WebMar 23, 2024 · The above holds if the crib WITH starts at a position where it is encrypted as (W,I) (T,H) which you should try first so m even.). If it is at another position, we get more equations (6 for 3 pairs of cipher text) in 2 more unknowns (the 2 two missing plaintext characters before and after the crib) and have to solve those (easy by computer).

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"). A "crib" originally was a literal or interlinear translation of a foreign-language text—usually a See more 1. ^ Gordon Welchman, The Hut Six Story: Breaking the Enigma Codes, p. 78. 2. ^ Michael Smith, "How It Began: Bletchley Park Goes to War," in See more • Cadix • Cryptanalysis of the Enigma • Kiss (cryptanalysis) • PC Bruno • Polish Cipher Bureau See more
