5 Minor tweaks sync up with bleadperl:
6 - VMS optimizer tweaks to the Makefile.PL
10 Added example to the MD5 POD that shows how to calculate the
11 digest of Unicode strings.
15 2002-05-05 Gisle Aas <gisle@ActiveState.com>
19 More synchronization with tweaks Jarkko have done to the
20 bleadperl test suite. This time various EBCDIC hacks.
22 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
23 the module (and would fail if no previous Digest::MD5 was installed).
24 Patch by Mike Stok <mike@stok.co.uk>
28 2002-05-01 Gisle Aas <gisle@ActiveState.com>
32 One more test suite update from Jarkko to sync it
33 even better with bleadperl.
37 2002-05-01 Gisle Aas <gisle@ActiveState.com>
41 Changes #12954 and #16173 from bleadperl. Documentation typo fix
42 and some signed/unsigned mismatches that Microsoft's C compiler
45 The EBCDIC-aware md5-aaa.t from bleadperl.
49 2002-04-25 Gisle Aas <gisle@ActiveState.com>
53 The SvPVbyte in perl-5.6.1 is buggy. Use the one from 5.7.3
56 Give warning if the function interface is used as instance
57 methods: $md5->md5_hex().
61 2001-09-07 Gisle Aas <gisle@ActiveState.com>
65 Sync up with the bleadperl version:
66 - use SvPVbyte() if avaiable
67 - fixes to make the code 'gcc -Wall'-clean
71 2001-08-27 Gisle Aas <gisle@ActiveState.com>
75 Avoid exit() in Makefile.PL and bleedperls redefinition of printf
76 in the alignment test program.
77 Patch by Doug MacEachern <dougm@covalent.net>.
81 2001-07-18 Gisle Aas <gisle@ActiveState.com>
85 Try to warn if the functional interface is used as methods,
86 i.e. Digest::MD5->md5_hex("foo") will make noise if -w is
89 Document the missing padding for the base64 digests.
91 If both XS bootstrap and locating Digest::Perl::MD5 fails
92 reraise the original XS bootstrap exception.
96 2001-03-13 Gisle Aas <gisle@ActiveState.com>
100 Moved all other Digest:: modules out of the Digest-MD5 dist.
104 2000-09-18 Gisle Aas <gisle@ActiveState.com>
108 Avoid pointer cast warning for machines with bigger ints
109 than pointers. Patch by Robin Barker <rmb1@cise.npl.co.uk>.
113 2000-08-19 Gisle Aas <gisle@ActiveState.com>
117 The fallback code introduced in 2.10 did only work for
118 perl-5.6.0. It should now for for perl5.004 and 5.005
119 as well. Patch by Ville Skyttä <ville@office.popsystems.com>.
123 2000-08-18 Gisle Aas <gisle@ActiveState.com>
127 Digest::MD5 will now try to fallback to the pure perl
128 implementation of Digest::Perl::MD5 if bootstrap fails.
130 Added a bit internal paranoia about casting the IV
131 in the Digest::MD5 object to the MD5_CTX* pointer.
135 1999-08-06 Gisle Aas <gisle@aas.no>
139 Documentation update.
143 1999-07-28 Gisle Aas <gisle@aas.no>
147 The addfile() methods could trigger a core dump when passed
148 a filehandle that had failed to open.
152 1999-04-26 Gisle Aas <gisle@aas.no>
156 The Digest::SHA1 module failed on some 64-bit systems, because I
157 assumed there was a correspondence between the U32 size and
158 BYTEORDER. This version use 'unsigned long' as Uwe's original
161 The module should now work better when liked statically with perl,
162 because we now use a safer module-loaded test in Digest.pm.
164 Assume we know the outcome of the alignment test on VMS. Patch by
165 Chuck Lane <lane@duphy4.physics.drexel.edu>
169 1999-03-26 Gisle Aas <gisle@aas.no>
173 Avoid LONG and BYTE types in SHA.xs as they was in conflict
174 with similar definitions in <winnt.h>.
176 Patch by Marko Asplund <aspa@hip.fi> to make the the alignment
177 test program link successfully with sfio-perl.
179 Fixed a typo in MD5.xs that might have affected 64-bit systems.
180 Spotted by Nick Ing-Simmons
184 1999-03-15 Gisle Aas <gisle@aas.no>
188 Included Digest::SHA1 based on Uwe Hollerbach's SHA module.
192 1999-03-05 Gisle Aas <gisle@aas.no>
196 Avoid the -o option when compiling alignment test program
197 for Win32 as suggested by Gurusamy Sarathy.
199 DEC Compiler bug workaround. Contributed by D Roland Walker
200 <walker@ncbi.nlm.nih.gov>
202 Having references to a local variable called "na" was not
203 very safe either. Some older versions of Perl can apparently
204 macroize this into something completely different.
208 1999-02-27 Gisle Aas <gisle@aas.no>
212 Patch from Christopher J. Madsen <chris_madsen@geocities.com> that
213 should help getting the u32align test program to compile with
214 Visual C++ 5 on Windows NT.
216 Got rid of references to PL_na.
220 1999-01-31 Gisle Aas <gisle@aas.no>
224 Added a hints file as workaround for an IRIX compiler bug.
225 Contributed by D Roland Walker <walker@ncbi.nlm.nih.gov>.
227 Note that the rfc2202 test can still fail on some DEC Alpha,
228 because of a compiler bug that affects the perl 'x' operator.
229 The Digest:: modules should work and be safe to install anyway.
233 1998-12-18 Gisle Aas <aas@sn.no>
237 Some casts and tweaks to make picky compilers more happy.
241 1998-11-04 Gisle Aas <aas@sn.no>
245 Taken out Digest::SHA1 as this module will be provided from Uwe
248 Some tweaks to MD2.xs and MD5.xs since "na" disappeared in
253 1998-10-30 Gisle Aas <aas@sn.no>
257 The 1.99_59 release introduced compilation problems for big-endian
258 systems with free U32 alignment. Bug reported, and fix suggested
259 by Paul J. Schinder <schinder@pobox.com>.
263 1998-10-28 Gisle Aas <aas@sn.no>
267 Makefile.PL will run a test program to find out if U32 values can
268 be aligned anywhere. This hopefully cures the core dumps reported
269 on Solaris and other big endian systems. Thanks to Graham Barr for
274 1998-10-28 Gisle Aas <aas@sn.no>
278 Should be very close to a 2.00 release now. Need some success
279 reports from people running on big-endian machines first I think.
281 Added a Digest::MD2 implementation.
283 Wrote Digest.pm documentation. This define the interface that all
284 Digest:: modules should provide.
286 Avoided some code duplication in MD5.xs
288 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
292 1998-10-27 Gisle Aas <aas@sn.no>
296 Rewritten most of the MD5 C code to make it real fast (especially
297 on little-endian machines without alignment restrictions for U32).
298 Compared to MD5-1.7 we can process files 4 times as fast and we
299 digest small stuff in memory 7 times faster. I came to these
300 conclusions after these tests (gcc -O2, i586, Linux):
302 First tested calculation of the digest of a 31 MB file, using
303 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
307 Digest::MD5-1.99_57: 5.23s
308 md5sum (GNU textutils): 4.90s
310 As you can see, we do nearly as good as the md5sum program. I
311 think the reason we don't beat md5sum is that perl always insist on
312 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
313 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
314 hasher code in a C program I managed to process the file in 4.68s.
316 Then we calculated the digest of the same 6 byte sting, 20000
320 Digest::MD5-1.99_57: 1.68s
322 Digest::MD5 benefit from making this into a plain procedure call
323 instead of a static method call.
326 Other changes in this release are:
330 Internal MD5.xs cleanup.
332 $md5->digest will automatically reset now.
334 Digest::HMAC methods add() and addfile() did not return the
337 Added Digest.pm loading module. I am not sure this is a good idea.
339 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
340 module is just a wrapper around SHA.pm. I hope to get the author
341 of SHA.pm to move his module to the Digest:: category.
345 1998-10-25 Gisle Aas <aas@sn.no>
349 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
350 htovl() as it might evaluate its arguments more than once.
354 1998-10-25 Gisle Aas <aas@sn.no>
358 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
359 Digest::HMAC_MD5. Also provide functional interface. Documentation
362 Included RFC 2202 based test for HMAC-MD5.
366 1998-10-24 Gisle Aas <aas@sn.no>
370 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
372 I have a hard time to make up my mind :-) md5_bin() renamed back
373 to md5(). Functions are not exported by default any more.
375 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
380 1998-10-23 Gisle Aas <aas@sn.no>
384 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
387 The md5() function renamed as md5_bin().
389 The constructor, Digest::MD5->new, no longer takes any extra
392 Added some new tests.
394 Updated the documentation.
396 $md5->b64digest implemented with same base64 encoder as md5_base64.
400 1998-10-23 Gisle Aas <aas@sn.no>
404 Patch from Graham Barr which make it work for big-endian machines
409 1998-10-22 Gisle Aas <aas@sn.no>
413 The MD5 class is now subclassable.
415 The add() and addfile() methods now return $self.
417 The reset() method is just an alias for new().
419 The constructor (MD5->new) now takes optional arguments which are
420 automatically added. It means that we can now write:
422 MD5->new($data)->hexdigest;
424 New $md5->b64digest method.
426 New functions that are exported on request: md5, md5_hex, md5_base64
430 Barely started to update the documentation.
434 1998-10-22 Gisle Aas <aas@sn.no>
438 Much better performance (more than twice as fast now). Mostly
439 because we use Copy/Zero instead of the original MD5_memcpy and
440 MD5_memset functions.
442 The addfile() and hexdigest() methods are now XS implemented.
444 All RSA functions now included in MD5.xs and made static.
446 Use perl's Copy/Zero.
448 Random cleanup, simplifications and reformatting.
449 Merged things better with the perl configuration.
453 Neil Winton's versions below:
456 *** 96/06/20 Version 1.7
458 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
459 32-bit quantities and requires a typedef UINT4 to be defined in
460 global.h. Perl configuration data (the value of BYTEORDER) is used to
461 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
462 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
463 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
464 Makefile.PL will override this.
466 On some machines (at least Cray that I know of) there is no 32-bit
467 integer type. In this case defining TRUNCATE_UINT4 (which is done
468 automatically for a Cray) will ensure that 64-bit values are masked
469 down to 32 bits. I have done my best to test this but without easy
470 access to a true 64-bit machine I can not totally guarantee it (unless
471 anyone wants to lend me a spare Cray :-)
473 There is one remaining limitation for 64-bit enabled processors. The
474 amount of data passed to any single call to the underlying MD5
475 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
476 sorry if that's a real problem for you ...
478 And finally, a minor complilation warning (unsigned char * used with
479 function having char * prototype) has also been eliminated.
481 *** 96/04/09 Version 1.6
483 Re-generated module framework using h2xs to pick up the latest module
484 conventions for versions etc. You can now say "use MD5 1.6;" and things
485 should work correctly. MD5.pod has been integrated into MD5.pm and
486 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
487 which can be invoked via "make test". There are no functional changes
488 to the MD5 routines themselves.
490 *** 96/03/14 Version 1.5.3
492 Fixed addfile method to accept type-glob references for the file-handle
493 (eg \*STDOUT). This is more consistent with other routines and is now the
494 recommended way of passing file-handles. The documentation now gives more
495 examples as to how the routines might be used.
497 *** 96/03/12 Version 1.5.2
499 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
500 support for building on OS/2 (and to work arround a perl -w bug).
502 Remove warning about possible difference between add('foo', 'bar') and
503 add('foobar'). This is not true (it may have been true in the earliest
504 version of the module but is no longer the case).
506 *** 96/03/08 Version 1.5.1
508 Add CHANGES file to make it easier for people to figure out what has
509 been going on. (Meant to do this as part of 1.5)
511 *** 96/03/05 Version 1.5
513 Add hash() and hexhash() methods at the suggestion/request of Gary
514 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
515 of cryptography modules.
517 *** 96/02/27 Version 1.4
519 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
520 Pizzini <kenp@spry.com>!
522 *** 95/11/29 Version 1.3.1
524 Add explanations of current known problems.
526 *** 95/06/02 Version 1.3
528 Fix problems with scope resolution in addfile() reported by
529 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
530 always implicitly in package main while other filehandles aren't.
532 *** 95/05/23 Version 1.2.1
534 [Changes pre 1.2.1 not recorded]
