     SSL_CIPHER_get_name() returns a pointer to the name of
     cccciiiipppphhhheeeerrrr. 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 cccciiiipppphhhheeeerrrr. If aaaallllgggg_bbbbiiiittttssss is not NULL, it contains the number
     of bits processed by the chosen algorithm. If cccciiiipppphhhheeeerrrr is
     NULL, 0 is returned.

     SSL_CIPHER_get_version() returns the protocol version for
     cccciiiipppphhhheeeerrrr, currently "SSLv2", "SSLv3", or "TLSv1". If cccciiiipppphhhheeeerrrr is
     NULL, "(NONE)" is returned.

     SSL_CIPHER_description() returns a textual description of
     the cipher used into the buffer bbbbuuuuffff of length lllleeeennnn provided.
     lllleeeennnn must be at least 128 bytes, otherwise a pointer to the
     string "Buffer too small" is returned. If bbbbuuuuffff is NULL, a
     buffer of 128 bytes is allocated using OPENSSL_malloc(). If
     the allocation fails, a pointer to the string
     "OPENSSL_malloc Error" is returned.

NNNNOOOOTTTTEEEESSSS
     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 aaaallllgggg_bbbbiiiittttssss), of which however
     88bits are fixed. The search space is hence only 40 bits.

     The string returned by SSL_CIPHER_description() in case of
     success consists of cleartext information separated by one
     or more blanks in the following sequence:

     If SSL_CIPHER_description() is called with cccciiiipppphhhheeeerrrr being
     NULL, the library crashes.

     If SSL_CIPHER_description() cannot handle a built-in cipher,
     the according description of the cipher property is uuuunnnnkkkknnnnoooowwwwnnnn.
     This case should not occur.
