WebThe action of a Caesar cipher is to replace each plaintext letter with a different one a fixed number of places down the alphabet. The cipher illustrated here uses a left shift of three, so that (for example) each occurrence of E in the plaintext becomes B in the ciphertext. WebA cipher is a secret code, usually one that's created using a mathematical algorithm. Sometimes the message written in code is itself called a cipher. SKIP TO CONTENT. ...
