I was in a similar situation a few months ago, I wanted to update my Route53 DNS and didn't want to trust the magic tool. I wrote my own simple script in Ruby using the letsencrypt gem and the AWS SDK. It might be a good starting place, feel free to fork and modify it for your own DNS provider. https://github.com/paul/letsencrypt-route53 https://github.com/paul/letsencrypt-route53
