NAME

6       SSL_SESSION_get0_cipher, SSL_SESSION_set_cipher - set and retrieve the
7       SSL cipher associated with a session
8

SYNOPSIS

10        #include <openssl/ssl.h>
11
12        const SSL_CIPHER *SSL_SESSION_get0_cipher(const SSL_SESSION *s);
13        int SSL_SESSION_set_cipher(SSL_SESSION *s, const SSL_CIPHER *cipher);
14

DESCRIPTION

16       SSL_SESSION_get0_cipher() retrieves the cipher that was used by the
17       connection when the session was created, or NULL if it cannot be
18       determined.
19
20       The value returned is a pointer to an object maintained within s and
21       should not be released.
22
23       SSL_SESSION_set_cipher() can be used to set the ciphersuite associated
24       with the SSL_SESSION s to cipher. For example, this could be used to
25       set up a session based PSK (see
26       SSL_CTX_set_psk_use_session_callback(3)).
27

RETURN VALUES

29       SSL_SESSION_get0_cipher() returns the SSL_CIPHER associated with the
30       SSL_SESSION or NULL if it cannot be determined.
31
32       SSL_SESSION_set_cipher() returns 1 on success or 0 on failure.
