p2plib 1.1.0+0

Tooling for encrypted udp datagram peer to peer communication

P2Plib Dart

P2Plib is a minimalistic library for peer-to-peer communication over UDP. Key features:

• written in pure Dart;
• no legacy, the project is simple and self-sufficient.

Installation

Clone the project:

git clone [e-mail]:GuardianLabs/p2plib-dart.git

Usage

The main entity is the Router - and it also serves as the entry point for the incoming packets. The Router is assigned handlers, each of which:

• subscribes to its own type of message (topic);
• defines how to react to the incoming message (e.g. invoke a callback).

Peers are identified by 64-byte public keys: a 32-byte encryption key + a 32-byte public key for signing.

Basic Handlers

• EchoHandler, similar to ping;
• BootstrapHandler, used to introduce peers through the server (server code is given in the examples).

Note: To create a custom handler, implement the TopicHandler interface.

To use bootstrap server

The peers are introduced to each other through the bootstrap server accessed by pre-defined ip-port tuple. If you want to run your own bootstrap service, you can run it in the Docker container as follows:

docker build -t p2pbootstrap .
docker run --rm -d --network host p2pbootstrap

Usage examples

You can see an example of using this library in practice in our project: https://github.com/GuardianLabs/guardian-keyper
