D-Encryptor

D-Encryptor is a Python-based GUI tool for message encryption and decryption using cryptographic techniques such as Caesar Cipher, Vigenère Cipher, and Columnar Transposition Cipher. Features

Encrypt and decrypt text using:

    Caesar Cipher

    Vigenère Cipher (with a fixed key: tractor)

    Row-Column Transposition Cipher

GUI built with tkinter

Displays:

    ASCII conversions

    Matrix manipulations

    Detailed intermediate steps in the console

Requirements

Python 3.x

Python packages:

    numpy

    tkinter (usually included with Python)

How to Run

Clone this repository:

git clone https://github.com/yourusername/D-Encryptor.git
cd D-Encryptor

Run the script:

    python your_script_name.py

The GUI will open. Enter your message, choose an encryption method, and click Encrypt or Decrypt.

Note: The GUI currently contains placeholder button functions (ButtonTest). You will need to link them to the actual encryption functions like CaesarCipher, VigenereCipher, or RowColumnTCipher. Supported Algorithms Caesar Cipher

A shift-based encryption method where each character is shifted by a fixed number of positions. Key used: 6 Vigenère Cipher

A polyalphabetic substitution cipher using a repeating key. Key used: "tractor" Row-Column Transposition Cipher

Reorders characters into a matrix and sorts the columns based on a key. Key used: [5, 2, 6, 1] Example Usage (Command Line)

n = message() ascii_array = Text2ASCII(n) encrypted = CaesarCipher(ascii_array) OutputMessage(encrypted)

To Do

Link encryption and decryption logic to the GUI buttons

Add user-defined key input support for Caesar and Vigenère ciphers

Improve error handling and input validation

Enhance the GUI layout and usability
