So how do you take back your online communication from the prying eyes of the government? Enter Trsst, a new social network that promises to be a white knight of media, keeping all of your cat posts and private messages safe and secure forever. Trsst itself can’t crack into your content, they claim, because you keep your own encryption keys. That also means they can’t hand your stuff over to the government, even under court order.
