How to handle expired OpenVPN Client/Server Certificates
I am just wondering what I should be doing with expired certificates? I have been creating Server/Client certificates with a 1 year expiry, and when they expire I have just been generating new certificates. So far I haven't deleted any certificates form the Certificate Manager.
Is there a practical way to extend the expiry date for another year, or is it better to just create new certificates?
Is that the right thing to do? Do I need to revoke the expired certificates, or should I just be deleting them? AFAIK then certificates have not been compromised in any way. (Unless my phone has been hacked and they have been exfiltrated, but I have seen no hint of that.)
At the moment all you can do is make new ones. Since the old ones have expired and are invalid, you can safely delete them.
