# react-native-randombytes ## Usage Note: only the asynchronous API is supported, due to the limitations of having to go over the RCTBridge, and there being no secure RNG in JavaScriptCore (Math.random is a bit of a joke in the industry) ```js var randomBytes = require('react-native-randombytes') randomBytes(4, (err, bytes) => { console.log(bytes.toString('hex')) }) ``` ## Installation ### `iOS` * Drag 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` Confused?
