Help with externaly genrated certificate

Hey all,

I have generated a self signed certificate and key on another device, and would like to use it for my HA.
I have exported the certificate and key. I had to put a password when exporting the key.
I have copied the cert and key to the /SSL/ folder.

In all of the guides I read, I am missing one important step - Where do I put the password I used when I exported the key?
