How to remove certificates

How to remove certificates

Hello,

I have been trying for the last few days to get openssl working with untangle firewall openssl vpn server.

Initially i uploaded some certs but i believe i had to upload all three certs: client, key and ca cert.  So i was looking to upload a pk12 cert but i am now getting an error saying cert already exist.

How do i delete the certs i have already uploaded and also is there a document on how we should setup openssl vpn?

We are looking to deploy this to 500+ devices and now trying to get this working before moving to next stage.

Thanks
