+NRPE With SSL/TLS
+
+NRPE now has the option for Encrypting Network traffic using
+SSL/TLS from openssl. 
+
+The Encryption is done using a set encryption routine of 
+AES-256 Bit Encryption using SHA and Anon-DH. This encrypts
+all traffic using the NRPE sockets from the client to the server.
+
+Since we are using Anon-DH this allows for an encrypted 
+SSL/TLS Connection without using pre-generated keys or 
+certificates. The key generation information used by the 
+program to dynaically create keys on daemon startup can be found
+in the dh.h file in the nrpe src directory. This file was created
+using the command:
+
+openssl dhparam -C 512 
+
+which outputs the C code in dh.h. For your own security you can replace
+that file with your own dhparam generated code.
+
+As of this time you will need to have the latest greatest version of
+OpenSSL (tested against version 0.9.7a) since not all versions have
+the AES algorythm in them.
+
+I am not aware that at this time this code is restricted under export 
+restrictions but I leave that verification process up to you.
+
+Thoughts and suggestions are welcome and I can be reached on the
+Nagios and NagiosPlug Mailing Lists.
