NAME
SSL_SESSION_get0_cipher, SSL_SESSION_set_cipher - set and retrieve the SSL cipher associated with a session
SYNOPSIS
#include <openssl/ssl.h>
const SSL_CIPHER *SSL_SESSION_get0_cipher(const SSL_SESSION *s);
int SSL_SESSION_set_cipher(SSL_SESSION *s, const SSL_CIPHER *cipher);
DESCRIPTION
SSL_SESSION_get0_cipher() retrieves the cipher that was used by the
connection when the session was created, or
NULL if it cannot be determined.
The value returned is a pointer to an object maintained within s and
should not be released.
SSL_SESSION_set_cipher() can be used to set the ciphersuite associated with the
SSL_SESSION s to cipher. For example, this could be used to set up a
session based PSK (see SSL_CTX_set_psk_use_session_callback(3)).
RETURN VALUES
SSL_SESSION_get0_cipher() returns the
SSL_CIPHER associated with the
SSL_SESSION
or
NULL if it cannot be determined.
SSL_SESSION_set_cipher() returns 1 on success or 0 on failure.
