SSL_GET_CURRENT_CIPHER(3)  Library Functions Manual  SSL_GET_CURRENT_CIPHER(3)

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>

     const SSL_CIPHER *
     SSL_get_current_cipher(const SSL *ssl);

     const char *
     SSL_get_cipher(const SSL *ssl);

     const char *
     SSL_get_cipher_name(const SSL *ssl);

     int
     SSL_get_cipher_bits(const SSL *ssl, int *np);

     char *
     SSL_get_cipher_version(const SSL *ssl);

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 ssl object.  See SSL_CIPHER_get_name(3) for more
     details.

     SSL_get_cipher_name() obtains the name of the currently used cipher.
     SSL_get_cipher() is identical to SSL_get_cipher_name().

     SSL_get_cipher_bits() obtains the number of secret/algorithm bits used
     and SSL_get_cipher_version() returns the protocol name.

     SSL_get_cipher(), SSL_get_cipher_name(), SSL_get_cipher_bits(), and
     SSL_get_cipher_version() are implemented as macros.

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