External authenticator for Certbot
Automation - the main goal of letsencrypt is to make certificate management hassle-free. It works like that in most situations but each user has to deal with its own network configuration (NAT, firewalls, DNS, proxy, ...). The more mechanisms we have for verifying domain control, the easier the letsencrypt use becomes.
The biggest hassle with letsencrypt is verification of domain control as it requires your server to talk to letsencrypt servers and respond to challenges provided (changing DNS records, or adding files to certain locations). This process is necessary is it prevents random people getting certificates for your own domain. This plugin helps with domain verification process. It offers three modes:
- JSON mode - its output is in JSON format that can be processed by the certbot caller (e.g., Ansible).
- Handler mode - when it provides data for external authentication programs - e.g., Dehydrated that supports DNS updates for a number of registrars - here is the list.
- Manual mode - a fallback option when no automation is available and users have to do some changes (e.g., DNS updates) by hand.
We also support challenges for all three verification protocols:
- DNS
- HTTP
This plugin does not communicate with letsencrypt but it provides data for letsencrypt clients in the correct format so the domain control verification can be automated.
Installation - pip
s
pip install certbot
pip install certbot-ext-auth
Usage
Here is an example of a typical use:
certbot --text --agree-tos --email [email protected] \
--expand --renew-by-default \
--configurator certbot-external-auth:out \
--certbot-external-auth:out-public-ip-logging-ok \
-d example.com certonly
There are 3 main modes of operation:
- JSON mode (default)
- Text mode - fallback to the
manual.py
operation - Handler mode - auth performed by an external program. Supports Dehydrated and augmented mode.
If you want it to use as Authenticator and Installer, use
--configurator certbot-external-auth:out
certbot flag, for
Authenticator only use -a certbot-external-auth:out
In authenticator mode one can use certbot actions certonly
or
renew
. If installer mode is enabled too use run
action - typical
for Dehydrated hooks.
JSON Mode
JSON mode produces one-line JSON objects (\n
separated) with a
challenge to process by the invoker on the STDOUT.
After the challenge is processed, the invoker is supposed to send a new
line \n
character to the STDIN to continue with the process.
Note JSON mode produces also another JSON objects besides challenges,
e.g., cleanup and reports. The \n
is expected only for challenges
(perform/validate step).
If plugin is installed also as an Installer (or Configurator), it provides also commands related to the certificate installation.
Reporter was substituted to produce JSON logs so STDOUT is JSON only.
Arguments
--certbot-external-auth:out-public-ip-logging-ok
Skips public IP query check, required for JSON mode
--certbot-external-auth:out-text-mode
Defaults to manual.py text stdout, no JSON
--certbot-external-auth:out-handler
If set, enables handler mode. Commands are
sent to the handler script for processing.
Arguments are sent in ENV.
--certbot-external-auth:out-dehydrated-dns
If handler mode is enabled, compatibility
with dehydrated-dns hooks is enabled
Errors
Processing errors are indicated by non-zero return codes returned by this plugin.
Examples
The particular examples of verification methods and handler follows. At first the JSON mode examples are given, then handler examples follow.
Please note there is a --staging
argument in the following commands, meaning you will get just testing LetsEncrypt certificate.
Once this works for you, remove this argument so you get proper valid LetsEncrypt certificate.
DNS
Run the certbot with the following command:
certbot --staging \
--text --agree-tos --email [email protected] \
--expand --renew-by-default \
--configurator certbot-external-auth:out \
--certbot-external-auth:out-public-ip-logging-ok \
-d "bristol3.pki.enigmabridge.com" \
-d "bs3.pki.enigmabridge.com" \
--preferred-challenges dns \
certonly 2>/dev/null
Stderr contains string log / report, not in JSON format.

Future work
- Add compatibility with Dehydrated DNS hooks
- Communicate challenges via named pipes
- Communicate challenges via sockets
Manual Installation
To install, first install certbot (either on the root or in a virtualenv), then:
python setup.py install
Credits
The plugin is based on the
- Let's Encrypt nginx plugin
- certbot-external
manual.py
certbot plugin.
Once ticket 2782 is resolved this won't be needed.
