I don&#x27;t think people are any more pessimistic about back doors as they are about perpetual motion machines.<p>Let&#x27;s pause to consider this. Math works, that&#x27;s why even the NSA can&#x27;t break encryption. I wouldn&#x27;t want to tell you wrong and say that it&#x27;s impossible, it&#x27;s not, but it would take something like ten billion years to crack. Needless to say, there&#x27;s a reason why they need a backdoor, and that&#x27;s because math works.<p>However, if a backdoor were put into all electronic products, the strength of the encryption is now meaningless as any would-be attacker (government or otherwise) would just target the backdoor instead of trying to break the encryption. Why wait ten billion years for a computer to brute force the message when you could just find a flaw in something designed by the government?
