Van Gonography

Abstract

1. Introduction

Hide any type of files inside a image of your choice

2. Objective

Hide 🕵️‍♂️ your files of any type inside a image of your choice using steganography

This project demonstrates how Python can be applied to a real-world Cybersecurity & Ethical Hacking problem.

3. Key Features / Modules

• File Hiding: Hide any type of file within an image of your choice, without altering the image's visual appearance.
• Decoding Capability: Decode hidden files from images.
• Image Comparison: Visualize the difference between two images.
• Detailed Logging: Create a log file that records comprehensive information about the program's execution.
• Command-Line Interface (CLI): Offers a developer-friendly mode with command-line options for more advanced usage.
• User Interface (UI): Provides an intuitive and easy-to-use mode for non-developers.
• Open After Decoding: Automatically open the decoded file after extracting it from the image.
• Cross-Platform: Works on Windows, Linux, and macOS.
• Free and Open-Source: Van Gonography is completely free and open-source, and will always be.
• Encryption: Encrypt the hidden file with a password of your choice (coming soon).
