Renew certificates and notify on expiration
===========================================

[◀ Go back to main README](../README.md)

Description
-----------

This script tries to download and renew certificates, then notifies about
certificates that are still about to expire.

Requirements and installation
-----------------------------

Just install the script:

    $ScriptInstallUpdate check-certificates;

Configuration
-------------

The expiry notifications just require notification settings for e-mail and
telegram.

For automatic download and renewal of certificates you need configuration
in `global-config-overlay`, these are the parameters:

* `CertRenewPass`: an array of passphrases to try
* `CertRenewUrl`: the url to download certificates from

Certificates on the web server should be named `CN.pem` (`PEM` format) or
`CN.p12` (`PKCS#12` format).

Usage and invocation
--------------------

Just run the script:

    / system script run check-certificates;

... or create a scheduler for periodic execution:

    / system scheduler add interval=1d name=check-certificates on-event="/ system script run check-certificates;" start-time=startup;
