	You may want to be careful using quartz, or any other Hidden Fields 
Equation based systems, as there is an existing patent that seems to 
cover a wide range of their application.  If you find something that is 
not patent encumbered let us all know.

For generating license codes, you probably want to use a signature

in Crypto++, around 320 bits.
