Applied Cryptography: Protocols, Algorithms, and Source Code in C

After a brief account of the history of cryptography, the latest data on encryption protocols and techniques are explained. Describes present-day applications ranging from electronic cash to anonymous messaging and current security concerns. The second section assumes fairly sophisticated knowledge of the C programming language and features numerous source code fragments. Practical implementations of the code are listed throughout the book's second half.

Praise for Applied Cryptography

"This book should be on the shelf of any computer professional involved in the use or implementation of cryptography."
