23 Minor tweaks sync up with bleadperl:
24 - VMS optimizer tweaks to the Makefile.PL
26 - Added alignment test
28 Added example to the MD5 POD that shows how to calculate the
29 digest of Unicode strings.
33 2002-05-05 Gisle Aas <gisle@ActiveState.com>
37 More synchronization with tweaks Jarkko have done to the
38 bleadperl test suite. This time various EBCDIC hacks.
40 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
41 the module (and would fail if no previous Digest::MD5 was installed).
42 Patch by Mike Stok <mike@stok.co.uk>
46 2002-05-01 Gisle Aas <gisle@ActiveState.com>
50 One more test suite update from Jarkko to sync it
51 even better with bleadperl.
55 2002-05-01 Gisle Aas <gisle@ActiveState.com>
59 Changes #12954 and #16173 from bleadperl. Documentation typo fix
60 and some signed/unsigned mismatches that Microsoft's C compiler
63 The EBCDIC-aware md5-aaa.t from bleadperl.
67 2002-04-25 Gisle Aas <gisle@ActiveState.com>
71 The SvPVbyte in perl-5.6.1 is buggy. Use the one from 5.7.3
74 Give warning if the function interface is used as instance
75 methods: $md5->md5_hex().
79 2001-09-07 Gisle Aas <gisle@ActiveState.com>
83 Sync up with the bleadperl version:
84 - use SvPVbyte() if avaiable
85 - fixes to make the code 'gcc -Wall'-clean
89 2001-08-27 Gisle Aas <gisle@ActiveState.com>
93 Avoid exit() in Makefile.PL and bleedperls redefinition of printf
94 in the alignment test program.
95 Patch by Doug MacEachern <dougm@covalent.net>.
99 2001-07-18 Gisle Aas <gisle@ActiveState.com>
103 Try to warn if the functional interface is used as methods,
104 i.e. Digest::MD5->md5_hex("foo") will make noise if -w is
107 Document the missing padding for the base64 digests.
109 If both XS bootstrap and locating Digest::Perl::MD5 fails
110 reraise the original XS bootstrap exception.
114 2001-03-13 Gisle Aas <gisle@ActiveState.com>
118 Moved all other Digest:: modules out of the Digest-MD5 dist.
122 2000-09-18 Gisle Aas <gisle@ActiveState.com>
126 Avoid pointer cast warning for machines with bigger ints
127 than pointers. Patch by Robin Barker <rmb1@cise.npl.co.uk>.
131 2000-08-19 Gisle Aas <gisle@ActiveState.com>
135 The fallback code introduced in 2.10 did only work for
136 perl-5.6.0. It should now for for perl5.004 and 5.005
137 as well. Patch by Ville Skyttä <ville@office.popsystems.com>.
141 2000-08-18 Gisle Aas <gisle@ActiveState.com>
145 Digest::MD5 will now try to fallback to the pure perl
146 implementation of Digest::Perl::MD5 if bootstrap fails.
148 Added a bit internal paranoia about casting the IV
149 in the Digest::MD5 object to the MD5_CTX* pointer.
153 1999-08-06 Gisle Aas <gisle@aas.no>
157 Documentation update.
161 1999-07-28 Gisle Aas <gisle@aas.no>
165 The addfile() methods could trigger a core dump when passed
166 a filehandle that had failed to open.
170 1999-04-26 Gisle Aas <gisle@aas.no>
174 The Digest::SHA1 module failed on some 64-bit systems, because I
175 assumed there was a correspondence between the U32 size and
176 BYTEORDER. This version use 'unsigned long' as Uwe's original
179 The module should now work better when liked statically with perl,
180 because we now use a safer module-loaded test in Digest.pm.
182 Assume we know the outcome of the alignment test on VMS. Patch by
183 Chuck Lane <lane@duphy4.physics.drexel.edu>
187 1999-03-26 Gisle Aas <gisle@aas.no>
191 Avoid LONG and BYTE types in SHA.xs as they was in conflict
192 with similar definitions in <winnt.h>.
194 Patch by Marko Asplund <aspa@hip.fi> to make the the alignment
195 test program link successfully with sfio-perl.
197 Fixed a typo in MD5.xs that might have affected 64-bit systems.
198 Spotted by Nick Ing-Simmons
202 1999-03-15 Gisle Aas <gisle@aas.no>
206 Included Digest::SHA1 based on Uwe Hollerbach's SHA module.
210 1999-03-05 Gisle Aas <gisle@aas.no>
214 Avoid the -o option when compiling alignment test program
215 for Win32 as suggested by Gurusamy Sarathy.
217 DEC Compiler bug workaround. Contributed by D Roland Walker
218 <walker@ncbi.nlm.nih.gov>
220 Having references to a local variable called "na" was not
221 very safe either. Some older versions of Perl can apparently
222 macroize this into something completely different.
226 1999-02-27 Gisle Aas <gisle@aas.no>
230 Patch from Christopher J. Madsen <chris_madsen@geocities.com> that
231 should help getting the u32align test program to compile with
232 Visual C++ 5 on Windows NT.
234 Got rid of references to PL_na.
238 1999-01-31 Gisle Aas <gisle@aas.no>
242 Added a hints file as workaround for an IRIX compiler bug.
243 Contributed by D Roland Walker <walker@ncbi.nlm.nih.gov>.
245 Note that the rfc2202 test can still fail on some DEC Alpha,
246 because of a compiler bug that affects the perl 'x' operator.
247 The Digest:: modules should work and be safe to install anyway.
251 1998-12-18 Gisle Aas <aas@sn.no>
255 Some casts and tweaks to make picky compilers more happy.
259 1998-11-04 Gisle Aas <aas@sn.no>
263 Taken out Digest::SHA1 as this module will be provided from Uwe
266 Some tweaks to MD2.xs and MD5.xs since "na" disappeared in
271 1998-10-30 Gisle Aas <aas@sn.no>
275 The 1.99_59 release introduced compilation problems for big-endian
276 systems with free U32 alignment. Bug reported, and fix suggested
277 by Paul J. Schinder <schinder@pobox.com>.
281 1998-10-28 Gisle Aas <aas@sn.no>
285 Makefile.PL will run a test program to find out if U32 values can
286 be aligned anywhere. This hopefully cures the core dumps reported
287 on Solaris and other big endian systems. Thanks to Graham Barr for
292 1998-10-28 Gisle Aas <aas@sn.no>
296 Should be very close to a 2.00 release now. Need some success
297 reports from people running on big-endian machines first I think.
299 Added a Digest::MD2 implementation.
301 Wrote Digest.pm documentation. This define the interface that all
302 Digest:: modules should provide.
304 Avoided some code duplication in MD5.xs
306 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
310 1998-10-27 Gisle Aas <aas@sn.no>
314 Rewritten most of the MD5 C code to make it real fast (especially
315 on little-endian machines without alignment restrictions for U32).
316 Compared to MD5-1.7 we can process files 4 times as fast and we
317 digest small stuff in memory 7 times faster. I came to these
318 conclusions after these tests (gcc -O2, i586, Linux):
320 First tested calculation of the digest of a 31 MB file, using
321 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
325 Digest::MD5-1.99_57: 5.23s
326 md5sum (GNU textutils): 4.90s
328 As you can see, we do nearly as good as the md5sum program. I
329 think the reason we don't beat md5sum is that perl always insist on
330 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
331 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
332 hasher code in a C program I managed to process the file in 4.68s.
334 Then we calculated the digest of the same 6 byte sting, 20000
338 Digest::MD5-1.99_57: 1.68s
340 Digest::MD5 benefit from making this into a plain procedure call
341 instead of a static method call.
344 Other changes in this release are:
348 Internal MD5.xs cleanup.
350 $md5->digest will automatically reset now.
352 Digest::HMAC methods add() and addfile() did not return the
355 Added Digest.pm loading module. I am not sure this is a good idea.
357 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
358 module is just a wrapper around SHA.pm. I hope to get the author
359 of SHA.pm to move his module to the Digest:: category.
363 1998-10-25 Gisle Aas <aas@sn.no>
367 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
368 htovl() as it might evaluate its arguments more than once.
372 1998-10-25 Gisle Aas <aas@sn.no>
376 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
377 Digest::HMAC_MD5. Also provide functional interface. Documentation
380 Included RFC 2202 based test for HMAC-MD5.
384 1998-10-24 Gisle Aas <aas@sn.no>
388 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
390 I have a hard time to make up my mind :-) md5_bin() renamed back
391 to md5(). Functions are not exported by default any more.
393 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
398 1998-10-23 Gisle Aas <aas@sn.no>
402 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
405 The md5() function renamed as md5_bin().
407 The constructor, Digest::MD5->new, no longer takes any extra
410 Added some new tests.
412 Updated the documentation.
414 $md5->b64digest implemented with same base64 encoder as md5_base64.
418 1998-10-23 Gisle Aas <aas@sn.no>
422 Patch from Graham Barr which make it work for big-endian machines
427 1998-10-22 Gisle Aas <aas@sn.no>
431 The MD5 class is now subclassable.
433 The add() and addfile() methods now return $self.
435 The reset() method is just an alias for new().
437 The constructor (MD5->new) now takes optional arguments which are
438 automatically added. It means that we can now write:
440 MD5->new($data)->hexdigest;
442 New $md5->b64digest method.
444 New functions that are exported on request: md5, md5_hex, md5_base64
448 Barely started to update the documentation.
452 1998-10-22 Gisle Aas <aas@sn.no>
456 Much better performance (more than twice as fast now). Mostly
457 because we use Copy/Zero instead of the original MD5_memcpy and
458 MD5_memset functions.
460 The addfile() and hexdigest() methods are now XS implemented.
462 All RSA functions now included in MD5.xs and made static.
464 Use perl's Copy/Zero.
466 Random cleanup, simplifications and reformatting.
467 Merged things better with the perl configuration.
471 Neil Winton's versions below:
474 *** 96/06/20 Version 1.7
476 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
477 32-bit quantities and requires a typedef UINT4 to be defined in
478 global.h. Perl configuration data (the value of BYTEORDER) is used to
479 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
480 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
481 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
482 Makefile.PL will override this.
484 On some machines (at least Cray that I know of) there is no 32-bit
485 integer type. In this case defining TRUNCATE_UINT4 (which is done
486 automatically for a Cray) will ensure that 64-bit values are masked
487 down to 32 bits. I have done my best to test this but without easy
488 access to a true 64-bit machine I can not totally guarantee it (unless
489 anyone wants to lend me a spare Cray :-)
491 There is one remaining limitation for 64-bit enabled processors. The
492 amount of data passed to any single call to the underlying MD5
493 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
494 sorry if that's a real problem for you ...
496 And finally, a minor complilation warning (unsigned char * used with
497 function having char * prototype) has also been eliminated.
499 *** 96/04/09 Version 1.6
501 Re-generated module framework using h2xs to pick up the latest module
502 conventions for versions etc. You can now say "use MD5 1.6;" and things
503 should work correctly. MD5.pod has been integrated into MD5.pm and
504 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
505 which can be invoked via "make test". There are no functional changes
506 to the MD5 routines themselves.
508 *** 96/03/14 Version 1.5.3
510 Fixed addfile method to accept type-glob references for the file-handle
511 (eg \*STDOUT). This is more consistent with other routines and is now the
512 recommended way of passing file-handles. The documentation now gives more
513 examples as to how the routines might be used.
515 *** 96/03/12 Version 1.5.2
517 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
518 support for building on OS/2 (and to work arround a perl -w bug).
520 Remove warning about possible difference between add('foo', 'bar') and
521 add('foobar'). This is not true (it may have been true in the earliest
522 version of the module but is no longer the case).
524 *** 96/03/08 Version 1.5.1
526 Add CHANGES file to make it easier for people to figure out what has
527 been going on. (Meant to do this as part of 1.5)
529 *** 96/03/05 Version 1.5
531 Add hash() and hexhash() methods at the suggestion/request of Gary
532 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
533 of cryptography modules.
535 *** 96/02/27 Version 1.4
537 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
538 Pizzini <kenp@spry.com>!
540 *** 95/11/29 Version 1.3.1
542 Add explanations of current known problems.
544 *** 95/06/02 Version 1.3
546 Fix problems with scope resolution in addfile() reported by
547 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
548 always implicitly in package main while other filehandles aren't.
550 *** 95/05/23 Version 1.2.1
552 [Changes pre 1.2.1 not recorded]
