112 Don't assume PerlIO_read() works like fread() even though
113 it was documented like that for perl 5.6. It returns negative
116 Kill test #3 in t/badfile.t. I don't know a reliable way
117 to test read failures on a file handle. Seems better not to
118 test than to make many worry.
122 2003-07-04 Gisle Aas <gisle@ActiveState.com>
126 The $md5->addfile method now croaks if it discovers
127 errors on the handle after reading from it. This should
128 make it more difficult to end up with the wrong digest
129 just because you are to lazy to check the error status
130 on your file handles after reading from them.
132 Improved documentation.
134 Sync up with bleadperl; even safer patchlevel include.

170 Minor tweaks sync up with bleadperl:
171 - VMS optimizer tweaks to the Makefile.PL
173 - Added alignment test
175 Added example to the MD5 POD that shows how to calculate the
176 digest of Unicode strings.
180 2002-05-05 Gisle Aas <gisle@ActiveState.com>
184 More synchronization with tweaks Jarkko have done to the
185 bleadperl test suite. This time various EBCDIC hacks.
187 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
188 the module (and would fail if no previous Digest::MD5 was installed).

428 1998-10-28 Gisle Aas <aas@sn.no>
432 Makefile.PL will run a test program to find out if U32 values can
433 be aligned anywhere. This hopefully cures the core dumps reported
434 on Solaris and other big endian systems. Thanks to Graham Barr for
439 1998-10-28 Gisle Aas <aas@sn.no>
443 Should be very close to a 2.00 release now. Need some success
444 reports from people running on big-endian machines first I think.
446 Added a Digest::MD2 implementation.
448 Wrote Digest.pm documentation. This define the interface that all
449 Digest:: modules should provide.
451 Avoided some code duplication in MD5.xs
453 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
457 1998-10-27 Gisle Aas <aas@sn.no>
461 Rewritten most of the MD5 C code to make it real fast (especially
462 on little-endian machines without alignment restrictions for U32).
463 Compared to MD5-1.7 we can process files 4 times as fast and we
464 digest small stuff in memory 7 times faster. I came to these
465 conclusions after these tests (gcc -O2, i586, Linux):
467 First tested calculation of the digest of a 31 MB file, using
468 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
472 Digest::MD5-1.99_57: 5.23s
473 md5sum (GNU textutils): 4.90s
475 As you can see, we do nearly as good as the md5sum program. I
476 think the reason we don't beat md5sum is that perl always insist on
477 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
478 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
479 hasher code in a C program I managed to process the file in 4.68s.
481 Then we calculated the digest of the same 6 byte sting, 20000
485 Digest::MD5-1.99_57: 1.68s
487 Digest::MD5 benefit from making this into a plain procedure call
488 instead of a static method call.
491 Other changes in this release are:
495 Internal MD5.xs cleanup.
497 $md5->digest will automatically reset now.
499 Digest::HMAC methods add() and addfile() did not return the
502 Added Digest.pm loading module. I am not sure this is a good idea.
504 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
505 module is just a wrapper around SHA.pm. I hope to get the author
506 of SHA.pm to move his module to the Digest:: category.
510 1998-10-25 Gisle Aas <aas@sn.no>
514 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
515 htovl() as it might evaluate its arguments more than once.
519 1998-10-25 Gisle Aas <aas@sn.no>
523 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
524 Digest::HMAC_MD5. Also provide functional interface. Documentation
527 Included RFC 2202 based test for HMAC-MD5.
531 1998-10-24 Gisle Aas <aas@sn.no>
535 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
537 I have a hard time to make up my mind :-) md5_bin() renamed back
538 to md5(). Functions are not exported by default any more.
540 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
545 1998-10-23 Gisle Aas <aas@sn.no>
549 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
552 The md5() function renamed as md5_bin().
554 The constructor, Digest::MD5->new, no longer takes any extra
557 Added some new tests.
559 Updated the documentation.
561 $md5->b64digest implemented with same base64 encoder as md5_base64.
565 1998-10-23 Gisle Aas <aas@sn.no>
569 Patch from Graham Barr which make it work for big-endian machines
574 1998-10-22 Gisle Aas <aas@sn.no>
578 The MD5 class is now subclassable.
580 The add() and addfile() methods now return $self.
582 The reset() method is just an alias for new().
584 The constructor (MD5->new) now takes optional arguments which are
585 automatically added. It means that we can now write:
587 MD5->new($data)->hexdigest;
589 New $md5->b64digest method.
591 New functions that are exported on request: md5, md5_hex, md5_base64
595 Barely started to update the documentation.
599 1998-10-22 Gisle Aas <aas@sn.no>
603 Much better performance (more than twice as fast now). Mostly
604 because we use Copy/Zero instead of the original MD5_memcpy and
605 MD5_memset functions.
607 The addfile() and hexdigest() methods are now XS implemented.
609 All RSA functions now included in MD5.xs and made static.
611 Use perl's Copy/Zero.
613 Random cleanup, simplifications and reformatting.
614 Merged things better with the perl configuration.
618 Neil Winton's versions below:
621 *** 96/06/20 Version 1.7
623 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
624 32-bit quantities and requires a typedef UINT4 to be defined in
625 global.h. Perl configuration data (the value of BYTEORDER) is used to
626 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
627 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
628 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
629 Makefile.PL will override this.
631 On some machines (at least Cray that I know of) there is no 32-bit
632 integer type. In this case defining TRUNCATE_UINT4 (which is done
633 automatically for a Cray) will ensure that 64-bit values are masked
634 down to 32 bits. I have done my best to test this but without easy
635 access to a true 64-bit machine I can not totally guarantee it (unless
636 anyone wants to lend me a spare Cray :-)
638 There is one remaining limitation for 64-bit enabled processors. The
639 amount of data passed to any single call to the underlying MD5
640 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
641 sorry if that's a real problem for you ...
643 And finally, a minor compilation warning (unsigned char * used with
644 function having char * prototype) has also been eliminated.
646 *** 96/04/09 Version 1.6
648 Re-generated module framework using h2xs to pick up the latest module
649 conventions for versions etc. You can now say "use MD5 1.6;" and things
650 should work correctly. MD5.pod has been integrated into MD5.pm and
651 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
652 which can be invoked via "make test". There are no functional changes
653 to the MD5 routines themselves.
655 *** 96/03/14 Version 1.5.3
657 Fixed addfile method to accept type-glob references for the file-handle
658 (eg \*STDOUT). This is more consistent with other routines and is now the
659 recommended way of passing file-handles. The documentation now gives more
660 examples as to how the routines might be used.
662 *** 96/03/12 Version 1.5.2
664 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
665 support for building on OS/2 (and to work around a perl -w bug).
667 Remove warning about possible difference between add('foo', 'bar') and
668 add('foobar'). This is not true (it may have been true in the earliest
669 version of the module but is no longer the case).
671 *** 96/03/08 Version 1.5.1
673 Add CHANGES file to make it easier for people to figure out what has
674 been going on. (Meant to do this as part of 1.5)
676 *** 96/03/05 Version 1.5
678 Add hash() and hexhash() methods at the suggestion/request of Gary
679 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
680 of cryptography modules.
682 *** 96/02/27 Version 1.4
684 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
685 Pizzini <kenp@spry.com>!
687 *** 95/11/29 Version 1.3.1
689 Add explanations of current known problems.
691 *** 95/06/02 Version 1.3
693 Fix problems with scope resolution in addfile() reported by
694 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
695 always implicitly in package main while other filehandles aren't.
697 *** 95/05/23 Version 1.2.1
699 [Changes pre 1.2.1 not recorded]
