certbot plugin to allow acme dns-01 authentication of a name managed in cPanel.

certbot-dns-cpanel

Plugin to allow acme dns-01 authentication of a name managed in cPanel. Useful for automating and creating a Let's Encrypt certificate (wildcard or not) for a service with a name managed by cPanel, but installed on a server not managed in cPanel.

How to use

1. Install

First, install certbot and the plugin using pip:

pip install certbot certbot-dns-cpanel

2. Configure

Download the file credentials.ini.exemple and rename it to credentials.ini. Edit it to set your cPanel url, username and password.

# The url cPanel url
# include the scheme and the port number (usually 2083 for https)
certbot_dns_cpanel:cpanel_url = https://cpanel.exemple.com:2083

# The cPanel username
certbot_dns_cpanel:cpanel_username = user

# The cPanel password
certbot_dns_cpanel:cpanel_password = hunter2

3. Run

You can now run certbot using the plugin and feeding the credentials file.
For exemple, to get a certificate for exemple.com and www.exemple.com:

certbot certonly \
--authenticator certbot-dns-cpanel:cpanel \
--certbot-dns-cpanel:panel-credentials /path/to/credentials.ini \
-d exemple.com \
-d www.exemple.com

To create a wildcard certificate *.exemple.com and install it on an apache server, the installer plugin must be specified with the --installer option. You will need to install the apache plugin if it's not already present on your system.

pip install certbot-apache
certbot run \
--apache \
--authenticator certbot-dns-cpanel:cpanel \
--installer apache \
--certbot-dns-cpanel:cpanel-credentials /path/to/credentials.ini \
-d '*.exemple.com'

The certbot documentation has some additionnal informations about combining authenticator and installer plugins: https://certbot.eff.org/docs/using.html#getting-certificates-and-choosing-plugins
