This guide is only for Dumping Keys from Blu-Ray Video discs, for dumping the discs see Disc Dumping Guide (MPF).
Multiple methods for dumping BD-Video below, each with their own benefits and drawbacks.
Contents |
Desired Information
With this guide, we'll be looking to find / dump the following information for your BD-Video disc:
- AACS MKB version number
- Media Key
- Volume ID
- Volume Unique Key
- Unit Key File Hash (DiscID)
A proper redump entry will display this info as under Protection in this example.
Method 1: FindVUK (AACSkeys mode)
This method is the easiest, and works on Media Key Block (MKB) versions past 68, but past version 68 (v69 skipped, v70 in 2019-07) it can only extract the UnitKey (UK). It works as long as the drive has not yet revoked the host certificate (it's only valid until mkbv71 and got revoked in 72).
- Download and unzip the latest version of FindVUK
- Double click "FindVUK - Synchronize.bat"
- Now you will dump the keys. You do one of either two methods:
- Drag and drop the drive icon where the disc is inserted to the file "FindVUK - AACSkeys.bat" (NOTE: This requires no spaces being anywhere in the file path where your FindVUK folder is).
- OR open up the command line and "cd" (change directory) to the location to inside your FindVUK folder, then run this command: FindVUK.exe AACSkeys=X (where "X" is the drive letter).
- In your FindVUK folder, go into the OnlineDB_Backup subfolder. You will find an xml file with your key info to submit to redump!
Method 2: FindVUK + DVD Fab
Method 2 is believed to have similar dumping compatibility to Method 1. The only thing unknown / untested is that whether Method 1 can also extract UnitKey (UK) v70 (circa 2019-07), which Method 2 can. If Method 1 can also do this, then Method 2 should be considered deprecated as it's a more convoluted / difficult process.
Software
Some versions of FindVUK and DVDFab don't play well together. Your experience may vary.
Dumping
- DVDFab should be closed.
- Insert Blu-Ray disc.
- Launch FindVUK.exe, this will automatically launch DVDFab.
- Select "Try" to use DVDFab as a trial.
- A progress bar window should appear as DVDFab is processing the disc, which takes a few seconds. FindVUK should report that it found the key.
- Eject the disc, close FindVUK, close DVDFab (you may have to forcibly kill the process, for me it frequently hangs at that time).
- In your FindVUK folder, go into the OnlineDB_Backup subfolder. You will find an xml file with your key info to submit to redump!
Submitting .XML / Key info
Now we'll discuss how to submit the XML file info from FindVUK's OnlineDB_Backup subfolder.
Let's have a look at this XML output:
<?xml version="1.0" encoding="UTF-8"?> <Bluray> <FileType>BlurayMetaXML</FileType> <DiscId Date="2008-04-30">D6630E5AA891CE4164A44E627E5672F092D0D717</DiscId> <VolumeId>FC3AAC79EA225AE1448C983C98259319</VolumeId> <MediaKey>D3A5957A0219001AB62D31EAC9A10E5A</MediaKey> <VolumeUniqueKey>F283D691673583569819F114460A6BF7</VolumeUniqueKey> <VolumeLabel>BDROM</VolumeLabel> <BDplus>0</BDplus> <BusEncryptionEnabled>0</BusEncryptionEnabled> <MKBrev>7</MKBrev> <MainPlaylist/> <UnitKeys> <UnitKey Nr="1">562D5AC9EF5925866D7F07BBDC8ADFEF</UnitKey> </UnitKeys> <MetaTitles> <MetaTitle Language="" Manual="1">Metal Gear Solid 4 Bonus Disc</MetaTitle> </MetaTitles> <Hashes> <Hash Type="MD5" File="MKB_RO.inf" Size="1048576">BF8D213F679D3423526B1185B30C63D2</Hash> </Hashes> <Application>FindVUK 1.09</Application> <VolumeSize>24395972608</VolumeSize> </Bluray>
This information should be submitted to the Redump entry's "Comments" section as follows:
BD-Video Protection: AACS (MKB version 7) Media Key: D3A5957A0219001AB62D31EAC9A10E5A Volume ID: FC3AAC79EA225AE1448C983C98259319 Volume Unique Key: F283D691673583569819F114460A6BF7 Unit Key File Hash: D6630E5AA891CE4164A44E627E5672F092D0D717
