Dan Brown, «Digital Fortress»Dan Brown | ISBN-10: 1593975635 | 2004 | English | MP3 (32kb/s) | 164 MB
Susan Fletcher, a brilliant mathematician and head of the National Security Agency's cryptography division, finds herself faced with an unbreakable code named "Digital Fortress" that TRANSLTR cannot break. TRANSLTR is the NSA's three-million-processor supercomputer that can quickly crack encrypted data via the brute force method, with some codes broken in more than three hours and others within minutes. The code of "Digital Fortress" is written by Japanese cryptographer Ensei Tankado, a fired NSA employee who is displeased with the agency's intrusion into people's privacy. Tankado posts a copy of Digital Fortress on his website, encrypted with itself, and auctions the passkey to unlock the algorithm on his website, threatening that his accomplice "North Dakota" will release the algorithm for free if he dies. Tankado is found dead in Seville, Spain. Fletcher and her fiance, David Becker, a skilled linguist with eidetic memory, must find a solution to stop the spread of the code.
