I've written up a public key encryption algorithm I came up with and some thoughts on it at http://www.gawth.com/bram/essays/simple_public_key.html [It doesn't smell that secure, but I've only just glanced at it. --Perry] I've also posted some very provocative conjectures at http://www.gawth.com/bram/essays/wild_cryptographic_conjectures.html You might find them interesting reading. -Bram
