A Flutter plugin to store data in secure storage:
- Keychain is used for iOS
- AES encryption is used for Android. AES secret key is encrypted with RSA and RSA key is stored in KeyStore
- With V5.0.0 we can use EncryptedSharedPreferences on Android by enabling it in the Android Options like so:
AndroidOptions _getAndroidOptions() => const AndroidOptions(
encryptedSharedPreferences: true,
);
import 'package:flutter_secure_storage/flutter_secure_storage.dart';
// Create storage
final storage = new FlutterSecureStorage();
// Read value
String value = await storage.read(key: key);
// Read all values
Map<String, String> allValues = await storage.readAll();
// Delete value
await storage.delete(key: key);
// Delete all
await storage.deleteAll();
// Write value
await storage.write(key: key, value: value);
