Before attempting to use an Alberti disk cipher read through these requirements. Alberti Cipher. One of the popular implementations of this cipher algorithm is Vigenere cipher and Playfair cipher. He used a mixed alphabet to encrypt the plaintext, but at random points he would change to a different mixed alphabet, indicating the change with an uppercase letter in the ciphertext. The sliding of the alphabets is controlled by key letters included in the body of the cryptogram" (Wikipedia article on Alberti cipher disk, accessed 03-30-2012). This generates an encrypted ciphertext that cannot be Gronsfeld This is also very similar to vigenere cipher. Ciphering wheels were one of the first devices that were developed to aid people in encoding messages. J = II This disk is attached inside another disk with the alphabet in regular order (blue). Thus, given a piece of ciphertext, known to have been enciphered using the Atbash Cipher, anyone who intercepts the message can easily decipher it to retrieve what was meant to be concealed. download the GitHub extension for Visual Studio, https://www.youtube.com/watch?v=4mNRU7h9Q_o.
