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
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/
- 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
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 --enable-deterministic --with-builtin-dh-params-size=2048
	$ 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-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
  --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


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 the win/README.txt file for the installation instructions.

TLS (aka SSL) Channel - can be layered on any bi-directional Tcl_Channel.

Both client and server-side sockets are possible, and this code should work
on any platform as it uses a generic mechanism for layering on SSL and Tcl.

Acknowledgments
Full filevent sematics should also be intact - see tests directory for
blocking and non-blocking examples.

===============
The current release is TLS 1.6, with binaries built against OpenSSL 0.9.8g.
For best security and function, always compile from source with the latest
official release of OpenSSL (http://www.openssl.org/).

TLS 1.7 and newer require Tcl 8.4.0+, older versions may be used if older
versions of Tcl need to be used.

TclTLS requires OpenSSL or LibreSSL in order to be compiled and function.

	Windows DLL Build instructions using nmake build system
	2020-10-15 [email protected]
	2023-04-23 Brian O'Hagan

Properties:
- 32 bit DLL
- 64 bit DLL
- VisualStudio 2015
Note: Vuisual C++ 6 does not build OpenSSL (long long syntax error)
Note: Visual C++ 6 does not build OpenSSL (long long syntax error)
- Cygwin32 (temporary helper, please help to replace by tclsh)
- OpenSSL statically linked to TCLTLS DLL.
Note: Dynamic linking also works but results in a DLL dependeny on OPENSSL DLL's
Note: Dynamic linking also works but results in a DLL dependency on OPENSSL DLL's

-----------------------------

1) Build OpenSSL static libraries:

set SSLBUILD=\path\to\build\dir
set SSLINSTALL=\path\to\install\dir
set SSLCOMMON=\path\to\common\dir

(1a) Get OpenSSL

  https://github.com/openssl/openssl/releases/download/OpenSSL_1_1_1t/openssl-1.1.1t.tar.gz

OpenSSL source distribtution unpacked in:
c:\test\tcltls\Openssl_1_1_1h
  Unpack OpenSSL source distribution to %SSLBUILD%

(1b) Install Perl from https://strawberryperl.com/

- Install Perl from http://strawberryperl.com/download/5.32.0.1/strawberry-perl-5.32.0.1-32bit.msi
  to C:\perl
  (ActivePerl failed due to missing 32 bit console module)
- Install NASM Assembler:
  https://strawberryperl.com/download/5.32.1.1/strawberry-perl-5.32.1.1-64bit.msi
  Install to C:\Strawberry\perl

(1c) Install NASM Assembler from https://www.nasm.us/

https://www.nasm.us/pub/nasm/releasebuilds/2.15.05/win32/nasm-2.15.05-installer-x86.exe
  to C:\Program Files (x86)\NASM
  
  https://www.nasm.us/pub/nasm/releasebuilds/2.16.01/win64/nasm-2.16.01-installer-x64.exe
  Install to: C:\Program Files\NASM

-> Visual Studio x86 native prompt.
(1d) Configure

set Path=%PATH%;C:\Program Files (x86)\NASM;C:\Perl\perl\bin
  At Visual Studio x86 native prompt:

  set Path=%PATH%;C:\Program Files\NASM;C:\Strawberry\perl\bin
  perl ..\Configure VC-WIN64A no-shared no-filenames threads no-ssl2 no-ssl3 --api=1.1.0 --prefix="%SSLINSTALL%" --openssldir="%SSLCOMMON%" -DOPENSSL_NO_DEPRECATED
  # Not used options: no-asm no-zlib no-comp no-ui-console no-autoload-config
perl Configure VC-WIN32 --prefix=c:\test\tcltls\openssl --openssldir=c:\test\tcltls\openssldir no-shared no-filenames threads

(1e) Build OpenSSL

nmake
nmake test
namke install
  nmake
  nmake test
  nmake install

-----------------------------

2) Build TCLTLS
2) Build TclTLS

set BUILDDIR=\path\to\build\dir
set TCLINSTALL=\path\to\tcl\dir

Unzip distribution in:
2a) Unzip distribution to %BUILDDIR%
c:\test\tcltls\tcltls-1.7.22

-> start cygwin bash prompt
2b) Start BASH shell (MinGW62 Git shell)

cd /cygdrive/c/test/tcltls/tcltls-1.7.22
cd %BUILDDIR%
./gen_dh_params > dh_params.h

od -A n -v -t xC < 'tls.tcl' > tls.tcl.h.new.1
sed 's@[^0-9A-Fa-f]@@g;s@..@0x&, @g' < tls.tcl.h.new.1 > tls.tcl.h
od -A n -v -t xC < 'library/tls.tcl' > tls.tcl.h.new.1
sed 's@[^0-9A-Fa-f]@@g;s@..@0x&, @g' < tls.tcl.h.new.1 > generic/tls.tcl.h
rm -f tls.tcl.h.new.1

-> Visual Studio x86 native prompt.
2c) Start Visual Studio shell

cd C:\test\tcltls\tcltls-1.7.22\win
cd %BUILDDIR%\win

nmake -f makefile.vc TCLDIR=c:\test\tcl8610 SSL_INSTALL_FOLDER=C:\test\tcltls\openssl
nmake -f makefile.vc TCLDIR=%TCLINSTALL% SSL_INSTALL_FOLDER=%SSLINSTALL%
nmake -f makefile.vc install TCLDIR=c:\test\tcl8610 INSTALLDIR=%TCLINSTALL% SSL_INSTALL_FOLDER=%SSLINSTALL%

nmake -f makefile.vc install TCLDIR=c:\test\tcl8610 INSTALLDIR=c:\test\tcltls SSL_INSTALL_FOLDER=C:\test\tcltls\openssl
-----------------------------

3) Test

Start tclsh or wish

lappend auto_path {C:\test\tcltls\tls1.7.22}
package require tls

A small "1.7.22" showing up is hopefully the end of this long way...
package require http
http::register https 443 [list ::tls::socket -autoservername true]
set tok [http::data [http::geturl https://www.tcl-lang.org]]
::http::cleanup $tok
