Ceasar was a Roman politician and military general who played a critical role in the rise of the Roman Empire. Ceasar used this method of encryption for sending messages to his soldiers and generals. This is the reason for calling this method as Ceasar cipher. In this method, we replace each alphabet in the plaintext by another alphabet. The replacing alphabet is some fixed number of steps to the left or right of original alphabet in the sequence of alphabets.
