hdwallet's Issues

isValidSeed is not working correct

I had hard times convincing Colu SDK to accept privateSeed generated from mnemonic (BIP39, implementation by Bitcore). It failed on isValidSeed step saying "privateSeed should be a 256 bits hex (64 chars), if you are using WIF, use privateSeedWIF instead.". If I comment out this check, everything works correct.

Here is the code to test. It derives an address from mnemonic using Bitcore and then tries to do the same with Colu. Same addresses are expected to be derived.

var Colu = require('colu');
var bitcore = require('bitcore-lib');

var Mnemonic = require('bitcore-mnemonic');

var mnemonic = new Mnemonic('legal winner thank year wave sausage worth useful legal winner thank yellow');

// generate address from mnemonic
var hdPrivateKey = mnemonic.toHDPrivateKey();
var accountKey = hdPrivateKey.derive(44, true).derive(0, true).derive(0, true);
var addr = accountKey.derive(0).derive(0).privateKey.toAddress();
console.log(addr);

// try do the same with Colu
var seed = mnemonic.toSeed();
var seedHex = seed.toString('hex');

var settings = {
    apiKey: 'Your API key',
    network: 'mainnet',
    privateSeed: seedHex // <-- this is not going to work?!
}

var colu = new Colu(settings);
colu.on('connect', function () {
    console.log(colu.hdwallet.getAddress()); // <-- should be the same as addr
});
colu.init();
