Part 5: Running a Mini-CA

In this part, we will learn how to use OpenSSL command-line utilities to run a mini-Certificate Authority (CA) that can issue certificates for internal usage in an organization. A mini-CA can be useful in organizations for establishing internal Public Key Infrastructure, gaining control of internally used certificates, and saving costs on ordering certificates from commercial CAs. The usage of a mini-CA will be illustrated using configuration files and command-line examples.
