Web17 de jul. de 2024 · A simple example of a substitution cipher is called the Caesar cipher, sometimes called a shift cipher. In this approach, each letter is replaced with a letter some fixed number of positions later in the alphabet. For example, if we use a shift of 3, then the letter A would be replaced with D, the letter 3 positions later in the alphabet.
