From the moment the first secret message was sent, others were busy trying to decipher it. By rearranging, substituting, or transposing symbols, any message can be encoded or decoded -- if you know how. \u003cp\u003e\u003c\/p\u003e\u003ci\u003eSecrets of Making and Breaking Codes\u003c\/i\u003e is a practical field manual designed to teach you the basic mechanics of enciphering and deciphering communications. The author has used his extensive knowledge of and experience in electronic communications and languages -- as well as his decades of fascination with secret codes -- to demystify the field of cryptology. \u003cp\u003e\u003c\/p\u003eHamilton Nickels uses plain, uncomplicated English and simple, workable systems that rely on neither advanced mathematics, nor on ethereal philosophies. This is the only hands-on guide to both the simplest cipher schemes -- that need little more than scratch paper and a pencil to crack -- as well as more sophisticated codes that use one-time code books, pocket calculators, and the most advanced computer-based systems used by the military and diplomatic corps of most governments. \u003cp\u003e\u003c\/p\u003eLetting the wrong eyes see a secret message can often make the difference between victory and defeat, success and failure, life and death. \u003ci\u003eSecrets of Making and Breaking Codes\u003c\/i\u003e will make mastering codes easier.\u003cbr\u003e","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50395040383249,"sku":"CIN1629142069G","price":0.0,"currency_code":"AUD","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":52934729040145,"sku":"CIN1629142069VG","price":0.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1629142069.jpg?v=1750800180","url":"https:\/\/www.worldofbooks.com\/en-au\/products\/secrets-of-making-and-breaking-codes-book-hamilton-nickels-9781629142067","provider":"World of Books ","version":"1.0","type":"link"}
