A Flutter plugin to store critical 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
Note KeyStore was introduced in Android 4.3 (API level 18). The plugin wouldn't work for earlier versions.
import 'package:impiger_securestroage/impiger_securestroage.dart'; // Create storage final _storage = new StoreCriticalData(); //write String value _storage.writeString(key: “key”, value: “value”); // Read String value String value = _storage.readString(key: "key"); //write Double value _storage.writeDouble(key: “key”, value: “value”); //Read Double value final double value = _storage.readDoubleNew(key: "key");
