So why should playing Blu-ray discs be any different?
DVDs have one set of hard-coded keys which were cracked and published a long time ago - to revoke or change them would have required replacing or manually 'updating' every DVD player (not a viable option.) The IP holders learnt this lesson well and so Blu-ray has mechanisms for revoking/updating keys and certificates. Just because the DRM algorythm is public domain, doesn't mean the keys are generally available.
I don't have a blu-ray player and don't have any blue-ray discs either. That is I don't know how it is working. But there is something I don't understand. If I buy a standalone table-top blue-ray player, how will it get the keys to play the purchased blu-ray discs?
There is a default set of keys in the player when you buy it. After that, each disc you play can have key updates included, and these will update the ones in your player. It's a complicated system, but that's basically how it goes.
Thanks, I see now. In this case it is hard to believe that those default keys has not been "extracted" and are not available so that computer programs could use them. I am not interested but I guess one could download them from some site and copy them to the right place where the blu-ray player software can find them. Or is this not feasible?
