![]() Create a loop that will run up to the length of the string.You have to take two inputs one a number and a string which will be a text. ![]() A plaintext or message that we want to encrypt in form of a string.A number, which should be between 0 to 25 in form of an integer.We have to take two inputs to implement caesar cipher in cryptography. By decreasing 3 from each one we can decrypt it. After encryption the value of the first letter F is 6, R is 19, and, so on. Here, the receiver has to put in some more effort. But it’s not necessary we can take any number like 10, 16, or anything. So the receiver can understand quickly which number is to be added to decrypt the message. Here, C is the first letter and it’s on the 3rd number. Now you may be thinking why we took the number 3, we can take any number from 1 to 26. This is what we call caesar cipher encryption. Now we will add 3 to each letter and it will become FRGHGDPQ. In the word CODEDAMN, every letter has a ranking from 1 to 26 and in this case, C has 3, O has 15, D has 4, and so on. So, our text is CODEDAMN and the number is 3. And the number that we have to choose should be a number from 1 to 26 too. As we know every alphabet A to Z has a number from 1 to 26. We’ll need a text and a number to use this method. Let’s understand Caesar cipher in cryptography. Cryptography algorithm for the Caesar cipher We will discuss this logic in the next section. And based on the logic receiver can decrypt it by substituting some letters. Based on some logic we can encrypt our message or text as a sender. He used this method to encrypt his messages using the Caesar cipher encryption method. And after reading the name you might be thinking of Julius Caesar. What is Caesar cipher?Ĭaesar Cipher is one of the simplest methods in cryptography. And if we are talking about security how can we miss cryptography? So, in this article, we will learn about Caesar cipher, one of the cryptographic methods. To complete these activities safely, security is an important part of it. And to support these activities, we have a great infrastructure in the form of the internet. Something like transactions, buying, and selling on online marketplaces. There seem to be some basic activities but apart from these people do various work too. To talking on with friends and family on the internet. We all use the internet daily for basic searching and browsing
