Scuttlebutt BoxStream

An implementation of the box stream protocol used by Scuttlebutt for secure communication between peers.

Usage

To create a pair of boxer/unboxer:

var client = new Client(network_key, server_publicKey, client_keypair);

var a = client.ClientEphemeralPubKey;
var b = client.ServerEphemeralPubKey;

var (client_boxer, client_unboxer) = BoxStreamBuilder.Build(
  client.ClientDerivedSecret,
  server_publicKey,
  client_keypair.PublicKey,
  network_key,
  a, b
);

After the creation of the Boxer and Unboxer they can be used for sending:

var plain = System.Text.Encoding.Unicode.GetBytes("hello world");

var msg = client_boxer.Box(plain);

And receiving:

var netstream = NetworkStream(inbound_conn, true);

var reply = await receiver.Unbox(netstream);
Console.WriteLine(reply);
