Dynu DNS Authenticator plugin for Certbot

Project description


Dynu DNS Authenticator plugin for Certbot.

This plugin is built from the ground up and follows the development style and life-cycle of other certbot-dns-* plugins found in the Official Certbot Repository.


pip install --upgrade certbot
pip install certbot-dns-dynu


$ certbot plugins --text

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* certbot-dns-dynu:dns-dynu
Description: Obtain certificates using a DNS TXT record (if you are using
Dynu for DNS.)
Interfaces: IAuthenticator, IPlugin
Entry point: dns-dynu = certbot_dns_dynu.dns_dynu:Authenticator



The credentials file e.g. ~/dynu-credentials.ini should look like this:

certbot_dns_dynu:dns_dynu_auth_token = AbCbASsd!@34


certbot ... \
        --authenticator certbot-dns-dynu:dns-dynu  \
        --certbot-dns-dynu:dns-dynu-credentials ~/dynu-credentials.ini \


Why such long name for a plugin?

This follows the upstream nomenclature: certbot-dns-<dns-provider>.

Why do I have to use : separator in the name? And why are the configuration file parameters so weird?

This is a limitation of the Certbot interface towards third-party plugins.

For details read the discussions:


Create a virtualenv, install the plugin (editable mode), spawn the environment and run the test:

virtualenv -p python3 .venv
. .venv/bin/activate
pip install -e .
docker-compose up -d
./test/ test/dynu-credentials.ini
