Vigenère Cipher Encryption

This project contains a Python implementation of the Vigenère Cipher encryption algorithm. The Vigenère cipher is a method of encrypting alphabetic text by using a series of Caesar ciphers based on the letters of a keyword.

Code Overview

The code includes the following main components:

• Vigenère Encryption Algorithm: Encrypts plaintext using a keyword.
• SubProcess: A utility to handle encryption and decryption operations.

Features

• Encrypts a given plaintext using the Vigenère cipher.
• Decrypts a ciphertext using the same keyword.
• Implements the core logic of the Vigenère cipher.

How to Use

• Run the script with a plaintext and a keyword to encrypt the message.
• Use the same keyword to decrypt the ciphertext back to the original message.
