IIRC, I remember reading that the NSA has cipher(s) where the decryption 'algorithm' is completely than the one for encryption, i.e., just because you have the decryption code doesn't mean you can encrypt.
- m4rtink 3y agoSo normal public key cryptography? ;-)
- throw0101c 3y agoNo, this is for symmetrical encryption. So think something like AES, but where the 'distributor' encrypts something, gives you a key and an algorithm, and you can decrypt it. But you cannot use the same algorithm to encrypt to send back anything. For the life of me I can't remember where I read it (which book), so have never been able to dig into it more.
