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

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.

DNS installer

Certbot is running with action run which causes also Installer
plugin part to work. The installer is the same for all validation modes
so it is demonstrated only once.

Example - Dehydrated

The following section demonstrates usage of the plugin with
Dehydrated DNS hooks.

Note the certbot is run with action run so deployment callbacks are
called too.

In this repository there is
dehydrated-example.sh
which is a hook stub used in this example. When using your own handler
please make sure the file is executable (has x flag,
chmod +x handler-file).

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.
