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 ...
currently working on an assignment that requires me to write a script that inputs a line of encrypted text and a distance value and outputs plaintext using a Caesar cipher. I've done that and it works great for lower case letters however it does not work for capital letters or symbols (...

A classic example is the Caesar cipher, in which each letter is shifted to a certain number of positions in the alphabet. In a more complex substitution cipher, such as the monoalphabetic cipher, each letter of the plaintext is replaced with a unique letter from a scrambled version of the ...
How to Crack the Caesar cipher in Python Finally, having explored the intriguing process of cracking the Affine Cipher with Python, you might be eager to delve further into the cryptographic realm. Our Cryptography with Python eBook is tailored for enthusiasts like you, offering a deeper dive int...
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...
To decrypt this message, you have to shift them back by the same number of characters: public static void main(String[] args) { String encrypted = caesarCipher("message", 3); String decrypted = caesarCipher(encrypted, -3); System.out.println(encrypted); // phvvdjh System.out.printl...
