If MakeMKV is allowed to enable LibreDrive a power off is need to reset your drive and allow VLC to play bus encrypted discs There is NO POINT in sharing these keys as they will not work for anyone else RDK unlike the other keys are disc+drive specific. Put both VID and MK in keydb.cfg to get the VUK in the. it seems libaacs has some bugs in aacs keys calculation flow. Besides libaacs also aacskeys supports input of VID instead of using a HC

Device Keys for MK retrieval are public for up to MKBv71. VID in combination with MK can be used to calculate VUK/UK. VID can also be put in the KEYDB.cfg file instead of the local cache Warning: in case the firmware of a drive is updated, the RDK for all discs possible changes The RDK for the disc is unique for every drive so repeat the steps for all your drives that support bus encryption As of this moment, this is v1.15.1 or later The following steps are performed on Windows but they are similar for Linux & MacĬhoose a version that has an unrevoked HC. Update: Following programs automate the steps below Please support MakeMKV for the work that they do.

This is based purely on public information released by MakeMKV but it is nonobvious. This guide shows you how to get these keys from MakeMKV. Just like FindVUK can get VUK/UK from DVDFab, it's possible to get VID/RDK from other players or rippers that contain an unrevoked HC. However, to have this RDK in the libaacs cache, the disc had to be played before the certificate was revoked. libaacs 0.11.0 supports cached RDK keys allowing playback of bus encrypted discs without a valid HC. The RDK affects a minority of BD discs but 100% of UHD discs. However RDK is unique for every drive and cannot be shared in the same way. VLC), this causes problems for new and old (!) discs as the HC is needed to retrieve the VID (aacs decryption) and the RDK (bus encryption) unless keys are cached or available in KEYDB.cfg.Įven though VID is always needed in theory to retrieve VUK/UK, in practice this is not a problem because these keys can be found using FindVUK or by downloading FindVUK's KEYDB.cfg containing a large database of keys. When relying on libaacs for playback (e.g. As the amount of discs with a newer MKB version increases, more and more people will find themselves in the situation where their drives have permanently revoked this HC. The last known public Host Certificate (HC) needed for Blu-ray playback has been revoked in MKBv72.
