hyperdht-hugin

A fork of hyperdht with added connection signature verification for Hugin Messenger.

npm install hyperdht-hugin

What's different?

This fork adds a signature verification layer to DHT connections:

• sig - A signature proving ownership of shared group keys
• dht_keys - DHT keypair for connections
• keychain - Shared keychain for signature verification

This prevents unauthorized connections even if topics are leaked.

Usage

import DHT from 'hyperdht-hugin'

// Create DHT with signature verification
const node = new DHT({
  bootstrap: ['host:port']
}, sig, dht_keys, keychain)

Server

const server = node.createServer()

server.on('connection', function (socket) {
  console.log('Remote public key', socket.remotePublicKey)
  process.stdin.pipe(socket).pipe(process.stdout)
})

const keyPair = DHT.keyPair()
await server.listen(keyPair)

Client

const socket = node.connect(publicKey)

socket.on('open', function () {
  // socket fully open with the other peer
})

process.stdin.pipe(socket).pipe(process.stdout)

API

The API is identical to hyperdht with the extended constructor:

new DHT(options, sig, dht_keys, keychain)

| Parameter | Description | |-----------|-------------| | options | Standard hyperdht options (bootstrap, keyPair, etc.) | | sig | Signature proving group membership | | dht_keys | Keychain providing DHT keypair via .get() | | keychain | Keychain for verifying signatures via .verify() |

For full API documentation, see the original hyperdht docs.
