Free SSL Certificates
If you have your own domain, like roysdon.net, you may at some point want to be able to login to a webpage, receive and send email, transfer files with ftp, and even connect to your own network with a virtual private network, or vpn. You'll want to do this securely so you know no one is watching your login authentication or data that you're transmitting.
Secure Sockets Layer, or SSL, is the means to accomplish this. Then you can log in from a PC and trust that your authentication and data isn't going to be intercepted or modified on the way from the PC to the server.
In order to use SSL you need at least one SSL certificate. While you can create an SSL certificate and self-sign it, the rest of the world will not trust it, and it'll cause error messages about being untrusted.
The important step here to have the rest of the world trust your certificate is to have your SSL certificate signed by a Root Certificate Authority, or Root CA. Root CA's normally charge for this service, but you can get a CA-signed SSL certificate for free.
