dart secure

🛡️ Dart Secure 🛡️ #







A Dart package that provides functionalities to enhance user authentication and data encryption in Dart applications. This package integrates multiple cybersecurity practices to secure sensitive user data and interactions. The package includes the following features:
Features #
🔐 Temporary Lock User
🔑 User Authentication Monitoring
✋ Biometric User Authentication
🔒 InApp Data Encryption
🔓 InApp Data Decryption
#️⃣ Hashing Data
#
📖 Getting Started #
To use this package, add dart_secure as a dependency in your pubspec.yaml file:
dependencies:
dart_secure: ^(check current version)

Then import the necessary features in your Dart code:
import 'package:dart_secure/dart_secure.dart';

#
Features #
#
🔐 Temporary Lock User #
You can use the tempLockUser method to lock the user after multiple failed login attempts. This function takes the following parameters:

context (required): The BuildContext of the current screen.
time (optional): The duration in seconds for which the user will be locked. Default is 30 seconds.
afterCountNavigateTo (required): The widget to navigate to after the countdown timer finishes.
lockedPageMessage (optional): The message to display on the locked user page. Default is "You are temporarily locked."

Future<void> lockUser() async {
await tempLockUser(
context,
time: 60, // Lock user for 60 seconds
afterCountNavigateTo: HomeScreen(), // Navigate to HomeScreen after timer finishes
lockedPageMessage: "Your account has been temporarily locked for security reasons.",
);
}
copied to clipboard
Customization
You can customize the appearance of the countdown timer page by modifying the _countdownPage function. This function creates the UI displayed to the user during the lockout period.
Note

The package uses a StreamBuilder to display the countdown timer and navigate to the next page once the timer completes.
The countdown timer can't be bypassed by pressing the back button.

Example
Here's a simple example of how to use the feature:
//Temporary lock the user
void TempLockThisUser() {
// Simulate a failed login attempt
tempLockUser(context, afterCountNavigateTo: LoginPage());
}

#
🔑 User Authentication Monitoring for Firebase #
The userAuthMonitor feature allows you to monitor user authentication using Firebase Auth and display different pages based on the user's authentication state. This can be particularly useful for managing user access and providing a seamless experience for authenticated and unauthenticated users.
dependencies:
flutter:
sdk: flutter
firebase_auth: ^<latest_version>
copied to clipboard
Usage
To get started with user authentication monitoring, you can use the userAuthMonitor function provided by the dart_secure package. This function takes various parameters to customize the behavior based on your requirements:

authenticatedUserPage: The page/widget to be shown when the user is authenticated.
unAuthenticatedUserPage: The page/widget to be shown when the user is not authenticated.
adminUID: The UID of the admin user (optional). If provided, a specific admin page can be shown.
adminPage: The page/widget to be shown if the authenticated user's UID matches the adminUID.
blockUID: A list of UIDs representing blocked users (optional). Blocked users will see the userBlockedPage.
userBlockedPage: The page/widget to be shown for blocked users.

Here's an example of how you can use this feature:
import 'package:flutter/material.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:dart_secure/dart_secure.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: userAuthMonitor(
authenticatedUserPage: HomePage(),
unAuthenticatedUserPage: LoginPage(),
adminUID: 'your_admin_uid_here',
adminPage: AdminPage(),
blockUID: ['blocked_user_uid_1', 'blocked_user_uid_2'],
userBlockedPage: UserBlockedPage(),
),
);
}
}

// Define your pages/widgets here (HomePage, LoginPage, AdminPage, UserBlockedPage).

This example demonstrates how to create a seamless user authentication experience with custom pages for different user states. Make sure to replace placeholder values with your actual implementation.
#
This new section provides an explanation of the new feature, its installation, usage, and a sample code snippet for integrating it into your Flutter application. Make sure to adjust the placeholders and example code to fit your actual implementation and requirements.
#
🧑✋ Biometric User Authentication #
Note that this plugin works with both Touch ID and Face ID. However, to use Face ID, you need to add the following to your Info.plist file:
iOS Integration
<key>NSFaceIDUsageDescription</key>
<string>Why is my app authenticating using Face ID?</string>
copied to clipboard
Android Integration

The plugin will build and run on SDK 16+, but isDeviceSupported() will return false before SDK 23 (Android 6.0).

Activity Changes
local_auth requires the use of a FragmentActivity instead of an Activity. To update your application:
If you are using FlutterActivity directly, change it to FlutterFragmentActivity in your AndroidManifest.xml.
If you are using a custom activity, update your MainActivity.java or MainActivity.kt to inherit from FlutterFragmentActivity.
Permissions
Update your project's AndroidManifest.xml file to include the USE_BIOMETRIC permission:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.app">
<uses-permission android:name="android.permission.USE_BIOMETRIC"/>
</manifest>
copied to clipboard
The biometricAuth feature offers a secure way to implement biometric user authentication in your app. It supports various biometric authentication methods on the device. Example usage:
getBiometric() async {
var authStatus = await biometricAuth();
if (authStatus == AuthenticationStatus.successful) {
print("Authentication successful, continue");
} else {
print("Authentication unsuccessful, try again");
}
}

#
🔒 In-App Encryption #
The InAppEncryption feature allows you to encrypt sensitive data within your app using a specified encryption key:
String encryptedAddress = inAppEncrypt(text: "User's Address", key: "MyUsersAddress");
copied to clipboard
#
#️⃣ Hash Encryption #
The hashEncryption feature securely hashes data, useful for scenarios like password storage:
String encryptedAddress = hashEncrypt(text: "User's Address");
copied to clipboard
#
🔓 In-App Decryption #
The InAppDecryption feature lets you decrypt encrypted data within your app using the appropriate decryption key:
String encryptedAddress = InAppDecryption(cipher: "######################", key: "MyUsersAddress");
