	compiling with 8.2.  Now compiles with 8.2+ and tested to work
	with 8.2+ and dynamically adjust to the version of Tcl it was
	loaded into.  TLS will fail the test suite with Tcl 8.2-8.3.1.

	* tests/all.tcl: added catch around ::tcltest::normalizePath
	because it doesn't exist in pre-8.3 tcltest.

	* tests/simpleClient.tcl: 
	* tests/simpleClient.tcl:
	* tests/simpleServer.tcl: added simple client/server test scripts
	that use test certs and can do simple stress tests.

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
and Transport Layer Security (TLS) encryption over Transmission Control
Protocol (TCP) network communication channels utilizing the OpenSSL library.
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.
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
=============

TCL
---

This package requires TCL 8.5 or later.
This package requires TCL 8.5 or later. It will also work with TCL 9, but it is
not binary compatible between major TCL versions. This means if this extension
is built with TCL 8.x it will not load into TCL 9 or vice versa. It is best
to compile both separately then install them with the compatible TCL versions.

OpenSSL
-------

This package is compatible with:
- OpenSSL v1.1.1 or later. See (http://www.openssl.org/
- LibreSSL (TBD version)
This package is compatible with OpenSSL v1.1.1 or later, though 3.2 or later is
preferred. See http://www.openssl.org/. Please note that there are a few API
incompatibilities between OpenSSL 1.1.1 and 3.x, so if this extension is built
against OpenSSL 1.1.1 it is not binary compatible with OpenSSL 3.x or vice
versa.

TCLTLS
------

There were several changes made in the callback command arguments between
versions 1.7 and 2.0. See the doc/tls.html for what changed and library/tls.tcl
for example handler functions that are backwards compatible.


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
software libraries must be built and available prior to building TCL TLS.
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.
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:
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
be used.

	$ cd tcltls
	$ ./configure --with-tcl=/Library/Frameworks/Tcl.framework/
	$ make
	$ make test
	$ make install


Windows
-------

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.
(MSVC), see the win/README.txt file for the 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.

\`configure' configures tls 1.8.0 to adapt to many kinds of systems.
'configure' configures tls 1.8.0 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
  -q, --quiet, --silent   do not print 'checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -C, --config-cache      alias for '--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
      --srcdir=DIR        find the sources in DIR [configure dir or '..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]

dnl	This file is an input file used by the GNU "autoconf" program to
dnl	generate the file "configure", which is run during Tcl installation
dnl	to configure the system for the local environment.

#
#-----------------------------------------------------------------------
# This is the configure.ac for the TclTLS extension.  The only places you
# should need to modify this file are marked by the string __CHANGE__.
#-----------------------------------------------------------------------

#-----------------------------------------------------------------------
# Set your package name and version numbers here.
#
# This initializes the environment with PACKAGE_NAME and PACKAGE_VERSION
# set as provided.  These will also be added as -D defs in your Makefile
# so you can encode the package version directly into the source files.
# This will also define a special symbol for Windows (BUILD_<PACKAGE_NAME>
# so that we create the export library with the dll.

<p>This extension provides TCL script access to secure socket communications
using the Transport Layer Security (TLS) protocol. It provides a generic
binding to <a href="http://www.openssl.org/">OpenSSL</a>, utilizing the
<strong>Tcl_StackChannel</strong> API in Tcl 8.4 and higher.

<h3><a name="CERTIFICATE VALIDATION">CERTIFICATE VALIDATION</a></h3>

<h4>Summary of command line options:</h4>
<p>The following options are used for certificate validation:</p>
<ul>
<li>The <b>-cadir</b> option specifies the directory where the Certificate
Authority (CA) certificates are stored. The default is platform specific, but
is usually "/etc/ssl/certs" on Linux/Unix systems. The default location can be
overridden via the <b>SSL_CERT_DIR</b> environment variable.</li>
<li>The <b>-cafile </b> option specifies the file that contains all of the
Certificate Authority (CA) certificates in the PEM file format. The default is
<b>cert.pem</b>, in the OpenSSL directory. On Linux/Unix systems, this is
usually "/etc/ssl/ca-bundle.pem". The default file can be overridden via the
<b>SSL_CERT_FILE</b> environment variable.</li>
<li>The <b>-castore</b> option contains the URI to the Certificate Authority
(CA) store, which may be a single container or a catalog of containers.
Starting with OpenSSL 3.2 on Windows, set this to "org.openssl.winstore://" to
use the built-in Windows Certificate Store. The Windows cert store only
supports root certificate stores.</li>
<li>The <b>-request</b> option is used to request the server send its
certificate chain as part of the connection negotiation process. This is
needed to do certificate validation. The default is true. In addition, the
client can manually inspect and accept or reject each certificate using the
<b>-validatecommand</b> option.</li>
<li>The <b>-require</b> option is used to require certificate validation be
performed as part of the connection negotiation process. A valid CA directory,
file, or store must be present for this to work.</li>
</ul>

<br>
<h4>When are command line options needed:</h4>
<p>
By default, a client TLS connection does NOT validate the server certificate
chain. This limitation is due to the lack of a common cross platform
database of Certificate Authority (CA) provided certificates to validate
against. Many Linux systems natively support OpenSSL and thus have these
certificates installed as part of the OS, but MacOS and Windows do not. In
order to use the <b>-require</b> option, one of the following must be true:</p>
<ul>
<li>On Linux and Unix systems with OpenSSL already installed, if the CA
certificates are stored in the standard locations, or the <b>SSL_CERT_DIR</b>
or <b>SSL_CERT_FILE</b> env vars are set, then no other options are needed.</li>

<li>If OpenSSL is not installed in the default location, or when using Mac OS
or Windows and OpenSSL is installed, the <b>SSL_CERT_DIR</b> and/or 
<b>SSL_CERT_FILE</b> env vars or the <b>-cadir</b> and/or <b>-cafile</b>
 options must be defined.</li>

<li>On Windows, starting in OpenSSL 3.2, it is now possible to access the
built-in Windows Certificate Store from OpenSSL. This can be achieved by
setting the <b>-castore</b> option to "<b>org.openssl.winstore://</b>".</li>

<li>If OpenSSL is not installed, the CA certificates must be downloaded and
installed with the user software. The CURL team makes them available at
<a href="https://curl.se/docs/caextract.html">CA certificates extracted
from Mozilla</a> in the <b>cacert.pem</b> file. You must then either
set the <b>SSL_CERT_DIR</b> and/or <b>SSL_CERT_FILE</b> env vars or the
<b>-cadir</b> or <b>-cafile</b> options to the CA cert file's install
location. It is your responsibility to keep this file up to date.</li>
</ul>

<h3><a name="CALLBACK OPTIONS">CALLBACK OPTIONS</a></h3>

<p>
As indicated above, individual channels can be given their own callbacks
to handle intermediate processing by the OpenSSL library, using the
<strong>-command</strong>, <strong>-password</strong>, and
<strong>-validate_command</strong> options passed to either of
<strong>tls::socket</strong> or <strong>tls::import</strong>.
If the callback generates an error, the <b>bgerror</b> command will be
invoked with the error information.
Unlike previous versions of TCL TLS, only if the callback generates an error,
will the <b>bgerror</b> command will be invoked with the error information.

The default behavior when the <strong>-command</strong> and <strong>-validate_command</strong>

<p>The capabilities of this package can vary enormously based upon how the
linked to OpenSSL library was configured and built. New versions may obsolete
older protocol versions, add or remove ciphers, change default values, etc.
Use the <strong>tls::protocols</strong> commands to obtain the supported
protocol versions.</p>

# Running socket tests with a remote server:
# ------------------------------------------
# 
#
# Some tests in socket.test depend on the existence of a remote server to
# which they connect. The remote server must be an instance of tcltest and it
# must run the script found in the file "remote.tcl" in this directory. You
# can start the remote server on any machine reachable from the machine on
# which you want to run the socket tests, by issuing:
# 
#
#     tcltest remote.tcl -port 8048	# Or choose another port number.
# 
#
# If the machine you are running the remote server on has several IP
# interfaces, you can choose which interface the server listens on for
# connections by specifying the -address command line flag, so:
# 
#
#     tcltest remote.tcl -address your.machine.com
# 
#
# These options can also be set by environment variables. On Unix, you can
# type these commands to the shell from which the remote server is started:
# 
#
#     shell% setenv serverPort 8048
#     shell% setenv serverAddress your.machine.com
# 
#
# and subsequently you can start the remote server with:
# 
#
#     tcltest remote.tcl
# 
#
# to have it listen on port 8048 on the interface your.machine.com.
#     
#
# When the server starts, it prints out a detailed message containing its
# configuration information, and it will block until killed with a Ctrl-C.
# Once the remote server exists, you can run the tests in socket.test with
# the server by setting two Tcl variables:
# 
#
#     % set remoteServerIP <name or address of machine on which server runs>
#     % set remoteServerPort 8048
# 
#
# These variables are also settable from the environment. On Unix, you can:
# 
#
#     shell% setenv remoteServerIP machine.where.server.runs
#     shell% setenv remoteServerPort 8048
# 
#
# The preamble of the socket.test file checks to see if the variables are set
# either in Tcl or in the environment; if they are, it attempts to connect to
# the server. If the connection is successful, the tests using the remote
# server will be performed; otherwise, it will attempt to start the remote
# server (via exec) on platforms that support this, on the local host,
# listening at port 8048. If all fails, a message is printed and the tests
# using the remote server are not performed.
