All encryption is "security through obscurity". The parameter space is very large. The key is somewhere in it. You have access to the whole space, but no clue as to where the key is. Good luck finding the key. > Instead it was originally meant as "if your only security is obscurity, it's bad". Since all security is essentially "through obscurity" somehow, I would simply reframe that into the onion model. Good security is like an onion, it has many layers. When you only have one layer, that's bad security.
