torrent-peerid

torrent-peerid is a lightweight Deno library for decode and encode peerid for BitTorrent protocol.

Usage

decode

import { decode } from "https://deno.land/x/dt_torrent_peerid/mod.ts";

// decode Azureus style peerid
let result = decode('-AZ2060-Mb?3kG/qpRd^')

// output : { code: 'AZ', name: 'Azureus' , version: '2.0.60' }
console.log(result)

// decode Shadow style peerid
result = decode('S58B-----IWl4Z*v.Jul')

console.log(result)
// output : { code: 'S5', name: 'Shadow', version: '5.8.11' }

encode

import { encodeAzStyle, encodeShadowStyle } from "https://deno.land/x/dt_torrent_peerid/mod.ts";

// encode Azureus style peerid
let result = encodeAzStyle('AZ', '2.0.60')
console.log(new TextDecoder().decode(result))

// output : '-AZ2060-K4vXK}wDsk"7'

// encode Shadow style peerid
result = encodeShadowStyle('C', '5.8.11')
console.log(new TextDecoder().decode(result))

// output : 'C58B-----IWl4Z*v.Jul'
