- No longer require nginx or lighttpd for SLE
- Never go as far as to require acmeresponder, it might not be available
- Drop -update from dehydrated-update.{timer,socket} for consistency
- Add distro specific README.SUSE / README.Fedora
- Ran spec-cleaner

On Fedora, CentOS and RHEL, the dehydrated-apache2 package is
called dehydrated-httpd in accordance with the Fedora naming scheme.

==========================================
Acquiring TLS Certificates with Dehydrated
==========================================
The SUSE dehydrated package has been designed to make acquiring TLS
certificates (aka SSL Certificates) as simple as possible, while still being
useful in a broad amount of use cases. Please consult the dehydrated man page,
then continue reading here.
Aqcuisition through HTTP (http-01)
===================================
This is the primary method of acquiring certifictes.
Setting up the acme-challenge auto-responder
--------------------------------------------
Apache
~~~~~~
If you are using Apache, just install dehydrated-apache2 and reload Apache.
This will take care of setting up the acme-challenge auto-responder.
nginx
~~~~~
(not part of SLE, use openSUSE backports)
For nginx, you will need to install dehydrated-nginx. Unfortunately, nginx does
not support directory mappings across vhosts, so in addition you will need to
include "/etc/nginx/acmechallenge" in all vhost configurations like this:
server {
listen 80;
listen [::]:80;
server_name <hostname>;
include "acmechallenge";
location / {
return 301 https://$host$request_uri;
}
}
lighttpd
~~~~~~~~
(not part of SLE, use openSUSE backports)
Lighttpd users can simply install dehydrated-lighttpd and reload lighttpd to
set up the acme-challenge auto-responder
NOTE: Never set up the SSL vhosts until you have initially acquired the first
host. Specifying an SSL vhost without certificates constitutes an error for web
servers.
Machines without a webserver
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
On machines that are not running any web server, e.g. mail relays, you can run
apache2 with dehydrated-apache2. If you do not want to run any web server on a
system with systemd, you can use dehydrated-acmeresponder, a small socket
activated server. Once installed, it will automatically listen on port 80
whenever the dehydrated cron job seeks renewal, assuming no other server is
currently occupying the port. It will also shut down once the timer has
finished execution.
Acquisition of initial certificate
----------------------------------
How set up an account as described in the man page (as root):
# dehydrated --register --accept-terms
(the current version of the LetsEncrypt Terms & Conditions are referenced in
/etc/dehydrated/config)
Next, fill in domains.txt and acquire the initial certificates (again, as root):
# echo "myhost.example.com myalias.example.com" >> domains.txt
# dehydrated --cron
adds myhost.example.com to the list of host names we want to request a certificate for.
The certificate will hold a Subject Alternative Name of "myalias.example.com".
LetsEncrypt will check both host names.
NOTE: As of 2017, LetsEncrypt certificates are only valid for three months, and
the validity period may be further reduced in the future. It is therefore
vital to ensure that the certificates are being automatically renewed. On
systems without systemd, a cron job is automatically set up to take care of
this. On systemd-enabled systems, a timer is provided which needs to be
activated manually:
# systemctl enable dehydrated.timer
Aqcuisition through DNS (dns-01)
================================
Tnis is mostly useful under these conditions
1. Your hosts are not directly exposed to the internet
2. Your host names are part of a public DNS zone visible on the internet.
3. You are comfortable with the service adding and removing records in your domain.
Usually, the scenario you want this is a central host which picks up
certificates for all other hosts on a network, and then deploys them to the
actual target host, using plain scp or configuration management tools like
Ansible or Salt. For details, please refer to dns-verification.md. For
openSUSE, the python-dns-lexicon package provides hooks into many DNS providers
and DNS servers.
Proceeding After initial certificate Aquisition
===============================================
Setting up the SSL host
-----------------------
As recommended parameters shift, please refer to Mozillas excellent SSL
Configuration Generator [1] for details on how to configure your web server.
Replace the example paths with the following:
Key: /etc/dehydrated/certs/<domainname>/privkey.pem
Certificate: /etc/dehydrated/certs/<domainname>/cert.pem
Intermediate Chain: /etc/dehydrated/certs/<domainname>/chain.pem
Certificate + Intermediate: /etc/dehydrated/certs/<domainname>/fullchain.pem
where <domainname> should be the name of the first column in domains.txt
Limitations & Ceveats
=====================
* It is currently not possible to aqcuire Wildcard certificates
* No EV- or OV-validated certificates
* Certificates expire within weeks, not years, this is by design. Ensure that
certificate renewal works and that daemons get reloaded frequently to pick
up certificate updates (This is currently not automated on the dehydrated end,
however Apache will reload every night due to log rotation).
