+dehydrated cronjob for automatic certificate renewal
+----------------------------------------------------
+
+:manual section: 1
+:manual group: Open Infrastructure
+
+Synopsis
+========
+
+| **dehydrated-cron**
+
+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-cron** script runs dehydrated once per day and on system reboot for an automatic certificate renewal.
+
+It uses the dehydrated '--keep-going' option to keep going after encountering an error while creating/renewing multiple certificates. Afterwards it also removes all unused certificates by using the dehydrated '--cleanup-delete' option.
+
+Usage
+=====
+
+Installation
+------------
+
+| sudo ln -s /usr/bin/dehydrated-cron /etc/cron.d/dehydrated
+
+Removal
+-------
+
+| sudo rm -f /etc/cron.d/dehydrated
+
+
+Files
+=====
+
+The following files are used:
+
+/etc/cron.d/dehydrated:
+  cronjob file.
+
+/usr/bin/dehydrated-cron:
+  script that gets executed by cron.
+
+/var/log/dehydrated/dehydrated.log

+dehydrated run-parts hook
+-------------------------
+
+:manual section: 1
+:manual group: Open Infrastructure
+
+Synopsis
+========
+
+| **dehydrated-hook** 'HANDLER'
+
+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-hook** makes it possible to run multiple scripts in every stage within the process of creating, signing and deploying a certificate.
+
+Scripts need to be placed in /etc/dehydrated/hook.d and need to be prefixed with the name of the handler, e.g. exit_hook.example1 or exit_hook.example2.sh
+
+Handlers
+========
+
+The following **dehydrated** handlers are available:
+
+|
+| deploy_challenge
+| clean_challenge
+| sync_cert
+| deploy_cert
+| deploy_ocsp
+| unchanged_cert
+| invalid_challenge
+| request_failure
+| generate_csr
+| startup_hook
+| exit_hook
+
+Usage
+=====
+
+Installation
+------------
+
+| sudo echo HOOK="/usr/bin/dehydrated-hook" > /etc/dehydrated/conf.d/zz-hook.sh
+| sudo mkdir -p /etc/dehydrated/hook.d
+
+Removal
+-------
+
+| sudo rm -f /etc/dehydrated/conf.d/zz-hook.sh
+| sudo rmdir /etc/dehydrated/hook.d
+
+Files
+=====
+
+The following files are used:
+
+/etc/dehydrated/hook.d:
+  directory to place individual hooks.

+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 (IPv4 and IPv6)
+----------------------------------------------
+
+dehydrated-nsupdate automatically finds and updates all authoritative nameservers for a given record by looking up the records in the DNS by itself, supporting IPv6-only, IPv4-only, and dual-stacked environments.
+
+Proper CNAME support
+--------------------
+
+dehydrated-nsupdate follows CNAMEs delegating the TXT record update to another zone.
+
+Handling nameserver subzone shortcuts
+-------------------------------------
+
+dehydrated-nsupdate correctly handles authoritative nameserver answers that (wrongly) give shortcut answers for their own zones when using multiple authoritative subzones on the same nameservers.
+
+TSIG support
+------------
+
+dehydrated-nsupdate uses TSIG, if provided, to authenticate itself to the nameserver. Additionally to a global TSIG to be used for all record updates, separate TSIGs can individually be specified per record, per zone, and per 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).
+
+IDN handling
+------------
+
+dehydrated-nsupdate works with IDN domains by not expanding the punycode to update the correct records.
+
+Usage
+=====
+
+dehydrated-hook(1) is a prerequisite for dehydrated-nsupdate.
+
+Installation
+------------
+
+| sudo echo CHALLENGETYPE="dns-01" > /etc/dehydrated/conf.d/zz-challengetype.sh
+| sudo ln -s /usr/bin/dehydrated-nsupdate /etc/dehydrated/hook.d/deploy_challenge.nsupdate
+| sudo ln -s /usr/bin/dehydrated-nsupdate /etc/dehydrated/hook.d/clean_challenge.nsupdate
+
+Removal
+-------
+
+| sudo rm -f /etc/dehydrated/conf.d/zz-challengetype.sh
+| sudo rm -f /etc/dehydrated/hook.d/deploy_challenge.nsupdate
+| sudo rm -f /etc/dehydrated/hook.d/clean_challenge.nsupdate
+
+Configuration
+=============
+
+Depending on the nameserver requirements, dehydrated-nsupdate can send record updates either unauthenticated or using a TSIG (recommended).
+
+A TSIG file consists of one single line containing the key (nsupdate/knsupdate do not allow comments), e.g.:
+
+|
+| hmac-sha512:example:/LXPy6U8HAWA+QmvulZWm0owsQgNf8qJ5MNLTvirzvVtDb+PzLKoBmVHjnL6TUffkvRYa7Do448dSIrAuJ1G/A==
+
+Instead of using a global TSIG for all record update, specific TSIGs can be used individually per record, zone, and nameserver.
+
+The lookup hierarchy is the following (first match wins):
+
+|
+| /etc/dehydrated/tsig/${record}.key
+| /etc/dehydrated/tsig/${zone}.key
+| /etc/dehydrated/tsig/${nameserver}.key
+| /etc/dehydrated/tsig.key
+|
+| TSIG_KEYFILE variable in /etc/default/dehydrated-nsupdate/*
+| TSIG_KEYFILE variable in /etc/default/dehydrated-nsupdate
+
+In order to explicitly not use a TSIG for a specific record, zone, or nameserver, an empty keyfile or a keyfile with only comments can be used, e.g.:
+
+|
+| echo "# disabled" > /etc/dehydrated/tsig/ns1.example.org.key
+
+Files
+=====
+
+The following files are used:
+
+/etc/dehydrated/tsig.key:
+  default location for global TSIG key to be used.
+
+/etc/dehydrated/tsig/${record}.key, /etc/dehydrated/tsig/${zone}.key, /etc/dehydrated/tsig/${nameserver}.key:
+  default locations for specific TSIG keys to be used individually per record, zone, or nameserver.
+
+/etc/default/dehydrated-nsupdate, /etc/default/dehydrated-nsupdate.d/\*:
+  configuration file, currently only used for TSIG_KEYFILE variable pointing to the location of the global TSIG key to be used (default: /etc/dehydrated/tsig.key).
