Kryptologia jest trudna? Może, ale na pewno nie z tą książką! Jeśli słowo "szyfr" budzi w Tobie przyjemny dreszczyk emocji, mamy dla Ciebie prawdziwą gratkę. Już za chwilę poznasz największe tajemnice ludzkości. Prezentowane w tej książce tajemnicze kody służyły dyplomatom, armiom pierwszej i drugiej wojny światowej, wreszcie zimnowojennym szpiegom. Były kamyczkami, które wywołały lawinę rewolucji informatycznej. Bez żadnej przesady - oto szyfry, które decydowały o losach świata. I wciąż o nich decydują. Kryptologia bardzo intensywnie się rozwija. Dziś jest wręcz niezbędna do naszego funkcjonowania. Warto poznać jej podstawy, tak samo jak wypada się orientować w historii, fizyce czy biologii - choćby po to, by być na bieżąco ze współczesną nauką. Poza tym szyfrowanie i deszyfrowanie stanowi znakomitą gimnastykę dla umysłu i dobry sposób na kreatywne spędzenie czasu. Co więcej, prezentowane sposoby ukrywania wiadomości mogą nadal służyć zgodnie ze swoim pierwotnym przeznaczeniem - do ukrywania tego, co niekoniecznie chcemy przekazać wprost...
