An Introduction to OpenSSL, Part Three: PKI- Public Key Infrastructure
By Holt Sorenson
This is the third article in a 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. In the first article in the series, we discussed some of the basics of cryptography. The second article showed how to use OpenSSL’s openssl application to explore cryptographic basics. This article will introduce Public Key Infrastructure and show the commands that OpenSSL provides for managing PKI.
