Infoblox DNS Authenticator plugin for Certbot

certbot-dns-infoblox

Infoblox DNS Authenticator plugin for Certbot

This plugin automates the process of completing a dns-01 challenge by creating, and subsequently removing, TXT records using the Infoblox Remote API.

Installation

pip install certbot-dns-infoblox

Named Arguments

To start using DNS authentication for Infoblox, pass the following arguments on certbot's command line:

| --authenticator certbot-dns-infoblox:dns-infoblox | Select the authenticator plugin (Required) | | --certbot-dns-infoblox:dns-infoblox-credentials | Infoblox remote user credentials INI file. (Default: /etc/letsencrypt/infoblox.ini) | | --certbot-dns-infoblox:dns-infoblox-propagation-seconds | Waiting time for DNS to propagate before asking the ACME server to verify the DNS record. (Default: 10) |

If you are using certbot >= 1.0, you can skip the certbot-dns-infoblox: in the above arguments.

Credentials

An example credentials.ini file:

#
# Sample Infoblox INI file
#
dns_infoblox_hostname="infoblox.example.net"
dns_infoblox_username="my-wapi-user"
dns_infoblox_password="5f4dcc3b5aa765d61d8327deb882cf99"
dns_infoblox_view=""

The path to this file can be provided interactively or using the --dns-infoblox-credentials command-line argument. Certbot records the path to this file for use during renewal, but does not store the file's contents.

CAUTION: You should protect these API credentials as you would the password to your infoblox account. Users who can read this file can use these credentials to issue arbitrary API calls on your behalf. Users who can cause Certbot to run using these credentials can complete a dns-01 challenge to acquire new certificates or revoke existing certificates for associated domains, even if those domains aren't being managed by this server.

Certbot will emit a warning if it detects that the credentials file can be accessed by other users on your system. The warning reads "Unsafe permissions on credentials configuration file", followed by the path to the credentials file. This warning will be emitted each time Certbot uses the credentials file, including for renewal, and cannot be silenced except by addressing the issue (e.g., by using a command like chmod 600 to restrict access to the file).

Examples

To acquire a single certificate for both example.com and *.example.com, waiting 100 seconds for DNS propagation:

certbot certonly \
--authenticator dns-infoblox \
--dns-infoblox-credentials /etc/letsencrypt/.secrets/domain.tld.ini \
--dns-infoblox-propagation-seconds 100 \
--agree-tos \
--rsa-key-size 4096 \
-d 'example.com' \
-d '*.example.com'

Notes

This is based on the work in certbot-dns-ipsconfig and the package infoblox-client python package.

Note that all your issued certificates can be found in public databases, e.g., crt.sh.
