<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p>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.</p>
|
|
<p>The value returned is a pointer to an object maintained within <strong>s</strong> and
|
|
should not be released.</p>
|
|
<p><code>SSL_SESSION_set_cipher()</code> can be used to set the ciphersuite associated with the
|
|
SSL_SESSION <strong>s</strong> to <strong>cipher</strong>. For example, this could be used to set up a
|
|
session based PSK (see <em>SSL_CTX_set_psk_use_session_callback(3)</em>).</p>

<p>SSL_SESSION_get0_cipher() returns the SSL_CIPHER associated with the SSL_SESSION

<p><code>SSL_SESSION_set_cipher()</code> returns 1 on success or 0 on failure.</p>
