[Script]Renew letsencrypt wildcard ssl cert for domain on name.com

[Script]Renew Wildcard Certificates with Letsencrypt for domain hosted by Name.com

This tutorial can renew your ssl certificate:

Wildcard certificates issued by letsencrypt.org need DNS TXT record to challenge, we can add TXT record manually when you apply the cert. If we want to automate it, we need to write a script that use the API of DNS provider to add TXT record. certbot has provided command argument --manual-auth-hook to pass the script.

1. Get a API token

Get your own api token provided by name.com: https://www.name.com/account/settings/api.
