If we guess right, the handshake completes in one round trip. Guess wrong, and the origin replies with a HelloRetryRequest , we start over, and the connection costs two round trips. For years, our guess was the same for every origin on the Internet: X25519 . Widely supported, but as it turns out, suboptimal for roughly 30% of the origin connections we've since measured. Today we're announcing Automatic Key Exchange , an extension of Automatic SSL/TLS that replaces the guess with a measurement. We probe each origin to learn which key agreement algorithms it supports and prefers, then lead with that algorithm on the first try, preferring the post-quantum hybrid X25519MLKEM768 wherever the origin can speak it.
