What is Caesar Cipher It is one of the simplest encryption technique in which each character in plain text is replaced by a character some fixed number of positions down to it. One simple and basic method to encrypt a message is using Caesar&x27;s cipher. It is based on the idea of shifting the letters in a message by a certain number of positions along the alphabet, and looping back the the start if the shift moves a letter beyond the end of the alphabet. A Caesar cipher is a simple method of encoding messages. The following is an example. The program takes a single command line argument that defines. C program to perform encryption and decryption . A Caesar Shift cipher is a type of mono-alphabetic substitution cipher where each letter of the plain text is shifted a fixed number of places down the alphabet. The number of positions to shift must first be scanned in from the terminal. The encoding replaces each letter with the 1st to 25th next letter in the alphabet (wrapping Z to A). Write out the entire alphabet in a line. For example, with x 1 , an A becomes a B, a C becomes a D and so on. In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. If we want to see Caesar cipher in mathematical way, then formula to get encrypted letter will be e (x n) mod 26 where, n is the number of positions we need to shift plaintext characters x is the place value of original letter e is the place value of encrypted letter On the other hand, we will use the below formula to decrypt each letter. Oleh karena itu, untuk menghindari hal tersebut, sebelum melakukan enkripsi, algoritma caesar cipher dimodifikasikan terlebih dahulu kemudian dikonversikan kedalam code ASCII. It is a form of substitution cipher, because every letter in the text that you want to encrypt is substituted by another letter. The Caesar cipher is one of the earliest known and simplest ciphers.
