react-native-securerandom
A library to generate cryptographically-secure random bytes. Uses SecRandomCopyBytes
on iOS, SecureRandom
on Android and System.Security.Cryptography.RandomNumberGenerator
on Windows.
Usage
The library exports a single function:
generateSecureRandom(length: number) => Promise<Uint8Array>
Takes a length, the number of bytes to generate, and returns a Promise
that resolves with a Uint8Array
.
import { generateSecureRandom } from 'react-native-securerandom';
generateSecureRandom(12).then(randomBytes => console.log(randomBytes));
