If the argument is the \s-1NULL\s0 pointer, a pointer to the constant value \*(L"\s-1NONE\*(R"\s0 is returned. .PP \&\fBSSL_CIPHER_get_bits()\fR returns the number of secret bits used for \fBcipher\fR. If \&\fBalg_bits\fR is not \s-1NULL,\s0 it contains the number of bits processed by the chosen algorithm. If \fBcipher\fR is \s-1NULL, 0\s0 is returned. .PP \&\fBSSL_CIPHER_get_version()\fR returns string which indicates the \s-1SSL/TLS\s0 protocol version that first defined the cipher. This is currently \fBSSLv2\fR or \fBTLSv1/SSLv3\fR. In some cases it should possibly return \*(L"TLSv1.2\*(R" but does not; use \fBSSL_CIPHER_description()\fR instead. If \fBcipher\fR is \s-1NULL, \*(L"\s0(\s-1NONE\s0)\*(R" is returned. .PP \&\fBSSL_CIPHER_description()\fR returns a textual description of the cipher used into the buffer \fBbuf\fR of length \fBlen\fR provided. \fBlen\fR must be at least 128 bytes, otherwise a pointer to the string \*(L"Buffer too small\*(R" is returned. If \fBbuf\fR is \s-1NULL,\s0 a buffer of 128 bytes is allocated using \&\fBOPENSSL_malloc()\fR. If the allocation fails, a pointer to the string \&\*(L"OPENSSL_malloc Error\*(R" is returned. .SH "NOTES" .IX Header "NOTES" The number of bits processed can be different from the secret bits. An export cipher like e.g. \s-1EXP\-RC4\-MD5\s0 has only 40 secret bits. The algorithm does use the full 128 bits (which would be returned for \fBalg_bits\fR), of which however 88bits are fixed. The search space is hence only 40 bits. .PP The string returned by \fBSSL_CIPHER_description()\fR in case of success consists of cleartext information separated by one or more blanks in the following sequence: .IP "<ciphername>" 4 .IX Item "<ciphername>" Textual representation of the cipher name. .IP "<protocol version>" 4 .IX Item "<protocol version>" Protocol version: \fBSSLv2\fR, \fBSSLv3\fR, \fBTLSv1.2\fR. The TLSv1.0 ciphers are flagged with SSLv3.

This case should not occur. .PP The standard terminology for ephemeral Diffie-Hellman schemes is \s-1DHE\s0 (finite field) or \s-1ECDHE\s0 (elliptic curve). This version of OpenSSL idiosyncratically reports these schemes as \s-1EDH\s0 and \s-1EECDH,\s0 even though it also accepts the standard terminology. .PP It is recommended to use the standard terminology (\s-1DHE\s0 and \s-1ECDHE\s0) during configuration (e.g. via SSL_CTX_set_cipher_list) for clarity of configuration. OpenSSL versions after 1.0.2 will report the standard terms via SSL_CIPHER_get_name and SSL_CIPHER_description. .SH "RETURN VALUES" .IX Header "RETURN VALUES" See \s-1DESCRIPTION\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(3), \fBSSL_get_current_cipher\fR\|(3), \&\fBSSL_get_ciphers\fR\|(3), \fBciphers\fR\|(1), \&\fBSSL_CTX_set_cipher_list\fR\|(3)
