This value should be a version constant such as <b>TLS1_3_VERSION</b> etc. For example, this could be used to set up a session based PSK (see <a href="../man3/SSL_CTX_set_psk_use_session_callback.html">SSL_CTX_set_psk_use_session_callback(3)</a>).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_SESSION_get_protocol_version() returns a number indicating the protocol version used for the session; this number matches the constants <i>e.g.</i> <b>TLS1_VERSION</b>, <b>TLS1_2_VERSION</b> or <b>TLS1_3_VERSION</b>.</p> <p>Note that the SSL_SESSION_get_protocol_version() function does <b>not</b> perform a null check on the provided session <b>s</b> pointer.</p> <p>SSL_SESSION_set_protocol_version() returns 1 on success or 0 on failure.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_CTX_set_psk_use_session_callback.html">SSL_CTX_set_psk_use_session_callback(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The SSL_SESSION_get_protocol_version() function was added in OpenSSL 1.1.0.
