External authenticator for Certbot

## 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:

1. JSON mode - its output is in JSON format that can be processed by the certbot caller (e.g., Ansible).
2. 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].
3. 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
* TLS-SNI

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

```bash
pip install certbot
pip install certbot-external-auth
```

## Usage

Here is an example of a typical use:

```bash
certbot --text --agree-tos --email [e-mail] \
--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 for verification methods and handler follows.
At first the JSON mode examples are given, then handler examples follow.

### DNS

Run the certbot with the following command:

```bash
certbot --staging \
--text --agree-tos --email [e-mail] \
--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.

Stdout:

```

After `{"cmd": "validate"}` message the client waits on `\n` on the standard input to continue with the validation.

### 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.

```bash
certbot --staging \
--text --agree-tos --email [e-mail] \
--expand --renew-by-default \
--configurator certbot-external-auth:out \
--certbot-external-auth:out-public-ip-logging-ok \

## 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`).


```bash
certbot --staging \
--text --agree-tos --email [e-mail] \
--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 \

## 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:

```bash
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.
