{"product_id":"1585755","title":"The Bombe: Prelude To Modern Cryptanalysis","description":"The \"bombe\" was a significant development in the evolution of the Allied cryptanalytic attack on the German Enigma cipher machine. From 1928 to 1938, Polish cryptanalysts, aided by the French, solved both the wiring of the three rotors used at the time and the indicator system, and through the use of a small electrical machine using Enigma rotors, created a card file which could anticipate the 6 by 17,576 possible rotor positions used in setting up the Enigma. \u003cp\u003e \u003c\/p\u003e\u003ctable style=\"box-shadow: none;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 25%; padding: 0em; padding-left: 5px; border: 0em;\"\u003e\n\u003cb\u003ePublisher\u003c\/b\u003e:\u003c\/td\u003e\n\u003ctd style=\"width: 75%; padding: 0em; padding-left: 5px; border: 0em;\"\u003eCenter for Cryptologic History\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 0em; padding-left: 5px; border: 0em;\"\u003e\n\u003cb\u003eBinding\u003c\/b\u003e:\u003c\/td\u003e\n\u003ctd style=\"padding: 0em; padding-left: 5px; border: 0em;\"\u003ePamphlet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 0em; padding-left: 5px; border: 0em;\"\u003e\n\u003cb\u003eCondition\u003c\/b\u003e:\u003c\/td\u003e\n\u003ctd style=\"padding: 0em; padding-left: 5px; border: 0em;\"\u003eVery Good\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e \u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003ci\u003eThis image is of the actual book.\u003c\/i\u003e\u003c\/p\u003e","brand":"Center for Cryptologic History","offers":[{"title":"Default Title","offer_id":49379881845013,"sku":"1585755","price":13.5,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0023\/2695\/4036\/files\/1585755.jpg?v=1775801300","url":"https:\/\/bookhaven.live\/products\/1585755","provider":"Book Haven","version":"1.0","type":"link"}
