Tool Command Language (TCL) Transport Layer Security (TLS) Extension
Intro
=====
This package provides an extension which implements Secure Socket Layer (SSL)
and Transport Layer Security (TLS) encryption over Transmission Control
Protocol (TCP) network communication channels. It utilizes the OpenSSL library.
Protocol (TCP) network communication channels utilizing the OpenSSL library.
Description

This extension works by creating a layered TCL Channel on top of an existing
bi-directional channel created by the TLS socket command. All existing socket
functionality is supported, in addition to several new options. Both client
and server modes are supported.
