INFO...As from fw 3.02.02, Letsencrypt is implemented in Thecus OS7 WebUI. This module can still be installed on OS7 but not needed.

Module is available for:

x64_OS5/OS7 - last version
x86_OS5/OS6 - last version
ppc_OS6 - last version

"You have not unlocked the download links. Read here to check how you can unlock them."

Python2 > 2.05.04
FaJoCron > 1.02.01
FaJoSSHD > 1.10.02 optional

Guides to use certificates on different modules, after they've been created:

apache and modules depending on apache -

Create SSL Certificate using Let’s Encrypt

SSH enabled on your NAS or FaJoSSHD module installed (NAS SSH will be used on this guide)
For PC, you need Putty or any SSH client to connect on you NAS
On your router forward port 80 and 443 to your NAS IP

A DNS which is pointed to your external IP, you can get one from and configure it on your NAS or router for automatic update, when you external IP changed. Then you can access your NAS remotely at or securely at

Enable HTTP and HTTPS service

Start Putty and connect on you NAS (HOST name select your NAS IP):

We consider in this tutorial your domain is or * for wildcard certificate

Type this command to add your domain, replace with your DNS

echo > /raid/data/MOD_CONFIG/letsencrypt/domain

or for wildcard certificate

echo * > /raid/data/MOD_CONFIG/letsencrypt/domain

Then type this command  to register:
/raid/data/module/Letsencrypt/shell/module.rc register

It will ask you for email address to register, type your email address and hit enter.

Saving debug log to /raid/data/MOD_CONFIG/letsencrypt/log/letsencrypt.log
Enter email address (used for urgent renewal and security notices) (Enter 'c' to

Would you be willing to share your email address with the Electronic Frontier

- Your account credentials have been saved in your Certbot
  configuration directory at /raid/data/MOD_CONFIG/letsencrypt. You
  should make a secure backup of this folder now. This configuration
  directory will also contain certificates and private keys obtained
  by Certbot so making regular backups of this folder is ideal.

Now let's create the certificates, enter the following command:

/raid/data/module/Letsencrypt/shell/module.rc certonly

or for wildcard certificate:

/raid/data/module/Letsencrypt/shell/module.rc certonly_dns_challenge

Certificates will be created and saved to /raid/data/MOD_CONFIG/letsencrypt/live/

Saving debug log to /raid/data/MOD_CONFIG/letsencrypt/log/letsencrypt.log

Non-standard path(s), might not work with crontab installed by your operating system package manager

- Congratulations! Your certificate and chain have been saved at
  Your cert will expire on 2017-07-30. To obtain a new or tweaked
  version of this certificate in the future, simply run certbot
  again. To non-interactively renew *all* of your certificates, run
  "certbot renew"

wildcard certificates have to be renewed manually using:
/raid/data/module/Letsencrypt/shell/module.rc renew_dns_challenge

For the standard certificate we need to setup a crontab job so that the certificates are checked for automatic renew twice a month. Due to the fact the renew process need access to port 80 and 443, Thecus WebUI is stoped and restarted after the check process.

Open FaJoCron WebUI and add the following line in crontab file:

PHP Code:
0 5 */15 * * root /raid/data/module/Letsencrypt/shell/module.rc renew 

Should look like below

Now we should configure Thecus WebUI to use our certificates. This is needed just once.
Copy the certificates from NAS somewhere locally on your PC. Certicates are stored to /raid/data/MOD_CONFIG/letsencrypt/archive/, so copy the folder somewhere on your PC.
Copy also  /raid/data/MOD_CONFIG/letsencrypt/live/ somewhere on your PC
You can use any client you want, WinSCP or modules like eXTPlorer or MonstaFTP. Folder contain the following files:

In Thecus WebUI go to Services >> Web Service >> Advanced
Certifcate file: select cert1.pem
Certificate Key file: select privkey1.pem
CA Certificate file: select ca-bundle.crt

Click apply and reboot your NAS
Enjoy secure connection
