Opportunistic Encryption: Bringing HTTP/2 to the unencrypted web

Cloudflare has introduced Opportunistic Encryption, a new technology that provides an additional level of security for websites not yet using HTTPS. This encryption method allows servers to accept HTTP requests over an encrypted connection, enabling the use of HTTP/2 connections for non-HTTPS sites. Combined with TLS 1.3 and HTTP/2 Server Push, Opportunistic Encryption can result in significant performance gains while also providing security benefits. The technology is now available to all Cloudflare customers, enabled by default for Free and Pro plans.
