Ghost Writer: Key Logger and Screen Capture Utility

This C# application, Ghost Writer, is a utility that captures keyboard input and takes screenshots whenever certain keys are pressed. It logs the captured data into a text file and stores screenshots in a designated directory.

Features

• Keyboard Logging: Captures and records keystrokes into a text file.
• Shift/Caps Lock Tracking: Detects and adjusts input based on the state of the Shift and Caps Lock keys.
• Screen Capture: Takes a screenshot whenever the Enter or Tab key is pressed.
• Exit Command: Allows the user to terminate the program by pressing Shift + Esc.

Requirements

• Operating System: Windows (due to the use of Windows APIs for keyboard hooking)
• Framework: .NET Framework 4.7.2+ or .NET Core 3.1+

Setup

1. Compile and Build:

   • Use Visual Studio or another C# IDE to build the solution.
   • Ensure you have the necessary dependencies for System.Windows.Forms and System.Drawing.

2. Run the Program:

   • After building, run the executable file from the command line or directly from the IDE.

Usage

1. Log Files:

   • A text file named Text_Data.txt is created or appended in the current directory.
   • Each recorded keystroke is stored in this file.

2. Screenshot Storage:

   • A folder named Image_Data is created in the current directory.
   • Screenshots are saved as JPEG images with timestamps.

3. Exit the Program:

   • Press Shift + Esc to terminate the application safely.

Example Output

1. Keystroke Logging:

   • All captured keystrokes are saved in Text_Data.txt in real-time.
   • The state of the Shift and Caps Lock keys is tracked, allowing accurate representation of upper/lowercase letters and special characters.

2. Screenshots:

   • Saved in the Image_Data folder with filenames in the format MM-DD-YYYY_HH-MM-SS.jpg.

Notes

• Security & Ethical Use: This tool captures sensitive information. Use it only in a legal and ethical manner, with the explicit consent of the users being monitored.
• Performance: While running, the application hooks into low-level keyboard events, which might be flagged as suspicious by antivirus software.

Dependencies

• System.Windows.Forms: For user interface interactions.
• System.Drawing: For image creation and processing.
• Windows APIs: Used for low-level keyboard hooking and monitoring.

Limitations

• This program is intended for Windows environments only.
• It may require elevated permissions to set keyboard hooks and create files in certain directories.
