"Dr. Bishop chose an approach that would allow readers to cover the mathematical material in the book, to see the code which implemented those principles, then simply open their browser and click on an HTML file to view the concepts they had just learned...this is the first crypto book that offers this kind of interactivity."

"The text is well written, easy to read.  Good examples and exercises follow each chapter.  The topics and examples covered serve well for juniors/seniors and first-year grad students."

"At many universities this book would find a natural home after a first programming and first discrete math class, and many students will be intrigued to find that cryptography is to be done and not just studied."

-  Charlie Colbourn
Arizona State University

"I'd be happy to have this book on my shelf, and when I teach cryptography, I would be happy to use it in my classroom and recommend it to my students... given the importance of the topic, the current choice of implementation platform, and the accuracy of the treatment, I think this is well done."
