If you've ever made a secure purchase with your credit card over the Internet, then you have seen cryptography, or "crypto," in action. From Stephen Levy--the author who made "hackers" a household word--comes this account of a revolution that is already affecting every citizen in the twenty-first century. Crypto tells the inside story of how a group of "crypto rebels"&#151nerds and visionaries turned freedom fighters&#151teamed up with corporate interests to beat Big Brother and ensure our privacy on the Internet. Levy's history of one of the most controversial and important topics of the digital age reads like the best futuristic fiction. Cryptography is of huge importance today as codes are used for securing the Internet, mobile phones and electronic transactions. This book traces the development of this science and describes the conflicts between those that want to keep codes weak and those who want strong codes available to all.
