Detailed Description

MD5 block cipher. Stands as a foundation for MD5 hashes.

Encrypt implemented directly from the RFC as found at http://www.faqs.org/rfcs/rfc1321.html

Decrypt is a straight-forward inverse

In MD5 terminology:

• plaintext = AA, BB, CC, and DD
• ciphertext = A, B, C, and D
• key = M^(i) and X
