WebFeb 2, 2024 · A cipher is a method for encrypting a message, intending to make it less readable. As for the Caesar cipher, it's a substitution cipher that transforms a message by shifting its letters by a given offset. Let's say we want to shift the alphabet by 3, then letter A would be transformed to letter D, B to E, C to F, and so on.
