The Caesar Cipher algorithm is the simple and easy approach of encryption technique. It is a simple type of substitution cipher in which the alphabets are moved by using a selected number of areas to create the encoded message. An A can be encoded as a C, M as an O, a Z as an B,...

In cryptography, a Caesar cipher, also known as a 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 letter some...

The Caesar cipher is a technique in which an encryption algorithm is used to change some text for gaining integrity, confidentiality, or security of a message. In cryptography there are many algorithms that are used to achieve the same, but Caesar cipher is the earliest and easiest algorithm us...
