* generation of message digests (hash values, checksums): md2,
md5, sha/shs, sha-1, haval, ripemd-128, -160, crc (polynomial
used by pgp), adler (based upon zlib);
* conversion to and from various data encodings: uuencoding,
base64-encoding, or ascii85-encoding, and binary, octal, or
* an error-correcting reed-solomon encoder/decoder;
