libressl-SSL_get_current_cipher3
Get ssl_cipher of a connection
Usage
SSL Library (libssl, -lssl) libcrypto
#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);
Overview
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.
