| |
| SSL_get_current_cipher, SSL_get_cipher, SSL_get_cipher_name, |
| SSL_get_cipher_bits, SSL_get_cipher_version - get SSL_CIPHER of a connection |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/ssl.h> |
| |
| SSL_CIPHER *SSL_get_current_cipher(const SSL *ssl); |
| #define SSL_get_cipher(s) \ |
| SSL_CIPHER_get_name(SSL_get_current_cipher(s)) |
| #define SSL_get_cipher_name(s) \ |
| SSL_CIPHER_get_name(SSL_get_current_cipher(s)) |
| #define SSL_get_cipher_bits(s,np) \ |
| SSL_CIPHER_get_bits(SSL_get_current_cipher(s),np) |
| #define SSL_get_cipher_version(s) \ |
| SSL_CIPHER_get_version(SSL_get_current_cipher(s)) |
| |
| =head1 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 B<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 L<SSL_CIPHER_get_name(3)|SSL_CIPHER_get_name(3)> for more details. |
| |
| =head1 RETURN VALUES |
| |
| SSL_get_current_cipher() returns the cipher actually used or NULL, when |
| no session has been established. |
