#### iOS

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

#### Android

1. 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
2. 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')
`
3. Insert the following lines inside the dependencies block in android/app/build.gradle:
`
compile project(':react-native-secure-key-store')
`

Usage

`javascript
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 |

$3

| 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:

`js
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
