38 Avoid having to figure how to compile alignment test program
39 on MS-Windows by just assume free alignment as for i386. Source
40 builds on Windows was apparently broken.
44 2003-07-21 Gisle Aas <gisle@ActiveState.com>
48 Don't assume PerlIO_read() works like fread() even though
49 it was documented like that for perl 5.6. It returns negative
52 Kill test #3 in t/badfile.t. I don't know a reliable way
53 to test read failures on a file handle. Seems better not to
54 test than to make many worry.
58 2003-07-04 Gisle Aas <gisle@ActiveState.com>
62 The $md5->addfile method now croaks if it discovers
63 errors on the handle after reading from it. This should
64 make it more difficult to end up with the wrong digest
65 just because you are to lazy to check the error status
66 on your file handles after reading from them.
68 Improved documentation.

106 Minor tweaks sync up with bleadperl:
107 - VMS optimizer tweaks to the Makefile.PL
109 - Added alignment test
111 Added example to the MD5 POD that shows how to calculate the
112 digest of Unicode strings.
116 2002-05-05 Gisle Aas <gisle@ActiveState.com>
120 More synchronization with tweaks Jarkko have done to the
121 bleadperl test suite. This time various EBCDIC hacks.
123 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
124 the module (and would fail if no previous Digest::MD5 was installed).

358 The 1.99_59 release introduced compilation problems for big-endian
359 systems with free U32 alignment. Bug reported, and fix suggested
360 by Paul J. Schinder <schinder@pobox.com>.
364 1998-10-28 Gisle Aas <aas@sn.no>
368 Makefile.PL will run a test program to find out if U32 values can
369 be aligned anywhere. This hopefully cures the core dumps reported
370 on Solaris and other big endian systems. Thanks to Graham Barr for
375 1998-10-28 Gisle Aas <aas@sn.no>
379 Should be very close to a 2.00 release now. Need some success
380 reports from people running on big-endian machines first I think.
382 Added a Digest::MD2 implementation.
384 Wrote Digest.pm documentation. This define the interface that all
385 Digest:: modules should provide.
387 Avoided some code duplication in MD5.xs
389 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
393 1998-10-27 Gisle Aas <aas@sn.no>
397 Rewritten most of the MD5 C code to make it real fast (especially
398 on little-endian machines without alignment restrictions for U32).
399 Compared to MD5-1.7 we can process files 4 times as fast and we
400 digest small stuff in memory 7 times faster. I came to these
401 conclusions after these tests (gcc -O2, i586, Linux):
403 First tested calculation of the digest of a 31 MB file, using
404 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
408 Digest::MD5-1.99_57: 5.23s
409 md5sum (GNU textutils): 4.90s
411 As you can see, we do nearly as good as the md5sum program. I
412 think the reason we don't beat md5sum is that perl always insist on
413 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
414 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
415 hasher code in a C program I managed to process the file in 4.68s.
417 Then we calculated the digest of the same 6 byte sting, 20000
421 Digest::MD5-1.99_57: 1.68s
423 Digest::MD5 benefit from making this into a plain procedure call
424 instead of a static method call.
427 Other changes in this release are:
431 Internal MD5.xs cleanup.
433 $md5->digest will automatically reset now.
435 Digest::HMAC methods add() and addfile() did not return the
438 Added Digest.pm loading module. I am not sure this is a good idea.
440 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
441 module is just a wrapper around SHA.pm. I hope to get the author
442 of SHA.pm to move his module to the Digest:: category.
446 1998-10-25 Gisle Aas <aas@sn.no>
450 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
451 htovl() as it might evaluate its arguments more than once.
455 1998-10-25 Gisle Aas <aas@sn.no>
459 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
460 Digest::HMAC_MD5. Also provide functional interface. Documentation
463 Included RFC 2202 based test for HMAC-MD5.
467 1998-10-24 Gisle Aas <aas@sn.no>
471 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
473 I have a hard time to make up my mind :-) md5_bin() renamed back
474 to md5(). Functions are not exported by default any more.
476 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
481 1998-10-23 Gisle Aas <aas@sn.no>
485 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
488 The md5() function renamed as md5_bin().
490 The constructor, Digest::MD5->new, no longer takes any extra
493 Added some new tests.
495 Updated the documentation.
497 $md5->b64digest implemented with same base64 encoder as md5_base64.
501 1998-10-23 Gisle Aas <aas@sn.no>
505 Patch from Graham Barr which make it work for big-endian machines
510 1998-10-22 Gisle Aas <aas@sn.no>
514 The MD5 class is now subclassable.
516 The add() and addfile() methods now return $self.
518 The reset() method is just an alias for new().
520 The constructor (MD5->new) now takes optional arguments which are
521 automatically added. It means that we can now write:
523 MD5->new($data)->hexdigest;
525 New $md5->b64digest method.
527 New functions that are exported on request: md5, md5_hex, md5_base64
531 Barely started to update the documentation.
535 1998-10-22 Gisle Aas <aas@sn.no>
539 Much better performance (more than twice as fast now). Mostly
540 because we use Copy/Zero instead of the original MD5_memcpy and
541 MD5_memset functions.
543 The addfile() and hexdigest() methods are now XS implemented.
545 All RSA functions now included in MD5.xs and made static.
547 Use perl's Copy/Zero.
549 Random cleanup, simplifications and reformatting.
550 Merged things better with the perl configuration.
554 Neil Winton's versions below:
557 *** 96/06/20 Version 1.7
559 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
560 32-bit quantities and requires a typedef UINT4 to be defined in
561 global.h. Perl configuration data (the value of BYTEORDER) is used to
562 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
563 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
564 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
565 Makefile.PL will override this.
567 On some machines (at least Cray that I know of) there is no 32-bit
568 integer type. In this case defining TRUNCATE_UINT4 (which is done
569 automatically for a Cray) will ensure that 64-bit values are masked
570 down to 32 bits. I have done my best to test this but without easy
571 access to a true 64-bit machine I can not totally guarantee it (unless
572 anyone wants to lend me a spare Cray :-)
574 There is one remaining limitation for 64-bit enabled processors. The
575 amount of data passed to any single call to the underlying MD5
576 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
577 sorry if that's a real problem for you ...
579 And finally, a minor compilation warning (unsigned char * used with
580 function having char * prototype) has also been eliminated.
582 *** 96/04/09 Version 1.6
584 Re-generated module framework using h2xs to pick up the latest module
585 conventions for versions etc. You can now say "use MD5 1.6;" and things
586 should work correctly. MD5.pod has been integrated into MD5.pm and
587 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
588 which can be invoked via "make test". There are no functional changes
589 to the MD5 routines themselves.
591 *** 96/03/14 Version 1.5.3
593 Fixed addfile method to accept type-glob references for the file-handle
594 (eg \*STDOUT). This is more consistent with other routines and is now the
595 recommended way of passing file-handles. The documentation now gives more
596 examples as to how the routines might be used.
598 *** 96/03/12 Version 1.5.2
600 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
601 support for building on OS/2 (and to work around a perl -w bug).
603 Remove warning about possible difference between add('foo', 'bar') and
604 add('foobar'). This is not true (it may have been true in the earliest
605 version of the module but is no longer the case).
607 *** 96/03/08 Version 1.5.1
609 Add CHANGES file to make it easier for people to figure out what has
610 been going on. (Meant to do this as part of 1.5)
612 *** 96/03/05 Version 1.5
614 Add hash() and hexhash() methods at the suggestion/request of Gary
615 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
616 of cryptography modules.
618 *** 96/02/27 Version 1.4
620 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
621 Pizzini <kenp@spry.com>!
623 *** 95/11/29 Version 1.3.1
625 Add explanations of current known problems.
627 *** 95/06/02 Version 1.3
629 Fix problems with scope resolution in addfile() reported by
630 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
631 always implicitly in package main while other filehandles aren't.
633 *** 95/05/23 Version 1.2.1
635 [Changes pre 1.2.1 not recorded]
