+randombytes from node that works in the browser.  In node you just get crypto.randomBytes, but in the browser it uses .crypto/msCrypto.getRandomValues
+
+```js
+var randomBytes = require('randombytes');
+randomBytes(16);//get 16 random bytes
+randomBytes(16, function (err, resp) {
+  // resp is 16 random bytes
+});
