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

0.05  Sun Aug  1 03:56:54 MST 2004
	- fixed HMAC-SHA-384/512 bug
		-- code was using hardwired blocksize of SHA-1/256
	- added test cases to check HMAC-SHA-384/512 behavior
		-- thanks to Adam Woodbury for vectors and script mods
	- corrected misspelling in docs
		-- apologies to Gisle Aas

0.04  Fri Jul  2 01:10:48 MST 2004
	- added support for SHA-384/512
		-- module now offers full functionality of Digest::SHA
		-- however, use of SHA-384/512 requires 64-bit integers
	- included a SIGNATURE file
		-- for stronger authentication of module contents
			-- ref. Module::Signature on CPAN

0.03  Fri Jun 25 00:06:54 MST 2004
	- portability fix
		-- dump files caused warnings on 64-bit platforms
		-- enhanced "dump-load.t" to check correct behavior
	- performance tweak for 64-bit machines
		-- eliminated upper-32-bit masking on left shifts
		-- instead, need to mask only in _digcpy and _shadump

0.02  Tue Jun 22 04:24:00 MST 2004
	- Increased speed of SHA transforms
		-- using optimization ideas from Digest::SHA package
		-- SHA-1       ~  20% faster
		-- SHA-224/256 ~ 120% faster

0.01  Thu Jun 17 00:04:00 MST 2004
	- Initial version, derived from Digest::SHA 5.01
		-- hand-translation from C to Perl
