How do I add a trusted root certificate?

I am hosting my private Certificate authority to encrypt most of my internal traffic, why is it so [expletive removed] complicated to add a root certificate to a tizen TV?
Please, I have used the email CEO and various other SAMSUNG options, now they tell me that the expert developers are around on these forums. So from what I gather I either get root access to the device, which is not an open secret or someone can point me to documentation on how to just add a simple file to the /ssl directory?
