There is a problem in crypto.js

[jiangbo0216]

let assert = require('assert')
let bitcoin = require('bitcoinjs-lib')
let dhttp = require('dhttp/200')

// deterministic RNG for testing only
// function rng () { return Buffer.from('zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz') }

function rng () {
    return Buffer.from('YT8dAtK4d16A3P1z+TpwB2jJ4aFH3g9M1EioIBkLEV4=', 'base64')
  }

// TODO: remove
let baddress = bitcoin.address
let bcrypto = bitcoin.crypto
function getAddress (node, network) {
  network = network || bitcoin.networks.bitcoin
  return baddress.toBase58Check(bcrypto.hash160(node.publicKey), network.pubKeyHash)
}

    var keyPair = bitcoin.ECPair.makeRandom({ rng: rng })
    console.log(keyPair)
    var address = getAddress(keyPair)

keyPair don't have publicKey

@JQiMeng this is using master branch, yes?

What does

console.log(keyPair)

Print?

[dabura667]

use node.getPubkeyBuffer() instead of node.publicKey

[dcousens]

@dabura667 our example links should ref the latest release, probably

[jiangbo0216]

thank your help, I use the command ( npm install bitcoinjs-lib) to install ,is it stable?

and i see code as follows：

ECPair.prototype.getAddress = function () { return baddress.toBase58Check(bcrypto.hash160(this.getPublicKeyBuffer()), this.getNetwork().pubKeyHash) } so we can Modify the code as follows：

    var keyPair = bitcoin.ECPair.makeRandom({ rng: rng })
    keyPair.getAddress()
    rather then   var address = getAddress(keyPair)

is this right?

[dcousens]

@JQiMeng that is stable. And that is right.

The master branch on this repository is about to release to 4.0.0.

Please see https://github.com/bitcoinjs/bitcoinjs-lib/blob/v3.3.2/test/integration/addresses.js#L13-L16 for the examples for 3.3.2 (latest release).
