This book discusses the concepts behind modern cryptography and details how programmers can use cryptography to maintain the privacy of computer data. It describes dozens of cryptography algorithms, gives practical advice on how to implement them into cryptographic software, and shows how they can be used to solve security problems. Covering recent developments in practical cryptographic techniques, it teaches readers how to build security into their software and systems. This book not only demonstrates the algorithms but also demonstrates how to implement them using C++.

Saiful Azad received his PhD in information engineering at University of Padova, Italy in 2013. He completed his B.Sc. from IUT, Bangladesh in computer and information technology, and M.Sc. from IIUM, Malaysia in computer and information engineering. After completion of his PhD, he joined as a faculty member in the Department of Computer Science at American International University - Bangladesh (AIUB). He started working on Underwater Acoustic Networks during his PhD and still it remains his main focus of research. His research interests also lie in designing and implementing communication protocols for any network architecture, QoS issues, network security, and simulator design. He is one of the developers of the DESERT underwater simulator. He is also the author of more than 30 scientific papers published in international peer-reviewed journals or conferences. He has served as a technical program committee member in numerous international conferences/workshops. He also serves as a reviewer of a couple of renowned peer-reviewed journals and conferences.

Al-Sakib Khan Pathan earned his PhD (MS leading to PhD) in computer engineering in 2009 from Kyung Hee University in South Korea. He earned his BS in computer science and information technology from IUT, Bangladesh, in 2003. He is currently an assistant professor in the Computer Science Department of IIUM. Until June 2010, he served as an assistant professor in the Computer Science and Engineering Department of BRAC University, Bangladesh. Prior to holding this position, he worked as a researcher at the networking lab of Kyung Hee University, South Korea, until August 2009.

Dr. Pathan's research interests include wireless sensor networks, network security, and e-services technologies. He has been a recipient of several awards/best paper awards and has several publications in these areas. He has served as chair, an organizing committee member, and a technical program committ
