first, let start with some properties of the audio CDs what you need on a protection is to know a fixed value find something that is different in a copy audio tracks do it for you did you guys ever burn an audio cd? ok.. if you read the TOC of the CD, the original and the copy are never the same if you check the separation between tracks, they're not the same so, there you have a way to know if you're dealing with a copy problem is, that cd checks are easy to remove so what we did is take that track separation as half of a decyption key and the other half of the key came from a serial number you input that key, once built, deencrypted a portion of our program the encryption was DES2, wich is not all impressive but works also you can read the HD brand the guys is using so once decrypted, we encrypted the thing again with the HD brand so the program will be attached to that machine well, you guys might not need that but basically that was it its been on the market for 1 year no cracks yet
