Map a BitTorrent peer ID to a human-readable client name and version

Also works in the browser with browserify!

This module is used by WebTorrent.

install

npm install bittorrent-peerid

usage

const peerid = require('bittorrent-peerid')
const parsed = peerid('-AZ2200-6wfG2wk6wWLc')

console.log(parsed.client, parsed.version)

The parsed peerid object looks like this:

{
  client: 'Vuze',
  version: '2.2.0.0'
}

bittorrent-peerid can parse peer ids encoded in the following formats:

  • a 20-byte Buffer
  • a 40-character hex string
  • an arbitrarily-sized human-readable utf8 string (must decode to a 20-byte Buffer)

If an unknown peer id is passed in, the returned client will be unknown.
