5 The $md5->addfile method now croaks if it discovers
6 errors on the handle after reading from it. This should
7 make it more difficult to end up with the wrong digest
8 just because you are to lazy to check the error status
9 on your file handles after reading from them.
11 Improved documentation.

49 Minor tweaks sync up with bleadperl:
50 - VMS optimizer tweaks to the Makefile.PL
52 - Added alignment test
54 Added example to the MD5 POD that shows how to calculate the
55 digest of Unicode strings.
59 2002-05-05 Gisle Aas <gisle@ActiveState.com>
63 More synchronization with tweaks Jarkko have done to the
64 bleadperl test suite. This time various EBCDIC hacks.
66 Outside PERL_CORE the md5-aaa.t test loaded the wrong version of
67 the module (and would fail if no previous Digest::MD5 was installed).

243 DEC Compiler bug workaround. Contributed by D Roland Walker
244 <walker@ncbi.nlm.nih.gov>
246 Having references to a local variable called "na" was not
247 very safe either. Some older versions of Perl can apparently
248 macroize this into something completely different.

301 The 1.99_59 release introduced compilation problems for big-endian
302 systems with free U32 alignment. Bug reported, and fix suggested
303 by Paul J. Schinder <schinder@pobox.com>.
307 1998-10-28 Gisle Aas <aas@sn.no>
311 Makefile.PL will run a test program to find out if U32 values can
312 be aligned anywhere. This hopefully cures the core dumps reported
313 on Solaris and other big endian systems. Thanks to Graham Barr for
318 1998-10-28 Gisle Aas <aas@sn.no>
322 Should be very close to a 2.00 release now. Need some success
323 reports from people running on big-endian machines first I think.
325 Added a Digest::MD2 implementation.
327 Wrote Digest.pm documentation. This define the interface that all
328 Digest:: modules should provide.
330 Avoided some code duplication in MD5.xs
332 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
336 1998-10-27 Gisle Aas <aas@sn.no>
340 Rewritten most of the MD5 C code to make it real fast (especially
341 on little-endian machines without alignment restrictions for U32).
342 Compared to MD5-1.7 we can process files 4 times as fast and we
343 digest small stuff in memory 7 times faster. I came to these
344 conclusions after these tests (gcc -O2, i586, Linux):
346 First tested calculation of the digest of a 31 MB file, using
347 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
351 Digest::MD5-1.99_57: 5.23s
352 md5sum (GNU textutils): 4.90s
354 As you can see, we do nearly as good as the md5sum program. I
355 think the reason we don't beat md5sum is that perl always insist on
356 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
357 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
358 hasher code in a C program I managed to process the file in 4.68s.
360 Then we calculated the digest of the same 6 byte sting, 20000
364 Digest::MD5-1.99_57: 1.68s
366 Digest::MD5 benefit from making this into a plain procedure call
367 instead of a static method call.
370 Other changes in this release are:
374 Internal MD5.xs cleanup.
376 $md5->digest will automatically reset now.
378 Digest::HMAC methods add() and addfile() did not return the
381 Added Digest.pm loading module. I am not sure this is a good idea.
383 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
384 module is just a wrapper around SHA.pm. I hope to get the author
385 of SHA.pm to move his module to the Digest:: category.
389 1998-10-25 Gisle Aas <aas@sn.no>
393 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
394 htovl() as it might evaluate its arguments more than once.
398 1998-10-25 Gisle Aas <aas@sn.no>
402 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
403 Digest::HMAC_MD5. Also provide functional interface. Documentation
406 Included RFC 2202 based test for HMAC-MD5.
410 1998-10-24 Gisle Aas <aas@sn.no>
414 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
416 I have a hard time to make up my mind :-) md5_bin() renamed back
417 to md5(). Functions are not exported by default any more.
419 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
424 1998-10-23 Gisle Aas <aas@sn.no>
428 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
431 The md5() function renamed as md5_bin().
433 The constructor, Digest::MD5->new, no longer takes any extra
436 Added some new tests.
438 Updated the documentation.
440 $md5->b64digest implemented with same base64 encoder as md5_base64.
444 1998-10-23 Gisle Aas <aas@sn.no>
448 Patch from Graham Barr which make it work for big-endian machines
453 1998-10-22 Gisle Aas <aas@sn.no>
457 The MD5 class is now subclassable.
459 The add() and addfile() methods now return $self.
461 The reset() method is just an alias for new().
463 The constructor (MD5->new) now takes optional arguments which are
464 automatically added. It means that we can now write:
466 MD5->new($data)->hexdigest;
468 New $md5->b64digest method.
470 New functions that are exported on request: md5, md5_hex, md5_base64
474 Barely started to update the documentation.
478 1998-10-22 Gisle Aas <aas@sn.no>
482 Much better performance (more than twice as fast now). Mostly
483 because we use Copy/Zero instead of the original MD5_memcpy and
484 MD5_memset functions.
486 The addfile() and hexdigest() methods are now XS implemented.
488 All RSA functions now included in MD5.xs and made static.
490 Use perl's Copy/Zero.
492 Random cleanup, simplifications and reformatting.
493 Merged things better with the perl configuration.
497 Neil Winton's versions below:
500 *** 96/06/20 Version 1.7
502 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
503 32-bit quantities and requires a typedef UINT4 to be defined in
504 global.h. Perl configuration data (the value of BYTEORDER) is used to
505 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
506 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
507 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
508 Makefile.PL will override this.
510 On some machines (at least Cray that I know of) there is no 32-bit
511 integer type. In this case defining TRUNCATE_UINT4 (which is done
512 automatically for a Cray) will ensure that 64-bit values are masked
513 down to 32 bits. I have done my best to test this but without easy
514 access to a true 64-bit machine I can not totally guarantee it (unless
515 anyone wants to lend me a spare Cray :-)
517 There is one remaining limitation for 64-bit enabled processors. The
518 amount of data passed to any single call to the underlying MD5
519 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
520 sorry if that's a real problem for you ...
522 And finally, a minor complilation warning (unsigned char * used with
523 function having char * prototype) has also been eliminated.
525 *** 96/04/09 Version 1.6
527 Re-generated module framework using h2xs to pick up the latest module
528 conventions for versions etc. You can now say "use MD5 1.6;" and things
529 should work correctly. MD5.pod has been integrated into MD5.pm and
530 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
531 which can be invoked via "make test". There are no functional changes
532 to the MD5 routines themselves.
534 *** 96/03/14 Version 1.5.3
536 Fixed addfile method to accept type-glob references for the file-handle
537 (eg \*STDOUT). This is more consistent with other routines and is now the
538 recommended way of passing file-handles. The documentation now gives more
539 examples as to how the routines might be used.
541 *** 96/03/12 Version 1.5.2
543 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
544 support for building on OS/2 (and to work arround a perl -w bug).
546 Remove warning about possible difference between add('foo', 'bar') and
547 add('foobar'). This is not true (it may have been true in the earliest
548 version of the module but is no longer the case).
550 *** 96/03/08 Version 1.5.1
552 Add CHANGES file to make it easier for people to figure out what has
553 been going on. (Meant to do this as part of 1.5)
555 *** 96/03/05 Version 1.5
557 Add hash() and hexhash() methods at the suggestion/request of Gary
558 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
559 of cryptography modules.
561 *** 96/02/27 Version 1.4
563 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
564 Pizzini <kenp@spry.com>!
566 *** 95/11/29 Version 1.3.1
568 Add explanations of current known problems.
570 *** 95/06/02 Version 1.3
572 Fix problems with scope resolution in addfile() reported by
573 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
574 always implicitly in package main while other filehandles aren't.
576 *** 95/05/23 Version 1.2.1
578 [Changes pre 1.2.1 not recorded]
