Microsoft CERTSRV

Why does this have to be so difficult?

I want to create a cert on the palo.

Device > Certificate Management > Certificates > Generate

Highlight Generated Certificate > Export Certificate > Open with Notepad

Copy contents

Go to my Microsoft CERTSRV > Request a Certificate

Here is where it starts to get a little fuzzy.....

User Certificate or Advanced Certificate request?

I chose Advanced

Pasted contents

Template I chose webserver

Download .csr

Back to Palo

Import

File format is .PEM

I know someone is going to say to use OpenSSL to convert it, but I can't figure that bit out and can't install it on my work PC. Is there any other way? Why wouldn't the Palo's accept .csr, I would think that a lot of businesses have a Microsoft certsrv?

@MrWonderful,

So obviously the real answer is using OpenSSL : - )
Once you actually generate the certificate it should be in .cer format, which the firewall is able to import without issue. If your CSR has been processed, you shouldn't be outputing a CSR file in response.

Got OpenSSL installed and got it converted, but now I need a key. Any ideas?

@MrWonderful,

What's asking for the key? If imported properly the firewall has the key from the initial request.
