everyone is someone's bad guy

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!

One thing I don’t like about the “master key” metaphor: I do lockpicking as a hobby. And locks built for a master key are easier to pick, because you can open them with two keys. It seems kinda obvious when you think about it. (You gotta be careful when picking mastered locks though, the master wafers can fall into the keyway and permanently destroy the lock.)
