Working / Workflow 💪⚒

🔑 Password Management

• Goto Create Password page.
• Add your credentials and password.
• The app generates an encryption key using NDK for added security.
• Your password is encrypted and securely saved in the database.
• When you view the password, it is decrypted in real-time and displayed to you.
• The encryption/decryption key is stored in C++ code using NDK, ensuring enhanced security.

🎨 Theme Customization

• All colors are accessed using attributes (e.g., ?attr/myPrimaryColor) rather than being hardcoded.
• Depending on the selected theme, colors change dynamically, providing a multi-theme experience.
• The selected theme is saved in Shared Preferences, ensuring it persists across sessions.

🌍 Multi-Language Support

• All app text is stored in string resource files instead of being hardcoded.
• Text is accessed using references like @string/click.
• When a language is selected, the app updates all text dynamically.
• The selected language is stored in Shared Preferences for consistent localization.

📂 Backup & Restore

• The app’s database is securely stored in the app directory.
• Backup Process:
  • The app creates a copy of the database and saves it in the Downloads directory with a timestamp.
• Restore Process:
  • The selected backup file is copied back to the app’s directory, restoring all data seamlessly.

📑 PDF/CSV Export

• All stored passwords are retrieved and organized into a list.
• PDF Export:
  • Passwords are written onto canvas pages, styled, and converted into a PDF file.
  • The PDF is saved in the user’s Downloads directory.
• CSV Export:
  • Passwords are formatted into rows and columns and saved as a CSV file in the Downloads directory.

🔐 Passkey, PIN, and Biometric Lock

• Unlock the app using either a Passkey, PIN, or Biometric Authentication.
• The Passkey acts as a master password and is always active.
• Only one of PIN or Biometric Lock is active at a time.
• Credentials like PINs and passwords are securely stored in Shared Preferences, protected using AES encryption.
• This ensures robust security and keeps your data safe from unauthorized access.

Technologies Used 👩‍💻⚙👨‍💻

• mvvm

  • MVVM stands for Model-View-ViewModel, which is a software architectural pattern commonly used in modern UI frameworks, including Android development. In MVVM, the application is divided into three main components:

    1. Model: Represents the data and business logic of the application.
    2. View: Represents the UI components visible to the user.
    3. ViewModel: Acts as an intermediary between the View and the Model, providing data and behavior to the View while
    4. abstracting away the underlying business logic.

  • MVVM promotes separation of concerns, making it easier to maintain and test the codebase. It also facilitates reusability of components and promotes a more modular architecture.

• LiveData

  • LiveData is a lifecycle-aware data holder class in Android Jetpack. It ensures that your UI observes only the latest data changes and reacts accordingly, reducing the risk of memory leaks. LiveData automatically updates the UI when the underlying data changes, making it an essential component in the MVVM architecture.
  • It works seamlessly with ViewModel, helping to keep the UI and business logic separate.

• NDK (Native Development Kit)

  • The Android Native Development Kit (NDK) is a toolset that allows developers to write portions of their app using native code languages like C and C++. It provides performance advantages by leveraging native libraries and components for computationally intensive tasks.
  • The NDK is particularly useful for tasks like game development, cryptography, and real-time audio or video processing.

• Room Database

  • Room is a part of the Android Jetpack suite and provides a robust abstraction layer over SQLite to help developers build a database with minimal boilerplate code.
  • It ensures compile-time verification of SQL queries, supports LiveData for observing database changes, and integrates seamlessly with Kotlin Coroutines for asynchronous data operations.

• AES Encryption

  • AES (Advanced Encryption Standard) is a secure and widely used encryption algorithm. In Android development, AES encryption can be used to secure sensitive data like passwords, tokens, or any confidential user information.
