Overview

"Cryptography in C and C++" not only explains the theory behind public key cryptography methods such as the recently released from patent RSA algorithm, it also presents a technical overview of the Rijndael algorithm that was recently selected "Advanced Encryption Standard" by the U.S. Government. See http://csrc.nist.gov/encryption/aes/rijndael/ for more information.
This book is comprehensive. Among its other features, it gives the step-by-step development of a program package for arithmetic and cryptography, including the all-important multiprecision packages needed for cryptography. The author avoids mathematical complexities yet still manages to explain in terms a programmer can understand the mathematical basis for these functions.
The CD-ROM contains not only programs presented in the book, it even contains 80x86 assembler programs for key pieces. This code can be used to boost performance on arithmetic on Windows and Linux platforms. The CD also contains implementations of the new Rijndael Advanced Encryption Standard algorithm in both C and C++.
- Only book on the market to cover Rijndael, a new data encryption standard.@- Gives explanations of the ideas behind the algorithms, yet avoids complicated mathematics@- Relentlessly practical@- Far more up-to-date than any other title on the subject

    The reference in Cryptography for developpers

    If you are interested or involved in any way in both C/C++ development and cryptography, this book is a must. It contains all the bases and details of the most important algorithms, RSA and Rijndael: - If you need mathematical information about cryptography everything is clearly explained. - If (like me)you want to experiment with practical cryptography, you will be using the RSA routines in minutes, on both VC++ or Linux. The code is simple, clear, compact. Great book !
