> Cryptography only works in transit. If you are in control of one of the endpoints of a communication, Cryptography is NOTHING.

In principle this is true, but if the endpoint you "control" requires an engineering degree and expensive equipment to analyze, you're effectively not in control. You cited the proliferation of jailbroken phones, but jailbreaking procedures usually find other bugs with which to bypass the encryption --- they can't do anything against the encryption itself.

This is even worse than that: you are not in effectively not in control because of the cost, but given the right incentive an opponent can take control in a way that locks you down completely out of control.
