certificates for web apps. (Documentation)

I found a wonderful article on the creating and installation of server certificates for Xojo web apps.

SSL for Standalone Web Apps

I have two questions about this document.

# Remove the passphrase from the key (so you don’t have to type it in to restart Apache)
I’m not sure this is well explained. I do not know what passphrase they are referring to.

Somewhat less confusing but still odd.
Now that you have a correctly named and formatted certificate file, you’ll need to make sure it is next to the built web app when it runs.

The command line options for the application allow you to specify a path to the certificate but the notes also recommends you put it with the application.
