More information:
Various ports of the MD5 RSA Reference Implementation. This includes a VB Native Class, a C DLL (with VB wrapper), and a
java port.
The MD5 algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. It is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA.
