Part of the Integrated .NET Series, this book provides a practical and comprehensive treatment on implementing both cryptography and security features on the .NET platform — using the C# and VB .NET programming languages. It provides focused and detailed code examples that demonstrate the most important concepts, with commentary on how the code examples work. The book also provides a substantial mathematical and theoretical background on the underlying cryptographic concepts. After reading this book and experimenting with the provided example programs, the reader should have a good understanding of the major cryptographic algorithms and standard cryptographic programming techniques. Readers should also gain a solid understanding of how .NET security works and how to implement user-based and code access security in their own .NET programs.
