Preface
About This Book
The Internet is a dangerous place, more dangerous than most people realize. Many technical people know that it’s possible to intercept and modify data on the wire, but few realize how easy it actually is. If an application doesn’t properly protect data when it travels an untrusted network, the application is a security disaster waiting to happen.
The SSL (Secure Socket Layer) protocol and its successor TLS (Transport Layer Security) can be used to secure applications that need to communicate over a network. OpenSSL is an open source library that implements the SSL and TLS protocols, and is by far the most widely deployed, freely available implementation of these protocols. OpenSSL is fully featured and cross-platform, working on Unix and Windows alike. It’s primarily used from C and C++ programs, but you can use it from the command line (see Chapter 1 through Chapter 3) and from other languages such as Python, Perl, and PHP (see Chapter 9).
In this book, we’ll teach developers and administrators how to secure applications with OpenSSL. We won’t just show you how to SSL-enable your applications, we’ll be sure to introduce you to the most significant risks involved in doing so, and the methods for mitigating those risks. These methods are important; it takes more work to secure an SSL-enabled application than most people think, especially when code needs to run in multithreaded, highly interoperable environments where efficiency is a concern.
OpenSSL is more ...
