Peer-to-Peer Network Access Point

This project allows you to create Network Access Point server and use client to connect to the server to discover other peers in network interesting in a same channel name easily. Whole communication is done via tor network with extra encryption layer for discovery, but peer communication does not have extra encryption layer, you can define it to fit your needs. Since Tor support only TCP, so this project is limited to TCP communication only.

Server Example

const path = require("path");
const p2pnapServer = require("p2pnap").Server; 
var p2pnapS = p2pnapServer({dataDir:path.join(__dirname,"server-data")});
p2pnapS.once("ready",()=>{
console.log("server ready",p2pnapS.address(),p2pnapS.port()); 
});
p2pnapS.once("error",(error)=>{
  console.error("server error",error);
  process.exit(1);
});

Client Example

const path = require("path");
const p2pnapClient = require("p2pnap").Client; 
const {onion_service_address_for_public_key} = require("p2pnap/lib/util.js");
const net = require("net");

var channel_local_port = 8001;
var service_address = "b248bb9a1202b245...onion"; // Network access point server address
var sevice_port = 80; // Network access point server port
/// create client
 var p2pnapC = p2pnapClient({
  dataDir:path.join(__dirname,"client-data"),
  channel:"test-channel-1",
  channel_port:80,
  channel_local_port:channel_local_port
}); 
p2pnapC.on("address",(addr,port,lts)=>{
  var peer = p2pnapC.open(onion_service_address_for_public_key(addr),port);
 peer.once("connect",()=>{
   console.log("outgoing peer connected to peer success");
   peer.write("hello");
   /// add peer to list in you application
 });
 peer.on("data",(data)=>{
   console.log(data.toString());
 });
 peer.once("error",(err)=>{
   console.log("peer connection error",err);
 });
 peer.once("close",()=>{
   console.log("peer connectio close");
 });
});
p2pnapC.once("ready",()=>{
console.log("client ready",p2pnapC.address(),p2pnapC.port()); 
p2pnapC.scan(service_address,sevice_port,(err)=>{
  console.log("scan finished",err);
});

});
p2pnapC.once("error",(error)=>{
  console.error("Client error",error);
  process.exit(1);
});
/* create server for incoming connection for channel on channel local port so we can accept 
incoming connections form peers for our channel
*/
var server = net.createServer((sock)=>{
  console.log("incoming peer connection",sock.remoteAddress);
  sock.on("data",(data)=>{
    console.log("received",data.toString(),"from peer");
    sock.write("You said: '"+data.toString()+"'");
  });
  sock.once("error",()=>{
  });
  sock.once("close",()=>{
  });
});
server.listen(channel_local_port,"localhost");
