BD-Video Key Extraction
From Redump Wiki
This guide is only for Dumping Keys from Blu-Ray Video discs, for dumping the discs see Disc Dumping Guide (MPF).
This guide works on Media Key Block (MKB) version 68 and below. For reference MKBv69 was skipped, and MKBv70 was released around 2019-07.
Software
Some versions of Find VUK and DVDFab don't play well together. Your experience may vary.
- Find VUK (unzip FindVUK in a folder with write-access)
- VLC Player (install)
Check MKB version before Dumping
- If you ever put a disc with MKBv72 or higher, the key dump method below will never work again in that drive until new processing keys are available. I don't know the technical details but it seems Blu-Ray discs are able to update keys in your drives flash memory. After putting any MKBv72 disc that drive will only be able to decrypt using proprietary software.
- As I understand, you are allowed to put the disc into the drive, only if you playback/decrypt the disc it will update your drive keys. So checking MKB version before playback should be possible.
Dumping Guide
- Start Here
- Then create the directory "temp" at C:\ and follow the steps on the same tutorial in Step #1 thread under "Debugging:".
- Now playback any BDMV with VLC and the key will outputted to the file "c:\temp\debuglog_aacs.txt"
