NameSilo Let's Encrypt

Python scripts (hook) to automate obtaining Let's Encrypt certificates, using Certbot DNS-01 challenge validation for domains DNS hosted on NameSilo.

Setup

The scripts use the untangle and tldextract libraries, if not already installed on your system:

pip install untangle

pip install tldextract

Download the latest release archive and expand it in the desired directory.

Configuration

Add your NameSilo API key to the top of the config.py file:

# Get your API Key from: https://www.namesilo.com/account_api.php
apikey = "YOUR_API_KEY"

Alternatively, the API key can be set in the NAMESILO_API environment variable.

Using with Certbot

To issue or renew a certificate using the hook scripts, try something like:

certbot certonly --manual --email you@example.com \
--agree-tos --manual-public-ip-logging-ok \
--preferred-challenges=dns \
--manual-auth-hook /path/to/authenticator.py \
--manual-cleanup-hook /path/to/cleanup.py \
-d *.example.com -d example.com

Please note that NameSilo DNS propagation takes up to 15 minutes. The scripts will wait 20 minutes before completing, just to be safe. q
