"We don’t need any new NSA-proof protocols. Any well-designed, appropriately-deployed protocol is NSA-proof."
Or so the NSA would have us believe. Even as far back as Caesar, there has been a conflict between the codemakers and the codebreakers. It's in the NSA's interest to have people believe there are NSA-proof protocols. Codemakers should keep trying to push the state-of-the-art in encryption. If they aren't, they're not doing their jobs.
