# Secure Session Serinus provides a secure session hook that can be used to secure your session data. The secure session hook uses the [`secure_session`](https://pub.dev/package/secure_session) package to encrypt and decrypt session data. ```dart import 'package:serinus/serinus.dart'; Future main() async { final app = await serinus.createApplication( entrypoint: AppModule(), host: '0.0.0.0', port: 3000 ); app.use(SecureSessionHook( options: [ SessionOptions( secret: 'a' * 16, salt: 'b' * 16 ) ] )); await app.serve(); } ``` The `SecureSessionHook` constructor takes a list of `SessionOptions` objects. The hook also provides the instance of the `SecureSession` class that can be accessed through the `use` method of the request context. ```dart class AppController extends Controller { /// The constructor of the [AppController] class. AppController({super.path = '/'}) { on(Route.get(), _handleEcho); } Future> _handleEcho(RequestContext context) async { context.use().write('value', 'key'); // The key must be available in the session options. return {'message': 'Hello, World!'}; } } ```
