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
software library.
Version 1.9 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
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.
Documentation
=============
See the doc directory for the full usage documentation.
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/
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
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

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.
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.
Documentation
=============
See the doc directory for the full usage documentation.
Compatibility
=============
This package requires TCL 8.5 or later. It will work with TCL 9. If this
extension is built against TCL 8.x it will not work with TCL 9 or vice versa.
It is best to compile both separately then install them with the compatible
TCL versions.
This package is compatible with:
- OpenSSL v1.1.1 or later though 3.2+ is preferred. See (http://www.openssl.org/
Note: There are incompatibilities between OpenSSL 1.1.1 and 3.x, so if this
extension is built against OpenSSL 1.1.1 it will not work with an OpenSSL 3.x
installation or vice versa.
Installation
============
This package uses the TCL Extension Architecture (TEA) to build and install on
any supported Unix, Mac, or MS Windows system. It depends on the OpenSSL
libraries being available prior to building the TCLTLS extension.
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

$ make install
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
-----
The CURL team makes them available at https://curl.se/docs/caextract.html.
Look for the cacert.pem file.

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