Cloudflare Automatic Key Exchange
Automatic Key Exchange: faster, post-quantum secure origin handshakes for 45 billion daily connections (and counting)
Protects ASEAN websites and services with quantum-resistant encryption without requiring server-side changes.
Cloudflare has introduced Automatic Key Exchange to probe TLS 1.3-capable customer origins for supported key agreement algorithms. The system prioritizes the most secure algorithm when connecting to origins, with preference for post-quantum connections where supported. This service handles 45 billion daily connections and counting.
Automatic Key Exchange: faster, post-quantum secure origin handshakes for 45 billion daily connections (and counting)
Automatic Key Exchange probes TLS 1.3-capable customer origins to learn which key agreement algorithms they support. We then lead with the most secure algorithm when connecting to the origin, preferring post-quantum connections wherever the origin supports it.
