Running gateway service without SSL for testing

[Mohammad Islam]

Hi,Currently Knox gateway service is defaulted to "https" protocol. Is there a 
way to turn it off and make it "http" for dev purpose?
I'm getting the error "certificate signed by unknown authority" for some of the 
https accesses. 
Alternatively, is there a quick way of getting self-signed certificate for dev 
and testing purpose?
Regards,Mohammad
