That’s why I hate the “give the government a master key” metaphor for weakening encryption. You aren’t making a master key, you’re making every lock worse. The “master key” is just knowing how to exploit the giant flaw you’ve now created in every lock, and if that knowledge escapes every lock is now worthless.

Knocking “shave and a haircut” now opens every door, let’s hope nobody else figures that out! I know! we’ll lock that information inside this “shave and a haircut” safe!
