Implementing SSL/TLS Using Cryptography

Hands-on, practical guide to implementing SSL and TLS protocols for Internet security If you are a network professional who knows C programming, this practical book is for you. Let's get down to a practical implementation of SSL and TLS SSL/TLS is a standardized, widely implemented, peer-reviewed protocol for applying cryptographic primitives to arbitrary networked communications. It provides privacy, integrity, and a measure of authenticity to otherwise inherently untrustworthy network connections. While most books detail the protocol, this one is intended to provide you with a nearly complete SSL/TLS library, developed incrementally using C code. Whether or not you have a working knowledgeof cryptography, you'll find this practical guide helps you understand the internals of these libraries so that, when it comes time to use one, you will have a firm understanding of what takes place at each stage. Understand secure sockets and the HTTP protocol Learn to protect against eavesdroppers with symmetric cryptography Secure key exchanges over an insecure medium with public key cryptography and boost security with elliptic curve cryptography Examine the use of digital signatures and X.509 certificates Develop a usable, secure communications protocol with client-side TLS Add server-side TLS 1.0 support Use SSL in advanced situations, including safely reusing key material with sessionresumption and verifying identity with client authentication Go to to find code and other features related to this book Hands-on, practical guide to implementing SSL and TLS protocols for Internet security If you are a network professional who knows C programming, this practical book is for you. Focused on how to implement Secure Socket Layer (SSL) and Transport Layer Security (TLS), this book guides you through all necessary steps, whether or not you have a working knowledge of cryptography. The book covers SSLv2, TLS 1.0, and TLS 1.2, including implementations of the relevant cryptographic protocols, secure hashing, certificate parsing, certificate generation, and more. Coverage includes: Understanding Internet Security Protecting against Eavesdroppers with Symmetric Cryptography Secure Key Exchange over an Insecure Medium with Public Key Cryptography Authenticating Communications Using Digital Signatures Creating a Network of Trust Using X.509 Certificates A Usable, Secure Communications Protocol: Client-Side TLS Adding Server-Side TLS 1.0 Support Advanced SSL Topics Adding TLS 1.2 Support to Your TLS Library Other Applications of SSL A Binary Representation of Integers: A Primer Installing TCPDump and OpenSSL Understanding the Pitfalls of SSLv2 Set up and launch a working implementation of SSL with this practical guide.
