since ChaCha and Salsa are based on irreversible operations, quantum
calculations just not work on them, and the same is doubtless true for
many other symmetric encryption protocols. They should be completely
Some symmetric encryption algorithms will be affected. I don't
understand AES well enough to say whether it will be affected or not.
