The Caesar Cipher Tool allows you to encrypt and decrypt text using the classic Caesar Cipher algorithm. When you are selecting a key, such as 13, the tool performs encryption similar to ROT13, shifting each letter by 13 places to obscure the original message. When you use "guess" as the key, the algorithm tries to find the right key and decrypts the string by an educated guess described below.For those eager to deepen their understanding of encryption techniques, I highly recommend exploring this comprehensive introductory book on cryptography.
