use most the PKI/SSL tool on the box to generate a certificate signing 
request (CSR), copy this small test file any way you want (copy/paste 
from a terminal session?  put on a USB stick?) and send it to a 
certificate authority, they generate a signed certificate, you bring the 
resulting CRT back and import it back into the server's key store.

if this is https just for private use, you could run your own private 
root CA, sign your own certificates, it would simply be necessary to 
import your CA's public key into any browser that you want to trust the 
signed private keys.
