Caesar Cipher CLI

Caesar Cipher in the command-line made in Python. Not secure for real-world use.

Originally made for my school's computer science class homework assignment, but expanded upon to include extra features for fun.

Features

• Classic Caesar Cipher encryption gameplay
• Customisable encryption key
• Linear substitution encryption
• Works for both capital and lowercase letters and numbers (alphanumeric)
• Cycles back if out of bounds (i.e.: 0 - 1 -> 9, 9 + 1 -> 0, A - 1 -> Z, Z + 1 -> A, a - 1 -> z, z + 1 -> a) (Does not work for symbols and other special characters)
• Symmetric decryption by inputting the negative of encryption key into the same function

Usage
