⚠️ Deprecated

This package is now deprecated in favor of expo-crypto, which provides the same functionality. To migrate, replace all imports from expo-random with imports from expo-crypto.

Provides a native interface for creating strong random bytes. With Random you can generate random values to address use cases that other APIs like the web's crypto.getRandomValues and Node's crypto.randomBytes might address.

Installation in managed Expo projects

For managed Expo projects, please follow the installation instructions in the API documentation for the latest stable release.

You can add a polyfill for the web's crypto.getRandomValues by installing expo-standard-web-crypto and importing it in SDK 39 and higher:

import { polyfillWebCrypto } from 'expo-standard-web-crypto';

polyfillWebCrypto();
// crypto.getRandomValues is now globally defined

Other libraries like react-native-get-random-values may work too.

Add the package to your npm dependencies

npx expo install expo-random

Configure for iOS
