Using Guids as serial keys for applications I'm creating the registration system right now for File Phantom and originally I was going to have a semicomplex key that would be encrypted but then could by decrypted and broken down to give me information but after a bit, I realized that would just be too complex.

So, why not just use Guids? I'm going to be authenticating the registration key against a database anyways.  ¶ 7:33 PM
