⚠️ Current Code Status

The repository contains several placeholder classes, experimental modules, and unimplemented ideas that were created during the active development phase. These include:

• unfinished stubs and concepts;
• prototypes not yet integrated into the main application;
• unused views or services planned for future features.

These components are intentionally retained for development transparency and potential future use. They may be moved or separated into different branches in upcoming updates.

🚀 How to Run

To run the main desktop application:

1. Open the solution file located in the login folder:
   login/CryptorLogin.sln

2. Build and run the project using Visual Studio 2022 (or later) with .NET 8 SDK installed.

3. Ensure all dependencies are restored via NuGet on first build.

🧩 Project Purpose

The WPF application provides a secure interface for encrypting and decrypting documents with support for multiple file types and themes.

The secondary MAUI or library project may be used to extend functionality such as authentication (e.g., Windows Hello) or shared logic across platforms.
