	* tclconfig/tcl.m4: updated to TEA 3.8

	* tls.c:           Silence 64 bit integer conversion warnings
	* win/nmakehlp.c:  Update build system to support AMD64 target
	* win/makefile.vc: with MSVC8
	* win/rules.vc:

2007-06-22  Jeff Hobbs  <jeffh@ActiveState.com>

	* tlsIO.c (TlsInputProc, TlsOutputProc, TlsWatchProc): 
	* tls.c (VerifyCallback): add an state flag in the verify callback
	that prevents possibly recursion (on 'update'). [Bug 1652380]

	* tests/ciphers.test: reworked to make test output cleaner to
	understand missing ciphers (if any)

	* Makefile.in, tclconfig/tcl.m4: update to TEA 3.6
	* configure, configure.in:       using autoconf-2.59

2007-02-28  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/makefile.vc: Rebase the DLL sensibly. Additional libs for 
	static link of openssl.
	* tls.tcl: bug #1579837 - TIP 278 bug (possibly) - fixed.

2006-03-30  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tclconfig/*:  Updated to TEA 3.5 in response to bug 1460491
	* configure*:   Regenerated configure.

	* Makefile.in:      Removed spurious copying of tls.tcl into the
	                    build directory.

2004-12-22  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* configure.in:     Incremented minor version to 1.5.1
	* configure:        

2004-12-17  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/makefile.vc:  Added the MSVC build system (from the Tcl
	* win/rules.vc:     sampleextension).
	* win/nmakehlp.c:
	* win/tls.rc        Added Windows resource file.
	
	* tls.tcl:          From patch #948155, added support for
	                    alternate socket commands.
	* tls.c:            Quieten some MSVC warnings. Prefer ckalloc
	                    over Tcl_Alloc. (David Graveraux).

2004-06-29  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* pkgIndex.tcl.in, strncasecmp.c (removed):
	* Makefile.in, aclocal.m4, configure, configure.in:
	* tclconfig/README.txt, tclconfig/install-sh, tclconfig/tcl.m4:

2004-03-17  Dan Razzell <research@starfishsystems.ca>

	* tlsX509.c:	Add support for long serial numbers per RFC 3280.
			Format is now hexadecimal. 
			[Request #915313]
			Correctly convert certificate Distinguished Names
			to Tcl string representation.  Eliminates use of
			deprecated OpenSSL function.  Format is now compliant
			with RFC 2253.  [Request #915315]

2004-02-17  Dan Razzell <research@starfishsystems.ca>

2003-07-07  Jeff Hobbs  <jeffh@ActiveState.com>

	* tls.c (Tls_Init):   added tls::misc command provided by
	* tlsX509.c:          Wojciech Kocjan (wojciech kocjan.org)
	* tests/keytest1.tcl: to expose more low-level SSL commands
	* tests/keytest2.tcl:

2003-05-15  Dan Razzell	<research@starfishsystems.ca> 

	* tls.tcl:
	* tlsInt.h:
	* tls.c: add support for binding a password callback to the socket.
	Now each socket can have its own command and password callbacks instead
	of being forced to have all password management pass through a common
	procedure.  The common password procedure is retained for compatibility

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

2000-08-14  Jeff Hobbs  <hobbs@scriptics.com>

	* tlsInt.h:
	* tlsIO.c:

	* tlsIO.c: added support for "corrected" stacked channels.  All
	the above channels are in TCL_CHANNEL_VERSION_2 #ifdefs.

2000-06-05  Scott Stanton  <stanton@ajubasolutions.com>

	* Makefile.in: Fixed broken test target.

	* tlsInt.h: 
	* tls.c: Cleaned up declarations of Tls_Clean to avoid errors on
	Windows (lint).

2000-06-05  Brent Welch <welch@ajubasolutions.com>

	* tls.c, tlsIO.c:  Split Tls_Free into Tls_Clean, which does
	the SSL cleanup, and the Tcl_Free call.  It is important to shutdown

# 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.

	Windows DLL Build instructions using nmake build system
	2020-10-15 Harald.Oehlmann@elmicron.de


Properties:
- 32 bit DLL
- VisualStudio 2015
Note: Vuisual 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

1) Build OpenSSL static libraries:

OpenSSL source distribtution unpacked in:
c:\test\tcltls\Openssl_1_1_1h

- 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://www.nasm.us/pub/nasm/releasebuilds/2.15.05/win32/nasm-2.15.05-installer-x86.exe
  to C:\Program Files (x86)\NASM
  
-> Visual Studio x86 native prompt.

set Path=%PATH%;C:\Program Files (x86)\NASM;C:\Perl\perl\bin

perl Configure VC-WIN32 --prefix=c:\test\tcltls\openssl --openssldir=c:\test\tcltls\openssldir no-shared no-filenames threads

nmake
nmake test
namke install

2) Build TCLTLS

Unzip distribution in:
c:\test\tcltls\tcltls-1.7.22

-> start cygwin bash prompt

cd /cygdrive/c/test/tcltls/tcltls-1.7.22
./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
rm -f tls.tcl.h.new.1

-> Visual Studio x86 native prompt.


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


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


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...

# call nmake with additional parameter SSL_INSTALL_FOLDER= with the
# OpenSSL instalation folder following.

DOTVERSION = 1.7.22
