In this tutorial, we’re going back in time. We’re going to see how to implement the Caesar cipher in Python. The Caesar cipher, also known as the Caesar shift or Caesar's code, is one of the oldest and simplest encryption techniques in the history of cryptography. The Caesar cipher ...

The algorithm is simple and involves substituting a letter with another from later in the alphabet. The key is how many spots in the alphabet you must move to find the original letter or set of letters in a word to decrypt the message. The key was three in this version of Caesar cipher...
Julius Caesar invented another early cipher -- one that was very simple and yet confounded his enemies. He created enciphered messages by shifting the order of the alphabet by a certain number of letters. For example, if you were to shift the English alphabet down three places, the letter ...
The Python modulo operator can be used to create ciphers. A cipher is a type of algorithm for performing encryption and decryption on an input, usually text. In this section, you’ll look at two ciphers, the Caesar cipher and the Vigenère cipher. ...
The Caesar cipher was once state-of-the-art in keeping messages secret by substituting one letter for another. It is now reduced to a cryptogram game that my 96-year-old grandmother tackles daily. We’ve come a long way since Caesar ciphers were state-of-the-art, but ...
A Polybius square is a form of code. A code substitutes other characters for letters, in this example, digits. Ciphers replace letters with other letters. Caesar's Cipher Julius Caesar gave his name to Caesar's Cipher. This uses an offset — or "rotation" — to select a letter a set...
