Generate/Validate License Keys Based on User Name

This class is loosely based on the one by Phil Fresle at http://www.freevbcode.com/ShowCode.ASP?ID=1639. Phil's class allows you to generate license keys, such as the CD keys on the case of most Microsoft software. The major difference in this implementation is that it includes an expiration date. In addition the KEYCODE is generated on the fly using the Soundex of the Username AND the Date.

Note: Upgraded on 01/27/2001 to include an encryption module.
