DESCRIPTION
SSL_get_current_cipher() returns a pointer to an SSL_CIPHER
object containing the description of the actually used cipher of
a connection established with the ssl object. 
SSL_get_cipher() and SSL_get_cipher_name() are identical macros
to obtain the name of the currently used cipher. SSL_get_cipher_bits()
is a macro to obtain the number of secret/algorithm bits used and SSL_get_cipher_version()
returns the protocol name. See SSL_CIPHER_get_name(3) for more details. 
RETURN VALUES
SSL_get_current_cipher() returns the cipher actually used
or NULL, when no session has been established.
