Wow. Overly convoluted description of a SSL cert. In fact I would say if you listen to the whole video you will be tricked into thinking an SSL cert can save you from phishing attacks. Which it can and can't depending on how good the attacker is.
Either way, this is common practice on the internet. Not really big news. Nobody freaked out when Amazon created a bunch of SSL certs that now come pre installed on most devices. Just sayin'
