React Native Cipher

React Native Cipher is a library that provides encryption and decryption functionalities for React Native applications.

Installation

yarn add @finan-me/react-native-cipher

Additional Dependencies

To ensure React Native Cipher works properly, you should also install the following libraries:

react-native-randombytes

yarn add react-native-randombytes

node-libs-react-native

yarn add node-libs-react-native

Usage

This package exports a mapping of absolute paths to each module implementation, keyed by module name. Modules without React Native compatible implementations are null.

These modules can be used with React Native Packager's metro.config.js or Webpack's resolve.alias.

Usage with React Native Packager Add a metro.config.js file in the root directory of your React Native project and set resolver.extraNodeModules:

// metro.config.js
module.exports = {
  resolver: {
    extraNodeModules: require('node-libs-react-native'),
  },
};

Globals

Node has certain globals that modules may expect, such as Buffer or process. React Native does not provide these globals. The node-libs-react-native/globals module in this package will shim the global environment to add these globals. Just require (or import) this module in your app before anything else.

import 'node-libs-react-native/globals';
