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.
