Synopsis
========

| **dehydrated-cron**

Description
===========

**dehydrated** is a client for ACME-based Certificate Authorities, such as LetsEncrypt. It can be used to request and obtain TLS certificates from an ACME-based certificate authority.

The **dehydrated-cron** script runs dehydrated once per day and on system reboot for an automatic certificate renewal.

It uses the dehydrated '--keep-going' option to keep going after encountering an error while creating/renewing multiple certificates. Afterwards it also removes all unused certificates by using the dehydrated '--cleanup-delete' option.
