check_certificates.php

This script checks whether the expiry date of the SSL certificates of one or multiple domains will be in less than X (default 25) days.

Usage:

check_certificates.php [<DOMAIN>[:days]] .. [<DOMAIN>[:days]]

Parameters:

• DOMAIN a domain to check. In case no DOMAIN-values are specified the domains from the [check_certificates]-section of the config.ini-file will be used.
• days minimum days before expiration. In case no days-value, or a value of 0, is specified for a domain, the default days-value of 25 will be used.

Note: As soon as command line parameters are used, the config.ini will be ignored.

Example:

check_certificates.php example.de:10

or alternatively

check_certificates.php

and the following section inside the config.ini

[check_certificates]
domains[example.de]=10

both indicate that the ssl certificate of the domain 'example.de' should be checked and a warning should be given in case the domain is less than 10 days valid.

Side note: We usually use the config.ini for configuration and trigger this script once a week through a crontab entry.
