2005-11-30 Gisle Aas Release 2.36 Fix documentation typo. 2005-11-26 Gisle Aas Release 2.35 Forgot to incorporate fixes already applied to bleadperl :-( - doc typo - consting - unused my_na - USE_HEAP_INSTEAD_OF_STACK for Symbian 2005-11-26 Gisle Aas Release 2.34 Document that it is now easy to generate different messages that produce the same MD5 digest. Use XSLoader; perl-5.6 is now required. Tweaks to the processing of $? after running the test program. 2003-12-07 Gisle Aas Release 2.33 Enable explicit context passing for slight performance improvement in threaded perls. Tweaks to the Makefile.PL so that it is suitable both for core and CPAN use. 2003-12-05 Gisle Aas Release 2.32 Don't run u32align test program on HP-UX 10.20 as it will hang. Patch by H.Merijn Brand . Fixed documentation typo. 2003-11-28 Gisle Aas Release 2.31 Inherit add_bits() from Digest::base if available. 2003-10-09 Gisle Aas Release 2.30 Some tweaks to make the module build on perl-5.004 and perl-5.005 again. 2003-10-06 Gisle Aas Release 2.29 Another try. Forgot to update the test checksums. 2003-10-06 Gisle Aas Release 2.28 Fix minor documentation typo. 2003-08-04 Gisle Aas Release 2.27 Avoid having to figure how to compile alignment test program on MS-Windows by just assume free alignment as for i386. Source builds on Windows was apparently broken. 2003-07-21 Gisle Aas Release 2.26 Don't assume PerlIO_read() works like fread() even though it was documented like that for perl 5.6. It returns negative on read failure. Kill test #3 in t/badfile.t. I don't know a reliable way to test read failures on a file handle. Seems better not to test than to make many worry. 2003-07-04 Gisle Aas Release 2.25 The $md5->addfile method now croaks if it discovers errors on the handle after reading from it. This should make it more difficult to end up with the wrong digest just because you are to lazy to check the error status on your file handles after reading from them. Improved documentation. Sync up with bleadperl; even safer patchlevel include. 2003-03-09 Gisle Aas Release 2.24 Don't let the $^W test get confused by lexical warnings. Sync up with bleadperl; safer patchlevel include. 2003-01-18 Gisle Aas Release 2.23 Override INSTALLDIRS for 5.8 as suggested by Guido Ostkamp . 2003-01-04 Gisle Aas Release 2.22. Added clone method. Contributed by Holger Smolinski 2002-12-27 Gisle Aas Release 2.21 Minor tweaks sync up with bleadperl: - VMS optimizer tweaks to the Makefile.PL - MacOS support - Added alignment test Added example to the MD5 POD that shows how to calculate the digest of Unicode strings. 2002-05-05 Gisle Aas Release 2.20 More synchronization with tweaks Jarkko have done to the bleadperl test suite. This time various EBCDIC hacks. Outside PERL_CORE the md5-aaa.t test loaded the wrong version of the module (and would fail if no previous Digest::MD5 was installed). Patch by Mike Stok 2002-05-01 Gisle Aas Release 2.19 One more test suite update from Jarkko to sync it even better with bleadperl. 2002-05-01 Gisle Aas Release 2.18 Changes #12954 and #16173 from bleadperl. Documentation typo fix and some signed/unsigned mismatches that Microsoft's C compiler complained about. The EBCDIC-aware md5-aaa.t from bleadperl. 2002-04-25 Gisle Aas Release 2.17 The SvPVbyte in perl-5.6.1 is buggy. Use the one from 5.7.3 instead. Give warning if the function interface is used as instance methods: $md5->md5_hex(). 2001-09-07 Gisle Aas Release 2.16 Sync up with the bleadperl version: - use SvPVbyte() if available - fixes to make the code 'gcc -Wall'-clean 2001-08-27 Gisle Aas Release 2.15 Avoid exit() in Makefile.PL and bleadperl redefinition of printf in the alignment test program. Patch by Doug MacEachern . 2001-07-18 Gisle Aas Release 2.14 Try to warn if the functional interface is used as methods, i.e. Digest::MD5->md5_hex("foo") will make noise if -w is enabled. Document the missing padding for the base64 digests. If both XS bootstrap and locating Digest::Perl::MD5 fails re-raise the original XS bootstrap exception. 2001-03-13 Gisle Aas Release 2.13 Moved all other Digest:: modules out of the Digest-MD5 dist. 2000-09-18 Gisle Aas Release 2.12 Avoid pointer cast warning for machines with bigger ints than pointers. Patch by Robin Barker . 2000-08-19 Gisle Aas Release 2.11 The fallback code introduced in 2.10 did only work for perl-5.6.0. It should now for for perl5.004 and 5.005 as well. Patch by Ville Skyttä . 2000-08-18 Gisle Aas Release 2.10 Digest::MD5 will now try to fallback to the pure perl implementation of Digest::Perl::MD5 if bootstrap fails. Added a bit internal paranoia about casting the IV in the Digest::MD5 object to the MD5_CTX* pointer. 1999-08-06 Gisle Aas Release 2.09 Documentation update. 1999-07-28 Gisle Aas Release 2.08 The addfile() methods could trigger a core dump when passed a filehandle that had failed to open. 1999-04-26 Gisle Aas Release 2.07 The Digest::SHA1 module failed on some 64-bit systems, because I assumed there was a correspondence between the U32 size and BYTEORDER. This version use 'unsigned long' as Uwe's original SHA module did. The module should now work better when liked statically with perl, because we now use a safer module-loaded test in Digest.pm. Assume we know the outcome of the alignment test on VMS. Patch by Chuck Lane 1999-03-26 Gisle Aas Release 2.06 Avoid LONG and BYTE types in SHA.xs as they was in conflict with similar definitions in . Patch by Marko Asplund to make the the alignment test program link successfully with sfio-perl. Fixed a typo in MD5.xs that might have affected 64-bit systems. Spotted by Nick Ing-Simmons 1999-03-15 Gisle Aas Release 2.05 Included Digest::SHA1 based on Uwe Hollerbach's SHA module. 1999-03-05 Gisle Aas Release 2.04 Avoid the -o option when compiling alignment test program for Win32 as suggested by Gurusamy Sarathy. DEC Compiler bug workaround. Contributed by D Roland Walker Having references to a local variable called "na" was not very safe either. Some older versions of Perl can apparently macroize this into something completely different. 1999-02-27 Gisle Aas Release 2.03 Patch from Christopher J. Madsen that should help getting the u32align test program to compile with Visual C++ 5 on Windows NT. Got rid of references to PL_na. 1999-01-31 Gisle Aas Release 2.02 Added a hints file as workaround for an IRIX compiler bug. Contributed by D Roland Walker . Note that the rfc2202 test can still fail on some DEC Alpha, because of a compiler bug that affects the perl 'x' operator. The Digest:: modules should work and be safe to install anyway. 1998-12-18 Gisle Aas Release 2.01 Some casts and tweaks to make picky compilers more happy. 1998-11-04 Gisle Aas Release 2.00. Taken out Digest::SHA1 as this module will be provided from Uwe Hollerbach later. Some tweaks to MD2.xs and MD5.xs since "na" disappeared in perl5.005_53 1998-10-30 Gisle Aas Release 1.99_60 The 1.99_59 release introduced compilation problems for big-endian systems with free U32 alignment. Bug reported, and fix suggested by Paul J. Schinder . 1998-10-28 Gisle Aas Release 1.99_59 Makefile.PL will run a test program to find out if U32 values can be aligned anywhere. This hopefully cures the core dumps reported on Solaris and other big endian systems. Thanks to Graham Barr for debugging this. 1998-10-28 Gisle Aas Release 1.99_58 Should be very close to a 2.00 release now. Need some success reports from people running on big-endian machines first I think. Added a Digest::MD2 implementation. Wrote Digest.pm documentation. This define the interface that all Digest:: modules should provide. Avoided some code duplication in MD5.xs Fixed typo, that prevented Digest::SHA1::sha1_base64() from working. 1998-10-27 Gisle Aas Release 1.99_57 Rewritten most of the MD5 C code to make it real fast (especially on little-endian machines without alignment restrictions for U32). Compared to MD5-1.7 we can process files 4 times as fast and we digest small stuff in memory 7 times faster. I came to these conclusions after these tests (gcc -O2, i586, Linux): First tested calculation of the digest of a 31 MB file, using perl -le 'print Digest::MD5->new->addfile(*STDIN)->hexdigest' and similar stuff: MD5-1.7: 21.06s Digest::MD5-1.99_57: 5.23s md5sum (GNU textutils): 4.90s As you can see, we do nearly as good as the md5sum program. I think the reason we don't beat md5sum is that perl always insist on loading extra modules like Config.pm, Carp.pm, strict.pm, vars.pm, AutoLoader.pm and DynaLoader.pm. When I simply wrapped the MD5.xs hasher code in a C program I managed to process the file in 4.68s. Then we calculated the digest of the same 6 byte sting, 20000 times: MD5-1.7: 11.81s Digest::MD5-1.99_57: 1.68s Digest::MD5 benefit from making this into a plain procedure call instead of a static method call. Other changes in this release are: Documentation update Internal MD5.xs cleanup. $md5->digest will automatically reset now. Digest::HMAC methods add() and addfile() did not return the correct object. Added Digest.pm loading module. I am not sure this is a good idea. Added Digest::SHA1 and Digest::HMAC_SHA1 module. The Digest::SHA1 module is just a wrapper around SHA.pm. I hope to get the author of SHA.pm to move his module to the Digest:: category. 1998-10-25 Gisle Aas Release 1.99_56 Fix memcpy_byteswap() function in MD5.xs. Must be careful with htovl() as it might evaluate its arguments more than once. 1998-10-25 Gisle Aas Release 1.99_55 Grahams HMAC_MD5.pm splitted into two modules. Digest::HMAC and Digest::HMAC_MD5. Also provide functional interface. Documentation is still lacking. Included RFC 2202 based test for HMAC-MD5. 1998-10-24 Gisle Aas Release 1.99_54 Included HMAC_MD5.pm, contributed by Graham Barr . I have a hard time to make up my mind :-) md5_bin() renamed back to md5(). Functions are not exported by default any more. Try to Encode/Decode with memcpy_byteswap for 32-bit big-endian machines. 1998-10-23 Gisle Aas Release 1.99_53 Renamed core module as Digest::MD5. Leave a MD5.pm stub for legacy code. The md5() function renamed as md5_bin(). The constructor, Digest::MD5->new, no longer takes any extra arguments. Added some new tests. Updated the documentation. $md5->b64digest implemented with same base64 encoder as md5_base64. 1998-10-23 Gisle Aas Release 1.99_52 Patch from Graham Barr which make it work for big-endian machines again. 1998-10-22 Gisle Aas Release 1.99_51 The MD5 class is now subclassable. The add() and addfile() methods now return $self. The reset() method is just an alias for new(). The constructor (MD5->new) now takes optional arguments which are automatically added. It means that we can now write: MD5->new($data)->hexdigest; New $md5->b64digest method. New functions that are exported on request: md5, md5_hex, md5_base64 Included RFC 1321 Barely started to update the documentation. 1998-10-22 Gisle Aas Release 1.99_50 Much better performance (more than twice as fast now). Mostly because we use Copy/Zero instead of the original MD5_memcpy and MD5_memset functions. The addfile() and hexdigest() methods are now XS implemented. All RSA functions now included in MD5.xs and made static. Use perl's Copy/Zero. Random cleanup, simplifications and reformatting. Merged things better with the perl configuration. Neil Winton's versions below: *** 96/06/20 Version 1.7 MD5 is now completely 64-bit clean (I hope). The basic MD5 code uses 32-bit quantities and requires a typedef UINT4 to be defined in global.h. Perl configuration data (the value of BYTEORDER) is used to determine if unsigned longs have 4 or 8 bytes. On 64-bit platforms (eg DEC Alpha) then it assumes that "unsigned int" will be a 32-bit type. If this is incorrect then adding -DUINT4_IS_LONG to the DEFINES line in Makefile.PL will override this. On some machines (at least Cray that I know of) there is no 32-bit integer type. In this case defining TRUNCATE_UINT4 (which is done automatically for a Cray) will ensure that 64-bit values are masked down to 32 bits. I have done my best to test this but without easy access to a true 64-bit machine I can not totally guarantee it (unless anyone wants to lend me a spare Cray :-) There is one remaining limitation for 64-bit enabled processors. The amount of data passed to any single call to the underlying MD5 routines is limited to (2^32 - 1) bytes -- that's 4 gigabytes. I'm sorry if that's a real problem for you ... And finally, a minor compilation warning (unsigned char * used with function having char * prototype) has also been eliminated. *** 96/04/09 Version 1.6 Re-generated module framework using h2xs to pick up the latest module conventions for versions etc. You can now say "use MD5 1.6;" and things should work correctly. MD5.pod has been integrated into MD5.pm and CHANGES renamed to Changes. There is a fairly comprehensive test.pl which can be invoked via "make test". There are no functional changes to the MD5 routines themselves. *** 96/03/14 Version 1.5.3 Fixed addfile method to accept type-glob references for the file-handle (eg \*STDOUT). This is more consistent with other routines and is now the recommended way of passing file-handles. The documentation now gives more examples as to how the routines might be used. *** 96/03/12 Version 1.5.2 Minor fixes from Christopher J Madsen to provide support for building on OS/2 (and to work around a perl -w bug). Remove warning about possible difference between add('foo', 'bar') and add('foobar'). This is not true (it may have been true in the earliest version of the module but is no longer the case). *** 96/03/08 Version 1.5.1 Add CHANGES file to make it easier for people to figure out what has been going on. (Meant to do this as part of 1.5) *** 96/03/05 Version 1.5 Add hash() and hexhash() methods at the suggestion/request of Gary Howland before inclusion in a wider library of cryptography modules. *** 96/02/27 Version 1.4 Finally fixed the pesky Solaris dynamic loading bug. All kudos to Ken Pizzini ! *** 95/11/29 Version 1.3.1 Add explanations of current known problems. *** 95/06/02 Version 1.3 Fix problems with scope resolution in addfile() reported by Jean-Claude Giese . Basically ARGV is always implicitly in package main while other filehandles aren't. *** 95/05/23 Version 1.2.1 [Changes pre 1.2.1 not recorded]
