An Introduction to OpenSSL, Part Four: The SSL and TLS Protocols

by Holt Sorenson

This article completes the four-part series on OpenSSL, a library, written in the C programming language, that provides routines for cryptographic primitives utilized in implementing the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. OpenSSL also includes routines for implementing the SSL and TLS protocols. An application called openssl, which provides a command line interface to the library's routines, is also part of the distribution. This article will provide some...

An Introduction to OpenSSL Part One

by Holt Sorenson

This is the first article in a four-part series on OpenSSL, a library written in the C programming language that provides routines for cryptographic primitives utilized in implementing the Secure Sockets Layer (SSL) protocol. OpenSSL also includes routines for implementing the SSL protocol itself, and it includes an application called openssl that provides a command line interface to both sets of routines. This articles introduce some cryptographic tools that the SSL protocol has borrowed fro...
