Auth key & certificate for push notifications

Hello,
So, here is the situation I currently have "APNS Auth key (*.p8) "and I have "APNS certificate".
Only APNS Auth key is used on backend.
Is it safe to just delete certificate (it's not used on backend)? Will it break the ability to send push notifications?
That certificate is going to expire soon, so I need to figure out how to keep APNS working after cert expires.

Yes. The certificate is only used to authenticate senders to the APNs server, and does not represent any system-wide configuration to send push notifications.

No.

Hi there

What's the difference between .pem et .p8 on the server ?

I use PHP on my server by my host.
