*
* The SSL/TLS communication module provides the means to create an SSL/TLS
* communication channel.
* The basic provisions are:
* - initialise an SSL/TLS context (see \c ssl_init()).
* - perform an SSL/TLS handshake (see \c ssl_handshake()).
* - read/write (see \c ssl_read() and \c ssl_write()).
* - notify a peer that conection is being closed (see \c ssl_close_notify()).
*
*
* Many aspects of such a channel are set through parameters and callback
* functions:
* - the endpoint role: client or server.
* - the authentication mode. Should verification take place.
* - the Host-to-host communication channel. A TCP/IP module is provided.
* - the random number generator (RNG).
* - the ciphers to use for encryption/decryption.
* - session control functions.
* - X.509 parameters for certificate-handling and key exchange.
*
*
* This module can be used to create an SSL/TLS server and client and to provide a basic
* framework to setup and communicate through an SSL/TLS communication channel.\n
* Note that you need to provide for several aspects yourself as mentioned above.
