About

SSP21-CPP is a platform-neutral reference implementation of the SSP21 protocol written in modern C++ provided under the BSD-3 clause license.

In addition to this user guide, there is also an auto-generated API reference with details on all the public classes and functions.

Features

• Scalable asynchronous design backed by arbitrary event loop (examples based on ASIO)
• Pluggable cryptographic backend with libsodium implementation provided
• Secure zero-copy (un)parsers generated from a model of the message grammars
• Implements all of the key modes defined in SSP21
  • shared secrets
  • quantum key distribution (QKD)
  • pre-shared public keys
  • industrial certificates

C++11/14

The core library should compile for any platform that has a compiler that implements C++11/14 features:

• Ownership using std::unique_ptr and std::shared_ptr
• Time management using std::chrono::steady_clock
• Lambda expressions are used throughout the implementation
• Variadic templates are applied specifically to make parsing/formatting more expressive

Minimum Compiler Versions

• Visual Studio 2017
• GCC 4.9.x
• Clang 3.4
