implemented based on Hurricane Electric DNS's Dynamic DNS (https://dns.he.net/docs) support.
## installation
you can install the plugin with:
snap set certbot trust-plugin-with-root=oksnap install certbot-dns-hesnap connect certbot:plugin certbot-dns-heyou should see dns-he in the output if the plugin has been installed
successfully:
certbot plugins | grep dns-he## usage
### quick start
_acme-challenge.<your-domain>, where
<your-domain> is the domain name for which you're trying to get a
certificate. e.g., create _acme-challenge.example.com if you are trying
to get a certificate for example.com or *.example.com.he-credentials.ini on your web server with the following
content:dns_he_keys={"_acme-challenge.<your-domain>": "<ddns-key>"}<ddns-key> is the dynamic DNS key you created for this name earlier.certbot command with necessary arguments, e.g.,
certbot certonly --authenticator dns-he --dns-he-credentials he-credentials.ini -d example.comIMPORTANT: Hurricane Electric only allows one dynamic DNS entry per name. as
a result, you are unable to generate a single certificate for both a root domain
and a wildcard domain (e.g. for both example.com and *.example.com), since
that requires setting two different TXT records with the same name (e.g.
_acme-challenge.example.com) at the same time.
### CLI options
the following options are added to certbot's command line interface:
--authenticator dns-he: (required) use Hurricane Electric DNS authenticator.--dns-he-credentials <file>: (required) specify path to a credential file--dns-he-propagation-seconds <seconds>: (optional) specify how long to wait
before the TXT record is verified. defaults to 10.### credential file
the credential file expects the following key-value pair:
dns_he_keys: a JSON object with fully quantified domain names as keys and
the corresponding dynamic DNS keys as valuesYou are about to open

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install certbot-dns-he, simply use the following command:
sudo snap install certbot-dns-he
Browse and find snaps from the convenience of your desktop using the snap store snap.
