Cryptographic slide rule used as a calculation aid by the Swiss Army between 1914 and 1940. For example, in a Caesar cipher of shift 3, A would become D, B would become E, Y would become B and so on. This is especially true if each key length is individually prime. Weltkrieg — Das Codebuch des Papstes — Enigma. This constituted an application of. Bei lediglich 25 sinnvollen Schlüsseln ist es also kein allzu großer Aufwand, alle Schlüssel zu testen, bis sich ein sinnvoller Klartext ergibt Brute-Force-Analyse. A better approach for repeating-key ciphers is to copy the ciphertext into rows of a matrix with as many columns as an assumed key length and then to compute the average with each column considered separately.
