This package is based on react-native-secure-storage and did some customized.

Getting started

$ npm install react-native-secure-storage --save

or

$ yarn add react-native-secure-storage

Mostly automatic installation

$ react-native link react-native-secure-storage

Manual installation

iOS

  1. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]
  2. Go to node_modulesreact-native-secure-storage and add RNSecureStorage.xcodeproj
  3. In XCode, in the project navigator, select your project. Add libRNSecureStorage.a to your project's Build PhasesLink Binary With Libraries
  4. Run your project (Cmd+R)<

Android

  1. Open up android/app/src/main/java/[...]/MainActivity.java
  • Add import com.aaxis.RNSecureStoragePackage; to the imports at the top of the file
  • Add new RNSecureStoragePackage() to the list returned by the getPackages() method
  1. Append the following lines to android/settings.gradle:
    include ':react-native-secure-storage'
    project(':react-native-secure-storage').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-secure-storage/android')
    
  2. Insert the following lines inside the dependencies block in android/app/build.gradle:
      compile project(':react-native-secure-storage')
    

Usage

import SecureStorage, { ACCESS_CONTROL, ACCESSIBLE, AUTHENTICATION_TYPE } from 'react-native-secure-storage'
 
async() => {
  const config = {
    accessControl: ACCESS_CONTROL.BIOMETRY_ANY_OR_DEVICE_PASSCODE,
    accessible: ACCESSIBLE.WHEN_UNLOCKED,
    authenticationPrompt: 'auth with yourself',
    service: 'example',
    authenticateType: AUTHENTICATION_TYPE.BIOMETRICS,
  }
  const key = 'someKey'
  await SecureStorage.setItem(key, 'some value', config)
  const got = await SecureStorage.getItem(key, config)
  console.log(got)
}

Methods

This library has now implemented getItem, setItem, removeItem and getAllKeys methods of AsyncStorage from React Native. It doesn't support callback and replaced the callback param with an option param.

In addition, this library has a getSupportedBiometryType() method which Returns one of BIOMETRY_TYPE indicating which biometry type the device supports, and a canCheckAuthentication([{ authenticationType }]) method which checks whether the specified authenticationType is available.
