WGU Introduction to Cryptography C839 (EC-Council CES) CrypTool Software which allows encryption of text using historic algorithms The Enigma Machine In World War II the Germans made use of an elect... ro-mechanical rotor based cipher Known as The Enigma Machine. Allied cipher machines used in WWII included the British TypeX and the American SIGABA. The ADFGVX Cipher invented by Colonel Fritz Nebel in 1918. The key for this algorithm is a six-by-six square of letters, used to encode a 36-letter alphabet. The Playfair Cipher invented in 1854 by Charles Wheatstone. The Playfair cipher uses a five-by-five table containing a keyword or key phrase. Breaking the Vigenère Cipher In 1863, Friedrich Kasiski was the first person to publish a successful general attack on the Vigenère Cipher The Vigenère Cipher This is perhaps the most widely known multi-alphabet substitution cipher. invented in 1553 by Giovan Battista Bellaso. Uses a series of different Caesar ciphers based on the letters of a keyword. The Cipher Disk The cipher disk was invented by Leon Alberti in 1466. each time you turned the disk, you used a new cipher. It was literally a disk you turned to encrypt plaintext. Multi-Alphabet Substitution Use of multiple substitution alphabets. Example:Cipher Disk, Vigenere Cipher, Enigma Machine [Show More]
