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. ...
Like caesar_cipher(), vigenere_cipher() iterates over each letter of the input text to encrypt or decrypt it: Python for i, char in enumerate(text): current_key = key[i % len(key)] In the above code, you can see the function’s first use of the modulo operator: Python curren...
First we take the whole alphabet, alp = 'a, b, c, d, ...), etc., then, we get the user input, then we find these letters in alp, and +1 should go to each letter , i.e.
This version asks users to use a mouse to trace certain shapes found in photographs. ©2008 HowStuffWorks CAPTCHA technology has its foundation in an experiment called the Turing Test. Alan Turing, sometimes called the father of modern computing, proposed the test as a way to examine ...

Learn how to make a cipher wheel using thick paper, pin, protractor, eraser and pencil. Use our step by step craft activity guide to get the idea.
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, in which case you would substitute the letter D for letter A, H for E, and so on. ...
To ensure secure file access, data encryption has evolved significantly from ancient techniques like the Caesar Cipher to sophisticated algorithms that are in use today. Modern encryption makes use of complex algorithms that shuffle file contents, with decryption relying on a provided key. ...
