+# flutter_secure_storage_aurora
+
+The Aurora implementation of [`flutter_secure_storage`][https://pub.dev/packages/flutter_secure_storage].
+
+## Usage
+
+This package is not an _endorsed_ implementation of `flutter_secure_storage`. 
+Therefore, you have to include `flutter_secure_storage_aurora` alongside `flutter_secure_storage` as dependencies in your `pubspec.yaml` file.
+
+**pubspec.yaml**
+
+```yaml
+dependencies:
+  flutter_secure_storage: ^8.0.0
+  flutter_secure_storage_aurora:
+    path: # path to folder with plugin
+```
+
+***.dart**
+
+```dart
+import 'package:flutter_secure_storage/flutter_secure_storage.dart';
+import 'package:flutter_secure_storage_aurora/flutter_secure_storage_aurora.dart';
+
+// https://pub.dev/packages/encrypt
+// Encrypter(AES(key))
+// secure-random --length 16 --base 16
+// You can generate a secret key based on user data, as an example of a hash pincode
+FlutterSecureStorageAurora.setSecret('5872747ed1ceda363808efb8b2b18b20');
+
+final storage = const FlutterSecureStorage();
+
+const key = 'my_key';
+const data = 'Something secret';
+
+// Write value
+await storage.write(key: key, value: data);
+
+// Read value
+String? value = await storage.read(key: key);
+
+// Read all values
+Map<String, String> allValues = await storage.readAll();
+
+// Delete all
+await storage.deleteAll();
+```
