As TLS 1.3 was ratified earlier this year, I was recollecting how it started here at Cloudflare. We made the decision to be early adopters of TLS 1.3 a little over two years ago.
A couple of weeks ago we announced support for the encrypted Server Name Indication (SNI) TLS extension (ESNI for short). As promised, our friends at Mozilla landed support for ESNI in Firefox Nightl.
Today we announced support for encrypted SNI, an extension to the TLS 1.3 protocol that improves privacy of Internet users.
TLS 1.3 (RFC 8446) was published today. This article provides a deep dive into the changes introduced in TLS 1.3 and its impact on the future of internet security.
It's no secret that Cloudflare has been a big proponent of TLS 1.3, the newest edition of the TLS protocol that improves both speed and security, since we have made it available to our customers starting in 2016.
