Hurricane Electric DNS Authenticator plugin for Certbot

Install cerbot-dns-he to your Certbot's environment with pip. For example, the line below works for me after running certbot-auto.

$ sudo /opt/eff.org/certbot/venv/bin/pip install cerbot-dns-he

You can also use git+https://github.com/TSaaristo/certbot-dns-he.git or clone the repository and install from the directory, but pip is recommended.

Create a configuration file with your username and password:

certbot_dns_he:dns_he_user = Me
certbot_dns_he:dns_he_pass = my HE password

and chmod it to 600:

$ chmod 600 dns_he.ini

Then request a certificate with something like:

$ certbot-auto certonly \
  -a certbot-dns-he:dns-he --certbot-dns-he:dns-he-propagation-seconds 30 \
  --certbot-dns-he:dns-he-credentials /home/me/dns_he.ini -d 'mydomain.com,*.mydomain.com' \
  --server https://acme-v02.api.letsencrypt.org/directory --agree-tos \
  --manual-public-ip-logging-ok --preferred-challenges dns -m me@email.com

You're done!

These are stored in cerbot's renewal configuration, so they'll work on your automatic renewals.
