Store New Recaptcha keys in config file

  
Hi,

I am using the New Recaptcha widget from forge.
I need to store the keys (site key and secret key) in some confige file,
and load them in the prepartion of specific web screen.

How can I do that?
I would use Site properties (under the Data tab) for that, so it can be set through Service Center by admins.
