WebIn cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a … WebBased on a shift key, each letter in the alphabet is replaced by the new shifted letter. The message which is enciphered by replacing the corresponding new letter is called plaintext, and the new message which is produced by the substitution is called ciphertext.
