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


 #include <openssl/ssl.h>

 SSL_CIPHER *SSL_get_current_cipher(const SSL *ssl);
 #define SSL_get_cipher(s) \
 #define SSL_get_cipher_name(s) \
 #define SSL_get_cipher_bits(s,np) \
 #define SSL_get_cipher_version(s) \


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 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 SSL_CIPHER_get_name(3) for more details.

Return Values

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