In today's world, security is a top concern for businesses worldwide. Without a secure computer system, you don't make money, you don't expand, and-bottom line-you don't survive. Cryptography holds great promise as the technology to provide security in cyberspace. Amazingly enough, no literature exists about how to implement cryptography and how to incorporate it into real-world systems. With Practical Cryptography, an author team of international renown provides you with the first hands-on cryptographic product implementation guide, bridging the gap between cryptographic theory and real-world cryptographic applications.

This follow-up guide to the bestselling Applied Cryptography dives in and explains the how-to of cryptography. You'll find discussions on:

• Practical rules for choosing and using cryptographic primitives, from block ciphers to digital signatures
• Implementing cryptographic algorithms and systems in a secure way on today's computers
• A consistent design philosophy to ensure that every part of the system achieves the required security level
• Why security affects every part of the system, and why it has to be a primary goal of the project
• How simple interfaces for cryptographic primitives reduce system complexity and increase system security
