Network Security with OpenSSL

Book Description
Most applications these days are at least somewhat network aware, but how do you protect those applications against common network security threats? Many developers are turning to OpenSSL, an open source version of SSL/TLS, which is the most widely used protocol for secure network communications. The OpenSSL library is seeing widespread adoption for web sites that require cryptographic functions to protect a broad range of sensitive information, such as credit card numbers and other financial transactions. Traditionally, getting something simple done in OpenSSL could take weeks. Network Security with OpenSSL gives you guidance to avoid pitfalls, and allows you to take advantage of the library?s advanced features. And, instead of bogging you down in the technical details of how SSL works under the hood, this book provides only the information that is necessary to use OpenSSL safely and effectively. The book details the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges.

OpenSSL is also a general-purpose cryptographic library with implementations of RSA, DSA, and DH public key algorithms; various message digest algorithms, such as MD5, SHA1, and RIPE-MD160; and a wide variety of symmetric ciphers, including 3DES, RC4, IDEA, and many others (the upcoming 0.9.7 release contains support for AES, the Advanced Encryption Standard). Support for X.509 certificates, various PKCS standards, and S/MIME v2 for secure electronic mail is also included. Instead of getting bogged down in the technical details of how SSL works under the hood, this book provides only the information that is necessary to use OpenSSL safely and effectively. The reader is taken step by step from understanding the challenges faced in communicating securely to using the OpenSSL tools to best meet those challenges. System and network administrators will 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 their own certification authority. Developers will 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.
