This a hook for the Let's Encrypt ACME client dehydrated (formerly letsencrypt.sh), that enables using DNS records on dnsexit.com to respond to dns-01 challenges. It requires to have dig installed (sudo apt-get install dnsutils)

Hook Files

• base.sh (this is an utility file that is used by authorization.sh and cleanup.sh scripts)
• authorization.sh (this script add the dns text record to dnsexit and check that it was succesfully added)
• cleanup.sh (this script delete the created dns txt record)
• config.sh (this script is for setting the dnsExit.com access information)
  • dnsExitToken: Token provided by dns exit
  • dnsExitDomainList: List of possible base domains that you want to process

How to use it

• Update the config.sh with your dnsexit.com credentials
• Call the certbot command using the required parameters (renew example)
  • certbot renew --force-renew --break-my-certs --staging --agree-tos --email [email protected] --manual --preferred-challenges dns --manual-auth-hook ./authenticator.sh --manual-cleanup-hook ./cleanup.sh

How to test it

• There are two test script that will ask for your DNSExit credentials that will call the main scripts:
  • testAuthenticator.sh
  • testCleanup.sh
