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.

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
  --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
  --with-builtin-dh-params-size=<bits>	specify the size of the built-in, precomputed, DH params

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
