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) over Transmission Control Protocol (TCP)
network communication channels. It utilizes either the OpenSSL or LibreSSL
software library.
Version 2.0 also provides a cryptography library providing TCL scripts access
to the crypto capabilities of the OpenSSL library.
Description
===========
This extension works by creating a layered TCL Channel on top of an existing

The supported configure options include all of the standard TEA configure script
options, plus:
--disable-tls1 disable TLS1 protocol
--disable-tls1_1 disable TLS1.1 protocol
--disable-tls1_2 disable TLS1.2 protocol
--disable-tls1_3 disable TLS1.3 protocol
--enable-deterministic enable deterministic DH parameters
--with-builtin-dh-params-size=<bits> specify the size of the built-in, precomputed, DH params

--disable-tls1_1 disable TLS1.1 protocol
--disable-tls1_2 disable TLS1.2 protocol
--disable-tls1_3 disable TLS1.3 protocol
--enable-ssl-fastpath enable using the underlying file descriptor for talking directly to the SSL library
--enable-hardening enable hardening attempts
--enable-static-ssl enable static linking to the SSL library
If either TCL or OpenSSL are installed in non-standard locations, the following
configure options are available. For all options, see ./configure --help.
--with-tcl=<dir> path to where tclCondig.sh file resides
--with-tclinclude=<dir> directory containing the public Tcl header files
--with-openssl-dir=<dir> path to root directory of OpenSSL or LibreSSL installation
