ERROR TypeError: crypto.createHash is not a function when calling keystore.generateRandomSeed #195

The flowing error is presented when calling keystore.generateRandomSeed

ERROR TypeError: crypto.createHash is not a function at Object.Hash.sha256 (hash.js:18) at Function.KeyStore._concatAndSha256 (keystore.js:265) at Function.KeyStore.generateRandomSeed (keystore.js:291) at RegistrationComponent.newWallet (registration.component.ts:118) at Object.eval [as handleEvent] (RegistrationComponent.html:13) at handleEvent (core.js:13547) at callWithDebugContext (core.js:15056) at Object.debugHandleEvent [as handleEvent] (core.js:14643) at dispatchEvent (core.js:9962) at eval (core.js:10587)

I am using Angular and before doing some JS libraries updates (Web3, EthLightWallet and many others), it was working.

I am not sure if this is related: Importing eth-lightwallet using (import { default as lightwallet } from 'eth-lightwallet';) no longer works. But the 'require' (declare let require: any; const lightwallet = require('eth-lightwallet');) works but introduced the mentioned error.
