Can anyone please tell, what do I have to do with the key file ?
I Mean, do I have to add it to Registry in order to download the video file ?
and If so, Can anyone please Explain to me how to get that key file, and how to encrypt it like that ?

I know my questions might be silly for experts, but please forgive me as I'm still beginner and this is my first time to download a Live Video Streaming..
