Hello Dandy010,

Your information is in red.
I needed to renew the certificate anyway, so for those who would like to have a *FREE* certificate for their NAS (and not 90 days free, but always):
Create an account on http://www.startssl.com and export the authentication certificate (to logon to the website) as per their instructions
Validate an e-mail address
Validate the domain you're using (create a postmaster account or an alias) to do the verification (use check e-mail address from the startssl.com toolbox)
Then request the server certificate:
- Remember (or better: write down) your password, select 2048 bits and SHA2
- Select http://www. domain.ext> (or whatever you use)
- Save the private RSA key as ssl.key
- Save the certificate as ssl.crt
- Decrypt the private key (ssl.key) to ssl.decrypted
- Create a new text file and copy the contents of both ssl.decrypted and ssl.crt (in that order) into this file
- Save the new file and import this file a a certificate in your NAS (no need to worry about intermediate or root certificates)
Test your https connection to your NAS.

Best regards,
Kapitein Haak.

To install an SSL certificate on your ASUSTor NAS, including any intermediate certificates:

Combine your SSL certificate and the intermediate certificates into one file in the correct order.
Ensure all certificates and your private key are in PEM format.
Import this combined certificate file and your private key into your ASUSTOR NAS via the Certificate Manager in the ADM interface.
No special steps are required for the intermediate certificates if they are correctly combined with your SSL certificate.
Make sure your NAS firmware is up to date to avoid any known issues with SSL certificate handling.
