Really fundamental question here, but nothing a quick google search is lending itself to. Do I need to generate a separate private key for each cert I use in apache?
Server details:

In this context, every certificate is a Public Key paired with a matching Private Key.
The Public and Private key portions of the certificate work together.
So yes, every cert has a separate private key.
