"WebThe German firm produced Schlüsselzusatz SZ40, a state-of-the-art, 12-wheel cipher machine for encrypting messages. The British group worked on this problem from June 1941 to January 1942, when William Tutte (1917-2002), using a method invented by Alan Turing, singlehandedly reconstructed the SZ40 without ever having seen it.

The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib), and its encrypted version (ciphertext). These can be used to reveal further secret information such as secret keys and code books. The term "crib" originated at Bletchley Park, … See more The usage "crib" was adapted from a slang term referring to cheating (e.g., "I cribbed my answer from your test paper").
