Show validation status of SSL certificates and send a warning, if a certificate is about to expire
All in the title.
Maybe this can be combined with a droplet in the dashboard so admin/reseller/customer can see their status of the certificates. And a background process or the ISPConfig cronjob itself could check against certificates which are about to expire in let's say 60 days? This would give the affected users enough time to renew the certificate.
At the moment, I've a cronjob that collects the filenames of all certificates by putting them into a textfile and after that, "ssl-cert-check" is checking the expiration date. But this is just a quick and dirty "solution". ISPConfig could retrieve those data directly after the certificate has been created/saved and an other service could use this information without even touching the system. Maybe through the API or so?
