Hello everyone,
i just found "letsencrypt".
This is a free SSL license provider.
It creates certs that are available for 3 months (or sth like that)
You can create the certs via command prompt.
The "renew" works as well via the command prompt.
It saves the certs in "/etc/letsencrypt/live/<DomainName>/cert.pem" etc.
Am i able to say i-mscp to use that fileß
