## Caesar Cipher Decryption Tool

This tool allows you to encrypt and decrypt text using a simple offset algorithm - known as Caesar cipher. When you are using 13 as the key, the result is similar to an rot13 encryption. When you use "guess" as the key, the algorithm tries to find the right key and decrypts the string by an educated guess. If you want some in-depth knowledge about encryption, I highly recommend to read this introduction book
