AACS v82 Blu-ray Disc dump Submission

#1 Post by raknam » Fri Jun 06, 2025 6:30 pm

Hello,

Here are 3 Bluray I can't decrypt
MakeMKV v1.18.1
KeyDB.cfg updated a few minutes ago

Is there a howto doc to find the key ourself?

They're already in the keydb from what I can see. Make sure you extract the keydb.cfg file to your MakeMKV data directory. Additionally if you're on Windows, this post might help. Read it thoroughly.

Yes, I have used FindVUK just after posting here.
But MakeMKV is still not able to uncrypt them.
I tried on my both Bluray readers (one is on LibreDrive Firmware).

Update, Status has changed since yesterday for my discs \o/

Have you tried downloading the latest KEYDB.cfg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?

Yes, I used the KeyDB Helper utility who done this directly for me.
I was able to dump my discs. :)

Thanks for helping me
