Revision history for Perl module Digest::SHA::PurePerl.

5.48 Mon Jan 4 16:32:52 MST 2010

• fixed "shasum -a0" option (ref. rt.cpan.org #53319)

  -- incorrectly accepted 0 as a valid algorithm

  -- thanks to Zefram for patch

• updated URL for NIST test vectors

  -- ref. files t/nistbit.t, t/nistbyte.t

  -- thanks to Leon Brocard for patch

5.47 Wed Apr 30 04:00:54 MST 2008

• moved .pm file to appropriate lib directory
• minor addition to META.yml

5.46 Wed Apr 9 05:04:00 MST 2008

• modified _Addfile to recognize leading and trailing

  whitespace in filenames (ref. rt.cpan.org #34690)

• previous version commandeered the warnings flag ($^W)

  -- this version disables warnings only when

  compiling 64-bit constants

5.45 Tue Jun 26 02:36:00 MST 2007

• extended portability to earlier Perls

  -- works on Perl 5.003 and later -- thanks to Jim Doble for testing on legacy platforms

• updated META.yml to conform to current META spec (1.3)
• minor documentation fixes

5.44 Sat Oct 14 00:42:44 MST 2006

• removed SIGNATURE file from distribution

  -- spurious errors from CPANPLUS can break build

5.43 Sat Aug 5 02:36:18 MST 2006

• undid Perl Best Practice of favoring 3-argument "open"

  -- 3-arg version uses different semantics for "-"

  causing bugs in addfile/shadump/shaload/shasum

5.42 Mon Jul 24 04:04:40 MST 2006

• minor code changes suggested by Perl::Critic

  -- e.g. no bareword filehandles, no 2-argument open's

• updated public key (ref. B538C51C)

  -- previous one (0AF563FE) expired July 2, 2006

• added documentation to warn that Base64 digests are NOT padded

  -- padding must be done by user if interoperability

  with other software is required

5.41 Sat Jun 3 01:50:46 MST 2006

• corrected addfile

  -- process $file argument as a filehandle unless passed

  as a SCALAR (which indicates a file name)

5.40 Fri Jun 2 04:00:30 MST 2006

• modified addfile to accept indirect filehandles

  -- ref. rt.cpan.org #19627 and #19641

5.39 Sun May 28 03:22:24 MST 2006

• modified shasum to warn rather than die for file errors

  -- to follow conventions of GNU sha1sum/md5sum

5.38 Thu May 25 02:02:02 MST 2006

• added new capabilities to the "addfile" method

  -- now able to accept file names as well as handles -- includes mode for portable digest calculation

  -- thanks to Adam Kennedy for emails and ideas

  ref. File::LocalizeNewlines

• used expanded addfile interface to simplify shasum (sumfile)

  -- regex a tad less general than 5.37, but handles all

  known newline variants in UNIX/Windows/MacOS

• enhanced WARNING messages from shasum checkfile processing

  -- to mimic behavior of md5sum

5.37 Mon May 8 04:30:09 MST 2006

• modified shasum to avoid file slurping (ref. sub sumfile)
• improved error handling of checksum files in shasum

  -- to better mimic the behavior of md5sum

• refined line-break regex in shasum (ref. sub sumfile)

  -- catches multiple CR's preceding LF

  thanks to Gisle Aas for suggested patch

5.36 Mon May 8 01:38:36 MST 2006

• fixed the "portable" option in shasum

  -- normalize line-breaks in text files only

5.35 Thu May 4 16:54:42 MST 2006

• added "portable" option to shasum

  -- to make digests match across Windows/Unix/MacOS

• enabled bundling of shasum command line options

  -- to mimic behavior of md5sum

• removed \r's from text files in t/nist directory

  -- resolves SIGNATURE clashes (rt.cpan.org #18983)

• specified minimum Perl version for module and Makefile.PL

  -- closes rt.cpan.org #18984

5.34 Thu Feb 2 18:55:40 MST 2006

• removed Unix-style pathnames in test scripts

  -- causing problems on OpenVMS -- thanks to Steve Peters for patch

• added PERL_CORE check to test scripts

  -- allows module to be built into Perl distribution

5.32 Fri Dec 2 02:32:20 MST 2005

• added POD section to shasum script

  -- thanks to Gunnar Wolf for patch

• inserted code in test scripts for POD checking

  -- to recover gracefully if Test::More isn't installed

5.31 Mon Sep 5 00:52:42 MST 2005

• added standard tests for pod and pod-coverage checking
• inserted subtest to check for failure when using

  unrecognized SHA algorithm

• consolidated code for SHA and HMAC-SHA functions

  -- removed 190 lines by building functions at runtime

• harmonized _sharewind and _shaopen subs with C versions

  -- other minor code cleanups

5.30 Sat Aug 20 16:46:08 MST 2005

• updated docs with recent NIST statement on SHA-1

  -- advises use of larger and stronger hash functions

  (i.e. SHA-224/256/384/512) for new developments

5.29 Sun Aug 14 04:48:34 MST 2005

• updated docs with cautionary note about SHA-1

5.26 Thu Oct 7 14:52:00 MST 2004

• streamlined distribution

  -- reduced NIST vector tests from 200 to 20

  -- former number was overkill -- distro now downloads and builds more quickly

• made additional tweaks to t/8-shasum.t for portability
• cleaned up test scripts

5.25 Sun Sep 12 18:48:00 MST 2004

0.06 Tue Aug 3 02:12:40 MST 2004

• improved performance of SHA-384/512

  -- using inline eval'ed code instead of subroutines -- 5.7 x faster than Version 0.05

0.04 Fri Jul 2 01:10:48 MST 2004
