11History of cryptography — The history of cryptography begins thousands of years ago. Until recent decades, it has been the story of what might be called classic cryptography that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids. In… …
12Pigpen cipher — The pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram.[1] The pigpen cipher (sometimes referred to as the masonic cipher, Freemason s cipher, Rosicrucian cipher, or Tic tac toe cipher) …
13Cryptography in Japan — There is not much cryptological history in Japan prior to the twentieth century, only a few simple codes were used and there seems to have been no practice of cryptanalysis at all.There seems to be almost no cryptology in Japan before the Warring …
14Biuro Szyfrów — The Biuro Szyfrów ([ˈbʲurɔ ˈʂɨfruf] ( listen), Polish for Cipher Bureau ) was the interwar Polish General Staff s agency charged with both cryptography (the use of ciphers and codes) and cryptology (the study of ciphers and codes,… …
15Salt (cryptography) — In cryptography, a salt consists of random bits, creating one of the inputs to a one way function. The other input is usually a password or passphrase. The output of the one way function can be stored rather than the password, and still be used… …
16Cipher — For other uses, see Cipher (disambiguation). Edward Larsson s rune cipher resembling that found on the Kensington Runestone. Also includes runically unrelated blackletter writing style and pigpen cipher. In cryptography, a cipher (or cypher) is… …
17C-52 (cipher machine) — The (Hagelin) C 52 and CX 52 were cipher machines manufactured by Crypto AG starting 1951/1952. These pin and lug type cipher machines were advanced successors of the C 38/M 209. The machine measures 8 1/2in times; 5 3/8in times; 4 3/8in. The… …
18Marian Rejewski — (probably 1932, the year he first solved the Enigma machine). Courtesy of Janina Sylwestrzak, Rejewski s daughter. Born Marian Adam Rejewski August 16, 1905(1905 0 …
19Purple (cipher machine) — This article is about the Japanese cipher Purple, also known as AN 1 (citation for AN 1 nomenclature for Purple?). For other Japanese ciphers, such as JN 25 which played a part in the Battle of Midway, see Japanese naval codes. In the history of… …
20Vigenère cipher — The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword. It is a simple form of polyalphabetic substitution.The Vigenère (pronEng|ˌviːdʒɪˈnɛəɹ, veedj ih nair )… …
