' description:
' this is a class which encapsulates a set of md5 message digest functions.
' md5 algorithm produces a 128 bit digital fingerprint (signature) from an
' dataset of arbitrary length. for details see rfc 1321 (summarized below).
' this implementation is derived from the rsa data security, inc. md5 message-digest
' algorithm reference implementation (originally written in c)
