If this goes to overtime , Aretha has to sing for 8 minutes . <| sep |> I still think the show would ' ve been way more interesting if Shane killed Rick and lead the group . May they wouldn ' t be as pure but they ' d be a hell of a lot more compelling . By the way , I love the raw intensity in this scene . <| sep |> As I said , in a welldesigned highly secure signing situation , there is not a single person anywhere in the world who does or ever did have access to the actual signing keys . There ' s literally no key to give , only a piece of extremely expensive hardware who ' s sole purpose is to resist attempts to recover key information likely with plenty of selfdestruct conditions . In highly secure situations , these signing modules don ' t even store the key , just enough information to recover the key when several other pieces of secret information are correctly provided . We ' re not talking about your standard personal computer sitting somewhere in a computer lab with a RSA private key on its hard drive . Further , in a well designed secure private key management facility , a significant number of people will have to be compelled to assist , and if any one of those people decides not to cooperate , you will be screwed . I ' m not saying it ' s not possible , obviously there ' s no such that as completely unbreakable security , but getting a malicious update signed using signing keys that are stored in a welldesigned highly secure facility is much harder than most people realise .
