How many different keys are there with the Caesar cipher? Explain.

Answer 1

There are 25 different keys with the Caesar cipher. This is because the Caesar cipher works by shifting each letter in the alphabet by a certain number of positions. Since there are 26 letters in the standard English alphabet, there are 25 possible shifts that can be made (1 through 25). Each shift represents a different key, so there are 25 different keys in total for the Caesar cipher.
