it would not be hard to do. I was waiting until I could generate my + own CRL (which has only been in the last week) and I don't have time + to put it in correctly. +- Montgomery multiplication need to be implemented. I know the + algorithm, just ran out of time. +- PKCS#7. I can load and write the DER version. I need to re-work + things to support BER (if that means nothing, read the ASN1 spec :-). +- Testing of the higher level digital envelope routines. I have not + played with the *_seal() and *_open() type functions. They are + written but need testing. The *_sign() and *_verify() functions are + rock solid. +- PEM. Doing this and PKCS#7 have been dependant on the distributed + x509 heirachy problem. I started implementing my ideas, got + distracted writing a CA program and then ran out of time. I provide + the functionality of RSAref at least. +- Re work the asm. code for the x86. I've changed by low level bignum + interface again, so I really need to tweak the x86 stuff. gcc is + good enough for the other boxes. + diff --git a/CONTRIBUTING b/CONTRIBUTING new file mode 100644 index 0000000..efcb0b8 --- /dev/null +++ b/CONTRIBUTING @@ -0,0 +1,54 @@ +HOW TO CONTRIBUTE TO OpenSSL +---------------------------- + +(Please visit https://www.openssl.org/community/getting-started.html for +other ideas about how to contribute.) + +Development is done on GitHub, https://github.com/openssl/openssl. + +To request new features or report bugs, please open an issue on GitHub + +To submit a patch, please open a pull request on GitHub.

If no prefix is specified, + the library files and binaries are also installed there. + + no-threads Don't try to build with support for multi-threaded + applications. + + threads Build with support for multi-threaded applications. + This will usually require additional system-dependent options! + See "Note on multi-threading" below. + + no-zlib Don't try to build with support for zlib compression and + decompression. + + zlib Build with support for zlib compression/decompression. + + zlib-dynamic Like "zlib", but has OpenSSL load the zlib library dynamically + when needed. This is only supported on systems where loading + of shared libraries is supported.

See "Note on + shared libraries" below. + + no-asm Do not use assembler code. + + 386 In 32-bit x86 builds, when generating assembly modules, + use the 80386 instruction set only (the default x86 code + is more efficient, but requires at least a 486). Note: + This doesn't affect code generated by compiler, you're + likely to complement configuration command line with + suitable compiler-specific option. + + no-sse2 Exclude SSE2 code paths from 32-bit x86 assembly modules. + Normally SSE2 extension is detected at run-time, but the + decision whether or not the machine code will be executed + is taken solely on CPU capability vector.

Configure OpenSSL for your operation system automatically: + + $ ./config [options] + + This guesses at your operating system (and compiler, if necessary) and + configures OpenSSL based on this guess. Run ./config -t to see + if it guessed correctly. If you want to use a different compiler, you + are cross-compiling for another platform, or the ./config guess was + wrong for other reasons, go to step 1b. Otherwise go to step 2. + + On some systems, you can include debugging information as follows: + + $ ./config -d [options] + + 1b. Configure OpenSSL for your operating system manually + + OpenSSL knows about a range of different operating system, hardware and + compiler combinations. To see the ones it knows about, run + + $ ./Configure + + Pick a suitable name from the list that matches your system. For most + operating systems there is a choice between using "cc" or "gcc". When + you have identified your system (and if necessary compiler) use this name + as the argument to ./Configure. For example, a "linux-elf" user would + run: + + $ ./Configure linux-elf [options] + + If your system is not available, you will have to edit the Configure + program and add the correct configuration for your system. The + generic configurations "cc" or "gcc" should usually work on 32 bit + systems. + + Configure creates the file Makefile.ssl from Makefile.org and + defines various macros in crypto/opensslconf.h (generated from + crypto/opensslconf.h.in). + + 2. Build OpenSSL by running: + + $ make + + This will build the OpenSSL libraries (libcrypto.a and libssl.a) and the + OpenSSL binary ("openssl"). The libraries will be built in the top-level + directory, and the binary will be in the "apps" directory. + + If the build fails, look at the output. There may be reasons + for the failure that aren't problems in OpenSSL itself (like + missing standard headers). If you are having problems you can + get help by sending an email to the openssl-users email list (see + https://www.openssl.org/community/mailinglists.html for details). If + it is a bug with OpenSSL itself, please open an issue on GitHub, at + https://github.com/openssl/openssl/issues. Please review the existing + ones first; maybe the bug was already reported or has already been + fixed. + + (If you encounter assembler error messages, try the "no-asm" + configuration option as an immediate fix.) + + Compiling parts of OpenSSL with gcc and others with the system + compiler will result in unresolved symbols on some systems. + + 3. After a successful build, the libraries should be tested. Run: + + $ make test + + If a test fails, look at the output. There may be reasons for + the failure that isn't a problem in OpenSSL itself (like a missing + or malfunctioning bc). If it is a problem with OpenSSL itself, + try removing any compiler optimization flags from the CFLAG line + in Makefile.ssl and run "make clean; make". To report a bug please open an + issue on GitHub, at https://github.com/openssl/openssl/issues. + + 4. If everything tests ok, install OpenSSL with + + $ make install + + This will create the installation directory (if it does not exist) and + then the following subdirectories: + + certs Initially empty, this is the default location + for certificate files. + man/man1 Manual pages for the 'openssl' command line tool + man/man3 Manual pages for the libraries (very incomplete) + misc Various scripts. + private Initially empty, this is the default location + for private key files. + + If you didn't choose a different installation prefix, the + following additional subdirectories will be created: + + bin Contains the openssl binary and a few other + utility programs. + include/openssl Contains the header files needed if you want to + compile programs with libcrypto or libssl. + lib Contains the OpenSSL library files themselves. + + Use "make install_sw" to install the software without documentation, + and "install_docs_html" to install HTML renditions of the manual + pages. + + Package builders who want to configure the library for standard + locations, but have the package installed somewhere else so that + it can easily be packaged, can use + + $ make INSTALL_PREFIX=/tmp/package-root install + + (or specify "--install_prefix=/tmp/package-root" as a configure + option). The specified prefix will be prepended to all + installation target filenames. + + + NOTE: The header files used to reside directly in the include + directory, but have now been moved to include/openssl so that + OpenSSL can co-exist with other libraries which use some of the + same filenames. This means that applications that use OpenSSL + should now use C preprocessor directives of the form + + #include + + instead of "#include ", which was used with library versions + up to OpenSSL 0.9.2b. + + If you install a new version of OpenSSL over an old library version, + you should delete the old header files in the include directory. + + Compatibility issues: + + * COMPILING existing applications + + To compile an application that uses old filenames -- e.g. + "#include " --, it will usually be enough to find + the CFLAGS definition in the application's Makefile and + add a C option such as + + -I/usr/local/ssl/include/openssl + + to it. + + But don't delete the existing -I option that points to + the ..../include directory! Otherwise, OpenSSL header files + could not #include each other. + + * WRITING applications + + To write an application that is able to handle both the new + and the old directory layout, so that it can still be compiled + with library versions up to OpenSSL 0.9.2b without bothering + the user, you can proceed as follows: + + - Always use the new filename of OpenSSL header files, + e.g. #include . + + - Create a directory "incl" that contains only a symbolic + link named "openssl", which points to the "include" directory + of OpenSSL. + For example, your application's Makefile might contain the + following rule, if OPENSSLDIR is a pathname (absolute or + relative) of the directory where OpenSSL resides: + + incl/openssl: + -mkdir incl + cd $(OPENSSLDIR) # Check whether the directory really exists + -ln -s `cd $(OPENSSLDIR); pwd`/include incl/openssl + + You will have to add "incl/openssl" to the dependencies + of those C files that include some OpenSSL header file. + + - Add "-Iincl" to your CFLAGS. + + With these additions, the OpenSSL header files will be available + under both name variants if an old library version is used: + Your application can reach them under names like , + while the header files still are able to #include each other + with names of the form . + + + Note on multi-threading + ----------------------- + + For some systems, the OpenSSL Configure script knows what compiler options + are needed to generate a library that is suitable for multi-threaded + applications. On these systems, support for multi-threading is enabled + by default; use the "no-threads" option to disable (this should never be + necessary). + + On other systems, to enable support for multi-threading, you will have + to specify at least two options: "threads", and a system-dependent option. + (The latter is "-D_REENTRANT" on various systems.) The default in this + case, obviously, is not to include support for multi-threading (but + you can still use "no-threads" to suppress an annoying warning message + from the Configure script.) + + + Note on shared libraries + ------------------------ + + Shared libraries have certain caveats. Binary backward compatibility + can't be guaranteed before OpenSSL version 1.0. The only reason to + use them would be to conserve memory on systems where several programs + are using OpenSSL. + + For some systems, the OpenSSL Configure script knows what is needed to + build shared libraries for libcrypto and libssl. On these systems, + the shared libraries are currently not created by default, but giving + the option "shared" will get them created. This method supports Makefile + targets for shared library creation, like linux-shared. Those targets + can currently be used on their own just as well, but this is expected + to change in future versions of OpenSSL. + + Note on random number generation + -------------------------------- + + Availability of cryptographically secure random numbers is required for + secret key generation. OpenSSL provides several options to seed the + internal PRNG. If not properly seeded, the internal PRNG will refuse + to deliver random bytes and a "PRNG not seeded error" will occur. + On systems without /dev/urandom (or similar) device, it may be necessary + to install additional support software to obtain random seed. + Please check out the manual pages for RAND_add(), RAND_bytes(), RAND_egd(), + and the FAQ for more information. + + Note on support for multiple builds + ----------------------------------- + + OpenSSL is usually built in its source tree. Unfortunately, this doesn't + support building for multiple platforms from the same source tree very well. + It is however possible to build in a separate tree through the use of lots + of symbolic links, which should be prepared like this: + + mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`" + cd objtree/"`uname -s`-`uname -r`-`uname -m`" + (cd $OPENSSL_SOURCE; find . -type f) | while read F; do + mkdir -p `dirname $F` + rm -f $F; ln -s $OPENSSL_SOURCE/$F $F + echo $F '->' $OPENSSL_SOURCE/$F + done + make -f Makefile.org clean + + OPENSSL_SOURCE is an environment variable that contains the absolute (this + is important!) path to the OpenSSL source tree. + + Also, operations like 'make update' should still be made in the source tree. diff --git a/INSTALL.DJGPP b/INSTALL.DJGPP new file mode 100644 index 0000000..1047ec9 --- /dev/null +++ b/INSTALL.DJGPP @@ -0,0 +1,47 @@ + + + INSTALLATION ON THE DOS PLATFORM WITH DJGPP + ------------------------------------------- + + OpenSSL has been ported to DJGPP, a Unix look-alike 32-bit run-time + environment for 16-bit DOS, but only with long filename support. + If you wish to compile on native DOS with 8+3 filenames, you will + have to tweak the installation yourself, including renaming files + with illegal or duplicate names. + + You should have a full DJGPP environment installed, including the + latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package + requires that PERL and BC also be installed. + + All of these can be obtained from the usual DJGPP mirror sites or + directly at "http://www.delorie.com/pub/djgpp".

They may require some +modifications. + + +Supported NetWare Platforms - NetWare 5.x, NetWare 6.x: +------------------------------------------------------- +OpenSSL can either use the WinSock interfaces introduced in NetWare 5, +or the BSD socket interface. Previous versions of NetWare, 4.x and 3.x, +are only supported if OpenSSL is build for CLIB and BSD sockets; +WinSock builds only support NetWare 5 and up. + +On NetWare there are two c-runtime libraries. There is the legacy CLIB +interfaces and the newer LIBC interfaces.

CAUTION: If a directory with the +name of "OpenSSL" already exists, it will be deleted. + +To run cpy_tests.bat: + + netware\cpy_tests [output directory] [NetWare drive] + + output directory - "out_nw_clib.dbg", "out_nw_libc", etc. + NetWare drive - drive letter of mapped drive + + CLIB ex: netware\cpy_tests out_nw_clib m: + LIBC ex: netware\cpy_tests out_nw_libc m: + + +The Perl script, "do_tests.pl", in the "OpenSSL" directory on the server +should be used to execute the tests.

Any errors will be denoted by the word +"ERROR" in the log. + +DEVELOPING WITH THE OPENSSL SDK: +-------------------------------- +Now that everything is built and tested, you are ready to use the OpenSSL +libraries in your development. + +There is no real installation procedure, just copy the static libs and +headers to your build location. The libs (crypto.lib & ssl.lib) are +located in the appropriate "out_nw_XXXX" directory +(out_nw_clib, out_nw_libc, etc). + +The headers are located in the appropriate "outinc_nw_XXX" directory +(outinc_nw_clib, outinc_nw_libc). + +One suggestion is to create the following directory +structure for the OpenSSL SDK: + + \openssl + |- bin + | |- openssl.nlm + | |- (other tests you want) + | + |- lib + | | - crypto.lib + | | - ssl.lib + | + |- include + | | - openssl + | | | - (all the headers in "outinc_nw\openssl") + + +The program "openssl.nlm" can be very useful. It has dozens of +options and you may want to keep it handy for debugging, testing, etc. + +When building your apps using OpenSSL, define "NETWARE". It is needed by +some of the OpenSSL headers. One way to do this is with a compile option, +for example "-DNETWARE". + + + +NOTES: +------ + +Resource leaks in Tests +------------------------ +Some OpenSSL tests do not clean up resources and NetWare reports +the resource leaks when the tests unload. If this really bugs you, +you can stop the messages by setting the developer option off at the console +prompt (set developer option = off). Or better yet, fix the tests to +clean up the resources! + + +Multi-threaded Development +--------------------------- +The NetWare version of OpenSSL is thread-safe, however multi-threaded +applications must provide the necessary locking function callbacks. This +is described in doc\threads.doc. The file "openssl-x.x.x\crypto\threads\mttest.c" +is a multi-threaded test program and demonstrates the locking functions. + + +What is openssl2.nlm? +--------------------- +The openssl program has numerous options and can be used for many different +things. Many of the options operate in an interactive mode requiring the +user to enter data. Because of this, a default screen is created for the +program. However, when running the test script it is not desirable to +have a seperate screen. Therefore, the build also creates openssl2.nlm. +Openssl2.nlm is functionally identical but uses the console screen. +Openssl2 can be used when a non-interactive mode is desired. + +NOTE: There are may other possibilities (command line options, etc) +which could have been used to address the screen issue. The openssl2.nlm +option was chosen because it impacted only the build not the code. + + +Why only static libraries? +-------------------------- +Globals, globals, and more globals. The OpenSSL code uses many global +variables that are allocated and initialized when used for the first time. + +On NetWare, most applications (at least historically) run in the kernel. +When running in the kernel, there is one instance of global variables. +For regular application type NLM(s) this isn't a problem because they are +the only ones using the globals. However, for a library NLM (an NLM which +exposes functions and has no threads of execution), the globals cause +problems. Applications could inadvertently step on each other if they +change some globals. Even worse, the first application that triggers a +global to be allocated and initialized has the allocated memory charged to +itself. Now when that application unloads, NetWare will clean up all the +applicaton's memory. The global pointer variables inside OpenSSL now +point to freed memory. An abend waiting to happen! + +To work correctly in the kernel, library NLM(s) that use globals need to +provide a set of globals (instance data) for each application. Another +option is to require the library only be loaded in a protected address +space along with the application using it. + +Modifying the OpenSSL code to provide a set of globals (instance data) for +each application isn't technically difficult, but due to the large number +globals it would require substantial code changes and it wasn't done. Hence, +the build currently only builds static libraries which are then linked +into each application. + +NOTE: If you are building a library NLM that uses the OpenSSL static +libraries, you will still have to deal with the global variable issue. +This is because when you link in the OpenSSL code you bring in all the +globals. One possible solution for the global pointer variables is to +register memory functions with OpenSSL which allocate memory and charge it +to your library NLM (see the function CRYPTO_set_mem_functions). However, +be aware that now all memory allocated by OpenSSL is charged to your NLM. + + +CodeWarrior Tools and W2K +--------------------------- +There have been problems reported with the CodeWarrior Linker +(mwldnlm.exe) in the PDK 2.1 for NetWare when running on Windows 2000. The +problems cause the link step to fail. The only work around is to obtain an +updated linker from Metrowerks. It is expected Metrowerks will release +PDK 3.0 (in beta testing at this time - May, 2001) in the near future which +will fix these problems. + + +Makefile "vclean" +------------------ +The generated makefile has a "vclean" target which cleans up the build +directories. If you have been building successfully and suddenly +experience problems, use "vclean" (gmake -f netware\nlm_xxxx.mak vclean) and retry. + + +"Undefined Symbol" Linker errors +-------------------------------- +There have been linker errors reported when doing a CLIB build. The problems +occur because some versions of the CLIB SDK import files inadvertently +left out some symbols. One symbol in particular is "_lrotl". The missing +functions are actually delivered in the binaries, but they were left out of +the import files. The issues should be fixed in the September 2001 release +of the NDK. If you experience the problems you can temporarily +work around it by manually adding the missing symbols to your version of +"clib.imp". + diff --git a/INSTALL.OS2 b/INSTALL.OS2 new file mode 100644 index 0000000..530316d --- /dev/null +++ b/INSTALL.OS2 @@ -0,0 +1,31 @@ + + Installation on OS/2 + -------------------- + + You need to have the following tools installed: + + * EMX GCC + * PERL + * GNU make + + + To build the makefile, run + + > os2\os2-emx + + This will configure OpenSSL and create OS2-EMX.mak which you then use to + build the OpenSSL libraries & programs by running + + > make -f os2-emx.mak + + If that finishes successfully you will find the libraries and programs in the + "out" directory. + + Alternatively, you can make a dynamic build that puts the library code into + crypto.dll and ssl.dll by running + + > make -f os2-emx-dll.mak + + This will build the above mentioned dlls and a matching pair of import + libraries in the "out_dll" directory along with the set of test programs + and the openssl application. diff --git a/INSTALL.VMS b/INSTALL.VMS new file mode 100644 index 0000000..e5d43a5 --- /dev/null +++ b/INSTALL.VMS @@ -0,0 +1,293 @@ + VMS Installation instructions + written by Richard Levitte + + + +Intro: +====== + +This file is divided in the following parts: + + Requirements - Mandatory reading. + Checking the distribution - Mandatory reading. + Compilation - Mandatory reading. + Logical names - Mandatory reading. + Test - Mandatory reading. + Installation - Mandatory reading. + Backward portability - Read if it's an issue. + Possible bugs or quirks - A few warnings on things that + may go wrong or may surprise you. + TODO - Things that are to come. + + +Requirements: +============= + +To build and install OpenSSL, you will need: + + * DEC C or some other ANSI C compiler.
