Product code/serial number generator

A class is needed to generate a product key/serial number type string that is unique. Class need to be developed in . NET (preferably VB), and should contain 2 methods, one for generating and one for validating.

Method 1 (length, optional characters string)

Generate unique alpha-numeric string of the specified length, optionally including characters passed into method. The method won’t generate the same string twice, and some type of checksum or other approach will be used to prevent the changing of a character to produce another valid string.

Method 2 (key string)

Validates string to determine if it’s a valid key; not that it has necessarily been generated.
