Enhanced descriptions from Syndetics:

Cryptography in C and C++ mainly focuses on the practical aspects involved in implementing public key cryptography methods, such as the RSA algorithm that was released from patent protection. It also gives both a technical overview and an implementation of the Rijndael algorithm that was selected as the Advanced Encryption Standard by the U.S. government. Author Michael Welschenbach avoids complexities by explaining cryptography and its mathematical basis in terms a programmer can easily understand.

This book offers a comprehensive yet relentlessly practical overview of the fundamentals of modern cryptography. It contains a wide-ranging library of code in C and C++, including the RSA algorithm, completed by an extensive Test Suite that proves that the code works correctly. Readers will learn, step by step, how to implement a platform-independent library for the all-important multiprecision arithmetic used in modern cryptography. This is followed by an implementation of the cryptographic algorithms themselves.

The CD-ROM includes all the programs presented in the book, x86 assembler programs for basic arithmetical operations, implementations of the new Rijndael Advanced Encryption Standard algorithm in both C and C++, and more.

Includes bibliographical references (pages 421-425) and index.
