How would this work without breaking cryptography? The whole point of a good cipher is that the algorithm can be public and widely understood, and all that’s needed for it to be secure is for the private key to be private. A cipher that has some backdoor -master key- is by design insecure and no sane person should use it. Security through obscurity doesn’t work, trying to keep the algorithm private won’t work, someone sooner or later will break it.

It can’t work without breaking cryptography. Any system with backdoors in it is fundamentally insecure.
