Crypt is a lightweight mobile application for on-device file encryption and decryption.
It is built with Xamarin and relies on AES-256 together with PBKDF2 for secure key handling.
- 🔐 Encrypts and decrypts files of any format
- 🛡️ Uses AES-256 with PBKDF2-derived keys
- 📁 Works directly with files stored on the device
- 📳 Clean, minimal interface
- Open the project in Visual Studio 2022
- Ensure Xamarin.Forms (or Xamarin.Android) dependencies are installed
- Deploy the app to an Android emulator or a physical Android device
Crypt is designed as a quick, on-the-go encryption tool that works offline and requires no internet connection or third-party services—ideal for personal file security.
