You can see the Caesar cipher, that is the output as shown in the following image − Explanation # Encrypt lowercase characters in plain text # Encrypt uppercase characters in plain text The program implementation of Caesar cipher algorithm is as follows − The following diagram depicts the working of Caesar cipher algorithm implementation −
It is simple type of substitution cipher.Įach letter of plain text is replaced by a letter with some fixed number of positions down with alphabet. The algorithm of Caesar cipher holds the following features −Ĭaesar Cipher Technique is the simple and easy method of encryption technique. This chapter talks about Caesar cipher in detail. In the last chapter, we have dealt with reverse cipher.
