react-native-keychain

Keychain Access for React Native

Currently functionality is limited to just storing internet and generic passwords.

Installation

$ npm install react-native-keychain

Option: Manually

• Right click on Libraries, select Add files to "…" and select node_modules/react-native-keychain/RNKeychain.xcodeproj
• Select your project and under Build Phases -> Link Binary With Libraries, press the + and select libRNKeychain.a.

Option: With CocoaPods

Add the following to your Podfile and run pod update:

pod 'RNKeychain', :path => 'node_modules/react-native-keychain'

Option: With rnpm

$ rnpm link

Usage

See KeychainExample for fully working project example.

var Keychain = require('react-native-keychain');

var username = 'zuck';
var password = 'poniesRgr8';

// Generic Password, service argument optional
Keychain
  .setGenericPassword(username, password)
  .then(function() {
    console.log('Credentials saved successfully!');
  });

// service argument optional
Keychain
  .getGenericPassword()
  .then(function(credentials) {
    console.log('Credentials successfully loaded for user ' + credentials.username);
  }).catch(function(error) {
    console.log('Keychain couldn\'t be accessed! Maybe no value set?', error);
  });

// service argument optional
Keychain
  .resetGenericPassword()
  .then(function() {
    console.log('Credentials successfully deleted');
  });

// Internet Password, server argument required
var server = 'http://facebook.com';
Keychain
  .setInternetCredentials(server, username, password)
  .then(function() {
    console.log('Credentials saved successfully!');
  });

Keychain
  .getInternetCredentials(server)
  .then(function(credentials) {
    console.log('Credentials successfully loaded for user ' + credentials.username);
  });

Keychain
  .resetInternetCredentials(server)
  .then(function() {
    console.log('Credentials successfully deleted');
  });

Android

• Note: Android support requires React Native 0.19 or later

• on Android, the setInternetCredentials(server, username, password) call will be resolved as call to setGenericPassword(username, password, server) and the data will be saved in SharedPreferences, encrypted using Facebook conceal. Use the server argument to distinguish between multiple entries.

• Edit android/settings.gradle to look like this (without the +):

  rootProject.name = 'MyApp'
  
  include ':app'
  
  + include ':react-native-keychain'
  + project(':react-native-keychain').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-keychain/android')
  

• Edit android/app/build.gradle (note: app folder) to look like this:

  apply plugin: 'com.android.application'
  
  android {
    ...
  }
  
  dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.facebook.react:react-native:0.19.+'
  + compile project(':react-native-keychain')
  }
  

• Edit your MainActivity.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  package com.myapp;
  
  + import com.oblador.keychain.KeychainPackage;
  
  ....
  
  public class MainActivity extends extends ReactActivity {
  
    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
                new MainReactPackage(),
  +             new KeychainPackage()
        );
    }
    ...
  }
  

Todo

• iOS support
• Android support
• Storing objects as JSON
• Expose wider selection of underlying native APIs
