5 Avoid having to figure how to compile alignment test program

15 Don't assume PerlIO_read() works like fread() even though
16 it was documented like that for perl 5.6. It returns negative
19 Kill test #3 in t/badfile.t. I don't know a reliable way
20 to test read failures on a file handle. Seems better not to
21 test than to make many worry.
25 2003-07-04 Gisle Aas <gisle@ActiveState.com>
29 The $md5->addfile method now croaks if it discovers
30 errors on the handle after reading from it. This should
31 make it more difficult to end up with the wrong digest
32 just because you are to lazy to check the error status
33 on your file handles after reading from them.
35 Improved documentation.

73 Minor tweaks sync up with bleadperl:
74 - VMS optimizer tweaks to the Makefile.PL
76 - Added alignment test
78 Added example to the MD5 POD that shows how to calculate the
79 digest of Unicode strings.
83 2002-05-05 Gisle Aas <gisle@ActiveState.com>
87 More synchronization with tweaks Jarkko have done to the
88 bleadperl test suite. This time various EBCDIC hacks.
90 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
91 the module (and would fail if no previous Digest::MD5 was installed).

325 The 1.99_59 release introduced compilation problems for big-endian

331 1998-10-28 Gisle Aas <aas@sn.no>
335 Makefile.PL will run a test program to find out if U32 values can
336 be aligned anywhere. This hopefully cures the core dumps reported
337 on Solaris and other big endian systems. Thanks to Graham Barr for
342 1998-10-28 Gisle Aas <aas@sn.no>
346 Should be very close to a 2.00 release now. Need some success
347 reports from people running on big-endian machines first I think.
349 Added a Digest::MD2 implementation.
351 Wrote Digest.pm documentation. This define the interface that all
352 Digest:: modules should provide.
354 Avoided some code duplication in MD5.xs
356 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
360 1998-10-27 Gisle Aas <aas@sn.no>
364 Rewritten most of the MD5 C code to make it real fast (especially
365 on little-endian machines without alignment restrictions for U32).
366 Compared to MD5-1.7 we can process files 4 times as fast and we
367 digest small stuff in memory 7 times faster. I came to these
368 conclusions after these tests (gcc -O2, i586, Linux):
370 First tested calculation of the digest of a 31 MB file, using
371 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
375 Digest::MD5-1.99_57: 5.23s
376 md5sum (GNU textutils): 4.90s
378 As you can see, we do nearly as good as the md5sum program. I
379 think the reason we don't beat md5sum is that perl always insist on
380 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
381 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
382 hasher code in a C program I managed to process the file in 4.68s.
384 Then we calculated the digest of the same 6 byte sting, 20000
388 Digest::MD5-1.99_57: 1.68s
390 Digest::MD5 benefit from making this into a plain procedure call
391 instead of a static method call.
394 Other changes in this release are:
398 Internal MD5.xs cleanup.
400 $md5->digest will automatically reset now.
402 Digest::HMAC methods add() and addfile() did not return the
405 Added Digest.pm loading module. I am not sure this is a good idea.
407 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
408 module is just a wrapper around SHA.pm. I hope to get the author
409 of SHA.pm to move his module to the Digest:: category.
413 1998-10-25 Gisle Aas <aas@sn.no>
417 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
418 htovl() as it might evaluate its arguments more than once.
422 1998-10-25 Gisle Aas <aas@sn.no>
426 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
427 Digest::HMAC_MD5. Also provide functional interface. Documentation
430 Included RFC 2202 based test for HMAC-MD5.
434 1998-10-24 Gisle Aas <aas@sn.no>
438 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
440 I have a hard time to make up my mind :-) md5_bin() renamed back
441 to md5(). Functions are not exported by default any more.
443 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
448 1998-10-23 Gisle Aas <aas@sn.no>
452 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
455 The md5() function renamed as md5_bin().
457 The constructor, Digest::MD5->new, no longer takes any extra
460 Added some new tests.
462 Updated the documentation.
464 $md5->b64digest implemented with same base64 encoder as md5_base64.
468 1998-10-23 Gisle Aas <aas@sn.no>
472 Patch from Graham Barr which make it work for big-endian machines
477 1998-10-22 Gisle Aas <aas@sn.no>
481 The MD5 class is now subclassable.
483 The add() and addfile() methods now return $self.
485 The reset() method is just an alias for new().
487 The constructor (MD5->new) now takes optional arguments which are
488 automatically added. It means that we can now write:
490 MD5->new($data)->hexdigest;
492 New $md5->b64digest method.
494 New functions that are exported on request: md5, md5_hex, md5_base64
498 Barely started to update the documentation.
502 1998-10-22 Gisle Aas <aas@sn.no>
506 Much better performance (more than twice as fast now). Mostly
507 because we use Copy/Zero instead of the original MD5_memcpy and
508 MD5_memset functions.
510 The addfile() and hexdigest() methods are now XS implemented.
512 All RSA functions now included in MD5.xs and made static.
514 Use perl's Copy/Zero.
516 Random cleanup, simplifications and reformatting.
517 Merged things better with the perl configuration.
521 Neil Winton's versions below:
524 *** 96/06/20 Version 1.7
526 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
527 32-bit quantities and requires a typedef UINT4 to be defined in
528 global.h. Perl configuration data (the value of BYTEORDER) is used to
529 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
530 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
531 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
532 Makefile.PL will override this.
534 On some machines (at least Cray that I know of) there is no 32-bit
535 integer type. In this case defining TRUNCATE_UINT4 (which is done
536 automatically for a Cray) will ensure that 64-bit values are masked
537 down to 32 bits. I have done my best to test this but without easy
538 access to a true 64-bit machine I can not totally guarantee it (unless
539 anyone wants to lend me a spare Cray :-)
541 There is one remaining limitation for 64-bit enabled processors. The
542 amount of data passed to any single call to the underlying MD5
543 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
544 sorry if that's a real problem for you ...
546 And finally, a minor complilation warning (unsigned char * used with
547 function having char * prototype) has also been eliminated.
549 *** 96/04/09 Version 1.6
551 Re-generated module framework using h2xs to pick up the latest module
552 conventions for versions etc. You can now say "use MD5 1.6;" and things
553 should work correctly. MD5.pod has been integrated into MD5.pm and
554 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
555 which can be invoked via "make test". There are no functional changes
556 to the MD5 routines themselves.
558 *** 96/03/14 Version 1.5.3
560 Fixed addfile method to accept type-glob references for the file-handle
561 (eg \*STDOUT). This is more consistent with other routines and is now the
562 recommended way of passing file-handles. The documentation now gives more
563 examples as to how the routines might be used.
565 *** 96/03/12 Version 1.5.2
567 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
568 support for building on OS/2 (and to work arround a perl -w bug).
570 Remove warning about possible difference between add('foo', 'bar') and
571 add('foobar'). This is not true (it may have been true in the earliest
572 version of the module but is no longer the case).
574 *** 96/03/08 Version 1.5.1
576 Add CHANGES file to make it easier for people to figure out what has
577 been going on. (Meant to do this as part of 1.5)
579 *** 96/03/05 Version 1.5
581 Add hash() and hexhash() methods at the suggestion/request of Gary
582 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
583 of cryptography modules.
585 *** 96/02/27 Version 1.4
587 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
588 Pizzini <kenp@spry.com>!
590 *** 95/11/29 Version 1.3.1
592 Add explanations of current known problems.
594 *** 95/06/02 Version 1.3
596 Fix problems with scope resolution in addfile() reported by
597 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
598 always implicitly in package main while other filehandles aren't.
600 *** 95/05/23 Version 1.2.1
602 [Changes pre 1.2.1 not recorded]
