The Illustrated TLS Connection
Published at https://tls13.ulfheim.net
site/: page source for the finished product
server/main.c: server code
client/main.c: client code
boringssl/: patch of boringssl that removes any random aspects of the documented connection
captures/: PCAP and keylog files
See also https://github.com/syncsynchalt/illustrated-tls for a TLS 1.2 version of this project.
If you'd like a working example that reproduces the exact handshake documented on the site:
git clone https://github.com/syncsynchalt/illustrated-tls13.git cd illustrated-tls13/ cd boringssl/ make cd ../server/ make cd ../client/ make
Then open two terminals and run
./server in the server/ subdir and
./client in the client/ subdir.
This has been shown to work on MacOS 10.14 and various Linuxes and only has a few easy-to-find dependencies: gcc or clang, golang, cmake, make, patch.
