![]() ![]() We use the following steps to implement the program for the Caesar Cipher technique: We can mathematically represent the encryption of a letter by a shift n in the following way:Įncryption phase with shift n = E n (x) = (x+n)mod 26ĭecryption phase with shift n = D n (x) = (x-n)mod 26 Examples The integer value is known as shift, which indicates the number of positions each letter of the text has been moved down. Based on his name, this technique was named as Caesar Cipher technique.Īn integer value is required to cipher a given text. ![]() ![]() Julius Caesar was the first one who used it for communicating with his officials. In this technique, each letter of the given text is replaced by a letter of some fixed number of positions down the alphabet.įor example, with a shift of 1, X would be replaced by Y, Y would become Z, and so on. It is one of the simplest and most used encryption techniques. Next → ← prev Caesar Cipher Program in Java ![]()
