A good book for those who know nothing about cryptography and want to read it purely out of interest. I would not recommend this book to a serious student or professional because its really just level 1. This book is like an arabian nights tale compared to the coursera cryptography class. But if that's what you are looking for (that's what I was looking for..), go ahead and buy it.

It is a very good book.
All content are very nice with suitable and good example.
I purchased this for The MCA SEM 3 Exam.
Images are good which are for examples and for explaining.

Nice book for networking

Excellent product ...got what I needed.....only slow delivery......

good
