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 for more details.
SSL_get_current_cipher() returns the cipher actually used or NULL, when
no session has been established.
