-- no longer necessary to use eval's to test for presence
2.2 Sun Nov 16 01:54:00 MST 2003
- optimized the performance of the SHA-1 transform
-- around 20-30% faster than previous version
-- achieved by loop unrolling and assignment consolidation
- enhanced shaload/shadump to allow interaction with stdin/stdout
-- "$filename" argument now optional
2.1 Sun Nov 9 03:28:04 MST 2003
- simplified data input routines
-- length argument now optional for byte data
(special thanks to Jeffrey Friedl for this idea)
-- interface still compatible with earlier versions
-- changes will not affect existing client code
- streamlined underlying C code for easier maintenance
- provided additional tests for persistent data
2.0 Sat Nov 1 03:55:36 MST 2003
- added functions for HMAC-SHA-1/256/384/512 (FIPS PUB 198)
- shadump/shaload files now compatible between 32/64-bit machines
1.01 Sat Oct 25 02:44:55 MST 2003
- package now downloads and installs much faster
- reduced distribution size by 80%
-- pruned extensive NIST vectors to a useful subset
-- still possible to test all vectors if desired
--- see "t/nist/COPYRIGHT" file for details
- added routines to provide persistent storage of SHA states
-- shadump() and shaload()
- reduced runtime of large bitstring tests (gillogly-hard)
-- illustrates usefulness of shadump()/shaload()
1.0 Sat Oct 18 17:35:07 MST 2003
- documentation fixes
- code cleanup: no more compiler warnings from gcc -Wall
- added code to allow reading of intermediate digest state
-- shahex() prior to shafinish() returns current state
0.9 Thu Oct 9 20:43:54 MST 2003
- version updated to reflect portability check and passing
of all tests (1401)
0.01 Wed Oct 8 22:28:05 2003
- original version; created by h2xs 1.22 with options
-x -A -n Digest::SHA sha.h
