How to Build a Caesar Crypto Module in Python

The Caesar Cipher module is a foundational educational topic in cybersecurity that introduces the core principles of encryption, data transformation, and symmetric keys. Named after Julius Caesar, who used it to protect his military communications, it is one of the earliest and simplest forms of a substitution cipher. How the Caesar Cipher Works

The module explains cryptography by transforming readable text (plaintext) into an unreadable format (ciphertext). It does this by shifting every letter in the message by a fixed number of positions down the alphabet. What a Caesar Cipher Can Teach Students About Cryptography
