This is a plugin for Certbot that uses the Gandi LiveDNS API to allow Gandi customers to prove control of a domain name.

1. Obtain a Gandi API token (see Gandi LiveDNS API)

2. Install the plugin using pip install certbot-plugin-gandi

3. Create a gandi.ini config file with the following contents and apply chmod 600 gandi.ini on it:

   certbot_plugin_gandi:dns_api_key=APIKEY
   

   Replace APIKEY with your Gandi API key and ensure permissions are set to disallow access to other users.

4. Run certbot and direct it to use the plugin for authentication and to use the config file previously created:

   certbot certonly -a certbot-plugin-gandi:dns --certbot-plugin-gandi:dns-credentials gandi.ini -d domain.com
   

   Add additional options as required to specify an installation plugin etc.

This plugin can be updated by running:

pip install certbot-plugin-gandi --upgrade

This plugin is particularly useful when you need to obtain a wildcard certificate using dns challenges:

certbot certonly -a certbot-plugin-gandi:dns --certbot-plugin-gandi:dns-credentials gandi.ini -d domain.com -d \*.domain.com --server https://acme-v02.api.letsencrypt.org/directory

You can setup automatic renewal using crontab with the following job for weekly renewal attempts:

* 1 * * 1 certbot renew -q -a certbot-plugin-gandi:dns --certbot-plugin-gandi:dns-credentials /etc/letsencrypt/gandi/gandi.ini --server https://acme-v02.api.letsencrypt.org/directory
