In cryptography, the Caesar cipher (English: Caesar cipher), or Caesar encryption, Caesar transform, and transform encryption, is one of the simplest and most widely known cryptographic techniques. It is a technique of replacing cryptography, in which all letters in the plaintext are shifted backwards (or forwards) on the alphabet and replaced by a fixed number of redact. For example, when the offset is 3, all the letters A will be replaced with D,b to E, and so on. This encryption method was named after the Roman Republic of Caesar, who used this method to contact his generals.

Encryption formula: En (x) = (x + N) mod 26

Decryption formula: Dn (x) = (x-n) mod 26
