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:

$3

Takes a length, the number of bytes to generate, and returns a Promise that resolves with a Uint8Array.

``javascript
import { generateSecureRandom } from 'react-native-securerandom';

generateSecureRandom(12).then(randomBytes => console.log(randomBytes));
`

Installation

$ yarn add react-native-securerandom

$3

$ react-native link react-native-securerandom

$3

#### iOS

##### With Cocoapods
1. Add pod 'RNSecureRandom', :path => '../node_modules/react-native-securerandom' to your Podfile (changing your node_modules path as appropriate)

- Add import net.rhogan.rnsecurerandom.RNSecureRandomPackage; to the imports at the top of the file
- Add new RNSecureRandomPackage() to the list returned by the getPackages() method
2. Append the following lines to android/settings.gradle:
`
include ':react-native-securerandom'
project(':react-native-securerandom').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-securerandom/android')
`
3. Insert the following lines inside the dependencies block in android/app/build.gradle:
`
compile project(':react-native-securerandom')
`

#### Windows

See react-native-windows
