FindVUK tool - get VUK of all Blurays supported by DVDfab applications

[Roof Tile]

Hello Nalor! I was finally getting back into getting some blu rays through the VUK process when one of them decided to be a bit strange. I was using VUK on the blu rays for the TNG series boxset and all of them went through it just fine, all except Season 2 Disc 1. For some reason VUK seems to be having trouble figuring out what to do with that one. The disc seems perfectly fine and even plays in VLC like normal (which doesn't surprise me given the series popularity made them all being scanned already likely). It's just strange that it's having trouble with it compared to the others. In any case, I've taken the log file and uploaded it to this post for your perusal to find what may be causing the problem. As always I thank you extremely for your work and hope you stay happy and healthy!

Hello! I just noticed in the keydb.cfg some newer releases include both unitkeys and VUKs. If VUKs are no longer available from the DVDFab memory dump, how are people obtaining them? Also, when it comes to decrypting, what is the difference between using a VUK and unitkeys? Thanks!

Please upload the log somewhere else as it's still not approved here. Thanks!

It does not make a difference if using VUK or directly UnitKeys. Internally the VUK is used to calculate the UnitKeys - so in the end it's always UnitKeys which are used to decrypt something.

And about the source of this VUKs: I guess the users have host certificates not published yet.

Is it actually the case that VUKs are no longer available via DVDFab?

As long as these people who do have unpublished (especially also AACS2.0) HCs share their VUKs / UKs (or kinda "share" them like with DVDFab), I think it's actually for the benefit of the community (of people which want to be able to play back the stuff they bought on open source platforms or even once after BluRay players are no longer produced), that these HCs are not made public - makes it more difficult to revoke them ;-)

Does someone have a SHA256 or similar hash for the installer of 9.2.1.2 (IIRC that was the last version that worked)? DVDFab doesn't offer older versions to download, it seems.

Thanks :-)

Passkey 9.2.1.2 (2017.07.24)

SHA-256: 15C9B88592B8751C8D9B19A508D318A02824E5745FF2B1978C8F70FFE6A7990E

[coricopat]

thx :-) ... and again, matches the download from videohelp.com. (So should be safe, unless of course you're the admin there ;-P)

Yes, DVDfab doesn't use VUKs anymore and it has never used them for UHD discs.

However, if you want VUKs for non-UHD discs, why not try "FindVUK - AACSkeys.bat" instead of old DVDfab version?

You may have to copy-paste Device Keys and Host Certificate from this post into your KEYDB manually though.

Well in principle the VID is enough, so I don't mind.

But just for "completeness"... is there "open" any way to get the VUKs vor UHDs?
IIRC, one could not extract them from MakeMKV's disatt.dat either.

Sure, that's anyway clear :-)

YW. Yeah. Definitely not.

Passkey 9.4.5.2 is the last version that worked, everything later does not include unitkeys any longer in a way where I know how to parse them.

Ah, didn't see that the file wasn't approved yet, strange. Well, here's a MEGA link to the tiny thing for your perusal.

Thanks! Checked the log and something is failing during analysis of the memory dump.
Can you please also upload the memory dump?
(the file >F:\Vxxxxxff\Blxxxxxuff\FindVUK Tool\FindVUK Program\dump\85670F37043778F22A8243E816DACC20946941DB_STAR_TREK_TNG_S2_D1.dmp<)

Thanks!

[Roof Tile]

No problem, here is a MEGA for that. Hope it has something useful for you!

Thanks! This helped! It's really funny that this problem never appeared before ...

Please try this version here: FindVUK 1.77

In case it's working I'll publish it as new official version

[Roof Tile]

Yup, seemed to work normally and uploaded all the stuff as usual! Thanks for the fix!

[nalor]

Published FindVUK 1.77 "officially".

No new features, just 2 bugfixes.

[coricopat]

Is someone else seeing issues with FindVUK + DVDFab since version 13.0.2.5?

[coricopat]

It works again after downgrading to 13.0.0.4 (which is the last version from which I have a standalone installer - I guess the versions in between were not available as standalone installer, or does any one have them?)

Send the logs with the error message via PM @nalor.
