As the share of #postquantum encrypted traffic approaches 50% globally, Radar now checks your browser for PQ support.
Visiting https://radar.cloudflare.com/adoption-and-usage#post-quantum-encryption will show you if your browser supports PQ encryption, and if it does, which key agreement it is using.
We're excited to see the release of Signal's new post-quantum ratcheting protocol, SPQR!
We are proud to have collaborated with the Signal team on the formal analysis of the design and implementation of this new feature.

🔐 Signal adds post-quantum encryption with SPQR to defend against future quantum threats 🧪
SPQR forms a Triple Ratchet, mixing keys for hybrid security 🧬
Built with PQShield & NYU, verified via ProVerif & hax ✅
Rolling out gradually—just keep your app updated 📲

"We've got post-quantum handshakes, stories and money transfer experiments, but still no SDK, no APIs, no bots. The official libsignal library is undocumented and incomplete. Large parts of functionality are still buried on clients. Don't get me started on "but they have published all protocol specs on their website, go on and roll your own library"! That's not how you run a product. It's borderline negligent for a platform used by millions."

I was reading the #Signal blog post about their new #postquantum ratchet, which they nicknamed SPQR. They kept talking about a user "speaking SPQR", and my Percy-Jackson-trained brain knows that SPQR was a Roman motto, so I just kept picturing Alice and Bob speaking Latin.
