The KeyDB.cfg file is the unsung hero of the ripping world. It represents the collective effort of the internet to preserve access to physical media.
: The file should generally be named keydb.cfg . On some systems (like Linux), it may need to be exactly KEYDB.cfg (all uppercase) to be recognized.
Currently, MakeMKV handles AACS2 decryption largely through its own internal mechanisms and online lookups. The reliance on a static local text file like KeyDB.cfg is slowly diminishing in favor of dynamic, online database queries performed by the software itself. keydb.cfg makemkv
: If a movie was released yesterday, its specific "hash" might not be in the database yet. The community-driven nature of these files means there is a slight delay for new titles.
While MakeMKV is free to use for DVDs and AVCHD (and has a generous beta key system for Blu-ray), the actual decryption capabilities vary. The KeyDB
: For keydb.cfg to work with MakeMKV, the entry for a specific disc must contain a valid VUK . Standard "unit keys" found in some databases may not be sufficient for MakeMKV's decryption method.
MakeMKV is case-sensitive on certain file systems (especially Linux, and sometimes quirky on Windows depending on how it calls the filesystem). The standard convention for MakeMKV specifically is . On some systems (like Linux), it may need
| OS | Path | |---------|-------------------------------------------------| | Windows | %USERPROFILE%/.MakeMKV/ or C:\ProgramData\aacs\ | | macOS | ~/.MakeMKV/ or ~/Library/MakeMKV/ | | Linux | ~/.MakeMKV/ or ~/.config/aacs/ |
If you place the file in the folder and MakeMKV still fails to decrypt a known disc, double-check the filename casing.
Unlocking Blu-rays: The Ultimate Guide to keydb.cfg and MakeMKV
: To use these keys effectively for 4K UHD, your Blu-ray drive must be "friendly" or flashed with LibreDrive firmware . Without this, the drive’s internal security may block the software from using the keys in the keydb.cfg file. Automating the Process
