> To me it just proves that they don't understand the very basic of how encryption works. No? You can have encryption with “secure” backdoors. (In the sense that only an entity with the backdoor key could use it.) For example, let’s say you were going to symmetrically encrypt some data with a certain private key. You can add the key to the data, asymmetrically encrypted with the public backdoor key. (You can improve on this with a salt to retain public anonymity.) As a theoretical matter, cryptography can do this. As a practical matter…that’s a separate question of human structures and behaviors. But you don’t need cryptography to understand that.
