NameSilo_Certbot-DNS-01

Hook script helpers for obtaining LetsEncrypt certificates, using Certbot with manual DNS-01 validation against NameSilo DNS.

Dependency

Make sure that you have xmllint installed on your system. On Ubuntu:

 $ apt-get install libxml2-utils

Example Setup

Add your NameSilo API key to at the top of config.sh and create a writable tmp folder in the directory that this file is in.

To make this the default setting for Certbot, add the following to your Certbot config at /etc/letsencrypt/cli.ini

server = https://acme-v02.api.letsencrypt.org/directory
authenticator = manual
preferred-challenges = dns-01
manual_auth_hook = /path/to/hook.sh
manual-cleanup-hook /path/to/cleanup.sh

Note: The server above must be set for DNS validation.

Another option is to just add the hook scripts along with any other options when calling Certbot like so:

$ certbot renew --manual-auth-hook /path/to/hook.sh --manual-cleanup-hook /path/to/cleanup.sh

Note: There is a 15 minute wait for DNS propagation.

Debug data will be printed in case of error response from NameSilo.
