Caesar Cipher Encryption/Decryption Tool

Description

This project implements a Caesar cipher encryption and decryption tool in Python. The Caesar cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Features

• Encryption: Encode a message using a specified shift value.
• Decryption: Decode a message using a specified shift value.
• Interactive CLI: Provides a command-line interface to input text, choose the operation (encode/decode), and specify the shift amount.

Usage

• Type 'encode' to encrypt a message.
• Type 'decode' to decrypt a message.
• Enter the text you want to encode or decode.
• Provide the shift amount as an integer.
• The script will display the result and prompt you to either continue or exit.

Requirements

• Python 3.x
