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.

Check PM...

Thanks guys.

I'll have a look

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 ost1979303 but it does not work for me (maybe outdated?)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!

Any advice for another Linux user?

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.

another linux user here looking for the same help.

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

I'm talking about Disc 1 of The Boondocks The Complete First Season set.

I don't know how to find the DiscID in KEYDB since the disc isn't in there.

[MrPenguin]

I don't know how to find the DiscID in KEYDB since the disc isn't in there.

That's the SHA1 hash of the disk's AACS/Unit_Key_RO.inf file:

Code: Select all

$ sha1sum AACS/Unit_Key_RO.inf

If you have the physical disk then you should be able to execute FindVUK.exe inside wineconsole to upload the disk's entry into KEYDB:

Code: Select all

> findvuk validateDisc drive=<whatever-your-UHD-drive-letter-is>

Your KEYDB.cfg entry would still need to contain an entry for your disk to validate, of course.

Thanks for your reply!

I was able to run `FindVUK.exe` with the following:

Code: Select all

wine FindVUK.exe /validateDisc /drive=g

I found the appropriate drive by examining the output of:

Code: Select all

ls -la ${WINEPREFIX}/dosdrives

however this command still ends up hanging:

Code: Select all

AACS folder on disc in drive >g< is not accessible - keep waiting for disc to appear (abort with ESC)

from https://forum.doom9.org/showthread.php?t=172472 it looks like I need to buy a license to something called dvdfab?

Is there a way to use this using just makemkv?

FindVUK uses one of the DVDFab products to find the VUK or unit/title keys.

[ezzieyguywuf]

ok, thanks for your reply.

Just to be clear, from what I can see dvdfab costs $200+, so my only option is to either pay this fee or use makemkv, I have no other recourse for accessing my bluray?

Does makemkv contribute vuks to the FindVUKS datasabase or nah?

No, MakeMKV does not.

FindVUK uses any one of:

DVDFab
DVDFab Passkey
DVDFab MediaPlayer

I wouldn't buy it either. Way, way overpriced software that isn't that good anyway.

If you have suitable device keys and a host certificate you can derive the keys for 1080p discs using FindVUK in aacskeys mode. This uses the opensource aacskeys utility to calculate keys independently of any 3rd party commercial software.

Suitable device keys are publicly available on the Doom9 forum and they work with even the latest AACS1.0 discs (including MKBv82).

I don't believe there is a publicly available, unrevoked AACS1.0 host certificate at this stage, but you can work around this by extracting the volume ID (VID) of your discs with MakeMKV. Once you have the VID you can pass it to aacskeys and it will calculate all of the keys for your disc. I believe there are instructions which cover this use case on the Doom9 forum.

If you have any AACS2.0 discs and an Asus/LG drive you can always post the disc dumps to this forum and the keys will be added to the public keydb. This option is not currently available for Pioneer drives.

Is this the relevant part of the makemkv output to get the volume id?

Code: Select all

Using LibreDrive mode (v01.0 id=22C9CC746265)

Or is there something else I should be looking for?

For the device keys, what search terms would I use to find the appropriate ones, and how do I use this device key?

Thanks for the help this gives me hope!
