The RSA algorithm is patented and can't be used without paying royalties to the patent holders. Otherwise, it's stealing another persons ideas. You are welcome to get a PhD in Math and come up with a different algorithm that is simple, easy to implement, and relatively secure. Then you can give it away, or patent it and make money on it. -- Michael Rutman | moose@svcdudes.com Cubist | makes me a NeXT programmer Software Ventures | maker of MicroPhone II #include <std.disclaimer>
