bitmessage

JavaScript Bitmessage library for both browserify and node. The goal of this project is to implement Bitmessage protocol v3 for both platforms at the maximum possible level (we still can't create TCP connections or listen for incoming connections in the Browser but the Proof of work and crypto is fully doable).

Public library API is currently in alpha stage, breaking changes are very likely to happen.

Implementation details

With the help of browserify bitmessage provides different implementations for Browser and Node.js with the same API. Because WebCryptoAPI defines asynchronous promise-driven API, implementation for Node needs to use promises too.

• Use Node.js crypto module/library bindings where possible
• Use WebCryptoAPI where possible
• Promise-driven API

    console.log("New random Bitmessage address:", str);
  });
});
