title: react-native-bcrypt: Secure PRNG
body: <p><code>react-native-bcrypt</code> (<a href="https://github.com/emiraydin/react-native-bcrypt" rel="nofollow noreferrer">link</a>) throws the following warning.</p>
  
  <pre><code>Using Math.random is not cryptographically secure! Use bcrypt.setRandomFallback to set a PRNG.
  </code></pre>
  
  <p>Using <code>react-native-crypto</code> (<a href="https://github.com/mvayngrib/react-native-crypto" rel="nofollow noreferrer">link</a>) is a potential solution but feels overly complicated as one has to <code>nodify</code> the project. Is there a simpler PRNG that can be set on bcrypt?</p>
