If the +argument is the NULL pointer, a pointer to the constant value "NONE" is +returned. + +SSL_CIPHER_get_bits() returns the number of secret bits used for B<cipher>. If +B<alg_bits> is not NULL, it contains the number of bits processed by the +chosen algorithm. If B<cipher> is NULL, 0 is returned. + +SSL_CIPHER_get_version() returns the protocol version for B<cipher>, currently +"SSLv2", "SSLv3", or "TLSv1". If B<cipher> is NULL, "(NONE)" is returned. + +SSL_CIPHER_description() returns a textual description of the cipher used +into the buffer B<buf> of length B<len> provided. B<len> must be at least +128 bytes, otherwise the string "Buffer too small" is returned. If B<buf> +is NULL, a buffer of 128 bytes is allocated using OPENSSL_malloc(). If the +allocation fails, the string "OPENSSL_malloc Error" is returned. + +=head1 NOTES + +The number of bits processed can be different from the secret bits. An +export cipher like e.g. EXP-RC4-MD5 has only 40 secret bits. The algorithm +does use the full 128 bits (which would be returned for B<alg_bits>), of +which however 88bits are fixed. The search space is hence only 40 bits. + +=head1 BUGS + +If SSL_CIPHER_description() is called with B<cipher> being NULL, the +library crashes. + +=head1 RETURN VALUES + +See DESCRIPTION + +=head1 SEE ALSO + +L<ssl(3)|ssl(3)>, L<SSL_get_current_cipher(3)|SSL_get_current_cipher(3)>, +L<SSL_get_ciphers(3)|SSL_get_ciphers(3)> + +=cut |
