🔒 Complex Image Encryptor

A simple Python GUI tool that makes your images completely unrecognizable by using pixel-level encryption: it shuffles pixel positions and XORs the pixel values with your secret Key and Seed.

---

✨ Features

• Strong scrambling: Pixel values are XOR-ed with your secret key.
• Position shuffle: Pixels are shuffled using a repeatable random seed.
• Fully reversible: Using the same Key + Seed decrypts the image exactly.
• Simple GUI: Built with CustomTkinter.
• Supports PNG, JPG.

🔑 How it works

• Encrypt: Each pixel (R, G, B) is XOR-ed with your Key → pixel array is shuffled with your Seed.

• Decrypt: The shuffle is reversed using the same Seed → pixel values are XOR-ed again with the same Key → original image is restored.

• Without your Key + Seed, it’s practically impossible to recover the original.

🧩How to Use

• 1️⃣ Install requirements
• 2️⃣ Run the app
• 3️⃣ Encrypt an image
  • Click Load Image.
  • Enter your Key (any integer).
  • Enter your Seed (any integer).
  • Click Encrypt Image and save the scrambled file.
• 4️⃣ Decrypt an image
  • Load the encrypted image.
  • Enter the same Key & Seed.
  • Click Decrypt Image — the original image will be restored and saved.

🔑 Remember:

Key & Seed must match to decrypt correctly.

Without them, the scrambled image is unreadable!
