5 More synchronization with tweaks Jarkko have done to the
6 bleadperl test suite. This time various EBCDIC hacks.
8 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
9 the module (and would fail if no previous Digest::MD5 was installed).
10 Patch by Mike Stok <mike@stok.co.uk>
14 2002-05-01 Gisle Aas <gisle@ActiveState.com>
18 One more test suite update from Jarkko to sync it
19 even better with bleadperl.
23 2002-05-01 Gisle Aas <gisle@ActiveState.com>
27 Changes #12954 and #16173 from bleadperl. Documentation typo fix
28 and some signed/unsigned mismatches that Microsoft's C compiler
31 The EBCDIC-aware md5-aaa.t from bleadperl.

39 The SvPVbyte in perl-5.6.1 is buggy. Use the one from 5.7.3
42 Give warning if the function interface is used as instance
43 methods: $md5->md5_hex().
47 2001-09-07 Gisle Aas <gisle@ActiveState.com>
51 Sync up with the bleadperl version:
52 - use SvPVbyte() if avaiable
53 - fixes to make the code 'gcc -Wall'-clean
57 2001-08-27 Gisle Aas <gisle@ActiveState.com>
61 Avoid exit() in Makefile.PL and bleedperls redefinition of printf
62 in the alignment test program.
63 Patch by Doug MacEachern <dougm@covalent.net>.
67 2001-07-18 Gisle Aas <gisle@ActiveState.com>
71 Try to warn if the functional interface is used as methods,
72 i.e. Digest::MD5->md5_hex("foo") will make noise if -w is
75 Document the missing padding for the base64 digests.
77 If both XS bootstrap and locating Digest::Perl::MD5 fails
78 reraise the original XS bootstrap exception.
82 2001-03-13 Gisle Aas <gisle@ActiveState.com>
86 Moved all other Digest:: modules out of the Digest-MD5 dist.
90 2000-09-18 Gisle Aas <gisle@ActiveState.com>
94 Avoid pointer cast warning for machines with bigger ints
95 than pointers. Patch by Robin Barker <rmb1@cise.npl.co.uk>.
99 2000-08-19 Gisle Aas <gisle@ActiveState.com>
103 The fallback code introduced in 2.10 did only work for
104 perl-5.6.0. It should now for for perl5.004 and 5.005
105 as well. Patch by Ville Skyttä <ville@office.popsystems.com>.
109 2000-08-18 Gisle Aas <gisle@ActiveState.com>
113 Digest::MD5 will now try to fallback to the pure perl
114 implementation of Digest::Perl::MD5 if bootstrap fails.
116 Added a bit internal paranoia about casting the IV
117 in the Digest::MD5 object to the MD5_CTX* pointer.
121 1999-08-06 Gisle Aas <gisle@aas.no>
125 Documentation update.
129 1999-07-28 Gisle Aas <gisle@aas.no>
133 The addfile() methods could trigger a core dump when passed
134 a filehandle that had failed to open.
138 1999-04-26 Gisle Aas <gisle@aas.no>
142 The Digest::SHA1 module failed on some 64-bit systems, because I
143 assumed there was a correspondence between the U32 size and
144 BYTEORDER. This version use 'unsigned long' as Uwe's original
147 The module should now work better when liked statically with perl,
148 because we now use a safer module-loaded test in Digest.pm.
150 Assume we know the outcome of the alignment test on VMS. Patch by
151 Chuck Lane <lane@duphy4.physics.drexel.edu>
155 1999-03-26 Gisle Aas <gisle@aas.no>
159 Avoid LONG and BYTE types in SHA.xs as they was in conflict
160 with similar definitions in <winnt.h>.
162 Patch by Marko Asplund <aspa@hip.fi> to make the the alignment
163 test program link successfully with sfio-perl.
165 Fixed a typo in MD5.xs that might have affected 64-bit systems.
166 Spotted by Nick Ing-Simmons
170 1999-03-15 Gisle Aas <gisle@aas.no>
174 Included Digest::SHA1 based on Uwe Hollerbach's SHA module.
178 1999-03-05 Gisle Aas <gisle@aas.no>
182 Avoid the -o option when compiling alignment test program
183 for Win32 as suggested by Gurusamy Sarathy.
185 DEC Compiler bug workaround. Contributed by D Roland Walker
186 <walker@ncbi.nlm.nih.gov>
188 Having references to a local variable called "na" was not
189 very safe either. Some older versions of Perl can apparently
190 macroize this into something completely different.
194 1999-02-27 Gisle Aas <gisle@aas.no>
198 Patch from Christopher J. Madsen <chris_madsen@geocities.com> that
199 should help getting the u32align test program to compile with
200 Visual C++ 5 on Windows NT.
202 Got rid of references to PL_na.
206 1999-01-31 Gisle Aas <gisle@aas.no>
210 Added a hints file as workaround for an IRIX compiler bug.
211 Contributed by D Roland Walker <walker@ncbi.nlm.nih.gov>.
213 Note that the rfc2202 test can still fail on some DEC Alpha,
214 because of a compiler bug that affects the perl 'x' operator.
215 The Digest:: modules should work and be safe to install anyway.
219 1998-12-18 Gisle Aas <aas@sn.no>
223 Some casts and tweaks to make picky compilers more happy.
227 1998-11-04 Gisle Aas <aas@sn.no>
231 Taken out Digest::SHA1 as this module will be provided from Uwe
234 Some tweaks to MD2.xs and MD5.xs since "na" disappeared in
239 1998-10-30 Gisle Aas <aas@sn.no>
243 The 1.99_59 release introduced compilation problems for big-endian
244 systems with free U32 alignment. Bug reported, and fix suggested
245 by Paul J. Schinder <schinder@pobox.com>.
249 1998-10-28 Gisle Aas <aas@sn.no>
253 Makefile.PL will run a test program to find out if U32 values can
254 be aligned anywhere. This hopefully cures the core dumps reported
255 on Solaris and other big endian systems. Thanks to Graham Barr for
260 1998-10-28 Gisle Aas <aas@sn.no>
264 Should be very close to a 2.00 release now. Need some success
265 reports from people running on big-endian machines first I think.
267 Added a Digest::MD2 implementation.
269 Wrote Digest.pm documentation. This define the interface that all
270 Digest:: modules should provide.
272 Avoided some code duplication in MD5.xs
274 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
278 1998-10-27 Gisle Aas <aas@sn.no>
282 Rewritten most of the MD5 C code to make it real fast (especially
283 on little-endian machines without alignment restrictions for U32).
284 Compared to MD5-1.7 we can process files 4 times as fast and we
285 digest small stuff in memory 7 times faster. I came to these
286 conclusions after these tests (gcc -O2, i586, Linux):
288 First tested calculation of the digest of a 31 MB file, using
289 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
293 Digest::MD5-1.99_57: 5.23s
294 md5sum (GNU textutils): 4.90s
296 As you can see, we do nearly as good as the md5sum program. I
297 think the reason we don't beat md5sum is that perl always insist on
298 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
299 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
300 hasher code in a C program I managed to process the file in 4.68s.
302 Then we calculated the digest of the same 6 byte sting, 20000
306 Digest::MD5-1.99_57: 1.68s
308 Digest::MD5 benefit from making this into a plain procedure call
309 instead of a static method call.
312 Other changes in this release are:
316 Internal MD5.xs cleanup.
318 $md5->digest will automatically reset now.
320 Digest::HMAC methods add() and addfile() did not return the
323 Added Digest.pm loading module. I am not sure this is a good idea.
325 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
326 module is just a wrapper around SHA.pm. I hope to get the author
327 of SHA.pm to move his module to the Digest:: category.
331 1998-10-25 Gisle Aas <aas@sn.no>
335 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
336 htovl() as it might evaluate its arguments more than once.
340 1998-10-25 Gisle Aas <aas@sn.no>
344 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
345 Digest::HMAC_MD5. Also provide functional interface. Documentation
348 Included RFC 2202 based test for HMAC-MD5.
352 1998-10-24 Gisle Aas <aas@sn.no>
356 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
358 I have a hard time to make up my mind :-) md5_bin() renamed back
359 to md5(). Functions are not exported by default any more.
361 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
366 1998-10-23 Gisle Aas <aas@sn.no>
370 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
373 The md5() function renamed as md5_bin().
375 The constructor, Digest::MD5->new, no longer takes any extra
378 Added some new tests.
380 Updated the documentation.
382 $md5->b64digest implemented with same base64 encoder as md5_base64.
386 1998-10-23 Gisle Aas <aas@sn.no>
390 Patch from Graham Barr which make it work for big-endian machines
395 1998-10-22 Gisle Aas <aas@sn.no>
399 The MD5 class is now subclassable.
401 The add() and addfile() methods now return $self.
403 The reset() method is just an alias for new().
405 The constructor (MD5->new) now takes optional arguments which are
406 automatically added. It means that we can now write:
408 MD5->new($data)->hexdigest;
410 New $md5->b64digest method.
412 New functions that are exported on request: md5, md5_hex, md5_base64
416 Barely started to update the documentation.
420 1998-10-22 Gisle Aas <aas@sn.no>
424 Much better performance (more than twice as fast now). Mostly
425 because we use Copy/Zero instead of the original MD5_memcpy and
426 MD5_memset functions.
428 The addfile() and hexdigest() methods are now XS implemented.
430 All RSA functions now included in MD5.xs and made static.
432 Use perl's Copy/Zero.
434 Random cleanup, simplifications and reformatting.
435 Merged things better with the perl configuration.
439 Neil Winton's versions below:
442 *** 96/06/20 Version 1.7
444 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
445 32-bit quantities and requires a typedef UINT4 to be defined in
446 global.h. Perl configuration data (the value of BYTEORDER) is used to
447 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
448 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
449 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
450 Makefile.PL will override this.
452 On some machines (at least Cray that I know of) there is no 32-bit
453 integer type. In this case defining TRUNCATE_UINT4 (which is done
454 automatically for a Cray) will ensure that 64-bit values are masked
455 down to 32 bits. I have done my best to test this but without easy
456 access to a true 64-bit machine I can not totally guarantee it (unless
457 anyone wants to lend me a spare Cray :-)
459 There is one remaining limitation for 64-bit enabled processors. The
460 amount of data passed to any single call to the underlying MD5
461 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
462 sorry if that's a real problem for you ...
464 And finally, a minor complilation warning (unsigned char * used with
465 function having char * prototype) has also been eliminated.
467 *** 96/04/09 Version 1.6
469 Re-generated module framework using h2xs to pick up the latest module
470 conventions for versions etc. You can now say "use MD5 1.6;" and things
471 should work correctly. MD5.pod has been integrated into MD5.pm and
472 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
473 which can be invoked via "make test". There are no functional changes
474 to the MD5 routines themselves.
476 *** 96/03/14 Version 1.5.3
478 Fixed addfile method to accept type-glob references for the file-handle
479 (eg \*STDOUT). This is more consistent with other routines and is now the
480 recommended way of passing file-handles. The documentation now gives more
481 examples as to how the routines might be used.
483 *** 96/03/12 Version 1.5.2
485 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
486 support for building on OS/2 (and to work arround a perl -w bug).
488 Remove warning about possible difference between add('foo', 'bar') and
489 add('foobar'). This is not true (it may have been true in the earliest
490 version of the module but is no longer the case).
492 *** 96/03/08 Version 1.5.1
494 Add CHANGES file to make it easier for people to figure out what has
495 been going on. (Meant to do this as part of 1.5)
497 *** 96/03/05 Version 1.5
499 Add hash() and hexhash() methods at the suggestion/request of Gary
500 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
501 of cryptography modules.
503 *** 96/02/27 Version 1.4
505 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
506 Pizzini <kenp@spry.com>!
508 *** 95/11/29 Version 1.3.1
510 Add explanations of current known problems.
512 *** 95/06/02 Version 1.3
514 Fix problems with scope resolution in addfile() reported by
515 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
516 always implicitly in package main while other filehandles aren't.
518 *** 95/05/23 Version 1.2.1
520 [Changes pre 1.2.1 not recorded]
