14 Minor tweaks sync up with bleadperl:
15 - VMS optimizer tweaks to the Makefile.PL
17 - Added alignment test
19 Added example to the MD5 POD that shows how to calculate the
20 digest of Unicode strings.
24 2002-05-05 Gisle Aas <gisle@ActiveState.com>
28 More synchronization with tweaks Jarkko have done to the
29 bleadperl test suite. This time various EBCDIC hacks.
31 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
32 the module (and would fail if no previous Digest::MD5 was installed).
33 Patch by Mike Stok <mike@stok.co.uk>
37 2002-05-01 Gisle Aas <gisle@ActiveState.com>
41 One more test suite update from Jarkko to sync it
42 even better with bleadperl.
46 2002-05-01 Gisle Aas <gisle@ActiveState.com>
50 Changes #12954 and #16173 from bleadperl. Documentation typo fix
51 and some signed/unsigned mismatches that Microsoft's C compiler
54 The EBCDIC-aware md5-aaa.t from bleadperl.
58 2002-04-25 Gisle Aas <gisle@ActiveState.com>
62 The SvPVbyte in perl-5.6.1 is buggy. Use the one from 5.7.3
65 Give warning if the function interface is used as instance
66 methods: $md5->md5_hex().
70 2001-09-07 Gisle Aas <gisle@ActiveState.com>
74 Sync up with the bleadperl version:
75 - use SvPVbyte() if avaiable
76 - fixes to make the code 'gcc -Wall'-clean
80 2001-08-27 Gisle Aas <gisle@ActiveState.com>
84 Avoid exit() in Makefile.PL and bleedperls redefinition of printf
85 in the alignment test program.
86 Patch by Doug MacEachern <dougm@covalent.net>.
90 2001-07-18 Gisle Aas <gisle@ActiveState.com>
94 Try to warn if the functional interface is used as methods,
95 i.e. Digest::MD5->md5_hex("foo") will make noise if -w is
98 Document the missing padding for the base64 digests.
100 If both XS bootstrap and locating Digest::Perl::MD5 fails
101 reraise the original XS bootstrap exception.
105 2001-03-13 Gisle Aas <gisle@ActiveState.com>
109 Moved all other Digest:: modules out of the Digest-MD5 dist.
113 2000-09-18 Gisle Aas <gisle@ActiveState.com>
117 Avoid pointer cast warning for machines with bigger ints
118 than pointers. Patch by Robin Barker <rmb1@cise.npl.co.uk>.
122 2000-08-19 Gisle Aas <gisle@ActiveState.com>
126 The fallback code introduced in 2.10 did only work for
127 perl-5.6.0. It should now for for perl5.004 and 5.005
128 as well. Patch by Ville Skyttä <ville@office.popsystems.com>.
132 2000-08-18 Gisle Aas <gisle@ActiveState.com>
136 Digest::MD5 will now try to fallback to the pure perl
137 implementation of Digest::Perl::MD5 if bootstrap fails.
139 Added a bit internal paranoia about casting the IV
140 in the Digest::MD5 object to the MD5_CTX* pointer.
144 1999-08-06 Gisle Aas <gisle@aas.no>
148 Documentation update.
152 1999-07-28 Gisle Aas <gisle@aas.no>
156 The addfile() methods could trigger a core dump when passed
157 a filehandle that had failed to open.
161 1999-04-26 Gisle Aas <gisle@aas.no>
165 The Digest::SHA1 module failed on some 64-bit systems, because I
166 assumed there was a correspondence between the U32 size and
167 BYTEORDER. This version use 'unsigned long' as Uwe's original
170 The module should now work better when liked statically with perl,
171 because we now use a safer module-loaded test in Digest.pm.
173 Assume we know the outcome of the alignment test on VMS. Patch by
174 Chuck Lane <lane@duphy4.physics.drexel.edu>
178 1999-03-26 Gisle Aas <gisle@aas.no>
182 Avoid LONG and BYTE types in SHA.xs as they was in conflict
183 with similar definitions in <winnt.h>.
185 Patch by Marko Asplund <aspa@hip.fi> to make the the alignment
186 test program link successfully with sfio-perl.
188 Fixed a typo in MD5.xs that might have affected 64-bit systems.
189 Spotted by Nick Ing-Simmons
193 1999-03-15 Gisle Aas <gisle@aas.no>
197 Included Digest::SHA1 based on Uwe Hollerbach's SHA module.
201 1999-03-05 Gisle Aas <gisle@aas.no>
205 Avoid the -o option when compiling alignment test program
206 for Win32 as suggested by Gurusamy Sarathy.
208 DEC Compiler bug workaround. Contributed by D Roland Walker
209 <walker@ncbi.nlm.nih.gov>
211 Having references to a local variable called "na" was not
212 very safe either. Some older versions of Perl can apparently
213 macroize this into something completely different.
217 1999-02-27 Gisle Aas <gisle@aas.no>
221 Patch from Christopher J. Madsen <chris_madsen@geocities.com> that
222 should help getting the u32align test program to compile with
223 Visual C++ 5 on Windows NT.
225 Got rid of references to PL_na.
229 1999-01-31 Gisle Aas <gisle@aas.no>
233 Added a hints file as workaround for an IRIX compiler bug.
234 Contributed by D Roland Walker <walker@ncbi.nlm.nih.gov>.
236 Note that the rfc2202 test can still fail on some DEC Alpha,
237 because of a compiler bug that affects the perl 'x' operator.
238 The Digest:: modules should work and be safe to install anyway.
242 1998-12-18 Gisle Aas <aas@sn.no>
246 Some casts and tweaks to make picky compilers more happy.
250 1998-11-04 Gisle Aas <aas@sn.no>
254 Taken out Digest::SHA1 as this module will be provided from Uwe
257 Some tweaks to MD2.xs and MD5.xs since "na" disappeared in
262 1998-10-30 Gisle Aas <aas@sn.no>
266 The 1.99_59 release introduced compilation problems for big-endian
267 systems with free U32 alignment. Bug reported, and fix suggested
268 by Paul J. Schinder <schinder@pobox.com>.
272 1998-10-28 Gisle Aas <aas@sn.no>
276 Makefile.PL will run a test program to find out if U32 values can
277 be aligned anywhere. This hopefully cures the core dumps reported
278 on Solaris and other big endian systems. Thanks to Graham Barr for
283 1998-10-28 Gisle Aas <aas@sn.no>
287 Should be very close to a 2.00 release now. Need some success
288 reports from people running on big-endian machines first I think.
290 Added a Digest::MD2 implementation.
292 Wrote Digest.pm documentation. This define the interface that all
293 Digest:: modules should provide.
295 Avoided some code duplication in MD5.xs
297 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
301 1998-10-27 Gisle Aas <aas@sn.no>
305 Rewritten most of the MD5 C code to make it real fast (especially
306 on little-endian machines without alignment restrictions for U32).
307 Compared to MD5-1.7 we can process files 4 times as fast and we
308 digest small stuff in memory 7 times faster. I came to these
309 conclusions after these tests (gcc -O2, i586, Linux):
311 First tested calculation of the digest of a 31 MB file, using
312 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
316 Digest::MD5-1.99_57: 5.23s
317 md5sum (GNU textutils): 4.90s
319 As you can see, we do nearly as good as the md5sum program. I
320 think the reason we don't beat md5sum is that perl always insist on
321 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
322 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
323 hasher code in a C program I managed to process the file in 4.68s.
325 Then we calculated the digest of the same 6 byte sting, 20000
329 Digest::MD5-1.99_57: 1.68s
331 Digest::MD5 benefit from making this into a plain procedure call
332 instead of a static method call.
335 Other changes in this release are:
339 Internal MD5.xs cleanup.
341 $md5->digest will automatically reset now.
343 Digest::HMAC methods add() and addfile() did not return the
346 Added Digest.pm loading module. I am not sure this is a good idea.
348 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
349 module is just a wrapper around SHA.pm. I hope to get the author
350 of SHA.pm to move his module to the Digest:: category.
354 1998-10-25 Gisle Aas <aas@sn.no>
358 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
359 htovl() as it might evaluate its arguments more than once.
363 1998-10-25 Gisle Aas <aas@sn.no>
367 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
368 Digest::HMAC_MD5. Also provide functional interface. Documentation
371 Included RFC 2202 based test for HMAC-MD5.
375 1998-10-24 Gisle Aas <aas@sn.no>
379 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
381 I have a hard time to make up my mind :-) md5_bin() renamed back
382 to md5(). Functions are not exported by default any more.
384 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
389 1998-10-23 Gisle Aas <aas@sn.no>
393 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
396 The md5() function renamed as md5_bin().
398 The constructor, Digest::MD5->new, no longer takes any extra
401 Added some new tests.
403 Updated the documentation.
405 $md5->b64digest implemented with same base64 encoder as md5_base64.
409 1998-10-23 Gisle Aas <aas@sn.no>
413 Patch from Graham Barr which make it work for big-endian machines
418 1998-10-22 Gisle Aas <aas@sn.no>
422 The MD5 class is now subclassable.
424 The add() and addfile() methods now return $self.
426 The reset() method is just an alias for new().
428 The constructor (MD5->new) now takes optional arguments which are
429 automatically added. It means that we can now write:
431 MD5->new($data)->hexdigest;
433 New $md5->b64digest method.
435 New functions that are exported on request: md5, md5_hex, md5_base64
439 Barely started to update the documentation.
443 1998-10-22 Gisle Aas <aas@sn.no>
447 Much better performance (more than twice as fast now). Mostly
448 because we use Copy/Zero instead of the original MD5_memcpy and
449 MD5_memset functions.
451 The addfile() and hexdigest() methods are now XS implemented.
453 All RSA functions now included in MD5.xs and made static.
455 Use perl's Copy/Zero.
457 Random cleanup, simplifications and reformatting.
458 Merged things better with the perl configuration.
462 Neil Winton's versions below:
465 *** 96/06/20 Version 1.7
467 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
468 32-bit quantities and requires a typedef UINT4 to be defined in
469 global.h. Perl configuration data (the value of BYTEORDER) is used to
470 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
471 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
472 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
473 Makefile.PL will override this.
475 On some machines (at least Cray that I know of) there is no 32-bit
476 integer type. In this case defining TRUNCATE_UINT4 (which is done
477 automatically for a Cray) will ensure that 64-bit values are masked
478 down to 32 bits. I have done my best to test this but without easy
479 access to a true 64-bit machine I can not totally guarantee it (unless
480 anyone wants to lend me a spare Cray :-)
482 There is one remaining limitation for 64-bit enabled processors. The
483 amount of data passed to any single call to the underlying MD5
484 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
485 sorry if that's a real problem for you ...
487 And finally, a minor complilation warning (unsigned char * used with
488 function having char * prototype) has also been eliminated.
490 *** 96/04/09 Version 1.6
492 Re-generated module framework using h2xs to pick up the latest module
493 conventions for versions etc. You can now say "use MD5 1.6;" and things
494 should work correctly. MD5.pod has been integrated into MD5.pm and
495 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
496 which can be invoked via "make test". There are no functional changes
497 to the MD5 routines themselves.
499 *** 96/03/14 Version 1.5.3
501 Fixed addfile method to accept type-glob references for the file-handle
502 (eg \*STDOUT). This is more consistent with other routines and is now the
503 recommended way of passing file-handles. The documentation now gives more
504 examples as to how the routines might be used.
506 *** 96/03/12 Version 1.5.2
508 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
509 support for building on OS/2 (and to work arround a perl -w bug).
511 Remove warning about possible difference between add('foo', 'bar') and
512 add('foobar'). This is not true (it may have been true in the earliest
513 version of the module but is no longer the case).
515 *** 96/03/08 Version 1.5.1
517 Add CHANGES file to make it easier for people to figure out what has
518 been going on. (Meant to do this as part of 1.5)
520 *** 96/03/05 Version 1.5
522 Add hash() and hexhash() methods at the suggestion/request of Gary
523 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
524 of cryptography modules.
526 *** 96/02/27 Version 1.4
528 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
529 Pizzini <kenp@spry.com>!
531 *** 95/11/29 Version 1.3.1
533 Add explanations of current known problems.
535 *** 95/06/02 Version 1.3
537 Fix problems with scope resolution in addfile() reported by
538 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
539 always implicitly in package main while other filehandles aren't.
541 *** 95/05/23 Version 1.2.1
543 [Changes pre 1.2.1 not recorded]
