react-native-keychain

Keychain Access for React Native

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

❗ Enable Keychain Sharing entitlement for iOS 10

For iOS 10 you'll need to enable the Keychain Sharing entitlement in the Capabilities section of your build target. (See screenshot). Otherwise you'll experience the error shown below.

Error: {
    code = "-34018";
    domain = NSOSStatusErrorDomain;
    message = "The operation couldn\U2019t be completed. (OSStatus error -34018.)";
}

Installation

$ npm install --save react-native-keychain

Check out the "releases" tab for breaking changes and RN version compatibility. v1.0.0 is for RN >= 0.40

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 react-native link

$ react-native link

Usage

See KeychainExample for fully working project example.

import * as Keychain from 'react-native-keychain';

const username = 'zuck';
const 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
const server = 'http://facebook.com';
Keychain
  .setInternetCredentials(server, username, password)
  .then(function() {
    console.log('Credentials saved successfully!');
  });

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

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

Keychain
  .requestSharedWebCredentials()
  .then(function(credentials) {
    if (credentials) {
      console.log('Shared web credentials successfully loaded for user ' + credentials.username);
    } 
  })

Keychain
  .setSharedWebCredentials(server, username, password)
  .then(function() {
    console.log('Shared web credentials saved successfully!');
  })

Android

Option: With react-native link

$ react-native link and check MainApplication.java to verify the package was added.

• 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.

Option: Manually

• 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 MainApplication.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()
        );
    }
    ...
  }
