Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

A Readable TLS 1.3 Specification posted December 2018

I've been experimenting at www.davidwong.fr/tls13 with a "readable" TLS 1.3 specification.

If you take a look at the original RFC: 8446 you will see that it's not that pretty.

The page I created contains many things to simplify one's life in reading the dense specification:

erratas are applied
references can be previewed
figures were re-created
etc.

For example, here is the state machine of the TLS client now:

client state machine tls 1.3

And here is the server:

server state machine tls 1.3
