Editorial contextBas Westerbaan and the Hybrid TLS Handshake That Did Not Make the Certificate Post-Quantum, A browser can report `X25519MLKEM768`, derive a session secret from classical and post-quantum components, and still authenticate the server with a classical certificate signature. Both observations can be true in the same TLS 1.3 connection. Calling the whole service “post-quantum” erases the difference between them.Medium confidence
