Use react-native-get-random-values instead
import { randomBytes } from 'react-native-randombytes'
// synchronous API
// uses SJCL
const rand = randomBytes(4)
// asynchronous API
// uses iOS-side SecRandomCopyBytes
randomBytes(4, (err, bytes) => {
// bytes is a Buffer object
console.log(bytes.toString('hex'))
})
Follow the steps in the next section
You have two options depending on your needs:
Buffer objects, you can do the following:import { NativeModules } from 'react-native'
const { RNRandomBytes } = NativeModules
RNRandomBytes.randomBytes(32, (err, bytes) => {
// bytes is a base64string
})

If Automatic installation failed you, dry your tears and read on.
iOSDrag RNRandomBytes.xcodeproj from node_modules/react-native-randombytes into your XCode project.
Click on the project in XCode, go to Build Phases, then Link Binary With Libraries and add libRNRandomBytes.a
