On the surface, they serve completely different purposes. However, advanced media server setups (e.g., Jellyfin, Plex, or Emby with hundreds of discs) may use a database to:
Make sure you are using a "hashed" KeyDB if you are using an official UHD drive, or a standard one if you have a "LibreDrive" flashed firmware. 🚀 Automate Your Workflow Tired of manual downloads? Many users use or specialized scripts to automatically sync the latest
r = redis.Redis(host='localhost', port=6379, decode_responses=True)
MakeMKV is incredible, but it doesn't always have the decryption keys for every single disc ever released. The Database: keydbcfg makemkv
This is the most common point of failure. You cannot place the KEYDB.cfg file just anywhere. It must go into MakeMKV's dedicated "data directory."
The configuration file keydb.cfg is the backbone of modern Blu-ray decryption in MakeMKV. It contains thousands of Universal Disc Format (UDF) volume keys and Video Title Set (VTS) keys. These keys allow software to bypass Advanced Access Content System (AACS) protection.
Why keys_hashed.txt ? MakeMKV expects a hashed key format. The raw KEYDB.cfg uses a different standard (VUK). However, modern ripping utilities (like FindVUK or DVDFab) include a "Hasher" tool. Alternatively, you can rename the file, but it is safer to copy the contents: On the surface, they serve completely different purposes
The file is UTF‑8 encoded without a BOM. It supports comments beginning with a semicolon ( ; ). The structure includes four types of entries:
You might ask, "Isn't MakeMKV enough?"
MakeMKV users are likely more familiar with . These are small files provided by the MakeMKV community that contain the specific decryption data for a specific disc version (e.g., a 4K UHD release from a specific region). Many users use or specialized scripts to automatically
This is where comes into play.
Before we tackle the configuration file, let's establish the primary software. is a commercial (but currently free while in beta) application designed to convert video discs into MKV containers.
