Book Description
TLS is the most widely used cryptographic protocol today, enabling e-commerce, online banking, and secure online communication. TLS Cryptography in Depth will help you gain a deep understanding of how and why TLS works, how past attacks on TLS were possible, and how vulnerabilities that enabled them were addressed in the latest TLS version 1.3. By exploring the inner workings of TLS, you'll be able to configure it and use it more securely.
Starting with the basic concepts, you'll be led step by step through the world of modern cryptography, guided by the TLS protocol. As you advance, you'll be learning about the necessary mathematical concepts from scratch. Even seemingly arcane topics such as public-key cryptography based on elliptic curves will be explained with a view on real-world applications in TLS. With easy-to-understand concepts, you'll find out how secret keys are generated and exchanged in TLS, and how they are used to create a secure channel between a client and a server.
By the end of this book, you'll have understood the inner workings of TLS and how to configure TLS servers securely. Moreover, you'll have gained a deep knowledge of the cryptographic primitives that make up TLS and will be able to apply this knowledge in other security-related contexts.
