Bitcoinjs-lib: Altcoin and bitcoinjs

[coingeek]

Hi there,
I see the bitcoinjs is works perfect with Bitcoin.
can any you show me what and where the parameters to change in the code to be work perfect wirth Litecoin.
I mean the address prefix , private key prefix and any other required parameters
and it is important if there any other parameters

regards,

Fortunately a lot of these altcoins just use a version number to differentiate how addresses work. bitcoinjs-lib can accommodate this. First, take a look here to see if the network (altcoin) info is already supported: https://github.com/bitcoinjs/bitcoinjs-lib/blob/master/src/networks.js If it is not, it's just a Google search away to find the information.

To generate a Litecoin address / private key (wallet import format):

// assuming bitcoinjs-lib 1.x
var bitcoin = require('bitcoinjs-lib')
var litecoin = bitcoin.networks.litecoin

var key = bitcoin.ECKey.makeRandom()
var wif = key.toWIF(litecoin)
var address = key.pub.getAddress(litecoin).toString()

console.log('wif: ' + wif)
console.log('address: ' + address)

Should do the trick.
