	*
	* Released and tagged Tcllib 1.12 ========================
	* 

2009-10-27  Andreas Kupries  <andreask@activestate.com>

	* sha256.h: Made the uint*_t typedef's conditional to prevent
	  their use on hpux-ia64. There they are in conflict with the
	  definitions in the system header _inttypes.h.

2009-05-07  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* sha1c.tcl:   Fixed object leak in the critcl implementation.

	* 

2007-05-03  Andreas Kupries  <andreask@activestate.com>

	* sha1.tcl: Force-define loop variable for accel loader, so
	* sha256.tcl: that sak will not fail in the unset when looking
	  for the package version via restricted eval.

2007-03-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* sha256.c: gcc 4 has decided that assignment to a cast pointer is
	to be denied. Therefore added work around.

2007-03-23  Andreas Kupries <andreask@activestate.com>

	* sha256.tcl: Added MD hints.

2007-03-21  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* sha256.c: New files implementing sha256 in C
	* sha256.h: Based on critcl.
	* sha256c.tcl:

	* sha256.tcl:  Rewritten to deal with multiple implementations,
	* sha256.test: i.e. tcl and the new critcl one.

2006-10-11  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* sha1.tcl:  Management of multiple implementations rewritten to
	* sha1.test: conform to the expections of the testsuite helper
	  commands. Testsuite rewritten to use the new helpers.

	*
	* Released and tagged Tcllib 1.9 ========================
	* 

2006-03-12  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* sha1v1.test: Copies of sha1.{tcl,test} for the v1 line.
	* sha1v1.tcl:  This duplication allows us to get rid of the package
	  index hackery for v1, enables the clean conversion of the code
	  in this directory into Tcl Modules, and allows proper separate
	  development of the two major versions in the future.

2006-01-28  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	upon the current interpreter version to try and maximise the speed.

2005-09-30  Andreas Kupries <andreask@activestate.com>

	* sha1.tcl: Applied [SF Tcllib Patch 1301707] to keep the size of
	  generated numbers within the bounds of 32 bits.

2005-02-24  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* sha256.tcl: Speeded up the digest calculation.
	* sha1.tcl:   Arranged to run all available implementations in the
	* sha1.test:  tests. Speeded up the calculation.

2005-02-22  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* sha256.tcl:  Inlined a load of expr calls to speed it up.
	
	* sha256.tcl:  SHA-224 and SHA-256 pure-Tcl implementation
	* sha256.test: Tests from FIPS 180-2 for SHA-224 and SHA-256
	This is the first version. It is correct (in that it passes the
	FIPS test vectors) but slow. Speedups to follow.

2005-02-21  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* sha1.h: replaced the possibly buggy sample extension implementation
	* sha1.c: with shiny new code from the NetBSD project.

	* sha1.test: Added some file tests (16K and 81K)
	* sha1.tcl: Replaced steps 1 and 3 with slightly more efficient
	but equivalent bit operations. Fixed an error with integer length
	exposed with tcl8.5. Verified 8.2-8.5

2005-02-20  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* sha1c.tcl: Imported the sha1 implementation from the Tcl sample
	* sample.h:  extension and created a critcl wrapper.
	* sample.c:  Added to the sak.tcl critcl generation code.
	
	* sha1.tcl:  Re-implemented to support hashing data in chunks
	* sha1.test: Included tests from RFC 2202 for HMAC-SHA1.
	* sha1.man:  This time we have kept the same API but with optional
	extensions to use files/channels and to request the result as
	binary. Now supports token based hashing as in md4, md5 and ripemd.
	Incremented version to 2.0.0

2003-02-06  David N. Welton  <davidw@dedasys.com>

	* sha1.tcl (sha1::time): Use 'lindex' instead of regexp to fetch
	  number from 'time' results.

	* sha1.tcl (initK,sha1): Force 32-bit interpretation of constants

	* sha1.tcl: Fixed dubious code reported by frink.

2001-06-21  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* New module, 'sha1'. The code is Don Libes's <libes@nist.gov>
	  sha1pure, with Donal K. Fellows's patches to speed it up, and
	  extended with a soft dependency on Trf to allow higher speed if
	  the environment is right.
