It is only available when OpenSSL is complied with the <em>enable-ssl-trace</em> option. Where <em>direction</em> is Sent or Received, <em>version</em> is the protocol version, <em>content_type</em> is the message content type, and <em>data</em> is more info on the message from the <code>SSL_trace</code> API. </dd> <br> <dt> <strong>session</strong> <em>session_id ticket lifetime</em> </dt> <dd> This form of callback is invoked by the OpenSSL function <code>SSL_CTX_sess_set_new_cb()</code>.

The callback should return the password as a string. No arguments are appended to the script upon callback. </dd> <br> <dt><strong>-validatecommand</strong> <em>callback</em></dt> <dd> Invokes the specified <em>callback</em> script during handshake in order to validate the provided value(s). To reject the value and abort connection, the callback should return 0. To accept the value, it should return 1. To reject the value, but continue the connection, it should return 2. <br> <br> <dl> <dt> <strong>alpn</strong> <em>protocol</em> </dt> <dd> For servers, this form of callback is invoked when the client ALPN extension is received.

It is used to select an appropriate certificate to present, and make other configuration adjustments relevant to that server name and its configuration. Called before SNI and ALPN callbacks. </dd> <br> <dt> <strong>sni</strong> <em>servername</em> </dt> <dd> For servers, this form of callback is invoked when the SNI extension from the client is received. Where <em>servername</em> is the client provided server name from the <b>-servername</b> option. This is used when a server supports multiple names, so the right certificate can be used. Called after hello callback but before ALPN callback. </dd> <br> <dt> <strong>verify</strong> <em>channel depth cert status error</em> </dt> <dd> This form of callback is invoked by OpenSSL when a new certificate is received from the peer. It allows the client to check the certificate verification results and choose whether to continue or not. It is called for each certificate in the certificate chain. <ul> <li>The <em>depth</em> argument is an integer representing the current depth on the certificate chain, with <code>0</code> as the peer certificate and higher values going up to the Certificate Authority (CA).</li> <li>The <em>cert</em> argument is a list of key-value pairs similar to those returned by <a href="#tls::status"><strong>tls::status</strong></a>.</li> <li>The <em>status</em> argument is an boolean representing the validity of the current certificate. A value of <code>0</code> means the certificate is deemed invalid.

Note that these are <em>sample</em> implementations only. In a more realistic deployment you would specify your own callback scripts on each TLS channel using the <strong>-command</strong>, <strong>-password</strong>, and <strong>-validate_command</strong> options. </p> <p> The default behavior when the <strong>-command</strong> and <strong>-validate_command</strong> options are not specified is for TLS to process the associated library callbacks internally. The default behavior when the <strong>-password</strong> option is not specified is for TLS to process the associated library callbacks by attempting to call <strong>tls::password</strong>. The difference between these two behaviors is a consequence of maintaining compatibility with earlier implementations. </p> <p> The <strong>tls::debug</strong> variable provides some additional control over these reference callbacks. Its value is zero by default. Higher values produce more diagnostic output, and will also force the verify method in <strong>tls::callback</strong> to accept the certificate, even when it is invalid. </p> <p> <em> The use of the reference callbacks <strong>tls::callback</strong>, <strong>tls::password</strong>, and <strong>tls::validate_command</strong> is not recommended. They may be removed from future releases. </em> </p> <p> <em> The use of the variable <strong>tls::debug</strong> is not recommended. It may be removed from future releases. </em> </p> <h3><a name="DEBUG">DEBUG</a></h3> TLS key logging can be enabled by setting the environment variable <b>SSLKEYLOGFILE</b> to the name of the file to log to. Then whenever TLS key material is generated or received it will be logged to the file. This is useful for logging key data for network logging tools to use to decrypt the data. <h3><a name="HTTPS EXAMPLE">HTTPS EXAMPLE</a></h3> <p>This example uses a sample server.pem provided with the TLS release, courtesy of the <strong>OpenSSL</strong> project.</p> <pre><code> package require http package require tls http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs] set tok [http::geturl https://www.tcl.tk/] </code></pre> <h3><a name="SPECIAL CONSIDERATIONS">SPECIAL CONSIDERATIONS</a></h3> <p>The capabilities of this package can vary enormously based upon how your OpenSSL library was configured and built. New versions may obsolete older protocol versions, add or remove ciphers, change default values, etc. Use the <strong>tls::ciphers</strong> and <strong>tls::protocols</strong> commands to obtain the supported versions.</p> <h3><a name="SEE ALSO">SEE ALSO</a></h3> <p><strong>socket</strong>, <strong>fileevent, </strong><a href="http://www.openssl.org/"><strong>OpenSSL</strong></a></p> <hr> |
