letsencrypt-inwx

A small cli utility for automating the letsencrypt dns-01 challenge for domains hosted by inwx. This allows you to obtain wildcard certificates from letsencrypt.

Installation

Ubuntu / Debian

• Build the .deb package or download it from releases and install it with sudo dpkg -i <path_to_the_deb_file>

Other linux

• Build the executable and copy it to /usr/bin/
• Copy both certbot scripts from ./etc/ to /usr/lib/letsencrypt-inwx/

Usage

With certbot

• Put your inwx login data seperated by a newline into /etc/letsencrypt-inwx-cred
• Make sure the file is only readable for root sudo chmod 600 /etc/letsencrypt-inwx-cred
• You can now get certificates from certbot by running sudo certbot certonly -n --agree-tos --email <your_email> --manual --preferred-challenges=dns --manual-auth-hook /usr/lib/letsencrypt-inwx/certbot-inwx-auth --manual-cleanup-hook /usr/lib/letsencrypt-inwx/certbot-inwx-cleanup --manual-public-ip-logging-ok -d <your_domain>

Note: You need atleast certbot 0.22.0 to issue wildcard certificates.

Manually

• Put your inwx login data seperated by a newline into a file
• Create a txt record with letsencrypt-inwx create -c <credential_file> -d _acme-challenge.your-domain.com -v <acme_token>
• Delete it with letsencrypt-inwx delete -c <credential_file> -d _acme-challenge.your-domain.com
