' DESCRIPTION:
' Derived from the RSA Data Security, Inc. MD5 Message-Digest Algorithm,
' as set out in the memo RFC1321.
'
' This class is used to generate an MD5 'digest' or 'signature' of a string. The
' MD5 algorithm is one of the industry standard methods for generating digital
' signatures. It is generically known as a digest, digital signature, one-way
' encryption, hash or checksum algorithm. A common use for MD5 is for password
' encryption as it is one-way in nature, that does not mean that your passwords
' are not free from a dictionary attack. If you are using the
' routine for passwords, you can make it a little more secure by concatenating
' some known random characters to the password before you generate the signature
' and on subsequent tests, so even if a hacker knows you are using MD5 for
' your passwords, the random characters will make it harder to dictionary attack.
'
' *** CAUTION ***
' See the comment attached to the MD5 method below regarding use on systems
' with different character sets.
