I absolutely hate the idea of government justifying having control of everything and everyone by saying it's trying to protect you.

What if private key and encryption/decryption is only done on dedicated device that does not utilise major processor chipsets? Such as a scientific calculator type device?

[loveredmoon]

I dont understand the shared key, after creating the shared key, is the shared key the same for each end? how does the shared key be used?
