Network Security with OpenSSL

John Viega, well known in the field of software security, has authored and co-authored several books and over 50 articles - including 15 academic research papers - primarily on this topic. He is a contributor to George Reese's forthcoming O'Reilly book, Java Enterprise Architecture and co-authored a lengthy appendix to the Wiley book Securing Java (McGraw and Felten). Matt Messier has been writing free software for 11 years. In the early '90s, he wrote prominent software for BBSs, including ProChat, an external door program for PCBoard systems running multiple nodes in a network environment (LANtastic or Novell). The past five years, he contracted to Lotus as a software engineer working on Lotus 1-2-3, Freelance Graphics. Matt has integrated OpenSSL with the LPC programming language, and used it to add SSL support to several real-world applications, including a telnet implementation. Pravir Chandra, programming since he was 14, became interested in security at Case Western University, where he gained work-related experience in secure network design, computer forensics, secure software design and programming language-level security. He became an expert on language-level security. Pavil's extensive work on open-source projects include an entropy collection system and cryptographic random number generation implementation for the Linux kernel, and RATS (Rough Auditing Tool for Security), a program that drastically reduces the man hours required to perform source audits.

"If you have struggled with OpenSSL and the supplied documentation then you will regret the amount of time that you have wasted before finding this book. If you are planning to use OpenSSL then you need to buy a copy - it's essential reading. What is more surprising is that even if you don't plan to use OpenSSL, then downloading it and trying out the examples in the book could be the education in practical cryptography you really need. What more can I say of any book, other than that I certainly won't be lending it to anyone else? It's going to remain firmly chained to my bookshelf for the foreseeable future - and no, you can't borrow it." - Mike James, VSJ, October 2003
