I fully understand password hashing and I still had trouble following your analogy. I think the key is using as little jargon as possible and explaining the actual concepts plainly. >"Hashing" a password is a method of scrambling it that will produce the same scramble every time you do so. However two different passwords will never produce the same scramble. Could be better, but emphasizes the deterministic nature of hashing but also avoids tangential details and gotchas like collisions which aren't relevant here.
