Revision history for Perl extension Digest::SHA3.
1.05 Mon 08 Aug 2022 11:30:32 AM MST
- corrected addfile to report error when stdin is a directory
-- ref. rt.cpan.org #143899
-- thanks to Gregor Herrmann for pointing this out
1.04 Fri Apr 20 16:25:30 MST 2018
- silenced compiler warnings from VS2017
-- ref. rt.cpan.org #124477
-- thanks to Sergey Aleynikov for diagnostics
- modified addfile to return error when given a directory name
-- makes behavior consistent with GNU coreutils shaXsum
-- thanks to Scott Baker for pointing this out
1.03 Mon Dec 25 00:08:10 MST 2017
- added "--ignore-missing" and "--strict" options to sha3sum
-- consistent with GNU coreutils
-- ref. rt.cpan.org #123897
1.02 Fri Dec 8 22:44:46 MST 2017
- added "tag" option (BSD-style checksums) to sha3sum
-- consistent with GNU sha1sum, sha224sum, etc.
-- thanks to Christopher Tubbs for suggestion
- modified SHA3.pm to use XSLoader
-- falls back to DynaLoader if necessary
1.01 Sun Oct 22 16:04:22 MST 2017
- added optional $lsb argument for add_bits() method
-- many public vectors in least-significant-bit format
-- using $lsb flag results in simpler test code
- further minor optimizations in add_bits() and tests
1.00 Sat Oct 14 18:08:10 MST 2017
- promoted to major release version 1.0
-- module stable enough not to be considered draft
- fixed alignment issue in BITS mode of addfile
-- surfaced only for large non-aligned inputs
0.27 Wed Oct 4 00:40:04 MST 2017
- removed "portable" mode from sha3sum and addfile
-- rarely used, mostly in outdated systems
-- potentially confusing features (e.g. \r\r\n -> \n)
-- Universal Newlines mode (-U) a much cleaner approach
-- mimics Universal Newlines in Python
- sha3sum now depends explicitly on Digest::SHA3
-- eliminates runtime loading of modules
-- no future plans to write Digest::SHA3::PurePerl
0.26 Wed Sep 6 02:23:08 MST 2017
- added 'quiet' option to sha3sum
-- thanks to Chris David for suggestion and initial patch
-- ref. rt.cpan.org #122750
- expanded sha3sum --help message
-- to explain use of escaped FILE names
0.25 Wed Jul 27 20:04:40 MST 2016
- prevented sha3sum from possibly running malicious code
-- remove '.' from @INC before module loading
-- ref. rt.cpan.org #116513
- namespace cleanup (ref. rt.cpan.org #105371 and #105372)
- minor code and documentation tweaks
0.24 Sat Jan 10 00:45:34 MST 2015
- simplified shabits() routine (bitwise input buffering)
-- slightly less efficient but easier to understand
- minor documentation tweaks and additions
0.23 Sun Jan 4 05:36:30 MST 2015
- updated to reflect Draft FIPS 202
-- append domain separation bits to message
-- implement SHAKE128 and SHAKE256 Extendable-Output
Functions (XOFs)
0.22 Sun Jun 1 00:15:46 MST 2014
- fixed reserved-word clash when compiling with C++
-- use 'classname' instead of 'class'
-- ref. SHA3.xs (rt.cpan.org #96090)
0.21 Fri May 16 10:21:46 MST 2014
- restored original 'addfile' for use on opened file handles
-- allows callbacks in place of actual files
-- ref. IO::Callback (rt.cpan.org #95643)
- re-established inheritance from Digest::base
-- to pick up future Digest enhancements automatically
- cleaned up documentation
0.20 Wed May 7 07:57:10 MST 2014
- consolidated all dynamic memory allocation into XSUBs
-- streamlines referencing of SHA3 objects
-- simplifies DESTROYing of objects
- enhanced Makefile.PL to allow 'use warnings'
-- automatically reverts to $^W for early Perls
- scrubbed C and Perl code to remove all compiler warnings
0.12 Sat Apr 19 05:14:50 MST 2014
- added universal newlines mode ("U") to addfile and sha3sum
-- based on Python Universal Newlines concept
-- newlines identical across MacOS, DOS, and UNIX
-- will deprecate portable mode ("p") in future
-- "U" mode is cleaner and more efficient
- enhanced performance
-- reduced number of dynamic memory allocations
-- sped up addfile method with use of C code
-- ref. SHA3.xs (_addfilebin and _addfileuniv)
- changed text file test (-T) to act on filehandles
-- improves consistency when reading from STDIN
-- still must act on filenames for early Perls (< 5.6)
- sealed memory leak in SHA3.xs
-- arose only with SvPVbyte exceptions during eval
- patched inheritence bug (ref: rt.cpan.org #94830)
-- use sv_isobject/sv_derived_from instead of sv_isa
- added 'allocated' flag to SHA3 structure (ref. src/sha3.h)
-- to guard against Perl double frees
0.11 Mon Feb 17 16:42:04 MST 2014
- tightened code in SHA3.xs
-- added sv_isa checks when invoking methods
0.10 Thu Jan 30 08:24:30 MST 2014
- improved the performance of hexadecimal output functions
-- ref. 'shahex' in src/sha3.c
-- thanks to Thomas Drugeon for ideas and test script
0.09 Sun Jan 5 19:08:32 MST 2014
- added a 'squeeze' method for SHA3-0 objects
-- to construct SHA3-0 digests of any desired length
0.08 Wed Jun 26 04:32:06 MST 2013
- workaround for repeated calls to shaclose
-- ref. Bug #86295 (posted at Digest::SHA)
-- need to explicitly reset internal pointer to NULL
ref. shaclose() in SHA3.xs
- corrected typos in sha3sum script
-- ref. Bug #85430 (posted at Digest::SHA)
0.07 Sat Mar 9 17:36:14 MST 2013
- untweaked Makefile.PL to remove dependencies of SHA3.c
-- dependencies were breaking builds on VMS
-- retaining dependencies provides too little benefit
for cost of portable workaround
0.06 Mon Mar 4 08:12:04 MST 2013
- removed code for standalone C operation (no longer used)
-- eliminates need for external symbols
-- reduces size of object files
-- thanks to Marc Lehmann for suggestions
- tweaked Makefile.PL to show dependencies of SHA3.c
0.05 Thu Jan 24 04:54:14 MST 2013
- accommodated Unicode string input
-- by using SvPVbyte instead of SvPV in SHA3.xs
-- provided workaround for Perl 5.6
-- added new test script t/unicode.t
- provided documentation to describe Unicode handling
- obtained slight speedup on Intel/gcc
-- by setting -O1 and -fomit-frame-pointer
- adopted (from Digest::SHA) workaround for DEC compiler bug
0.04 Sun Nov 11 19:20:06 MST 2012
- enhanced performance
-- typically 10-15% faster than 0.03
-- code is still easy to read and modify
- filled in a few documentation omissions
0.03 Mon Oct 29 04:01:06 MST 2012
- attained a 2.5x performance increase through loop unrolling
-- code is still easy to follow
-- clearly traceable to Keccak pseudo code
0.02 Thu Oct 25 19:18:58 MST 2012
- original version: adapted from Digest::SHA version 5.72
