Project
Name:
Vignere Cipher
Short Description:
This script implements the Vigenère Cipher, a classic polyalphabetic substitution encryption technique.
It accepts a keyword from the user to encode and decode messages. The same keyword must be used to decrypt the output,
making it a lightweight reversible encryption tool. This is a great intro project for learning about ciphers and key-based text transformations.
The script demonstrates:
VigenereCipherclass with methods to encrypt and decrypt alphabetic stringstransform()logic that handles both encryption and decryptionFeel free to enhance it with non-alphabet support, file-based encryption, or use it inside a larger pipeline.
