Build instructions
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 openssl/
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.
