WebFound in almost every encryption algorithm, the key determines how the data is encrypted. In the Caesar cipher, the key is a number from 0 to 25, because there are 26 letters in the alphabet. This means that for any given message, there are 26 different ways we can encrpyt the message. For each letter, the key determines which letter is ...
