Image Encryption Tool : Pixel Manipulation

This tool provides a simple yet effective way to encrypt and decrypt images using pixel manipulation techniques. It allows users to securely alter image data using a key-based encryption method.

Features

• Encryption: Encrypt images by scrambling pixel positions and applying mathematical operations.
• Decryption: Decrypt previously encrypted images to restore them to their original state.
• Command-Line Interface: Easy-to-use CLI for interacting with the tool.

How It Works

Encryption Process

1. Load Image: Load the input image.
2. Pixel Manipulation: Randomly swap pixel positions and apply mathematical operations.
3. Save Encrypted Image: Save the modified image to a new file.

Decryption Process

1. Load Encrypted Image: Load the previously encrypted image.
2. Reverse Pixel Manipulation: Undo the pixel swaps and mathematical operations.
3. Save Decrypted Image: Save the restored image to a new file.

Installation

1. Clone the Repository:

   git clone https://github.com/kur1an/SCT_CS_2.git
   cd SCT_CS_2

2. Install Dependencies: Make sure you have Python installed on your system. Additionally, install the required libraries using pip:

   pip install pillow

Usage

1. Encrypt an Image:

   • Run the script: python image_tool.py
   • Choose the encryption mode.
   • Provide the input image path.
   • Specify the output path for the encrypted image.
   • Enter the encryption key.

2. Decrypt an Image:

   • Run the script: python image_tool.py
   • Choose the decryption mode.
   • Provide the input image path (encrypted image).
   • Specify the output path for the decrypted image.
   • Enter the decryption key.

Example

Encrypt an image:

python image_tool.py
Choose mode (encrypt/decrypt)e/d: e
Enter the input image path: input_image.jpg
Enter the output image path: encrypted_image.jpg
Enter the encryption key: 12345

Decrypt an image:

python image_encryption_tool.py
Choose mode (encrypt/decrypt)e/d: d
Enter the input image path: encrypted_image.jpg
Enter the output image path: decrypted_image.jpg
Enter the decryption key: 12345
