Affine Cipher

Overview

• Created a Python program that implements the affine cipher for encryption and decryption, as well as a tool to determine the key shift from a given ciphertext.
• Built command-line argument support for input and output files, operation type (encrypt, decrypt, or shift detection), and relevant keys.
• Applied modular arithmetic, cryptographic principles, and file I/O in Python.
• Refined skills in argument parsing, user input validation, and structuring maintainable command-line applications.
