<p>This extension provides a generic binding to <a

href="http://www.openssl.org/">OpenSSL</a>, utilizing the
href="http://www.oche.de/~akupries/soft/trf/index.html">Trf</a>
Channel Stacking patch for Tcl 8.[01] and the new <strong>Tcl_StackChannel</strong>
command with additional options for controlling the SSL session.</p>
command with additional options for controlling the SSL session.
To use TLS with an earlier version of Tcl than 8.2, please obtain
TLS v1.3. Please note that there are known limitations with the
stacked channel implementation prior to 8.3.2, so it is recommended
that TLS is used with an 8.3.2+ interpreter. TLS v1.4 will work
with 8.2+, it is just more stable with 8.3.2+.
</p>
<h3><a name="COMMANDS">COMMANDS</a></h3>
<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>
