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
network communication channels. It utilizes either the OpenSSL
software library.
Version 1.9 also provides a cryptography library providing TCL scripts access
to the crypto capabilities of the OpenSSL library.

Compatibility
=============
This package requires TCL 8.5 or later.
This package is compatible with:
- OpenSSL v1.1.1 or later. See (http://www.openssl.org/
- LibreSSL (TBD version)
Installation
============
This package uses the Tcl Extension Architecture (TEA) to build and install on
any supported Unix, Mac, or MS Windows system. Either the OpenSSL or LibreSSL
any supported Unix, Mac, or MS Windows system. Either the OpenSSL
software libraries must be built and available prior to building TCL TLS.
UNIX and Linux
--------------
The standard TEA config, make and install process is supported.
$ cd tcltls
$ ./configure --enable-64bit
$ make
$ make test
$ make install
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-debug enable debugging mode and output more status
--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
--with-openssl-includedir=<dir> path to include directory of OpenSSL or LibreSSL installation
--with-openssl-libdir=<dir> path to lib directory of OpenSSL or LibreSSL installation
--with-openssl-pkgconfig=<dir> path to root directory of OpenSSL or LibreSSL pkgconfigdir
--with-openssl-dir=<dir> path to root directory of OpenSSL installation
--with-openssl-includedir=<dir> path to include directory of OpenSSL installation
--with-openssl-libdir=<dir> path to lib directory of OpenSSL installation
--with-openssl-pkgconfig=<dir> path to root directory of OpenSSL pkg-config directory
MacOS
-----
The standard TEA installation process is supported. Use the --with-tcl option
to set the TCL path if the ActiveState or other non-Apple version of TCL is to

Windows
-------
If installing with MinGW, use the TEA build process. If using MS Visual C
(MSVC), see the win/README.txt file for the installation instructions.
Other
-----
If OpenSSL is not installed on the system, the Certificate Authority (CA)
provided certificates must be downloaded and installed with the software.
The CURL team makes them available at https://curl.se/docs/caextract.html.
Look for the cacert.pem file.
