What is a Caeser shift?

Answer 1

A Caesar shift, also known as a Caesar cipher, is a type of substitution cipher where each letter in the plaintext is shifted a fixed number of places down or up the alphabet. For example, with a shift of three, the letter A would become D, B would become E, and so on. This simple encryption method is named after Julius Caesar, who reportedly used it to communicate with his generals. While easy to implement, it offers minimal security against modern cryptographic analysis.
