I need to be able to Generate a 25 character product key based on a date and a string
I need to beable to extract the date {the date tells me if the serial has expired} but the string is just the app ID
I want the product code to only use CAPS A-Z and numbers 0-9 (like m$ so its simple for customers :D)
anyone got any thinks or examples to get me started - im not looking for a free ride, i want to actually learn how to do this for some other appz.
