5 Some tweaks to make the module build on perl-5.004 and
10 2003-10-06 Gisle Aas <gisle@ActiveState.com>
14 Another try. Forgot to update the test checksums.
18 2003-10-06 Gisle Aas <gisle@ActiveState.com>
22 Fix minor documentation typo.
26 2003-08-04 Gisle Aas <gisle@ActiveState.com>
30 Avoid having to figure how to compile alignment test program
31 on MS-Windows by just assume free alignment as for i386. Source
32 builds on Windows was apparently broken.
36 2003-07-21 Gisle Aas <gisle@ActiveState.com>
40 Don't assume PerlIO_read() works like fread() even though
41 it was documented like that for perl 5.6. It returns negative
44 Kill test #3 in t/badfile.t. I don't know a reliable way
45 to test read failures on a file handle. Seems better not to
46 test than to make many worry.
50 2003-07-04 Gisle Aas <gisle@ActiveState.com>
54 The $md5->addfile method now croaks if it discovers
55 errors on the handle after reading from it. This should
56 make it more difficult to end up with the wrong digest
57 just because you are to lazy to check the error status
58 on your file handles after reading from them.
60 Improved documentation.
62 Sync up with bleadperl; even safer patchlevel include.
66 2003-03-09 Gisle Aas <gisle@ActiveState.com>
70 Don't let the $^W test get confused by lexical warnings.
72 Sync up with bleadperl; safer patchlevel include.
76 2003-01-18 Gisle Aas <gisle@ActiveState.com>
80 Override INSTALLDIRS for 5.8 as suggested by
81 Guido Ostkamp <Guido.Ostkamp@t-online.de>.

98 Minor tweaks sync up with bleadperl:
99 - VMS optimizer tweaks to the Makefile.PL
101 - Added alignment test
103 Added example to the MD5 POD that shows how to calculate the
104 digest of Unicode strings.
108 2002-05-05 Gisle Aas <gisle@ActiveState.com>
112 More synchronization with tweaks Jarkko have done to the
113 bleadperl test suite. This time various EBCDIC hacks.
115 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
116 the module (and would fail if no previous Digest::MD5 was installed).
117 Patch by Mike Stok <mike@stok.co.uk>
121 2002-05-01 Gisle Aas <gisle@ActiveState.com>
125 One more test suite update from Jarkko to sync it
126 even better with bleadperl.
130 2002-05-01 Gisle Aas <gisle@ActiveState.com>
134 Changes #12954 and #16173 from bleadperl. Documentation typo fix
135 and some signed/unsigned mismatches that Microsoft's C compiler
138 The EBCDIC-aware md5-aaa.t from bleadperl.
142 2002-04-25 Gisle Aas <gisle@ActiveState.com>
146 The SvPVbyte in perl-5.6.1 is buggy. Use the one from 5.7.3
149 Give warning if the function interface is used as instance
150 methods: $md5->md5_hex().
154 2001-09-07 Gisle Aas <gisle@ActiveState.com>
158 Sync up with the bleadperl version:
159 - use SvPVbyte() if available
160 - fixes to make the code 'gcc -Wall'-clean
164 2001-08-27 Gisle Aas <gisle@ActiveState.com>
168 Avoid exit() in Makefile.PL and bleadperl redefinition of printf
169 in the alignment test program.
170 Patch by Doug MacEachern <dougm@covalent.net>.
174 2001-07-18 Gisle Aas <gisle@ActiveState.com>
178 Try to warn if the functional interface is used as methods,
179 i.e. Digest::MD5->md5_hex("foo") will make noise if -w is
182 Document the missing padding for the base64 digests.
184 If both XS bootstrap and locating Digest::Perl::MD5 fails
185 re-raise the original XS bootstrap exception.
189 2001-03-13 Gisle Aas <gisle@ActiveState.com>
193 Moved all other Digest:: modules out of the Digest-MD5 dist.

201 Avoid pointer cast warning for machines with bigger ints
202 than pointers. Patch by Robin Barker <rmb1@cise.npl.co.uk>.
206 2000-08-19 Gisle Aas <gisle@ActiveState.com>
210 The fallback code introduced in 2.10 did only work for
211 perl-5.6.0. It should now for for perl5.004 and 5.005
212 as well. Patch by Ville Skyttä <ville@office.popsystems.com>.
216 2000-08-18 Gisle Aas <gisle@ActiveState.com>
220 Digest::MD5 will now try to fallback to the pure perl
221 implementation of Digest::Perl::MD5 if bootstrap fails.
223 Added a bit internal paranoia about casting the IV
224 in the Digest::MD5 object to the MD5_CTX* pointer.
228 1999-08-06 Gisle Aas <gisle@aas.no>
232 Documentation update.
236 1999-07-28 Gisle Aas <gisle@aas.no>
240 The addfile() methods could trigger a core dump when passed
241 a filehandle that had failed to open.
245 1999-04-26 Gisle Aas <gisle@aas.no>
249 The Digest::SHA1 module failed on some 64-bit systems, because I
250 assumed there was a correspondence between the U32 size and
251 BYTEORDER. This version use 'unsigned long' as Uwe's original
254 The module should now work better when liked statically with perl,
255 because we now use a safer module-loaded test in Digest.pm.
257 Assume we know the outcome of the alignment test on VMS. Patch by
258 Chuck Lane <lane@duphy4.physics.drexel.edu>
262 1999-03-26 Gisle Aas <gisle@aas.no>
266 Avoid LONG and BYTE types in SHA.xs as they was in conflict
267 with similar definitions in <winnt.h>.
269 Patch by Marko Asplund <aspa@hip.fi> to make the the alignment
270 test program link successfully with sfio-perl.
272 Fixed a typo in MD5.xs that might have affected 64-bit systems.
273 Spotted by Nick Ing-Simmons
277 1999-03-15 Gisle Aas <gisle@aas.no>
281 Included Digest::SHA1 based on Uwe Hollerbach's SHA module.

290 for Win32 as suggested by Gurusamy Sarathy.
292 DEC Compiler bug workaround. Contributed by D Roland Walker
293 <walker@ncbi.nlm.nih.gov>
295 Having references to a local variable called "na" was not
296 very safe either. Some older versions of Perl can apparently
297 macroize this into something completely different.
301 1999-02-27 Gisle Aas <gisle@aas.no>
305 Patch from Christopher J. Madsen <chris_madsen@geocities.com> that
306 should help getting the u32align test program to compile with
307 Visual C++ 5 on Windows NT.
309 Got rid of references to PL_na.

317 Added a hints file as workaround for an IRIX compiler bug.
318 Contributed by D Roland Walker <walker@ncbi.nlm.nih.gov>.
320 Note that the rfc2202 test can still fail on some DEC Alpha,
321 because of a compiler bug that affects the perl 'x' operator.
322 The Digest:: modules should work and be safe to install anyway.
326 1998-12-18 Gisle Aas <aas@sn.no>
330 Some casts and tweaks to make picky compilers more happy.
334 1998-11-04 Gisle Aas <aas@sn.no>
338 Taken out Digest::SHA1 as this module will be provided from Uwe
341 Some tweaks to MD2.xs and MD5.xs since "na" disappeared in
346 1998-10-30 Gisle Aas <aas@sn.no>
350 The 1.99_59 release introduced compilation problems for big-endian
351 systems with free U32 alignment. Bug reported, and fix suggested
352 by Paul J. Schinder <schinder@pobox.com>.
356 1998-10-28 Gisle Aas <aas@sn.no>
360 Makefile.PL will run a test program to find out if U32 values can
361 be aligned anywhere. This hopefully cures the core dumps reported
362 on Solaris and other big endian systems. Thanks to Graham Barr for
367 1998-10-28 Gisle Aas <aas@sn.no>
371 Should be very close to a 2.00 release now. Need some success
372 reports from people running on big-endian machines first I think.
374 Added a Digest::MD2 implementation.
376 Wrote Digest.pm documentation. This define the interface that all
377 Digest:: modules should provide.
379 Avoided some code duplication in MD5.xs
381 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
385 1998-10-27 Gisle Aas <aas@sn.no>
389 Rewritten most of the MD5 C code to make it real fast (especially
390 on little-endian machines without alignment restrictions for U32).
391 Compared to MD5-1.7 we can process files 4 times as fast and we
392 digest small stuff in memory 7 times faster. I came to these
393 conclusions after these tests (gcc -O2, i586, Linux):
395 First tested calculation of the digest of a 31 MB file, using
396 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
400 Digest::MD5-1.99_57: 5.23s
401 md5sum (GNU textutils): 4.90s
403 As you can see, we do nearly as good as the md5sum program. I
404 think the reason we don't beat md5sum is that perl always insist on
405 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
406 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
407 hasher code in a C program I managed to process the file in 4.68s.
409 Then we calculated the digest of the same 6 byte sting, 20000
413 Digest::MD5-1.99_57: 1.68s
415 Digest::MD5 benefit from making this into a plain procedure call
416 instead of a static method call.
419 Other changes in this release are:
423 Internal MD5.xs cleanup.
425 $md5->digest will automatically reset now.
427 Digest::HMAC methods add() and addfile() did not return the
430 Added Digest.pm loading module. I am not sure this is a good idea.
432 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
433 module is just a wrapper around SHA.pm. I hope to get the author
434 of SHA.pm to move his module to the Digest:: category.
438 1998-10-25 Gisle Aas <aas@sn.no>
442 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
443 htovl() as it might evaluate its arguments more than once.
447 1998-10-25 Gisle Aas <aas@sn.no>
451 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
452 Digest::HMAC_MD5. Also provide functional interface. Documentation
455 Included RFC 2202 based test for HMAC-MD5.
459 1998-10-24 Gisle Aas <aas@sn.no>
463 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
465 I have a hard time to make up my mind :-) md5_bin() renamed back
466 to md5(). Functions are not exported by default any more.
468 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
473 1998-10-23 Gisle Aas <aas@sn.no>
477 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
480 The md5() function renamed as md5_bin().
482 The constructor, Digest::MD5->new, no longer takes any extra
485 Added some new tests.
487 Updated the documentation.
489 $md5->b64digest implemented with same base64 encoder as md5_base64.
493 1998-10-23 Gisle Aas <aas@sn.no>
497 Patch from Graham Barr which make it work for big-endian machines
502 1998-10-22 Gisle Aas <aas@sn.no>
506 The MD5 class is now subclassable.
508 The add() and addfile() methods now return $self.
510 The reset() method is just an alias for new().
512 The constructor (MD5->new) now takes optional arguments which are
513 automatically added. It means that we can now write:
515 MD5->new($data)->hexdigest;
517 New $md5->b64digest method.
519 New functions that are exported on request: md5, md5_hex, md5_base64
523 Barely started to update the documentation.
527 1998-10-22 Gisle Aas <aas@sn.no>
531 Much better performance (more than twice as fast now). Mostly
532 because we use Copy/Zero instead of the original MD5_memcpy and
533 MD5_memset functions.
535 The addfile() and hexdigest() methods are now XS implemented.
537 All RSA functions now included in MD5.xs and made static.
539 Use perl's Copy/Zero.
541 Random cleanup, simplifications and reformatting.
542 Merged things better with the perl configuration.
546 Neil Winton's versions below:
549 *** 96/06/20 Version 1.7
551 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
552 32-bit quantities and requires a typedef UINT4 to be defined in
553 global.h. Perl configuration data (the value of BYTEORDER) is used to
554 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
555 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
556 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
557 Makefile.PL will override this.
559 On some machines (at least Cray that I know of) there is no 32-bit
560 integer type. In this case defining TRUNCATE_UINT4 (which is done
561 automatically for a Cray) will ensure that 64-bit values are masked
562 down to 32 bits. I have done my best to test this but without easy
563 access to a true 64-bit machine I can not totally guarantee it (unless
564 anyone wants to lend me a spare Cray :-)
566 There is one remaining limitation for 64-bit enabled processors. The
567 amount of data passed to any single call to the underlying MD5
568 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
569 sorry if that's a real problem for you ...
571 And finally, a minor compilation warning (unsigned char * used with
572 function having char * prototype) has also been eliminated.
574 *** 96/04/09 Version 1.6
576 Re-generated module framework using h2xs to pick up the latest module
577 conventions for versions etc. You can now say "use MD5 1.6;" and things
578 should work correctly. MD5.pod has been integrated into MD5.pm and
579 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
580 which can be invoked via "make test". There are no functional changes
581 to the MD5 routines themselves.
583 *** 96/03/14 Version 1.5.3
585 Fixed addfile method to accept type-glob references for the file-handle
586 (eg \*STDOUT). This is more consistent with other routines and is now the
587 recommended way of passing file-handles. The documentation now gives more
588 examples as to how the routines might be used.
590 *** 96/03/12 Version 1.5.2
592 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
593 support for building on OS/2 (and to work around a perl -w bug).
595 Remove warning about possible difference between add('foo', 'bar') and
596 add('foobar'). This is not true (it may have been true in the earliest
597 version of the module but is no longer the case).
599 *** 96/03/08 Version 1.5.1
601 Add CHANGES file to make it easier for people to figure out what has
602 been going on. (Meant to do this as part of 1.5)
604 *** 96/03/05 Version 1.5
606 Add hash() and hexhash() methods at the suggestion/request of Gary
607 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
608 of cryptography modules.
610 *** 96/02/27 Version 1.4
612 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
613 Pizzini <kenp@spry.com>!
615 *** 95/11/29 Version 1.3.1
617 Add explanations of current known problems.
619 *** 95/06/02 Version 1.3
621 Fix problems with scope resolution in addfile() reported by
622 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
623 always implicitly in package main while other filehandles aren't.
625 *** 95/05/23 Version 1.2.1
627 [Changes pre 1.2.1 not recorded]
