Utility to generate SHA256 Message Digest from files.

This SHA256 Utility is based on the FreeBSD SHA2 implementation
by Aaron D. Gifford, view the included source for more information.


V1.2 (01.06.2008) - more code cleanup, using amiga functions instead
                    of the *nix ones. Binary size is now 17636 Bytes.

V1.1 (14.04.2008) - changed code base to the FreeBSD SHA2 implementation,
                    which results in a smaller and faster binary.

                  - there was a bug in version 1.0 which caused that
                    checksums from files bigger than 512MB are wrong (this
                    was related to the former SHA2 implementation I've used).

V1.0 (11.04.2008) - initial version
