"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
This volume is designed to enable developers to use The OpenSSL library more effectively. It offers guidance on avoiding pitfalls, while taking advantage of the library's advanced features and provides the information necessary to use OpenSSL safely and effectively. In step-by-step fashion, the book details the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges. System and network administrator should benefit from the thorough treatment of the OpenSSL command-line interface, as well as from step-by-step directions for obtaining certificates and setting up certification authority. Developer should benefit from the in-depth discussions and examples of how to use OpenSSL in their own programs. Although OpenSSL is written in C, information on how to use OpenSSL with Perl, Python and PHP is also included.
