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...

Cryptographers began to search for new ways to encipher messages. The Caesar Shift was too easy to crack -- given enough time and patience, almost anyone could uncover the plaintext behind the ciphered text. Kings and priests hired scholars to come up with new ways to send secret messages....
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. ...
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 ...
After the data is converted from plaintext to ciphertext, it can be decoded only through the use of the proper key. This key might be the same one used for encoding the data or a different one, depending on the type of algorithm -- symmetric or asymmetric. If it's a different key,...
We notice that, rather than hiding, the functionality of a tweak is no more than an index to the block cipher in most of use-cases, and are even assumed to be under attacker’s full control in some cryptanalytic settings. Hence, the required level of “protection” for a tweak is ...
