    <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

    <dd>Returns the current security status of an SSL channel. The

        connected peer. If the result is an empty list then the
        SSL handshake has not yet completed.
