                -- coordinated with Gisle Aas and J. Duque
                        -- goal is to produce a single SHA module
                -- adheres to OO and functional styles of Digest::
                -- greatly reduces the number of interface functions
                -- old functions still supported
                        -- use Digest::SHA ':legacy'
                        -- will be deprecated in near future
        - rewrote all test scripts to match new interface
                -- very easy to modify all 281 tests
                -- old interface maps cleanly to new one

3.0   Wed Nov 26 05:02:34 MST 2003
        - added functions that conform to Digest:: interface
                -- both functional and OO styles
                        -- byte-oriented data only
                -- continue to support original interface as well
                        -- necessary for bit-oriented data
        - supplied formal test vectors for HMAC-SHA-256
                -- from draft-ietf-ipsec-ciph-sha-256-01.txt
        - included tests for all OO methods

2.4   Sat Nov 22 17:10:22 MST 2003
        - code cleanup
                -- "sha.c" now completely free of #ifdef's
        - modularized all 64-bit (long long) code
        - improved readability of header files
        - simplified logic of "fixdump" utility

2.3   Wed Nov 19 03:54:31 MST 2003
        - minor optimizations and code cleanup
                -- improved maintainability by reducing #ifdef's
                -- sha1 transform code now easier to follow
        - streamlined shadump/shaload file format
                -- eliminated special "HQ" entry
                -- state now held in "H" for all transforms
                -- supplied "fixdump" utility to convert old format
        - SHA-384/512 functions now return NULL for no 64-bit operations
                -- previously they were undefined
                -- 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
