Is quantum computing a major issue for symmetric keys? I thought it was primarily an issue with public-keys?

- knorker 1y agoThe File Key is symmetric, but the header having recipient implies this is public key crypto. So break the public key crypto (e.g. X25519), and you don't need to crack the symmetric key. Also 128 bit? That's not quantum safe either, thanks to Grover's algorithm.
