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

A convenience Makefile is included to avoid the need to remember a bunch of CMake parameters.

> make        # Configures and builds the library 
> make dev    # Configure a "developer" build with tests and checks
> make test   # Builds and runs tests
> make format # Runs clang-format over the source

• 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
