  Very nice book, but a little bit old

  I liked the book, the language and style are straight to the point and very clearly presented. Just be warned that on the AMAZON.CO.UK site the book is displayed as being published in 2014 - which would be very cool. Unfortunately it's published 2003 and this is obviously a mistake. So don't expect modern cryptographic primitives covered. Anyway it's well worth the read!

  Personal opinion

  It is a very interesting book.But I have been read this before...I was wrong when I bought it for second time

  I've read a large number of cryptography books. Very few of them come down to brass tacks. They give you a description of a few algorithms, their strengths and weaknesses, and leave it at that. Either that, or they describe in lovingly complex detail the implementation of a particular protocol, one usually so fraught with options and details that you wonder how, at the end of it, that anybody writes a conforming implementation. Practical Cryptography does neither of these things. It presents algorithm classes, why they exist, and what the best known algorithms are in each class. It explains how the various strengths and weaknesses of algorithms in each class combine to make a cryptosystem weaker or stronger. Then it goes on to show you how to use that information to build working cryptosystems. This book is NOT a careful discussion of the implementation details or plusses and minuses of particular algorithms. They give detailed implementation instructions and advice for some algorithms (such as RSA or Diffie-Hellman) that tend to end up being misunderstood or implemented poorly, but the main focus of the book is about putting all the information together to build a real system. This is something that I feel is sorely lacking in the field of cryptography as it stands in 2005 (when I last updated this review). The book does have a flaw. The authors present several algorithms and techniques that they recently invented and are not 'tried-and-true'. They present good arguments as to why they're secure. But the only real test of such things is lots of peer review and real-world testing. And, since they're new, they haven't been tested in that way. People have complained about the book's seeming schizophrenia. On one hand, the authors are trying to show you how to build a secure cryptosystem. On the other, they're telling you how hopeless a task it is to build one that has no vulnerabilities, even if you're an expert in such things. This can be annoying, but I more find it refreshing. Writing a secure cryptosystem is very hard. People should be aware that it is hard, and they are likely to make mistakes. It isn't something that should be attempted lightly. The current state of computer security is depressingly abysmal. People should be encouraged, as much as possible, to not contribute to the problem. I'm not following my own advice, and I am building a new cryptosystem. I have found this book a more valuable resource than any other book on cryptography that I have yet read. Even if you aren't building your own cryptosystem, I think you will find the insights this book has into complexity and design to be useful tools in evaluating other cryptosystems.
