104 Don't assume PerlIO_read() works like fread() even though
105 it was documented like that for perl 5.6. It returns negative
108 Kill test #3 in t/badfile.t. I don't know a reliable way
109 to test read failures on a file handle. Seems better not to
110 test than to make many worry.

118 The $md5->addfile method now croaks if it discovers
119 errors on the handle after reading from it. This should
120 make it more difficult to end up with the wrong digest
121 just because you are to lazy to check the error status
122 on your file handles after reading from them.

420 1998-10-28 Gisle Aas <aas@sn.no>
424 Makefile.PL will run a test program to find out if U32 values can
425 be aligned anywhere. This hopefully cures the core dumps reported
426 on Solaris and other big endian systems. Thanks to Graham Barr for
431 1998-10-28 Gisle Aas <aas@sn.no>
435 Should be very close to a 2.00 release now. Need some success
436 reports from people running on big-endian machines first I think.
438 Added a Digest::MD2 implementation.
440 Wrote Digest.pm documentation. This define the interface that all
441 Digest:: modules should provide.
443 Avoided some code duplication in MD5.xs
445 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
449 1998-10-27 Gisle Aas <aas@sn.no>
453 Rewritten most of the MD5 C code to make it real fast (especially
454 on little-endian machines without alignment restrictions for U32).
455 Compared to MD5-1.7 we can process files 4 times as fast and we
456 digest small stuff in memory 7 times faster. I came to these
457 conclusions after these tests (gcc -O2, i586, Linux):
459 First tested calculation of the digest of a 31 MB file, using
460 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
464 Digest::MD5-1.99_57: 5.23s
465 md5sum (GNU textutils): 4.90s
467 As you can see, we do nearly as good as the md5sum program. I
468 think the reason we don't beat md5sum is that perl always insist on
469 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
470 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
471 hasher code in a C program I managed to process the file in 4.68s.
473 Then we calculated the digest of the same 6 byte sting, 20000
477 Digest::MD5-1.99_57: 1.68s
479 Digest::MD5 benefit from making this into a plain procedure call
480 instead of a static method call.
483 Other changes in this release are:
487 Internal MD5.xs cleanup.
489 $md5->digest will automatically reset now.
491 Digest::HMAC methods add() and addfile() did not return the
494 Added Digest.pm loading module. I am not sure this is a good idea.
496 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
497 module is just a wrapper around SHA.pm. I hope to get the author
498 of SHA.pm to move his module to the Digest:: category.

506 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
507 htovl() as it might evaluate its arguments more than once.
511 1998-10-25 Gisle Aas <aas@sn.no>
515 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
516 Digest::HMAC_MD5. Also provide functional interface. Documentation
519 Included RFC 2202 based test for HMAC-MD5.

527 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
529 I have a hard time to make up my mind :-) md5_bin() renamed back

549 Added some new tests.
551 Updated the documentation.
553 $md5->b64digest implemented with same base64 encoder as md5_base64.

561 Patch from Graham Barr which make it work for big-endian machines
566 1998-10-22 Gisle Aas <aas@sn.no>
570 The MD5 class is now subclassable.
572 The add() and addfile() methods now return $self.
574 The reset() method is just an alias for new().
576 The constructor (MD5->new) now takes optional arguments which are
577 automatically added. It means that we can now write:
579 MD5->new($data)->hexdigest;
581 New $md5->b64digest method.
583 New functions that are exported on request: md5, md5_hex, md5_base64
587 Barely started to update the documentation.
591 1998-10-22 Gisle Aas <aas@sn.no>
595 Much better performance (more than twice as fast now). Mostly
596 because we use Copy/Zero instead of the original MD5_memcpy and
597 MD5_memset functions.
599 The addfile() and hexdigest() methods are now XS implemented.
601 All RSA functions now included in MD5.xs and made static.
603 Use perl's Copy/Zero.
605 Random cleanup, simplifications and reformatting.
606 Merged things better with the perl configuration.
610 Neil Winton's versions below:
613 *** 96/06/20 Version 1.7
615 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
616 32-bit quantities and requires a typedef UINT4 to be defined in
617 global.h. Perl configuration data (the value of BYTEORDER) is used to
618 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
619 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
620 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
621 Makefile.PL will override this.
623 On some machines (at least Cray that I know of) there is no 32-bit
624 integer type. In this case defining TRUNCATE_UINT4 (which is done
625 automatically for a Cray) will ensure that 64-bit values are masked
626 down to 32 bits. I have done my best to test this but without easy
627 access to a true 64-bit machine I can not totally guarantee it (unless
628 anyone wants to lend me a spare Cray :-)
630 There is one remaining limitation for 64-bit enabled processors. The
631 amount of data passed to any single call to the underlying MD5
632 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
633 sorry if that's a real problem for you ...
635 And finally, a minor compilation warning (unsigned char * used with
636 function having char * prototype) has also been eliminated.
638 *** 96/04/09 Version 1.6
640 Re-generated module framework using h2xs to pick up the latest module
641 conventions for versions etc. You can now say "use MD5 1.6;" and things
642 should work correctly. MD5.pod has been integrated into MD5.pm and
643 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
644 which can be invoked via "make test". There are no functional changes
645 to the MD5 routines themselves.
647 *** 96/03/14 Version 1.5.3
649 Fixed addfile method to accept type-glob references for the file-handle
650 (eg \*STDOUT). This is more consistent with other routines and is now the
651 recommended way of passing file-handles. The documentation now gives more
652 examples as to how the routines might be used.
654 *** 96/03/12 Version 1.5.2
656 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
657 support for building on OS/2 (and to work around a perl -w bug).
659 Remove warning about possible difference between add('foo', 'bar') and
660 add('foobar'). This is not true (it may have been true in the earliest
661 version of the module but is no longer the case).
663 *** 96/03/08 Version 1.5.1
665 Add CHANGES file to make it easier for people to figure out what has
666 been going on. (Meant to do this as part of 1.5)
668 *** 96/03/05 Version 1.5
670 Add hash() and hexhash() methods at the suggestion/request of Gary
671 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
672 of cryptography modules.
674 *** 96/02/27 Version 1.4
676 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
677 Pizzini <kenp@spry.com>!
679 *** 95/11/29 Version 1.3.1
681 Add explanations of current known problems.
683 *** 95/06/02 Version 1.3
685 Fix problems with scope resolution in addfile() reported by
686 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
687 always implicitly in package main while other filehandles aren't.
689 *** 95/05/23 Version 1.2.1
691 [Changes pre 1.2.1 not recorded]
