AES CTR Encrypt/Decrypt GUI GTK+

This is an AES encryption and decryption program in CTR (Counter Mode) with a graphical user interface using GTK+ 3. The program allows users to input data, encrypt, decrypt, and display results (plaintext, nonce, ciphertext) on the interface.

Features

• Encrypt data input from the interface with 128-bit (32 HEX characters), 192-bit (48 HEX characters), or 256-bit (64 HEX characters) keys.
• Decrypt data from files containing nonce (8 bytes) and ciphertext.
• Display plaintext, nonce, and ciphertext in HEX format on the interface.
• Save encryption results to encrypted.bin file and decryption results to decrypted.txt file.
• Support simple interface with Encrypt, Decrypt, and Clear buttons.

System Requirements

• Linux: GCC, GTK+ 3
• Windows: MinGW-w64, GTK+ 3

Setting up Development Environment on Linux (Ubuntu/Debian)

### 1. Install compiler tools and GTK libraries

sudo apt update
sudo apt install build-essential libgtk-3-dev

### 2. Compile the program 
make

### 3. Run the program 
./aes_ctr_gtk

Setting up Development Environment on Windows

1. Install MinGW-w64 and GTK+ 3

• MinGW-w64: Download and install MinGW-w64 from MinGW-w64.
• GTK+ 3: Download GTK+ 3 from MSYS2. After installing MSYS2, open the MSYS2 terminal and run the following commands to install GTK+ 3:

  pacman -S mingw-w64-x86_64-gtk3

2. Configure Environment Variables

• Add the path to the GTK+ 3 bin directory (e.g., C:\msys64\mingw64\bin) to the PATH environment variable.

3. Compile the Program

• Open MSYS2 or MinGW-w64 terminal and navigate to the directory containing the source code.
• Run the following command to compile the program:

  make

  Or if not using Makefile, you can compile directly with the command:

  gcc -o aes_ctr_gtk aes_ctr_gtk.c aes.c -I<path_to_gtk_include> -L<path_to_gtk_lib> -lgtk-3 -lgobject-2.0 -lglib-2.0 -lgdk-3

  Replace <path_to_gtk_include> and <path_to_gtk_lib> with the corresponding paths to the include and lib directories of GTK+ 3.

4. Run the Program

• After successful compilation, run the program with the command:

  ./aes_ctr_gtk.exe

Notes

• Ensure that all necessary GTK+ 3 libraries are in the PATH so the program can run without missing library errors.
