react-native-secure-key-store

React Native Library for securely storing keys to iOS and Android devices in KeyChain and KeyStore respectively

Getting started

$ npm install react-native-secure-key-store --save

$ yarn add react-native-secure-key-store

Mostly automatic installation

$ react-native link react-native-secure-key-store

Manual installation

iOS

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ react-native-secure-key-store and add RNSecureKeyStore.xcodeproj
In XCode, in the project navigator, select your project. Add libRNSecureKeyStore.a to your project's Build Phases ➜ Link Binary With Libraries
Run your project (Cmd+R)<

Android

Open up android/app/src/main/java/[...]/MainApplication.java

Add import com.reactlibrary.securekeystore.RNSecureKeyStorePackage; to the imports at the top of the file
Add new RNSecureKeyStorePackage() to the list returned by the getPackages() method

Append the following lines to android/settings.gradle:

include ':react-native-secure-key-store'
project(':react-native-secure-key-store').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-secure-key-store/android')

Insert the following lines inside the dependencies block in android/app/build.gradle:
```
compile project(':react-native-secure-key-store')
```

Usage

import RNSecureKeyStore, {ACCESSIBLE} from "react-native-secure-key-store";

// For storing key
RNSecureKeyStore.set("key1", "value1", {accessible: ACCESSIBLE.ALWAYS_THIS_DEVICE_ONLY})
	.then((res) => {
		console.log(res);
	}, (err) => {
		console.log(err);
	});

// For retrieving key
RNSecureKeyStore.get("key1")
	.then((res) => {
		console.log(res);
	}, (err) => {
		console.log(err);
	});

// For removing key
RNSecureKeyStore.remove("key1")
	.then((res) => {
		console.log(res);
	}, (err) => {
		console.log(err);
	});

For demo app, checkout example directory.

Options

Key	Platform	Description	Default
`accessible`	iOS only	This dictates when a keychain item is accessible, see possible values in `Keychain.ACCESSIBLE`.	`Keychain.ACCESSIBLE.WHEN_UNLOCKED`

`Keychain.ACCESSIBLE` enum

Key	Description
`WHEN_UNLOCKED`	The data in the keychain item can be accessed only while the device is unlocked by the user.
`AFTER_FIRST_UNLOCK`	The data in the keychain item cannot be accessed after a restart until the device has been unlocked once by the user.
`ALWAYS`	The data in the keychain item can always be accessed regardless of whether the device is locked.
`WHEN_PASSCODE_SET_THIS_DEVICE_ONLY`	The data in the keychain can only be accessed when the device is unlocked. Only available if a passcode is set on the device. Items with this attribute never migrate to a new device.
`WHEN_UNLOCKED_THIS_DEVICE_ONLY`	The data in the keychain item can be accessed only while the device is unlocked by the user. Items with this attribute do not migrate to a new device.
`AFTER_FIRST_UNLOCK_THIS_DEVICE_ONLY`	The data in the keychain item cannot be accessed after a restart until the device has been unlocked once by the user. Items with this attribute never migrate to a new device.
`ALWAYS_THIS_DEVICE_ONLY`	The data in the keychain item can always be accessed regardless of whether the device is locked. Items with this attribute never migrate to a new device.

Handle App uninstalls (iOS only)

By default, this library resets the device's Keychain when it detects the app has been uninstalled.

If you don't want this to occur, you can disable this behavior at any given time by doing:

RNSecureKeyStore.setResetOnAppUninstallTo(false)

Testing

For Testing using Jest, add RNSecureKeyStoreMock implementation under your test/mocks folder. This mock implementation makes easy for you to make testing that dependes on react-native-secure-key-store
