71 Don't assume PerlIO_read() works like fread() even though
72 it was documented like that for perl 5.6. It returns negative
75 Kill test #3 in t/badfile.t. I don't know a reliable way
76 to test read failures on a file handle. Seems better not to
77 test than to make many worry.
81 2003-07-04 Gisle Aas <gisle@ActiveState.com>
85 The $md5->addfile method now croaks if it discovers
86 errors on the handle after reading from it. This should
87 make it more difficult to end up with the wrong digest
88 just because you are to lazy to check the error status
89 on your file handles after reading from them.
91 Improved documentation.

143 More synchronization with tweaks Jarkko have done to the

393 on Solaris and other big endian systems. Thanks to Graham Barr for
398 1998-10-28 Gisle Aas <aas@sn.no>
402 Should be very close to a 2.00 release now. Need some success
403 reports from people running on big-endian machines first I think.
405 Added a Digest::MD2 implementation.
407 Wrote Digest.pm documentation. This define the interface that all
408 Digest:: modules should provide.
410 Avoided some code duplication in MD5.xs
412 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
416 1998-10-27 Gisle Aas <aas@sn.no>
420 Rewritten most of the MD5 C code to make it real fast (especially
421 on little-endian machines without alignment restrictions for U32).
422 Compared to MD5-1.7 we can process files 4 times as fast and we
423 digest small stuff in memory 7 times faster. I came to these
424 conclusions after these tests (gcc -O2, i586, Linux):
426 First tested calculation of the digest of a 31 MB file, using
427 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
431 Digest::MD5-1.99_57: 5.23s
432 md5sum (GNU textutils): 4.90s
434 As you can see, we do nearly as good as the md5sum program. I
435 think the reason we don't beat md5sum is that perl always insist on
436 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
437 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
438 hasher code in a C program I managed to process the file in 4.68s.
440 Then we calculated the digest of the same 6 byte sting, 20000
444 Digest::MD5-1.99_57: 1.68s
446 Digest::MD5 benefit from making this into a plain procedure call
447 instead of a static method call.
450 Other changes in this release are:
454 Internal MD5.xs cleanup.
456 $md5->digest will automatically reset now.
458 Digest::HMAC methods add() and addfile() did not return the
461 Added Digest.pm loading module. I am not sure this is a good idea.
463 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
464 module is just a wrapper around SHA.pm. I hope to get the author
465 of SHA.pm to move his module to the Digest:: category.
469 1998-10-25 Gisle Aas <aas@sn.no>
473 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
474 htovl() as it might evaluate its arguments more than once.
478 1998-10-25 Gisle Aas <aas@sn.no>
482 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
483 Digest::HMAC_MD5. Also provide functional interface. Documentation
486 Included RFC 2202 based test for HMAC-MD5.
490 1998-10-24 Gisle Aas <aas@sn.no>
494 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
496 I have a hard time to make up my mind :-) md5_bin() renamed back

516 Added some new tests.
518 Updated the documentation.
520 $md5->b64digest implemented with same base64 encoder as md5_base64.

528 Patch from Graham Barr which make it work for big-endian machines
533 1998-10-22 Gisle Aas <aas@sn.no>
537 The MD5 class is now subclassable.
539 The add() and addfile() methods now return $self.
541 The reset() method is just an alias for new().
543 The constructor (MD5->new) now takes optional arguments which are
544 automatically added. It means that we can now write:
546 MD5->new($data)->hexdigest;
548 New $md5->b64digest method.
550 New functions that are exported on request: md5, md5_hex, md5_base64
554 Barely started to update the documentation.
558 1998-10-22 Gisle Aas <aas@sn.no>
562 Much better performance (more than twice as fast now). Mostly
563 because we use Copy/Zero instead of the original MD5_memcpy and
564 MD5_memset functions.
566 The addfile() and hexdigest() methods are now XS implemented.
568 All RSA functions now included in MD5.xs and made static.
570 Use perl's Copy/Zero.
572 Random cleanup, simplifications and reformatting.
573 Merged things better with the perl configuration.
577 Neil Winton's versions below:
580 *** 96/06/20 Version 1.7
582 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
583 32-bit quantities and requires a typedef UINT4 to be defined in
584 global.h. Perl configuration data (the value of BYTEORDER) is used to
585 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
586 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
587 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
588 Makefile.PL will override this.
590 On some machines (at least Cray that I know of) there is no 32-bit
591 integer type. In this case defining TRUNCATE_UINT4 (which is done
592 automatically for a Cray) will ensure that 64-bit values are masked
593 down to 32 bits. I have done my best to test this but without easy
594 access to a true 64-bit machine I can not totally guarantee it (unless
595 anyone wants to lend me a spare Cray :-)
597 There is one remaining limitation for 64-bit enabled processors. The
598 amount of data passed to any single call to the underlying MD5
599 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
600 sorry if that's a real problem for you ...
602 And finally, a minor compilation warning (unsigned char * used with
603 function having char * prototype) has also been eliminated.
605 *** 96/04/09 Version 1.6
607 Re-generated module framework using h2xs to pick up the latest module
608 conventions for versions etc. You can now say "use MD5 1.6;" and things
609 should work correctly. MD5.pod has been integrated into MD5.pm and
610 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
611 which can be invoked via "make test". There are no functional changes
612 to the MD5 routines themselves.
614 *** 96/03/14 Version 1.5.3
616 Fixed addfile method to accept type-glob references for the file-handle
617 (eg \*STDOUT). This is more consistent with other routines and is now the
618 recommended way of passing file-handles. The documentation now gives more
619 examples as to how the routines might be used.
621 *** 96/03/12 Version 1.5.2
623 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
624 support for building on OS/2 (and to work around a perl -w bug).
626 Remove warning about possible difference between add('foo', 'bar') and
627 add('foobar'). This is not true (it may have been true in the earliest
628 version of the module but is no longer the case).
630 *** 96/03/08 Version 1.5.1
632 Add CHANGES file to make it easier for people to figure out what has
633 been going on. (Meant to do this as part of 1.5)
635 *** 96/03/05 Version 1.5
637 Add hash() and hexhash() methods at the suggestion/request of Gary
638 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
639 of cryptography modules.
641 *** 96/02/27 Version 1.4
643 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
644 Pizzini <kenp@spry.com>!
646 *** 95/11/29 Version 1.3.1
648 Add explanations of current known problems.
650 *** 95/06/02 Version 1.3
652 Fix problems with scope resolution in addfile() reported by
653 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
654 always implicitly in package main while other filehandles aren't.
656 *** 95/05/23 Version 1.2.1
658 [Changes pre 1.2.1 not recorded]
