5 Moved all other Digest:: modules out of the Digest-MD5 dist.
9 2000-09-18 Gisle Aas <gisle@ActiveState.com>
13 Avoid pointer cast warning for machines with bigger ints
14 than pointers. Patch by Robin Barker <rmb1@cise.npl.co.uk>.
18 2000-08-19 Gisle Aas <gisle@ActiveState.com>
22 The fallback code introduced in 2.10 did only work for
23 perl-5.6.0. It should now for for perl5.004 and 5.005
24 as well. Patch by Ville Skyttä <ville@office.popsystems.com>.
28 2000-08-18 Gisle Aas <gisle@ActiveState.com>
32 Digest::MD5 will now try to fallback to the pure perl
33 implementation of Digest::Perl::MD5 if bootstrap fails.
35 Added a bit internal paranoia about casting the IV
36 in the Digest::MD5 object to the MD5_CTX* pointer.

52 The addfile() methods could trigger a core dump when passed
53 a filehandle that had failed to open.
57 1999-04-26 Gisle Aas <gisle@aas.no>
61 The Digest::SHA1 module failed on some 64-bit systems, because I
62 assumed there was a correspondence between the U32 size and
63 BYTEORDER. This version use 'unsigned long' as Uwe's original
66 The module should now work better when liked statically with perl,
67 because we now use a safer module-loaded test in Digest.pm.
69 Assume we know the outcome of the alignment test on VMS. Patch by
70 Chuck Lane <lane@duphy4.physics.drexel.edu>
74 1999-03-26 Gisle Aas <gisle@aas.no>
78 Avoid LONG and BYTE types in SHA.xs as they was in conflict
79 with similar definitions in <winnt.h>.
81 Patch by Marko Asplund <aspa@hip.fi> to make the the alignment
82 test program link successfully with sfio-perl.
84 Fixed a typo in MD5.xs that might have affected 64-bit systems.
85 Spotted by Nick Ing-Simmons
89 1999-03-15 Gisle Aas <gisle@aas.no>
93 Included Digest::SHA1 based on Uwe Hollerbach's SHA module.
97 1999-03-05 Gisle Aas <gisle@aas.no>
101 Avoid the -o option when compiling alignment test program
102 for Win32 as suggested by Gurusamy Sarathy.
104 DEC Compiler bug workaround. Contributed by D Roland Walker
105 <walker@ncbi.nlm.nih.gov>
107 Having references to a local variable called "na" was not
108 very safe either. Some older versions of Perl can apparently
109 macroize this into something completely different.
113 1999-02-27 Gisle Aas <gisle@aas.no>
117 Patch from Christopher J. Madsen <chris_madsen@geocities.com> that
118 should help getting the u32align test program to compile with
119 Visual C++ 5 on Windows NT.
121 Got rid of references to PL_na.
125 1999-01-31 Gisle Aas <gisle@aas.no>
129 Added a hints file as workaround for an IRIX compiler bug.
130 Contributed by D Roland Walker <walker@ncbi.nlm.nih.gov>.
132 Note that the rfc2202 test can still fail on some DEC Alpha,
133 because of a compiler bug that affects the perl 'x' operator.
134 The Digest:: modules should work and be safe to install anyway.
138 1998-12-18 Gisle Aas <aas@sn.no>
142 Some casts and tweaks to make picky compilers more happy.
146 1998-11-04 Gisle Aas <aas@sn.no>
150 Taken out Digest::SHA1 as this module will be provided from Uwe
153 Some tweaks to MD2.xs and MD5.xs since "na" disappeared in
158 1998-10-30 Gisle Aas <aas@sn.no>
162 The 1.99_59 release introduced compilation problems for big-endian
163 systems with free U32 alignment. Bug reported, and fix suggested
164 by Paul J. Schinder <schinder@pobox.com>.
168 1998-10-28 Gisle Aas <aas@sn.no>
172 Makefile.PL will run a test program to find out if U32 values can
173 be aligned anywhere. This hopefully cures the core dumps reported
174 on Solaris and other big endian systems. Thanks to Graham Barr for
179 1998-10-28 Gisle Aas <aas@sn.no>
183 Should be very close to a 2.00 release now. Need some success
184 reports from people running on big-endian machines first I think.
186 Added a Digest::MD2 implementation.
188 Wrote Digest.pm documentation. This define the interface that all
189 Digest:: modules should provide.
191 Avoided some code duplication in MD5.xs
193 Fixed typo, that prevented Digest::SHA1::sha1_base64() from working.
197 1998-10-27 Gisle Aas <aas@sn.no>
201 Rewritten most of the MD5 C code to make it real fast (especially
202 on little-endian machines without alignment restrictions for U32).
203 Compared to MD5-1.7 we can process files 4 times as fast and we
204 digest small stuff in memory 7 times faster. I came to these
205 conclusions after these tests (gcc -O2, i586, Linux):
207 First tested calculation of the digest of a 31 MB file, using
208 perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest'
212 Digest::MD5-1.99_57: 5.23s
213 md5sum (GNU textutils): 4.90s
215 As you can see, we do nearly as good as the md5sum program. I
216 think the reason we don't beat md5sum is that perl always insist on
217 loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm,
218 AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs
219 hasher code in a C program I managed to process the file in 4.68s.
221 Then we calculated the digest of the same 6 byte sting, 20000
225 Digest::MD5-1.99_57: 1.68s
227 Digest::MD5 benefit from making this into a plain procedure call
228 instead of a static method call.
231 Other changes in this release are:
235 Internal MD5.xs cleanup.
237 $md5->digest will automatically reset now.
239 Digest::HMAC methods add() and addfile() did not return the
242 Added Digest.pm loading module. I am not sure this is a good idea.
244 Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1
245 module is just a wrapper around SHA.pm. I hope to get the author
246 of SHA.pm to move his module to the Digest:: category.
250 1998-10-25 Gisle Aas <aas@sn.no>
254 Fix memcpy_byteswap() function in MD5.xs. Must be careful with
255 htovl() as it might evaluate its arguments more than once.
259 1998-10-25 Gisle Aas <aas@sn.no>
263 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and
264 Digest::HMAC_MD5. Also provide functional interface. Documentation
267 Included RFC 2202 based test for HMAC-MD5.
271 1998-10-24 Gisle Aas <aas@sn.no>
275 Included HMAC_MD5.pm, contributed by Graham Barr <gbarr@ti.com>.
277 I have a hard time to make up my mind :-) md5_bin() renamed back
278 to md5(). Functions are not exported by default any more.
280 Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian
285 1998-10-23 Gisle Aas <aas@sn.no>
289 Renamed core module as Digest::MD5. Leave a MD5.pm stub for
292 The md5() function renamed as md5_bin().
294 The constructor, Digest::MD5->new, no longer takes any extra
297 Added some new tests.
299 Updated the documentation.
301 $md5->b64digest implemented with same base64 encoder as md5_base64.
305 1998-10-23 Gisle Aas <aas@sn.no>
309 Patch from Graham Barr which make it work for big-endian machines
314 1998-10-22 Gisle Aas <aas@sn.no>
318 The MD5 class is now subclassable.
320 The add() and addfile() methods now return $self.
322 The reset() method is just an alias for new().
324 The constructor (MD5->new) now takes optional arguments which are
325 automatically added. It means that we can now write:
327 MD5->new($data)->hexdigest;
329 New $md5->b64digest method.
331 New functions that are exported on request: md5, md5_hex, md5_base64
335 Barely started to update the documentation.
339 1998-10-22 Gisle Aas <aas@sn.no>
343 Much better performance (more than twice as fast now). Mostly
344 because we use Copy/Zero instead of the original MD5_memcpy and
345 MD5_memset functions.
347 The addfile() and hexdigest() methods are now XS implemented.
349 All RSA functions now included in MD5.xs and made static.
351 Use perl's Copy/Zero.
353 Random cleanup, simplifications and reformatting.
354 Merged things better with the perl configuration.
358 Neil Winton's versions below:
361 *** 96/06/20 Version 1.7
363 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses
364 32-bit quantities and requires a typedef UINT4 to be defined in
365 global.h. Perl configuration data (the value of BYTEORDER) is used to
366 determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg
367 DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type.
368 If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in
369 Makefile.PL will override this.
371 On some machines (at least Cray that I know of) there is no 32-bit
372 integer type. In this case defining TRUNCATE_UINT4 (which is done
373 automatically for a Cray) will ensure that 64-bit values are masked
374 down to 32 bits. I have done my best to test this but without easy
375 access to a true 64-bit machine I can not totally guarantee it (unless
376 anyone wants to lend me a spare Cray :-)
378 There is one remaining limitation for 64-bit enabled processors. The
379 amount of data passed to any single call to the underlying MD5
380 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm
381 sorry if that's a real problem for you ...
383 And finally, a minor complilation warning (unsigned char * used with
384 function having char * prototype) has also been eliminated.
386 *** 96/04/09 Version 1.6
388 Re-generated module framework using h2xs to pick up the latest module
389 conventions for versions etc. You can now say "use MD5 1.6;" and things
390 should work correctly. MD5.pod has been integrated into MD5.pm and
391 CHANGES renamed to Changes. There is a fairly comprehensive test.pl
392 which can be invoked via "make test". There are no functional changes
393 to the MD5 routines themselves.
395 *** 96/03/14 Version 1.5.3
397 Fixed addfile method to accept type-glob references for the file-handle
398 (eg \*STDOUT). This is more consistent with other routines and is now the
399 recommended way of passing file-handles. The documentation now gives more
400 examples as to how the routines might be used.
402 *** 96/03/12 Version 1.5.2
404 Minor fixes from Christopher J Madsen <madsen@computek.net> to provide
405 support for building on OS/2 (and to work arround a perl -w bug).
407 Remove warning about possible difference between add('foo', 'bar') and
408 add('foobar'). This is not true (it may have been true in the earliest
409 version of the module but is no longer the case).
411 *** 96/03/08 Version 1.5.1
413 Add CHANGES file to make it easier for people to figure out what has
414 been going on. (Meant to do this as part of 1.5)
416 *** 96/03/05 Version 1.5
418 Add hash() and hexhash() methods at the suggestion/request of Gary
419 Howland <gary@kampai.euronet.nl> before inclusion in a wider library
420 of cryptography modules.
422 *** 96/02/27 Version 1.4
424 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken
425 Pizzini <kenp@spry.com>!
427 *** 95/11/29 Version 1.3.1
429 Add explanations of current known problems.
431 *** 95/06/02 Version 1.3
433 Fix problems with scope resolution in addfile() reported by
434 Jean-Claude Giese <Jean-Claude.Giese@loria.fr>. Basically ARGV is
435 always implicitly in package main while other filehandles aren't.
437 *** 95/05/23 Version 1.2.1
439 [Changes pre 1.2.1 not recorded]
