This new edition of the cryptography classic provides you with a comprehensive survey of modern cryptography. The book details how programmers and electronic communications professionals can use cryptography-the technique of enciphering and deciphering messages-to maintain the privacy of computer data. It describes dozens of cryptography algorithms, gives practical advice on how to implement them into cryptographic software, and shows how they can be used to solve security problems. Covering the latest developments in practical cryptographic techniques, this new edition shows programmers who design computer applications, networks, and storage systems how they can build security into their software and systems.

What's new in the Second Edition?

The best book about cryptography
From chapter one to the very end of the book, this is shurly the best thing ever written about data security. I would like specially to congratulate Shneier on the code samples, that are with the best I have ever seen.

Excellent for learning the big picture
This book is an excellent overall book if you are trying to learn about the various numerical implementations and requirements for performing enciphering and deciphering. It explains the various functional requirements of Cryptology such as authentication and integrity, then goes on to explain the various types of protocols required to perform these functions. It does a good job explaining the principals of the mathematics behind various functions such as one way hash functions, digital signatures and the principals of public key ciphering. algorithms. It also does an excellent job of talking about the various named security protocols that implement the various requirements such as MD5 hashing, Diffie-Hellman key exchange, the DES cryptic algorithm and many many more. This book falls somewhat short when it comes to full explaination of how to implement the mathematics in a computer program, since there are no code examples for determining if a very large number is prime, and much of the other math contains code using integers only and does not perform the long number manipulation required for a secure algorithm. This is the only reason I did give this book 5 stars. If you are trying to figure out the functionality of cryptology, and how the various algorithms fit in, this book is for you. If you already are familiar with security algorithms and you want to find practical math and code, this book may help you some, but you will require something more. Overall this book is still an excellent book.
