With the latest release (to the CURRENT tier, which is considered “release candidate” worthy) of cPanel/WHM, you can now obtain completely free 90 day SSL certificates from cPanel themselves (backed by Comodo) for your web site. This requires version 58 of cPanel/WHM. These certificates will automatically be renewed.
This blog is already using them, and long may I do so. As I’ve said earlier, obtaining SSL certificates for securing usernames and passwords or e-commerce is now the cheapest (e.g. free) it’s ever been. There’s absolutely no excuse to run a web site that’s not secured by an SSL certificate now. None.
If you don’t want to use Comodo backed SSL certificates, there will be a Let’s Encrypt plugin for cPanel/WHM appearing soon from cPanel themselves.
