SUSE Certified Engineer - Managing Encryption

In this hands-on lab, you'll be getting more familiar and experienced in using OpenSSL to create your own Certificate Authority (CA), so that you can sign your own certificate requests. You'll set up the Root Certificate Authority, generate a Certificate Signing Request (CSR), and then use that request to generate the end result — a server certificate. You'll then use the `gpg` command to generate and query your own GPG public and secret keys, and use that information to encrypt a data file and then decrypt it, comparing the file contents before and after.
