This package contains Perl extension interfaces for the following message digest algorithms: - RSA Data Security Inc. MD5 (RFC 1321) - RSA Data Security Inc. MD2 (RFC 1319) - NIST SHA-1 (FIPS PUB 180-1) Modules to calculate HMAC (RFC 2104) digests are also provided. To build the extensions, unpack this distribution somewhere, create the Makefile by running 'perl Makefile.PL' and do a 'make', 'make test', and if successful 'make install'. You will need perl version 5.004 or better to install these modules. Further documentation is embedded in the individual modules. Copyright 1998-1999 Gisle Aas. Copyright 1998 Graham Barr.
