dehydrated-nsupdate
===================
---------------------------------------
dehydrated hook for dns-01 verification
---------------------------------------
:manual section: 1
:manual group: Open Infrastructure
Synopsis
========
| **dehydrated-nsupdate**
Description
===========
**dehydrated** is a client for ACME-based Certificate Authorities, such as
LetsEncrypt. It can be used to request and obtain TLS certificates from an
ACME-based certificate authority.
The **dehydrated-nsupdate** hook implements the dns-01 verification. It is
typically run together with **dehydrated-hook** as:
| /etc/dehydrated/hook.d/deploy_challenge.nsupdate
| /etc/dehydrated/hook.d/clean_challenge.nsupdate
Features
========
**dehydrated-nsupdate** has the following features:
| **automatic nameserver detection**
| **dehydrated-nsupdate** automatically finds and updates all authoritative
| nameservers for a given record by looking up the records in the DNS by itself.
| **proper CNAME support**
| **dehydrated-nsupdate** follows CNAMEs delegating the TXT record creation to
| another zone.
| **handling nameserver subzone shortcuts**
| **dehydrated-nsupdate** correctly handles authoritative nameserver
| answers that give shortcut answers for their own zones when using
| multiple subzones.
| **TSIG support**
| **dehydrated-nsupdate** uses TSIG, if provided, to authenticate
| itself to the nameserver.
| **proper removal of TXT records**
| **dehydrated-nsupdate** removes records after succesfull verification.
| **bind9-dnsutils and knot-dnsutils support*
| **dehydrated-nsupdate** works with both nsupdate (bind9) and knsupdate (knot),
| including support for kdigs out-of-tree json output.
| **IDN handling**
| **dehydrated-nsupdate** works with IDN domains by not expanding the punycode.
Files
=====
The following files are used:
/etc/dehydrated/tsig.key:
default location for the TSIG key to be used.
/etc/default/dehydrated-nsupdate, /etc/default/dehydrated-nsupdate.d/*:
configuration file, currently only used for TSIG_KEYFILE variable pointing
to the tsig.key file to be used (default: /etc/dehydrated/tsig.key).
