MLS++

Implementation of the proposed Messaging Layer Security protocol in C++. Depends on C++17, STL for data structures, and OpenSSL for crypto.

Quickstart

Using the convenient Makefile that wraps CMake:

> make
> make test

Conventions

• Following Mozilla clang-format style. If you use the top-level Makefile (as suggested above), it will auto-format for you.
• General naming conventions:
  • Camel case for classes (RatchetNode)
  • Snake case for variables, functions, members (derive_epoch_keys)
  • Private member variables start with underscore (_)
  • In general, prefer descriptive names
• For cryptographic keys in particular:
  • X_key is the public key of an asymmetric key pair
  • X_priv is the private key of an asymmetric key pair
  • X_secret is a symmetric secret
