How do I install a custom root CA

Post by jfgratton »

Hi,
I have my own rootCA.key + rootCA.crt files which are my own root certificate autorities, and my own nascert.crt & nascert.key

I know how to install my own nascert.key +.crt file in ADM's Certificate Manager. I even install rootCA.crt as the Intermediate Cert.

Still, when I https://nas:8001, it still shows as unsecure, letting me believe that my rootCA is not recognized as such by my NAS.

I tried installing rootCA.key + rootCA.crt but it declines, saying "Invalid certificate (ref. 5041)" <== wth is ref 5041 ? :)

The thing is, all my linux boxes use rootCA.crt as a trusted CA, so where should I put it in my NAS box ? Do I need to SSH on the NAS and copy it at some place (root@nas already has my key in .ssh/authorized_keys, so no need for a complete walkthrought here).

Thanks

Hi,

I faced same situation and got same error code few days ago.
After many tries, I found the problem is that I encrypted my private key with AES256.
You may try to don't put this argument "-aesXXX" when generating private key.

ASUSSTOR ADM seems didn't implement this function...
