<p>Typically one would use the <strong>tls::socket </strong>command
which provides compatibility with the native Tcl <strong>socket</strong>
command. In such cases <strong>tls::import</strong> should not be
used directly.</p>

<dl>
    <dt><a name="tls::init"><b>tls::init </b><i>?options?</i></a></dt>
    <dd>This routine sets the default options used by <strong>tls::socket</strong>
        and is <em>optional</em>. If you call <strong>tls::import</strong>
        directly this routine has no effect. Any of the options
        that <strong>tls::socket</strong> accepts can be set
        using this command, though you should limit your options
        to only TLS related ones.</dd>

    <dt><b>tls::socket</b><em> ?-server command? ?options? port</em></dt>
    <dd>This is a helper function that utilizes the underlying
        commands (<strong>tls::import</strong>). It behaves
        exactly the same as the native Tcl <strong>socket</strong>
        command except that the options can include any of the
        applicable <a href="#tls::import"><strong>tls:import</strong></a>
        options with one additional option:
<blockquote>

</blockquote>








































































































    <dt>&nbsp;</dt>
    <dt><a name="tls::handshake"><strong>tls::handshake</strong> <em>channel</em></a></dt>
    <dd>Forces handshake to take place, and returns 0 if
        handshake is still in progress (non-blocking), or 1 if
        the handshake was successful. If the handshake failed
        this routine will throw an error.</dd>
    <dt>&nbsp;</dt>
    <dt><a name="tls::status"><strong>tls::status</strong>
    <em>?-local? channel</em></a></dt>
    <dd>Returns the current security status of an SSL channel. The
        result is a list of key-value pairs describing the
        connected peer. If the result is an empty list then the
        SSL handshake has not yet completed.
        If <em>-local</em> is given, then the certificate information
