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

[MrPenguin]

Hi,

Can I assume that any entry whose comment contains "/BEE" declares that disk has "Bus Encryption Enabled", please? Because if so, then I believe these two entries would need updating accordingly:

0xD3F08E3F0C831B4858172FDC606F3520068EFF56 = OPPENHEIMER (Oppenheimer)
0x317A0AAFB05CBE1E1FB3BDF96D3B2F95C9053C20 = OPPENHEIMER_SPECIAL_FEATURES (Special Features)

I've already tried to update them myself, except my "synchronize" didn't change anything .

Thanks.

here is a new "test" release - I've added libredrive support for supported UHD drives:
when it comes to validation, "libredrive mode" is enabled -> this disables the bus-encryption and so it's easily possible for FindVUK to validate the current values.
I tried it with 1 disc and it worked (because I only own 1 UHD).

Download from here: FindVUK_1.70

Please report if it's working - thanks

@mick0 - it should also fix the wrong calculation of the driveid, but I did not add your 2nd idea yet as I read our message a minute ago.

Just tested a German and US UHD and it seem to work as you describe ! Nice.
Oh, I always wanted to ask - why does the size of the local keydb decreases in size when FindVUK loads it ? Or is it only my system where this happens ...

[SamuriHL]

I just tested it out with my bu40n drive and it worked perfectly. Very nice!

Thanks for the update. I tried and it works, but I'm interested in a deeper explanation of what changed. For me, the "get ReadDataKey from dump and use that to bypass bus encryption" method from before already worked (?), has fewer apparent dependencies and is several seconds faster for validating the unit keys than this new approach of using LibreDrive. In other words, 1.70 is slower than 1.67, the last version I tested. I'm probably not the intended audience, but who is? Is it people like metalsonic88 and mick0 with drives that expect AACS2 authentication but still work with DVDFab because they have friendly firmware?

[SamuriHL]

They're not "friendly" drives, they're official drives. Official drives require aacs 2.x bus encryption and there are no host certs available for that. So while dvdfab is able to use certain official drives like my bu40n, with that bus encryption there was no way to validate the extracted key. With libredrive active, bus encryption is simply disabled so that validation can take place.

This is not entirely accurate.

FindVUK starting from v1.68 extracts data key from DVDFab on UHD official drives such as BU40N or WH16NS60. No LibreDrive or Host Certificate is required for playback/decrypt/verify when data keys are available.

[mick0]

It seems FindVUK 1.70 now fails during validation step on my system. FindVUK 1.68 works.

I don't currently have makemkv installed on this system, but FindVUK thinks it is and tries to use it.

Can you perhaps add an config option for disabling LD support?

Nor is this entirely accurate. That may work on blu-ray but trust me, it didn't work for me on UHD's. It does now with 1.70 and LibreDrive.

Well, it works on my WH16NS60 with slightly patched libaacs (UHD and BD). Using data keys is the official way to handle bus encryption after all and it is what DVDfab and PowerDVD are using for instance. It should definitely work, unless FindVUK is unable to extract the data key for your disc/drive for some reason.

[SamuriHL]

1.70 seems to be able to but 1.68 wasn't. No idea why but everything is working great now. If only dvdfab would add pioneer drive support we'd be in the golden age.

With a physical disc it's actually taking an entire minute for FindVUK to enable LD in 1.70, even though FindVUK already got the RDK a few steps earlier.

Is it waiting for the disc to completely finish loading in MakeMKV before moving on? Previously, getting past the bus encryption would take less than a second by directly using the key that it already found.

I have tested my full supply of UHD discs and several regular Blu-rays and everything appears to be in working order. I'll probably try and retest my full library along with anything new I get over the holidays to see if there are any other issues hiding away somewhere, but for right now I have no complaints. With the help of mick0 I have even been able to play all my UHDs directly from the drive. So thank you nalor and thank you mick0, you both are legends.

Additionally, I have noticed no change in the speed at which discs are handled by FindVUK. Whether UHD or Blu-ray it only takes a few seconds, less than 30 even in the longest cases, for the whole process to complete once it recognizes the disc.

[nalor]

Just released 1.71 "officially" through the auto updater, the previous 1.70 introduced a bug because it calculated the driveid for AACS1 discs wrong and therefore the RDK got stored in the wrong directory.

Next I checked DVDfab 13 and added support for it - only small changes where necessary

And regarding libredrive support: it's only used in case the drive has an AACS2 certificate - so for use with a uhd-friendly drive nothing should change.

And for drives that are "official" AACS2 UHD drives I thought that the RDK method is not working at all.

@magician - can you tell me your drive model and maybe send me a log from FindVUK 1.68 when using the RDK with an UHD in the drive for validation? Thanks

RDK method works just fine on AACS2 drives as long as the RDK is available.

Next update 1.72:
* Libredrive support is now disabled by default, can be enabled using an INI switch if desired (I tested it with my BU40N 1.00 drive and it's really working with only the RDK ... )
* DVDfab 13 logfile is assumed to be always enabled (there's a flag in the dvdfab config file that was either 0 or 1 in the past - but now it reports something like "34589778" or also "0" sometimes ... but the log is nevertheless written.

This is what I've been trying to tell you guys all along.
