Client / Sign and extract DER

var clientSign = function(tx, xpriv, n) {
  //Derive proper key to sign, for each input
  var privs = [],

var b = require('bitcore');

var priv = new b.PrivateKey();
var pub = new b.PublicKey(priv);

var inputs =

Joining a wallet
================

Creator (C) <-> Joining Peer (J)

(J)
  <- Hello (secret random, peerPubkey) encrypted with creatorPubkey

(C)
  (async._addConnectedPeer, emit 'connect', w.sendWalletId)

1. Test only one class at time. Use sinon.stub (.returns & .yields) to create on the fly mockups for dependencies.
2. Test the API Only. Never access class internals for checking / setting values. Use the API, this prevents to brake test in the future. E.g.:

  class.setName('name');
  class.name.should.equal('name'); // Wrong
  clase.getName().should.equal('name'); //Right

var opts = {
  blockchain: new Blockchain(...),,
  storage: localstorage / insight / drive,
  networking: new Async(...),
};

Identity.create(email, password, opts, function(err, iden){
