AES Encryption/Decryption Program (WIP)

This program provides a user-friendly interface for encrypting and decrypting data using the Advanced Encryption Standard (AES-128 specfically) algorithm. It combines a C-based encryption/decryption core with a Python-based graphical user interface (GUI) for ease of use.

Getting Started

Follow the steps below to set up and use the AES encryption/decryption program.

Prerequisites

Before using the program, make sure you have the following prerequisites installed:

• Python (for the GUI)
• GCC (for compiling the C code)

Installation

1. Clone or download this GitHub repository to your local machine.

   git clone https://github.com/yourusername/your-repository.git
   

Procedure For Using the Program:

1. Compile the C code by navigating to the directory containing the C source files and running the following command:

   gcc -o main main.c aes_encryption.c aes_utils.c
   

2. Run the Python script for the program by executing the following command in your terminal:

   python EncryptDecrypt.py

   a. The GUI window should appear, allowing you to perform the following actions:

   • Enter the 32-character encryption key (in hexadecimal format).
   • Enter the input file name.
   • Choose between encryption and decryption modes.

   b. Follow the on-screen instructions to proceed with encryption or decryption.

   c. After running the program with valid inputs, it will perform encryption or decryption as selected and display a success message or an error message if something goes wrong.
