Please keep in mind that this software and even the acme-protocol are relatively young and may still have some unresolved issues.
Feel free to report any issues you find with this script or contribute by submitting a pullrequest.
This script also supports the new `dns-01`-type verification. Be aware that at the moment this is not available on the production servers from letsencrypt. Please read `https://community.letsencrypt.org/t/dns-challenge-is-in-staging/8322` for the current state of `dns-01` support.
You need a hook script that deploys the challenge to your DNS server!
