The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

本书以图配文的形式，详细讲解了6种最重要的密码技术：对称密码、公钥密码、单向散列函数、消息认证码、数字签名和伪随机数生成器。 第一部分讲述了密码技术的历史沿革、对称密码、分组密码模式（包括ECB、CBC、CFB、OFB、CTR）、公钥、混合密码系统。第二部分重点介绍了认证方面的内容，涉及单向散列函数、消息认证码、数字签名、证书等。第三部分讲述了密钥、随机数、PGP、SSL/TLS 以及密码技术在现实生活中的应用。

2009年，比特币诞生。比特币是一种通过密码编码，在复杂算法的大量计算下产生的电子货币。虽然是虚拟货币，比特币却引起了前所未有的全球关注热潮。 这一串凝结着加密算法与运算能力的数字不仅可以安全流通、换取实物，1比特币价值甚至曾高达8 000元人民币。有研究者认为比特币具备打破几千年来全球货币由国家垄断发行的可能性。在不经意间，比特币引起的金融新浪潮已悄然成型。 虚拟货币并不是新鲜事物，为什么只有比特币受到如此追捧？它激烈变动的价格行情更让投资者们担心：比特币的合理价格到底是多少？其价格的支撑体系又在哪里？如此剧烈的上下波动是不是预示着它的不稳定直至最终崩盘？ 作为国内首批参与并研究比特币的开拓者，《比特币：一个虚幻而真实的金融世界》作者们对这些问题都有着深刻的理解。本书从介绍比特币的概念出发，全面、系统地阐述了比特币的起源、发展、技术原理、生态圈等关键问题，还大胆畅想了比特币的现实应用、未来前景。 《比特币：一个虚幻而真实的金融世界》坦然面对比特币引发的种种争议，针对政府、货币体系等问题，以开放的态度、翔实的资料与读者交流，深入探讨比特币改变全球现行货币体系，朝货币发行非国家化的方向前进的可能性，揭示了比特币对现实金融业，甚至对未来世界的影响。 《比特币：一个虚幻而真实的金融世界》讲述的是一场伟大的货币实验，及一个虚幻而真实的金融世界。如何认识与思考这一实验，有助于理解互联网时代金融世界的逻辑。
