Pro Cryptography and Cryptanalysis, 1st ed.
Creating Advanced Algorithms with C# and .NET

Utilize this comprehensive, yet practical, overview of modern cryptography and cryptanalysis to improve performance. Learn by example with source code in C# and .NET, and come away with an understanding of public key encryption systems and challenging cryptography mechanisms such as lattice-based cryptography.

Pro Cryptography and Cryptanalysis is for the reader who has a professional need or personal interest in developing cryptography algorithms and security schemes using C# and .NET. You will learn how to implement advanced cryptographic algorithms (such as Elliptic Curve Cryptography Algorithms, Lattice-based Cryptography, Searchable Encryption, Homomorphic Encryption), and come away with a solid understanding of the internal cryptographic mechanisms, and  common ways in which the algorithms are correctly implemented in real practice. With the new era of quantum computing, this book serves as a stepping stone to quantum cryptography, finding useful connections between current cryptographic concepts and quantum related topics.

What You Will Learn

• Know when to enlist cryptography, and how it is often misunderstood and misused
• Explore modern cryptography algorithms, practices, and properties
• Design and implement usable, advanced cryptographic methods and mechanisms
• Understand how new features in C# and .NET impact the future of cryptographic algorithms
• Use the cryptographic model, services, and System.Security.Cryptography namespace in .NET
• Modernize your cryptanalyst mindset by exploiting the performance of C# and .NET with its weak cryptographic algorithms
• Practice the basics of public key cryptography, including ECDSA signatures
• Discover how most algorithms can be broken

Who This Book Is For

Information security experts, cryptologists, software engineers, developers, data scientists, and academia who have experience with C#, .NET, as well as IDEs such as Visual Studio, VS Code, or Mono. Because this book is for an intermediate to advanced audience, readers should also possess an understanding of cryptography (symmetric and asymmetric) concepts.
