Going to add some information here that maybe will help people and can be linked to. People have been asking about the keydb.cfg file lately and how to know if a disc they have has a key in it. If you have PowerShell on your machine, do the following from a powershell command prompt:
Code: Select all
Get-FileHash X:\aacs\unit_key_ro.inf -Algorithm SHA1
Where X is the drive letter for your disc. You'll get a hash printed out. Copy that hash and then open the keydb.cfg file. Search for that hash to see if an entry for your disc exists. If so, it MIGHT decrypt with MakeMKV if you set up the keydb.cfg file correctly. I say might because it appears that MakeMKV only uses the VUK value from a keydb entry and not the unit key(s). If the entry only has the unit key(s) then you may have to either wait for MakeMKV to add support or use another decryptor to realtime decrypt the disc so that MakeMKV can open it.
There's also been questions about how to use the keydb.cfg with MakeMKV. So try this:
Open MakeMKV, go to preferences
Go to the General tab, and look at the MakeMKV data-directory field. If it's empty, manually set it to your .MakeMKV directory (on windows it's usually: c:/users/username/.MakeMKV where username is the currently logged in user). Also note this path.
Download the latest keydb.cfg (or use FindVUK to syncrhonize it to your aacs directory from which you can copy it to) and copy the KEYDB.cfg file to your MakeMKV data-directory path. NOTE: That on some systems the case will matter, so it should always be KEYDB.cfg to ensure it gets read properly.
Now restart MakeMKV and you should be good to go. Obviously the keydb.cfg file needs to be updated periodically. In this way, FindVUK is helpful as it can synchronize the keydb regularly. You just need to modify it to copy the keydb.cfg file to your MakeMKV data-directory or manually copy it after the sync. Coopervid posted instructions on how to automate that copy here:

As for what that hash is above, it's the calculated disc ID for your disc. That's how the keydb.cfg identifies your variation of a particular title.
