Cryptography in C and C++

This book is really good for beginners in cryptography. However, the most useful thing in the book is the source code, which can be used for programming your own crypto protocols. I would give this 5/5 rating.

This book offers a practical and relatively easy to read description of implementing cryptography algorithms, especially RSA, in software. Most books in the field are highly mathematical. This book covers all of the necessary mathematics, but also explains how to efficiently implement the mathematics in C. It covers many of the real-life issues in building security software. As a researcher in the field, I found the book very helpful.

Don't even try to do crypto routines in C/C++ without this book. It will save you a lot of heartache. Read it!

Finally a very good solution is available to overcome limitations in built-in data types!!we are a group of students from Velammal engineering college in India doing a project in cryptography.But we had problem in handling very large numbers that most of the cryptographic algorithms require.We searched the net but in vain it was similar to flogging a dead horse. And then we found the book "CRYPTOGRAPHY IN C" by MICHAEL WELSCHENBACH.A book we recommend for all the students interested in cryptography.Not just cryptography but to any other problem involving very large numbers. The perfect guide to break the chains of built-in data types. A must for every professional and students interested in Cryptography.Anyone having some knowledge in C can refer this wonderful book and wonder why such ideas never occured to them.

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 !
