Diffie-Hellman Key Exchange

Would anyone be interested in making a DH key exchange purely for recreation? Pick whatever large prime you want to be public, and then pick you favorite base number. The higher the number, the better-but don't make it too high!

I assume that DH can work for more than 2 people?

What do you want to use it for? Just sending nonsense messages, or having public encrypted discussions?

I could set one up with you, but I don't see the point.

I guess the purpose is just to try out the mechanism. For real communication, I suppose using something like PGP would make more sense. I can admit I've never sent or received an encrypted message (except through SSL or other mechanisms that involved no choice by me)

Yes, the main intent will just be to try it. I suppose there ought to be some basic secret message to decrypt with the secret key at the end. But what would the number of the secret key stand for to decrypt?

Is anyone interested in trying it out?
