Certbot plugin for authentication using Njalla

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

Usage

Obtain an Njalla API token (found in the settings)
Install the plugin using pip3 install certbot-dns-njalla, or if you are using sudo with certbot use sudo -H pip3 install certbot-dns-njalla
Create a njalla.ini config file with the following contents and apply chmod 600 njalla.ini on it:
```
certbot_dns_njalla:dns_njalla_token=0000000000000000000000000000000000000000
```
Replace the zeroes with your Njalla API key and ensure permissions are set to disallow access to other users.
Run certbot and direct it to use the plugin for authentication and to use the config file previously created:
```
certbot certonly -a certbot-dns-njalla:dns-njalla --certbot-dns-njalla:dns-njalla-credentials njalla.ini -d domain.com
```
Add additional options as required to specify an installation plugin etc.
