Crypto.randomBytes is not a function–an uncaught TypeError

Hi there,

The error I am receiving: Crypto.randomBytes is not a function seems to derive from the ./~/es7-reflect-metadata/src/helper/gen-randombytes.ts file

gen-randonbytes.ts file includes:

import * as crypto from "crypto";
import {BufferLike} from "./interfaces";

export function genRandomBytes(size: number): BufferLike {
  return crypto.randomBytes(size); //Here is where the error occurs
}

I am running: es7-reflect-metadata: ^1.5.5, typescript: 1.7.5, angular2: 2.0.0-beta.7, npm: 3.8.0, node: 5.6.0

Thanks in advance for your help!

Simon
