Can't install new certificate

[Belthazor]

I am having problems installing new certificate to our OPNSense machine. The certificate is generated by Sectigo. I cannot add their CA certificate (in System -> Trust -> Authorities), all I get is a pointless error that I should check the logs. The logs say something like this:

Code: [Select]

[OPNsense\Trust\Cert:cert.a09c548b-ba6b-4a28-a32f-65a4d96c5183.caref] Please select a valid certificate from the list{66ad4fb310ccb}
Before you ask, yes it is PEM format certificate and it is Sectigo CA certificate file...

Thanks guys.

Which root would that be exactly ?

Look for it using the serial number on https://crt.sh

Assuming that Sectigo uses the same chain of trust for their own website, try this:

System:Trust:Authorities, click +

Descriptive name: Sectigo
Method: Import an existing Certificate Authority
Certificate data: paste in text below

Thanks guys for trying to help me out.

Eventually I managed to install after first deleting all the certificates from Trust->Certificates. Then I added the Sectigo Certificate and temporarily created a webui certificate for the router.

After that I wanted to add our new certificate to Trust->Certificates. I added the private key and certificate (it's wildcard certificate) and the system just recognized it as self-signed certificate. I wanted to manually switch issuer to Sectigo, however I am getting a new error

Code: [Select]

missing CA key

[doktornotor]

I cannot add their CA certificate (in System -> Trust -> Authorities), all I get is a pointless error that I should check the logs.

Maybe you could just post the CA certificate you are trying to add here?

Obviously you cannot do any such thing with certificates issued by CAs not managed by you/OPNsnse (i.e. those for which you do not have a private key.)

[Belthazor]

Okay, then I am obviously missing something. I need to add the SSL certificate to our router. I remember it went smothly last time, but now we renewed it and I need to switch them. So how do I install the new certificate? If I just dump the key and the certificate and try to use it as UI certificate I am getting an error that the certificate is self-signed and I can't get into the GUI.

[doktornotor]

Dump what? The Sectigo CA private key?   

[Belthazor]

No, private key of the certificate for our own domain.

[doktornotor]

Yeah, let's try again:

I had exactly the same issue with a digicert certificate. When I imported it it showed up as self signed, although the Digicert issuein CA is my Authorities store.
After some try and error this is how I solved it:

• Import the certificate it will show up as self signed.
• Edit the certificate make sure the action is is set to "Reissue and Replace certificate and make sure you select the correct CA
• Click Save --> You will get an error
• Change the Action to "Create a certificate Signing Request" and Save. You should now see the certificate with the correct CA
• Click on edit and select "Import Certificate (Signed by CA) it should be the only option
• Save it.

After this you should see the certificate with the correct CA assigned.

Thank you!  This tip did it for me this evening, as well.   

[j.koopmann]

When I edit the certificate all the options other than "manual" are greyed out... Any idea?
