{{warning box| The original protocol used by Let’s Encrypt for certificate issuance and management is called ACMEv1. In March of 2018 Letsencrypt introduced support for ACMEv2, a newer version of the protocol that matches what was finalized today as RFC 8555 328. They have been encouraging subscribers to move to the ACMEv2 protocol.
 +
 
 +
In March 2019 they announced an end of life plan for ACMEv1.
 +
 
 +
In November of 2019 they will stop allowing new account registrations through their ACMEv1 API endpoint. '''IMPORTANTLY''' Existing accounts will continue to function normally.
 +
 
 +
In June of 2020 they will stop allowing new domains to validate via ACMEv1.
 +
 
 +
Starting at the beginning of 2021 they will occasionally disable ACMEv1 issuance and renewal for periods of 24 hours, no more than once per month (OCSP service will not be affected). The intention is to induce client errors that might encourage subscribers to update to clients or configurations that use ACMEv2.
 +
 
 +
Renewal failures should be limited since new domain validations will already be disabled and we recommend renewing certificates 30 days before they expire.
 +
 
 +
In June of 2021 they will entirely disable ACMEv1 as a viable way to get a Let’s Encrypt certificate.}}

As of December 2015, the Letsencrypt service is in a public beta state.  They issue valid, trusted certificates, but the client code (and, to a lesser extent, the server code) is likely in a state of flux.  At least during the initial stages of the public beta, they're implementing rate-limiting, allowing no more than five certificates per domain in a rolling seven-day period.  This may make them unsuitable for users of dynamic DNS services.  The latest information about rate limiting should be posted on [https://letsencrypt.org/docs/rate-limits/ this page] of the letsencrypt.org documentation.  As of March 26, 2016, the rate limit has been increased to 20 certificates per domain per week.

If you're going to be testing things in ways that would involve requesting lots of certificates in a short period of time, you're encouraged to use the Letsencrypt staging CA for this purpose.  Certificates generated by this CA will not be trusted by your browser, and will appear to be issued by the "Happy hacker CA", but it will allow you to validate the toolchain and workflow.

Multiple clients are available for the Letsencrypt services.  The official "certbot" client from letsencrypt.org is quite full-featured, but has a number of dependencies that it needs to install.  It also requires a newer version of Python than is included with a standard SME Server installation.  Due to this complexity, and the lack of compatibility with SME 8.x, this document describes installation and use of ''[https://github.com/lukas2511/dehydrated dehydrated]'', an alternative client implemented as a BASH shell script.

You can also set this contrib to obtain a certificate for all domains, all hostnames, or all domains AND hostnames.

You can obtain a certificate for either of the following: all domains, all hostnames, or all domains AND hostnames. Only set one of the following.
−
config setprop letsencrypt configure all | domains | hosts
 
  
−
With the system configuration described above, setting this to "domains" will obtain a certificate covering domain1.com and domain2.com, but not www.domain1.com, etc.  Setting it to "hosts" will obtain a certificate covering www.domain1.com, mail.domain1.com, ftp.domain1.com, etc., but not domain1.com or domain2.com.  Setting this property to "all" will include all domain names and hostnames in the certificate.
+
config setprop letsencrypt configure domains
  
−
====Other configuration properties====
+
  config setprop letsencrypt configure hosts
−
No other settings are mandatory.  However, it's recommended to configure an email address.  If there should be a problem with renewing your certificate, and it comes close to expiring, the Let's Encrypt servers will notify you of this.  Do so with this command:
 
−
  config setprop letsencrypt email admin@domain1.com
 
  
−
The email domain specified here doesn't need to match any of the domains you're obtaining a cert for.
+
config setprop letsencrypt configure all
  
−
You can also set the length of your certificate's private key, if you don't want the default of 4096 bits. This should not be necessary in most cases, but if desired, use this command to do so:
+
To use individually enabled hosts or domains leave the default none.
−
config setprop letsencrypt keysize NUMBER
 
  
−
===Accept Let's Encrypt terms ===
+
  config setprop letsencrypt configure none
−
Please first read the condition terms for using Let's Encrypt [[https://letsencrypt.org/documents/LE-SA-v1.1.1-August-1-2016.pdf]]
 
−
  config setprop letsencrypt ACCEPT_TERMS yes
 
  
−
===Enable Test Mode===
+
 
−
The next step is to enable test mode.  This will obtain certificates from the staging server.  The rate limits discussed in the introduction won't apply, so any errors or other issues won't prevent you from obtaining your production certificate.  Enable test mode using this command:
+
With the system configuration described above, setting this to "domains" will obtain a certificate covering domain1.com and domain2.com, but not www.domain1.com, etc.  Setting it to "hosts" will obtain a certificate covering www.domain1.com, mail.domain1.com, ftp.domain1.com, etc., but not domain1.com or domain2.com.  Setting this property to "all" will include all domain names and hostnames in the certificate. '''See [[Letsencrypt/Troubleshooting#Some_challenges_complete_successfully_but_some_hostnames_fail|NOTE]] before setting this to "all".'''
 +
 
 +
==== Enable test mode ====
 +
After installing and configuring all the domains and hosts, the next step is to use test mode, which is enabled by default.  This will obtain certificates from the staging server.  The rate limits discussed in the introduction won't apply, so any errors or other issues won't prevent you from obtaining your production certificate.  Enable test mode using this command:
 
  config setprop letsencrypt status test

==Manual Installation of Dehydrated==
 
−
As discussed above, dehydrated is a lightweight ACME client that's implemented as a BASH script.  It has very few dependencies, and is a better fit for the "SME way" of doing things than the official certbot client.  If you'd prefer to configure it manually, rather than installing the contrib described above, you may do so manually or by pulling a copy of the latest version using git.
 
−
 
 
−
===Contrib install of Dehydrated===
 
−
The dehydrated script has been imported into the contribs repository and can be installed as follows:
 
−
 
 
−
yum --enablerepo=smecontribs install dehydrated
 
−
 
 
−
The script must be configured as described below.
 
−
 
 
−
===Git install of latest version===
 
−
 
 
−
If you need or want the absolute latest version of the script then you can manually install as follows:
 
−
 
 
−
Begin by installing git:
 
−
yum install git
 
−
 
 
−
Then download the Dehydrated client:
 
−
cd /etc
 
−
git clone https://github.com/lukas2511/dehydrated
 
−
mv dehydrated/dehydrated /usr/local/bin/
 
−
 
 
−
===Manual Configuration of Dehydrated===
 
−
 
 
−
You'll need to create two configuration files for Dehydrated.
 
−
cd /etc/dehydrated
 
−
mkdir -p /home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge
 
−
nano -w domains.txt
 
−
 
 
−
In this file, you'll list every hostname that you want your certificate to cover, all on one line.  It will look like this:
 
−
domain1.com www.domain1.com mail.domain1.com domain2.net www.domain2.net domain3.org ftp.domain3.org
 
−
Ctrl-X to exit, Y to save.
 
−
 
 
−
Second, you'll need to create the configuration file '''config''':
 
−
nano -w config
 
−
 
 
−
It should look like this:
 
−
#!/bin/bash
 
−
# config
 
−
# CA="https://acme-staging.api.letsencrypt.org/directory"
 
−
WELLKNOWN="/home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge"
 
−
HOOK="/usr/local/bin/dehydrated-hook"
 
−
# E-mail to use during the registration (default: <unset>)
 
−
CONTACT_EMAIL="admin@yourdomain.com"
 
−
 
 
−
Ctrl-X to exit, Y to save.
 
−
 
 
−
For testing purposes, it's recommended that you uncomment the third line (so it begins with "CA=").  Any certificates issued while testing will not be trusted, but they will also not count against your rate limits.  Once your configuration is set, you can comment out that line and re-run dehydrated.
 
−
 
 
−
You'll need to create a custom "hook" script to set the config database up properly, and to trigger reloads of your system services when a certificate is issued or renewed.
 
−
nano /usr/local/bin/dehydrated-hook
 
−
 
 
−
Its contents should look like this:
 
−
#!/bin/bash
 
−
 
−
if [ $1 = "deploy_cert" ]; then
 
−
  KEY=$3
 
−
  CERT=$4
 
−
  CHAIN=$6
 
−
  /sbin/e-smith/db configuration setprop modSSL key $KEY
 
−
  /sbin/e-smith/db configuration setprop modSSL crt $CERT
 
−
  /sbin/e-smith/db configuration setprop modSSL CertificateChainFile $CHAIN
 
−
  /sbin/e-smith/signal-event ssl-update
 
−
fi
 
−
 
 
−
Ctrl-X to exit, Y to save.  Then make it executable:
 
−
chmod +x /usr/local/bin/dehydrated-hook
 
  
−
You'll also need to create a custom template fragment for Apache:
+
A new function lets you cleanup old and archive old certificates.
−
mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf
 
−
nano -w /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/VirtualHosts40ACME
 
  
−
The contents of that file should look like:
+
  dehydrated --cleanup (-gc)
−
  # Alias for letsencrypt
 
−
Alias /.well-known/acme-challenge /home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge
 
−
Again, Ctrl-X to exit, Y to save.
 
  
−
Expand the template and restart apache:
+
===Configuration properties===
−
expand-template /etc/httpd/conf/httpd.conf
+
{| class="wikitable"
−
service httpd-e-smith restart
+
!Key
−
 
+
!property
−
Now you're ready to run dehydrated and get your certificate.
+
!default
−
dehydrated -c
+
!values
−
 
+
!
−
The script will run for a moment and should report success.  If it does, look in /etc/dehydrated/certs/YOURDOMAIN and see if you have your files there.  You should see a number of .pem files, at least one .csr file, and five symbolic links (chain.pem, cert.csr, cert.pem, fullchain.pem, and privkey.pem).  If you do, congratulations!  You've successfully obtained your certificate.  The hook script should have also configured your server to use the new certificate. To make sure, run
+
|-
−
config show modSSL
+
| rowspan="10" |letsencrypt
−
and make sure there are values set for crt, key, and CertificateChainFile.
+
|ACCEPT_TERMS
−
 
+
|
−
If dehydrated ran successfully in test mode, comment out the CA= line in /etc/dehydrated/config and run
+
|empty, yes
−
dehydrated -c -x
+
|set to yes to accept terms of service, if left empty the contrib will not work.
−
 
+
|-
−
to obtain trusted a trusted certificate.
+
|API
−
 
+
|2
−
===Renewal===
+
|1,2
−
When run, the dehydrated script will check your existing certificate to see how long it's valid.  If it has less than 30 days' lifetime remaining (by default; this can be changed by setting RENEW_DAYS in config to something other than 30), the script will renew your certificates.  If more than 30 days remain, the script will exit without further action. All that's necessary is to run dehydrated daily:
+
|deprecated, will always be v2, as v1 is deprecated as per june 2021
−
nano -w /etc/cron.daily/call-dehydrated
+
|-
−
 
+
|configure
−
Enter the following in this file:
+
|none
−
#!/bin/bash
+
|none,all,domains,hosts
−
/usr/local/bin/dehydrated -c

|this will change the default behaviour on non explicitly domains or hosts with "letsencryptSSLcert enabled". By default will not be used, if hosts is set will ask a cert for all hosts, if domains is set will ask a cert for all domains, if all is set, will ask for both domains and hosts. In all situation it will ask a cert for domains/hosts where "letsencryptSSLcert enabled" is set and it is not set to "letsencryptSSLcert disabled"

===Certificate Errors===
+
see [[Letsencrypt/Troubleshooting]]
−
Errors in the certificate files may prevent Apache and some other services from starting.  If you previously had custom settings for modSSL, revert those with:
 
−
config setprop modSSL crt (old value)
 
−
config setprop modSSL key (old value)
 
−
config setprop modSSL CertificateChainFile (old value--if this property was empty, delete it using the command line below)
 
−
 
 
−
If you did not have custom settings for modSSL, remove your changes with:
 
−
config delprop modSSL crt
 
−
config delprop modSSL key
 
−
config delprop modSSL CertificateChainFile
 
−
 
 
−
Once you've made these changes, do:
 
−
signal-event post-upgrade
 
−
signal-event reboot
 
−
 
 
−
===Authorization Errors===
 
−
The first thing is to check all your domains can resolve
 
−
 
 
−
http://my.domain/.well-known/acme-challenge
 
−
 
 
−
Check that the following files are correctly generated
 
−
 
 
−
/etc/dehydrated/config
 
−
/etc/dehydrated/domains.txt
 
−
 
 
−
Set letsencrypt back to test and remove any generated keys
 
−
 
 
−
db configuration setprop letsencrypt status test
 
−
 
 
−
rm /etc/dehydrated/certs/* -rf
 
−
rm /etc/dehydrated/accounts/* -rf
 
−
 
 
−
Then run letsencrypt again
 
−
 
 
−
dehydrated -c
 
−
 
 
−
To restore the original certificates:
 
−
 
 
−
config delprop modSSL CertificateChainFile
 
−
config delprop modSSL crt
 
−
config delprop modSSL key
 
−
 
 
−
signal-event console-save
 
−
 
 
−
===Errors===
 
−

===Obtaining certificates for other servers===
 
−
The dehydrated client can be used to obtain certificates for other servers on your network, if the hostnames resolve (from outside your network) to your SME Server.  Here's how to do this using John Crisp's contrib.
 
−
 
 
−
You'll need to create two template fragments: one to add your hostname to /etc/dehydrated/domains.txt, and the second to handle the certificate once it's generated.  To create the first, do
 
−
 
 
−
mkdir -p /etc/e-smith/templates-custom/etc/dehydrated/domains.txt
 
−
nano -w /etc/e-smith/templates-custom/etc/dehydrated/domains.txt/15Hostname
 
−
 
 
−
You can replace "Hostname" in "15Hostname" with something that's descriptive of the host you're obtaining a certificate for.  If you want more than one additional certificate, create separate fragments for each one.  In the file, just enter the fully-qualified domain name of the system:
 
−
 
 
−
hostname.domain.tld
 
−
 
 
−
Then Ctrl-X to exit, Y to save.
 
−
 
 
−
The second template fragment will be a portion of the hook script, so the dehydrated client knows what to do with this certificate.  This must be present, otherwise dehydrated will configure your SME server to use this certificate rather than the certificate for the SME Server.
 
−
 
 
−
mkdir -p /etc/e-smith/templates-custom/usr/local/bin/hook-script.sh/
 
−
nano -w 05deploy_cert_hostname
 
−
 
 
−
As above, replace "hostname" with something that describes the host that this script will apply to.  The numeric portion can be changed, but MUST be less than 10.
 
−
 
 
−
At a minimum, this fragment will need to recognize that it's being called for a certificate other than the main server certificate, and exit in order to prevent later portions of the script from installing that certificate as the main server certificate.  The minimal form of this fragment would be:
 
−
 
 
−
{
 
−
    use strict;
 
−
    use warnings;
 
−
    use esmith::ConfigDB;
 
−
 
−
    my $configDB = esmith::ConfigDB->open_ro or die("can't open Config DB");
 
−
 
−
    my $letsencryptStatus = $configDB->get_prop( 'letsencrypt', 'status' )    || 'disabled';
 
−
 
−
    if ( $letsencryptStatus ne 'disabled' ) {
 
−
 
−
    $OUT .=<<'_EOF';
 
−
if [ $1 = "deploy_cert" ] && [ $2 = "hostname.domain.tld" ]; then
 
−
  echo "$2 certificate renewed" | mail -s "Certificate renewal" admin@yourdomain.com
 
−
  exit 0
 
−
fi
 
−
_EOF
 
−
 
−
    }
 
−
}
 
−
 
 
−
Depending on the characteristics of the other system, though, this script may be able to install the certificate on that system.  The following fragment would copy the certificate files to a remote Linux system running Apache for the web server, and reload Apache to get it to begin using the new certificate:
 
−
 
 
−
{
 
−
    use strict;
 
−
    use warnings;
 
−
    use esmith::ConfigDB;
 
−
 
−
    my $configDB = esmith::ConfigDB->open_ro or die("can't open Config DB");
 
−
 
−
    my $letsencryptStatus = $configDB->get_prop( 'letsencrypt', 'status' )    || 'disabled';
 
−
 
−
    if ( $letsencryptStatus ne 'disabled' ) {
 
−
 
−
    $OUT .=<<'_EOF';
 
−
if [ $1 = "deploy_cert" ] && [ $2 = "hostname.domain.tld" ]; then
 
−
  KEY=$3
 
−
  CERT=$4
 
−
  CHAIN=$6
 
−
  scp $CERT root@hostname:/etc/pki/tls/certs/pbx.familybrown.org.crt
 
−
  scp $KEY root@hostname:/etc/pki/tls/private/pbx.familybrown.org.key
 
−
  scp $CHAIN root@hostname:/etc/pki/tls/certs/server-chain.crt
 
−
  ssh root@pbx "/sbin/service httpd reload"
 
−
  echo "$2 certificate renewed" | mail -s "Certificate renewal" admin@domain.tld
 
−
  exit 0
 
−
fi
 
−
_EOF
 
−
 
−
    }
 
−
}
 
−
 
 
−
The following fragment would install the new certificate on a Proxmox VE host:
 
−
 
 
−
{
 
−
    use strict;
 
−
    use warnings;
 
−
    use esmith::ConfigDB;
 
−
 
−
    my $configDB = esmith::ConfigDB->open_ro or die("can't open Config DB");
 
−
 
−
    my $letsencryptStatus = $configDB->get_prop( 'letsencrypt', 'status' )    || 'disabled';
 
−
 
−
    if ( $letsencryptStatus ne 'disabled' ) {
 
−
 
−
    $OUT .=<<'_EOF';
 
−
if [ $1 = "deploy_cert" ] && [ $2 = "pve.domain.tld" ]; then
 
−
  KEY=$3
 
−
  CHAIN=$5
 
−
  scp $KEY root@pve:/etc/pve/nodes/pve/pveproxy-ssl.key
 
−
  scp $CHAIN root@pve:/etc/pve/nodes/pve/pveproxy-ssl.pem
 
−
  ssh root@pve "systemctl restart pveproxy"
 
−
  echo "$2 certificate renewed" | mail -s "Certificate renewal" admin@domain.tld
 
−
  exit 0
 
−
fi
 
−
_EOF
 
−
 
−
    }
 
−
}
 
−
 
 
−
Once you've created the template fragments, expand the templates and run dehydrated to generate the certificates:
 
−
signal-event console-save
 
−
dehydrated -c
 
  
−
These certificates will be automatically renewed, just like the main server certificate.

Description

Warning.png Warning:
The original protocol used by Let’s Encrypt for certificate issuance and management is called ACMEv1. In March of 2018 Letsencrypt introduced support for ACMEv2, a newer version of the protocol that matches what was finalized today as RFC 8555 328. They have been encouraging subscribers to move to the ACMEv2 protocol.

In March 2019 they announced an end of life plan for ACMEv1.

In November of 2019 they will stop allowing new account registrations through their ACMEv1 API endpoint. IMPORTANTLY Existing accounts will continue to function normally.

In June of 2020 they will stop allowing new domains to validate via ACMEv1.

Starting at the beginning of 2021 they will occasionally disable ACMEv1 issuance and renewal for periods of 24 hours, no more than once per month (OCSP service will not be affected). The intention is to induce client errors that might encourage subscribers to update to clients or configurations that use ACMEv2.

Renewal failures should be limited since new domain validations will already be disabled and we recommend renewing certificates 30 days before they expire.

In June of 2021 they will entirely disable ACMEv1 as a viable way to get a Let’s Encrypt certificate.


Let’s Encrypt is a new Certificate Authority: It’s free, automated, and open. Its main purpose is to allow people to encrypt their internet traffic at no cost, easily, and automatically. The certs delivered must be renewed every 3 months.

As of December 2015, the Letsencrypt service is in a public beta state. They issue valid, trusted certificates, but the client code (and, to a lesser extent, the server code) is likely in a state of flux. At least during the initial stages of the public beta, they're implementing rate-limiting, allowing no more than five certificates per domain in a rolling seven-day period. This may make them unsuitable for users of dynamic DNS services. The latest information about rate limiting should be posted on this page of the letsencrypt.org documentation. As of March 26, 2016, the rate limit has been increased to 20 certificates per domain per week.

If you're going to be testing things in ways that would involve requesting lots of certificates in a short period of time, you're encouraged to use the Letsencrypt staging CA for this purpose. Certificates generated by this CA will not be trusted by your browser, and will appear to be issued by the "Fake LE Intermediate X1", but it will allow you to validate the toolchain and workflow.

The current status of the Letsencrypt services can be found on their status page.

Multiple clients are available for the Letsencrypt services. The official "certbot" client from letsencrypt.org is quite full-featured, but has a number of dependencies that it needs to install. It also requires a newer version of Python than is included with a standard SME Server installation. Due to this complexity, and the lack of compatibility with SME 8.x, this document describes installation and use of dehydrated, an alternative client implemented as a BASH shell script.

Prerequisites

The Letsencrypt client and server interact to confirm that the person requesting a certificate for a hostname actually controls that host. For this reason, there are some prerequisites for your configuration. For example, if you're trying to obtain a certificate for www.example.com, the following conditions must be met:

  • www.example.com is a valid domain name--the domain has been registered, and DNS records are published for it.
  • www.example.com resolves to your SME Server--published DNS records give the external IP address of your SME Server when queried for www.example.com.
  • Your SME Server is connected to the Internet, and is able to make outbound connections on ports 80 and 443.
  • Port 80 on your SME Server is open to the Internet (i.e., the Internet can reach your server on port 80)--you aren't behind a firewall, or some ISP filtering, that would block it. If you've made SSL mandatory for the Primary ibay, port 443 must also be open.

Letsencrypt will issue certificates that include multiple hostnames (for example, www.example.com, example.com, and mail.example.com), all of which would be part of the request. All of the conditions above must be true for all of the hostnames you want to include in the certificate.

Make sure you've got this all set up correctly before continuing.

Preparation

Before you begin installation, check to see if you or an installed contrib have configured any custom values for your TLS/SSL certificate: 

# config show modSSL

By default it would show: 

modSSL=service
   TCPPort=443
   access=public
   status=enabled

If this shows any values for crt, key, or CertificateChainFile, make a note of them. If you encounter an issue with the certificate files generated by Letsencrypt, you'll then be able to revert your changes. To make a 'backup' of your existing key and properties you can issue: 

config show modSSL > "/root/db_configuration_modSSL_backup_$(date +%Y%m%d_%H%M%S)"

Installation of Dehydrated letsencrypt contrib

John Crisp has prepared a contrib that installs the dehydrated script, creates the appropriate configuration files, and integrates with the SME templates system. This is the simplest way to install dehydrated on your SME Server. 

yum install smeserver-letsencrypt

You will then need to configure the domains and hosts for which you want to ask a certificate. See the following Configuration section.

If your smeaddons repo has been disabled add --enablerepo=smeaddons and reenable it, as it should be by default. 

db yum_repositories setprop smeaddons status enabled
signal-event yum-modify

Installation

yum install smeserver-letsencrypt
signal-event console-save

You will then need to configure the domains and hosts for which you want to ask a certificate. See the following Configuration section.

If your smeaddons repo has been disabled add --enablerepo=smeaddons and reenable it, as it should be by default. 

db yum_repositories setprop smeaddons status enabled
signal-event yum-modify

Updating

Few reported issue when upgrading the contribs see Bugzilla:10286 and Bugzilla:10097

A full update can be done as follow : 

yum update smeserver-letsencrypt dehydrated
config setprop letsencrypt ACCEPT_TERMS yes
signal-event console-save

failure to do this might leave the contribution not working and your certificates not renewed.

Configuration

There are several configuration database entries that need to be made in order to set up this contrib. Most of them tell the scripts which hostnames need to be part of your certificate.

Rush jobs

For the test (adjust the domains and hosts): 

config setprop letsencrypt ACCEPT_TERMS yes status test
# really fast job to enable the primary domain
db domains setprop $(config get DomainName) letsencryptSSLcert enabled
#foreach of your domains you want SSL do the following
db domains setprop domain1.com letsencryptSSLcert enabled
#foreach of your hosts (subdomains) you want SSL do the following
db hosts setprop www.domain1.com letsencryptSSLcert enabled
signal-event smeserver-letsencrypt-update
dehydrated -c

config setprop letsencrypt ACCEPT_TERMS yes status test API 2
#foreach of your domains you want SSL do the following
db domains setprop domain1.com letsencryptSSLcert enabled
#foreach of your hosts (subdomains) you want SSL do the following
db hosts setprop www.domain1.com letsencryptSSLcert enabled
signal-event console-save
dehydrated -c

Check that the certificates are available ( your browser will still issue an error, but you can explore the content of the certificate to see that the Let's Encrypt test CA was used to sign your SSL certificate and that all your domains and hosts are in the "Certificate Subject Alt Name" property.

For the production (adjust your email): 

config setprop letsencrypt status enabled email admin@$(config get DomainName)
signal-event smeserver-letsencrypt-update
dehydrated -c -x

config setprop letsencrypt status enabled email admin@domain1.com
signal-event console-save
dehydrated -c -x

Step by step configuration

Hosts and domains for the certificate

This contrib will obtain a single certificate from Let's Encrypt. The certificate will include all the domains and hostnames that:

  • Are configured on your SME Server (e.g., through the Server Manager), and
  • Are configured to use Let's Encrypt.

For example, your SME Server may contain the following domains and hostnames:

  • domain1.com
    • www.domain1.com
    • mail.domain1.com
    • ftp.domain1.com
  • domain2.com
    • www.domain2.com
    • mail.domain2.com

For each DOMAIN that you want to be included in the certificate, run this command: 

db domains setprop $DOMAIN letsencryptSSLcert enabled

Using the above example, one invocation of the command would look like this: 

db domains setprop domain1.com  letsencryptSSLcert enabled

For each HOSTNAME that you want to be included in the certificate, run this command: 

db hosts setprop $HOSTNAME letsencryptSSLcert enabled

Using the above example, one invocation of the command would look like this: 

db hosts setprop www.domain1.com letsencryptSSLcert enabled

You can obtain a certificate for either of the following: all domains, all hostnames, or all domains AND hostnames. Only set one of the following. 

config setprop letsencrypt configure domains

config setprop letsencrypt configure hosts

config setprop letsencrypt configure all

To use individually enabled hosts or domains leave the default none. 

config setprop letsencrypt configure none


With the system configuration described above, setting this to "domains" will obtain a certificate covering domain1.com and domain2.com, but not www.domain1.com, etc. Setting it to "hosts" will obtain a certificate covering www.domain1.com, mail.domain1.com, ftp.domain1.com, etc., but not domain1.com or domain2.com. Setting this property to "all" will include all domain names and hostnames in the certificate. See NOTE before setting this to "all".

Enable test mode

After installing and configuring all the domains and hosts, the next step is to use test mode, which is enabled by default. This will obtain certificates from the staging server. The rate limits discussed in the introduction won't apply, so any errors or other issues won't prevent you from obtaining your production certificate. Enable test mode using this command: 

config setprop letsencrypt status test
signal-event console-save

You can now run dehydrated for the first time, and make sure it's able to connect to the Let's Encrypt servers, validate the hostnames you're requesting, and issue certificates. To do this, run 

dehydrated -c

If it prints only "# INFO: Using main config file /etc/dehydrated/config" and returns you to the shell prompt, see Bugzilla:10300.


Important.png Note:
Solution for error "Malformed account ID in KeyID header URL" using API 2, for contrib versions 0.6.13 or older See Bugzilla:10828 or update to latest contrib


If this runs without errors, try to connect to your server-manager page. You should see an error that the security certificate wasn't issued by a trusted certification authority; this is perfectly normal. However, there should be a certificate, it should include all the hostnames you wanted included, and it should be valid for the next ninety days. If this was successful, proceed to production.

Enable Production Mode

Once you've successfully tested your installation, set it to production mode using these commands: 

config setprop letsencrypt status enabled
signal-event console-save

Then obtain a new certificate from the Let's Encrypt production server: 

dehydrated -c -x

The -x flag here is needed to force dehydrated to obtain a new certificate, even though you have an existing certificate that's valid for more than 30 days.

If this command succeeded, congratulations! You've successfully obtained a valid, trusted TLS certificate, which will automatically renew itself in perpetuity.

Once you've obtained your certificate and configured your server, test your server with a tool like SSLLabs.com to make sure it's working properly.

Archive old certificates

A new function lets you cleanup old and archive old certificates. 

dehydrated --cleanup (-gc)

Configuration properties

Key property default values
letsencrypt ACCEPT_TERMS empty, yes set to yes to accept terms of service, if left empty the contrib will not work.
API 2 1,2 deprecated, will always be v2, as v1 is deprecated as per june 2021
configure none none,all,domains,hosts this will change the default behaviour on non explicitly domains or hosts with "letsencryptSSLcert enabled". By default will not be used, if hosts is set will ask a cert for all hosts, if domains is set will ask a cert for all domains, if all is set, will ask for both domains and hosts. In all situation it will ask a cert for domains/hosts where "letsencryptSSLcert enabled" is set and it is not set to "letsencryptSSLcert disabled"
email email enter the email to create account and receive updates from Let's Encrypt
hookScript disabled enabled,disabled will trigger advanced hook script if enabled, even if disabled the part to signal-event ssl-update to propagate the cert will run.
hostOverride disabled yes,disabled default disabled, if disabled will only ask cert for hosts (if selected according to configure and "letsencryptSSLcert enabled") for hosts with type=Self. If set to yes will include any listed hosts whether remote or local.
keysize 4096 base 2 number length of your certificate's private key, if you don't want the default of 4096 bits. This should not be necessary in most cases, but if desired, use this command to do so:
status test enabled,disabled,test default status is disabled, First set it to test to connect to the test server of let's Encrypt to check if your server is well configured. After checking everything is ok, you can set it to enabled.
