Question
Is there a way to create a free 90days wildcard Ca certificate on ubuntu 18.04 ?

I find my CA certificate is single domain certificate and it doesn’t support mail server. It looks like I need a wildcard Ca certificate. I searched on the google and find “https://certbot.eff.org/docs/using.html#dns-plugins”. Can you tell me how create a 90days wildcard CA certificate using certbot on the ubunutu18.04 ? Thanks a lot.

Hi @zhiweny1122,
I’ll assume you’ve actually installed certbot already so we can just continue with the actual configuration for installing a wildcard certificate.
Let’s say we have a test domain example.com. To actually install a wildcard for it, we’ll need to run the following command from the droplet
This should be enough for the wildcard to be installed.
