American police and spies love the idea of back door access to encrypted data that lets them snoop on suspicious types, but many will tell you that they're wildly optimistic. Even if you don't mind the implication that the government has a right to spy on anyone, this could easily introduce a flaw that any attacker can use. National Security Agency chief Michael Rogers thinks there's a happy medium, however. At a recent speech, he called for a "front door" encryption key that would provide access, but would be broken into pieces that prevents any one agency or person from getting in. This theoretically prevents thieves (and less than scrupulous authorities) from grabbing your data, but still lets officials look around when they have permission.
