Image Encryption/Decryption Tool By 4444 & Cp6E

This is a command-line tool written in Python for encrypting and decrypting images using the Advanced Encryption Standard (AES) algorithm. The tool uses the Cryptodome library for AES encryption and the tqdm library for progress bars.

Features

• Encrypts an image file using a user-provided encryption key.
• Decrypts an encrypted image file using the correct encryption key.
• Displays progress bars during encryption and decryption.

Requirements

• Python 3.x Here
• Cryptodome library (pip install pycryptodomex)
• tqdm library (pip install tqdm)
• termcolor library (pip install termcolor)
• rich library (pip install rich)
• or Install All Requirements by Just Running (pip install -r requirements.txt)

Usage

1. Clone the repository to your local machine. by (git clone https://github.com/Insider4444/Image-to-text-to-image)
2. Navigate to the repository directory in your terminal or command prompt.by (cd Image-to-text-to-image)
3. Install the required libraries using the requirements.txt file: pip install -r requirements.txt.
4. Run the Image-Encrypt-4444-v4.py file: python Image-Encrypt-4444-v4.py.

Code Explanation

The following is a brief explanation of the code:

• The get_aes_key() function prompts the user to enter an encryption key, which is used for both encryption and decryption.
• The get_aes_key_bytes(key) function converts the encryption key string to bytes and pads it to the required length for AES encryption.
• The encrypt_image(filename, key) function reads the image data from the specified file, encrypts it using AES encryption with a randomly generated initialization vector (IV), and saves the encrypted data to a text file with the same name as the original image file.
• The decrypt_text(filename, key) function reads the encrypted data from the specified text file, decrypts it using the correct encryption key and IV, and saves the decrypted data to a JPEG file with the same name as the original image file.
• The display_menu() function displays a simple menu for the user to choose between encrypting an image, decrypting an image, or exiting the tool.
• The main() function is the entry point for the program and handles user input to call the appropriate functions.
