bluray encryption was never "cracked". even the above link is clear that it wasn't a crack. just that the encryption mechanism was well understood, but it requires a device key to generate the volume unique key (VUK) that is necessary to decode each individual disc. VUKs can't be revoked, but they are unique to each disc (pressing). device keys can, and when they are, they can't be used to generate a VUK any longer.

so one has 2 options, a database of VUKs that others generate (don't need a device key then) or getting a device to give up its key so that one can generate VUKs onesself. The problem with this is, that that key (if made public) will then be revoked itself.

i.e. I don't consider this being cracked, this is the encryption working exactly as designed.
