Finding VUKs on Linux

ca9mbu · 18th April 2021, 12:17

Hi,

I've played a few Bluray discs successfully already using MPlayer + libaacs and KEYDB.cfg. I've just purchased another one that doesn't have a VUK in KEYDB.cfg. As I'd like to contribute back to that database I'm now looking at options for being able to get the VUK myself using Linux tools alone.

1. DumpHD looks promising from browsing this forum; is DumpHD-0.61 the latest version, and if so is there anything like an 'official' download site for it? I don't much fancy "google for it and hope that a random site that offers it hasn't altered its contents"
2. aacs_info shows my device is at MKBv71 but complains that no suitable processing keys are present:

Code:

$ aacs_info /media/bluray
Opening /media/bluray using libaacs 0.11.0 ...
aacs.c:597: Error calculating media key. Missing right processing key ?
mmc.c:674: Drive does not support reading drive certificate
aacs.c:1142: Unable to read drive certificate
libaacs open failed: No matching processing key
aacs.c:597: Error calculating media key. Missing right processing key ?
aacs.c:1484: aacs_get_mk() failed
Disc ID: 41D719343D13D88D3B94486E2BC751E92A3621BD
VID    : ED359AEB00FDD6A79A573B6ABB4B0BB9
MK     : ???
MKBv   : 71
PMSN   : ???

Although I can find host keys for MKBv 71 in this forum, the processing keys only seem to go up as far as MKBv 68. Presumably, just like libaacs, DumpHD will need those keys in order to calculate the MK?

Subscribing to this post because as a linux user who extracted all keys in a Win10 VM, I'm looking forward to do the same with native tools as well.

I would heartily recommend this post, as well as investing in a standard BluRay disk that uses MKBv81.
