With growing focus on the threat quantum computing poses to crucial and widely used forms of encryption, @filippo wants to make one thing perfectly clear: Contrary to popular mythology that refuses to die, AES 128 is perfectly fine in a post-quantum world

@dangoodin @filippo The key is to transmit the symmetric key securely. And never reuse.

@dangoodin @filippo This is good. We don't have to tell people "in addition to changing your public key algorithm and keys, you also have to upgrade your AES-128 to AES-256." Not that it's hard, but the less work that can be made of Post-Quantum Readiness, the higher the chances of getting compliance.
