Message Encryption and Decryption

This Python script implements a simple GUI-based application using the Tkinter library for message encryption and decryption using the Vigenère cipher. The Vigenère cipher is a method of encrypting alphabetic text by using a simple form of polyalphabetic substitution.

Features

• User-friendly Interface: The graphical user interface provides a straightforward way for users to input information and interact with the application.

• Encryption and Decryption: The application allows users to encrypt and decrypt messages using the Vigenère cipher.

• Input Validation: The script includes basic input validation to handle empty fields or incorrect input formats.

Requirements

The following Python modules are used in the script:

• Tkinter: For building the GUI.
• base64: For encoding and decoding messages.
• random, time, datetime: For various time-related functionalities.

Usage

1. Run the Script: Execute the script using the following command:

   python one.py 

or

   python3 one.py 

2. Enter Information:

   • Provide a name in the "Name" field.
   • Enter the message in the "Message" field.
   • Input the encryption or decryption key in the "KEY" field.
   • Choose the mode ("e" for encrypt, "d" for decrypt).
   • Click the "Show Message" button to view the result.

3. Reset and Exit:

   • Use the "Reset" button to clear all fields.
   • Click "Exit" to close the application.

Note

• The application uses the Vigenère cipher for encryption and decryption.
• Make sure to provide valid inputs for a seamless experience.
• For educational purposes only.

Feel free to customize and extend the script according to your needs.
