That’s why Cloudflare builds infrastructure that helps developers bake privacy into their apps. Oblivious HTTP (OHTTP) is an IETF standard designed to enable app backends to receive HTTP requests without seeing user IP addresses.
This fall, we’re launching the Cloudflare OHTTP Gateway. Customers will be able to enable our new OHTTP Gateway as a paid add-on to their zone and start receiving OHTTP traffic with just a few clicks. Register through our form to join our waitlist. Read on to learn more.
With OHTTP, requests travel through two independently-operated hops: a relay and a gateway. An OHTTP relay blindly forwards encrypted requests in order to hide client identifiers from app servers. An OHTTP gateway performs the cryptographic work of decapsulating encrypted requests and encapsulating responses such that app servers can handle OHTTP requests as if they were plain HTTP. The separation of trust between relay and gateway is critical: it ensures that no single party sees both client identifiers and request contents.
