<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>SSL_CTX_set_keylog_callback()</code> sets the TLS key logging callback. This callback
|
|
is called whenever TLS key material is generated or received, in order to allow
|
|
applications to store this keying material for debugging purposes.</p>
|
|
<p><code>SSL_CTX_get_keylog_callback()</code> retrieves the previously set TLS key logging
|
|
callback. If no callback has been set, this will return NULL. When there is no
|
|
key logging callback, or if SSL_CTX_set_keylog_callback is called with NULL as
|
|
the value of cb, no logging of key material will be done.</p>
|
|
<p>The key logging callback is called with two items: the <strong>ssl</strong> object associated
|
|
with the connection, and <strong>line</strong>, a string containing the key material in the
|
|
format used by NSS for its <strong>SSLKEYLOGFILE</strong> debugging output. To recreate that
|
|
file, the key logging callback should log <strong>line</strong>, followed by a newline.
|
|
<strong>line</strong> will always be a NULL-terminated string.</p>

<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p><code>SSL_CTX_get_keylog_callback()</code> returns a pointer to <strong>SSL_CTX_keylog_cb_func</strong> or
|
|
NULL if the callback is not set.</p>
