=head1 NAME
openssl-ciphers,
ciphers - SSL cipher display and cipher list tool.
=head1 SYNOPSIS
B<openssl> B<ciphers>
[B<-v>]
[B<-V>]
[B<-ssl2>]
[B<-ssl3>]
[B<-tls1>]
[B<cipherlist>]
=head1 DESCRIPTION
The B<ciphers> command converts textual OpenSSL cipher lists into ordered
SSL cipher preference lists. It can be used as a test tool to determine
the appropriate cipherlist.
=head1 COMMAND OPTIONS
=over 4
=item B<-v>
Verbose option. List ciphers with a complete description of
protocol version (SSLv2 or SSLv3; the latter includes TLS), key exchange,
authentication, encryption and mac algorithms used along with any key size
restrictions and whether the algorithm is classed as an "export" cipher.
Note that without the B<-v> option, ciphers may seem to appear twice
in a cipher list; this is when similar ciphers are available for
SSL v2 and for SSL v3/TLS v1.
=item B<-V>
Like B<-v>, but include cipher suite codes in output (hex format).
=item B<-ssl3>, B<-tls1>
This lists ciphers compatible with any of SSLv3, TLSv1, TLSv1.1 or TLSv1.2.
=item B<-ssl2>
Only include SSLv2 ciphers.
=item B<-h>, B<-?>
Print a brief usage message.
=item B<cipherlist>
A cipher list to convert to a cipher preference list. If it is not included
then the default cipher list will be used. The format is described below.
=back
=head1 CIPHER LIST FORMAT
The cipher list consists of one or more I<cipher strings> separated by colons.
Commas or spaces are also acceptable separators but colons are normally used.
The actual cipher string can take several different forms.
It can consist of a single cipher suite such as B<RC4-SHA>.
It can represent a list of cipher suites containing a certain algorithm, or
cipher suites of a certain type. For example B<SHA1> represents all ciphers
suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
algorithms.
Lists of cipher suites can be combined in a single cipher string using the
B<+> character. This is used as a logical B<and> operation. For example
B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
algorithms.
Each cipher string can be optionally preceded by the characters B<!>,
B<-> or B<+>.
If B<!> is used then the ciphers are permanently deleted from the list.
The ciphers deleted can never reappear in the list even if they are
explicitly stated.
If B<-> is used then the ciphers are deleted from the list, but some or
all of the ciphers can be added again by later options.
If B<+> is used then the ciphers are moved to the end of the list. This
option doesn't add any new ciphers it just moves matching existing ones.
If none of these characters is present then the string is just interpreted
as a list of ciphers to be appended to the current preference list. If the
list includes any ciphers already present they will be ignored: that is they
will not moved to the end of the list.
Additionally the cipher string B<@STRENGTH> can be used at any point to sort
the current cipher list in order of encryption algorithm key length.
=head1 CIPHER STRINGS
The following is a list of all permitted cipher strings and their meanings.
=over 4
=item B<DEFAULT>
The default cipher list.
This is determined at compile time and is normally
B<ALL:!EXPORT:!LOW:!aNULL:!eNULL:!SSLv2>.
When used, this must be the first cipherstring specified.
=item B<COMPLEMENTOFDEFAULT>
the ciphers included in B<ALL>, but not enabled by default. Currently
this is B<ADH> and B<AECDH>. Note that this rule does not cover B<eNULL>,
which is not included by B<ALL> (use B<COMPLEMENTOFALL> if necessary).
=item B<ALL>
all cipher suites except the B<eNULL> ciphers which must be explicitly enabled;
as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default
=item B<COMPLEMENTOFALL>
the cipher suites not enabled by B<ALL>, currently being B<eNULL>.
=item B<HIGH>
"high" encryption cipher suites. This currently means those with key lengths larger
than 128 bits, and some cipher suites with 128-bit keys.
=item B<MEDIUM>
"medium" encryption cipher suites, currently some of those using 128 bit encryption.
=item B<LOW>
Low strength encryption cipher suites, currently those using 64 or 56 bit
encryption algorithms but excluding export cipher suites.
As of OpenSSL 1.0.2g, these are disabled in default builds.
=item B<EXP>, B<EXPORT>
Export strength encryption algorithms. Including 40 and 56 bits algorithms.
As of OpenSSL 1.0.2g, these are disabled in default builds.
=item B<EXPORT40>
40-bit export encryption algorithms
As of OpenSSL 1.0.2g, these are disabled in default builds.
=item B<EXPORT56>
56-bit export encryption algorithms. In OpenSSL 0.9.8c and later the set of
56 bit export ciphers is empty unless OpenSSL has been explicitly configured
with support for experimental ciphers.
As of OpenSSL 1.0.2g, these are disabled in default builds.
=item B<eNULL>, B<NULL>
The "NULL" ciphers that is those offering no encryption. Because these offer no
encryption at all and are a security risk they are not enabled via either the
B<DEFAULT> or B<ALL> cipher strings.
Be careful when building cipherlists out of lower-level primitives such as
B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers.
When in doubt, include B<!eNULL> in your cipherlist.
=item B<aNULL>
The cipher suites offering no authentication. This is currently the anonymous
DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
to a "man in the middle" attack and so their use is normally discouraged.
These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL>
ciphers.
Be careful when building cipherlists out of lower-level primitives such as
B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers.
When in doubt, include B<!aNULL> in your cipherlist.
=item B<kRSA>, B<RSA>
cipher suites using RSA key exchange or authentication. B<RSA> is an alias for
B<kRSA>.
=item B<kDHr>, B<kDHd>, B<kDH>

Curve DH (ECDH) cipher suites.
=item B<DH>
cipher suites using DH, including anonymous DH, ephemeral DH and fixed DH.
=item B<kECDHr>, B<kECDHe>, B<kECDH>

keys or either respectively.
=item B<kECDHE>, B<kEECDH>
cipher suites using ephemeral ECDH key agreement, including anonymous
cipher suites.
=item B<ECDHE>, B<EECDH>

fixed ECDH.
=item B<aRSA>

=item B<aDSS>, B<DSS>
cipher suites using DSS authentication, i.e. the certificates carry DSS keys.
=item B<aDH>
cipher suites effectively using DH authentication, i.e. the certificates carry
DH keys.
=item B<aECDH>
cipher suites effectively using ECDH authentication, i.e. the certificates
carry ECDH keys.
=item B<aECDSA>, B<ECDSA>
cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA
keys.
=item B<kFZA>, B<aFZA>, B<eFZA>, B<FZA>
ciphers suites using FORTEZZA key exchange, authentication, encryption or all
FORTEZZA algorithms. Not implemented.
=item B<TLSv1.2>, B<TLSv1>, B<SSLv3>, B<SSLv2>
TLS v1.2, TLS v1.0, SSL v3.0 or SSL v2.0 cipher suites respectively. Note:
there are no ciphersuites specific to TLS v1.1.
=item B<AES128>, B<AES256>, B<AES>
cipher suites using 128 bit AES, 256 bit AES or either 128 or 256 bit AES.
=item B<AESGCM>
AES in Galois Counter Mode (GCM): these ciphersuites are only supported
in TLS v1.2.
=item B<CAMELLIA128>, B<CAMELLIA256>, B<CAMELLIA>
cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either 128 or 256 bit
CAMELLIA.
=item B<3DES>

standard has been expired so use GOST R 34.10-2001)
=item B<kGOST>
cipher suites, using VKO 34.10 key exchange, specified in the RFC 4357.
=item B<GOST94>

=item B<SUITEB128>, B<SUITEB128ONLY>, B<SUITEB192>
enables suite B mode operation using 128 (permitting 192 bit mode by peer)
128 bit (not permitting 192 bit by peer) or 192 bit level of security
respectively. If used these cipherstrings should appear first in the cipher
list and anything after them is ignored. Setting Suite B mode has additional
consequences required to comply with RFC6460. In particular the supported
signature algorithms is reduced to support only ECDSA and SHA256 or SHA384,
only the elliptic curves P-256 and P-384 can be used and only the two suite B
compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.

=head1 CIPHER SUITE NAMES
The following lists give the SSL or TLS cipher suites names from the
relevant specification and their OpenSSL equivalents. It should be noted,
that several cipher suite names do not include the authentication used,
e.g. DES-CBC3-SHA. In these cases, RSA authentication is used.

=head1 NOTES
Some compiled versions of OpenSSL may not include all the ciphers
listed here because some ciphers were excluded at compile time.
=head1 EXAMPLES
Verbose listing of all OpenSSL ciphers including NULL ciphers:
openssl ciphers -v 'ALL:eNULL'
Include all ciphers except NULL and anonymous DH then sort by
strength:
openssl ciphers -v 'ALL:!ADH:@STRENGTH'
Include all ciphers except ones with no encryption (eNULL) or no
authentication (aNULL):
openssl ciphers -v 'ALL:!aNULL'
Include only 3DES ciphers and then place RSA ciphers last:
openssl ciphers -v '3DES:+RSA'
Include all RC4 ciphers but leave out those without authentication:
openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
Include all chiphers with RSA authentication but leave out ciphers without
encryption.
openssl ciphers -v 'RSA:!COMPLEMENTOFALL'

=head1 HISTORY
The B<COMPLENTOFALL> and B<COMPLEMENTOFDEFAULT> selection options
for cipherlist strings were added in OpenSSL 0.9.7.
The B<-V> option for the B<ciphers> command was added in OpenSSL 1.0.0.
