NAME

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

SYNOPSIS

#include <openssl/ssl.h>
SSL_CIPHER ∗SSL_get_current_cipher(
        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))

DESCRIPTION

The SSL_get_current_cipher() function returns a pointer to an SSL_CIPHER object containing the description of the actually used cipher of a connection established with the ssl object. 

The SSL_get_cipher() and SSL_get_cipher_name() macros obtain the name of the currently used cipher. The SSL_get_cipher_bits() macro obtains the number of secret/algorithm bits used and  the SSL_get_cipher_version() function returns the protocol name. See SSL_CIPHER_get_name(3) for more details. 

RETURN VALUES

The SSL_get_current_cipher() function returns the cipher actually used or NULL, when no session has been established.
