long key cipher
21XOR cipher — In cryptography, a simple XOR cipher is a relatively simple encryption algorithm that operates according to the principles::A oplus 0 = A,:A oplus A = 0,:(B oplus A) oplus A = B oplus 0 = B,where oplus denotes the exclusive disjunction (XOR)… …
22Trivium (cipher) — Trivium is a synchronous stream cipher designed to provide a flexible trade off between speed and gate count in hardware, and reasonably efficient software implementation. It was submitted to the Profile II (hardware) of the eSTREAM competition… …
23Skipjack (cipher) — Infobox block cipher name = Skipjack designers = NSA publish date = 1998 (declassifed) key size = 80 bits block size = 64 bits structure = unbalanced Feistel network rounds = 32 cryptanalysis = 31 rounds are susceptible to impossible differential …
24E0 (cipher) — E0 is a stream cipher used in the Bluetooth protocol. It generates a sequence of pseudorandom numbers and combines it with the data using the XOR operator. The key length may vary, but is generally 128 bits. At each iteration, E0 generates a bit… …

26Purple (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… …
27ADFGVX cipher — In cryptography, the ADFGVX cipher was a field cipher used by the German Army during World War I. ADFGVX was in fact an extension of an earlier cipher called ADFGX. Invented by Colonel Fritz Nebel and introduced in March 1918, the cipher was a… …
28Lorenz cipher — Tunny redirects here. For the fish, see Tuna. The Lorenz SZ 40 and SZ 42 ( Schlüsselzusatz , meaning cipher attachment ) were German cipher machines used during World War II for teleprinter circuits. British codebreakers, who referred to… …
