The keydb.cfg file is a community-maintained database used by MakeMKV and other media software to decrypt Blu-ray and 4K UHD discs. While MakeMKV primarily uses its own "hashed keys" system that updates automatically, the keydb.cfg file acts as a vital secondary source for decryption keys—especially for new releases or when MakeMKV's internal servers are inaccessible. What is KeyDB.cfg?
The keydb.cfg file is a standardized text file that contains decryption keys for thousands of Blu-ray and UHD titles. It includes specific identifiers like Disc IDs and Volume Unique Keys (VUKs), which software uses to bypass AACS protection.
Hashed Keys vs. KeyDB: MakeMKV typically downloads "hashed keys" automatically when you open a disc. However, keydb.cfg allows you to manually provide keys for discs not yet in the official MakeMKV database. keydbcfg makemkv
UHD Support: For 4K UHD discs, keydb.cfg is particularly useful if you have a "friendly" drive and want to rip a brand-new title before the developer adds it. Where to Download KeyDB.cfg
The most common source for this file is the FindVUK Online Database, a community resource where users upload keys from their own discs. The keydb
KeyDB is an open-source, high-performance NoSQL database that is compatible with Redis. It is designed to be fast, scalable, and easy to use. KeyDB supports many of the same data structures and commands as Redis, making it a popular choice for developers who need a robust database solution without the cost or constraints of traditional relational databases.
MakeMKV can automatically update its keys by pointing to an online repository. This is the preferred method as it keeps the keys current without manual file replacement. Open MakeMKV
