Multi-Layer Cryptography Application – Python Tkinter GUI

A desktop application built with Python and Tkinter that provides multi-layer encryption and decryption using a sequence of classical cryptographic algorithms, including:

- Caesar Cipher

- Vigenère Cipher

- Playfair Cipher

- Monoalphabetic Cipher

- Rail Fence Cipher

- Row-Column Transposition

- Simplified DES

- AES

The application allows manual control of the encryption order, individual processing for each algorithm, and key customization for maximum flexibility.
