This is a small wrapper, written in bash, with minimal dependencies to create/renew easily Let'encrypt certificates using dns challenge and Gandi Live DNS API.

This wrapper is composed of two scripts :

  • run.sh : main script which does some background check, then call dehydrated to create / renew Let's encrypt certs
  • hook.sh : Dehydrated hook to handle Gandi Live DNS API.

This scripts can be used from minimal environment like OpenWRT router for example.
