Make sure your DNS has a short TTL value!
Your certificate and private key will be temporarily stored on this server, but permanently erased after about 30 minutes.
If you are concerned about the security and safety of the above, don't use this site.
Yes, only wildcard certificates, ON YOUR MAIN DOMAIN, nothing else.
Cookies need to be enabled.
Be patient while the DNS propagates, but you only have about 30 minutes.
