how does one get missing keys for KEYDB.CFG?

[jemima]

Hey there.

I have a BluRay, which MakeMKV can already read, but plain libaacs + the well-known KEYDB.CFG can't.
It's the 4th disc (i.e. bonuses) from Avatar 2 3D (all other 3 discs of that package have their keys already in KEYDB.CFG).

Can one somehow get the key from MakeMKV or how are keys usually added to KEYDB.CFG?

Thanks,
jemima

How up to date is your keydb.cfg? Looking at the files from http://fvonline-db.bplaced.net/ it seems, there are several entries for Avatar 2 3D. Even four different ones for "AVATAR_THE_WAY_OF_WATER_BONUS".

If they don't help, you probably would need the help of the https://forum.doom9.org/showthread.php?t=172472 FindVUK program, which though works with DVDfab, not MakeMKV to extract keys.

The honking sound in the base of my brain is telling me you might also be a Linux user, in which case FindVUK will only be of limited use to you.

Hey there,

I am looking for a similar solution as a Linux user. Any chance to add the VUK to an entry of KEYDB.cfg, which is already there but only contains U: CPS Unit Key ( https://github.com/rraptorr/libaacs/blo ... /KEYDB.cfg )? I came across https://forum.doom9.org/showthread.php? ... ost1979303 but it does not work for me (maybe outdated?) on Debian 12.

The UHD disc is however playable through VLC after following the instructions of archlinux ( https://wiki.archlinux.org/title/Blu-ray ) but I'd very much like to make an MKV.

Thank you!

Hey there,

Any advice for another Linux user?

Thanks!

Which particular disk are you talking about? Can you post its DiscID from KEYDB please?

The get-rdk.sh script on Doom9 is intended for non-UHD disks. You cannot use it to discover a UHD disk's RDK because there are no publicly known host certificates for AACSv2.
