Xreveal Decryption Key Database |link| (Deluxe)

Xreveal Decryption Key Database is a collection of disc-specific keys (like VUKs or Media Keys) used by the software to decrypt Blu-ray, UHD, and HD DVD media.

For the free version of Xreveal, users must manually provide a file to enable decryption. Key Database Files Xreveal utilizes two primary types of database files:

: A public text file containing decryption keys for thousands of discs. Since Xreveal does not provide this file directly, users typically download it from community sources like the FindVUK Online Database : A local database used by Xreveal Pro (stored in C:\ProgramData\Xreveal\

) that automatically saves information for every disc you process, allowing for offline decryption in the future. Setup and Locations To use a decryption key database with , place the

file in one of the following default locations or specify it in the software settings: Standard Location C:\Users\[YourUsername]\AppData\Roaming\aacs\ Alternative Location C:\ProgramData\aacs\ Settings Path : Open Xreveal and navigate to Settings > BD / UHD > KeyDB to manually set the path to your database file.

How to use Xreveal

The Xreveal Decryption Key Database is a critical external component that enables the Xreveal software to decrypt Blu-ray, UHD, and HD DVD media. Unlike some all-in-one decrypters, Xreveal's free version does not include built-in decryption keys; instead, it relies on a user-provided text file, typically named KEYDB.cfg, to unlock protected discs. Key Components and File Formats

Xreveal utilizes two primary types of databases to manage decryption keys: Xreveal Decryption Key Database

KEYDB.cfg (User-Provided): A text file containing disc keys (VUK/UK) for various Blu-ray and UHD titles. Users must download this file from third-party community sources and point Xreveal to its location.

keydb.db (My Discs Database): An internal SQLite database used primarily by Xreveal Pro. It automatically records keys for discs that have been successfully processed, allowing for offline decryption of previously opened discs without needing the external .cfg file. Search Priority for Decryption

When a disc is inserted, Xreveal follows a specific hierarchy to find a matching decryption key: keydb.db: Checks the local "My Discs" history first.

KEYDB.cfg: Searches the user-specified external configuration file.

AACS Auth: Attempts local authentication via AACS libraries.

Cloud Decryption: Pro version users can retrieve keys from an online cloud database. Setup and Configuration Xreveal Decryption Key Database is a collection of

To use the decryption key database with the free version of Xreveal, follow these steps:

Download the Database: Obtain a current KEYDB.cfg file from community forums or databases like the FindVUK database.

Standard Location: By default, Xreveal looks for this file in %APPDATA%\aacs\ (usually C:\Users\[Username]\AppData\Roaming\aacs\).

Custom Pathing: You can change this location by navigating to Settings > BD / UHD > KeyDB within the Xreveal application and browsing to your downloaded file.

Plugins: To support CSS (DVD) and BD+ protections, users must also install the Xreveal Plugins separately. Benefits of the Key Database KeyDB - Xreveal

🛡️ Why It Matters

Preservation: Without it, millions of discs would become unreadable as players fail and DRM servers shut down.
Convenience: No more hunting for cracked .exe files or using outdated rippers.
Transparency: You see exactly which keys are being used — no black boxes.

4.3 Backup and Portability

The database file can be copied between installations. Useful for offline machines: 🛡️ Why It Matters

Backup C:\ProgramData\Xreveal\keys\*
Restore on another PC → same decryption capability.

Part 8: The Future – Xreveal and the Post-AACS World

As of 2025, AACS 2.1 (an incremental update for 4K discs) is slowly being deployed. Newer discs are using enhanced BD+ protections. The cat-and-mouse game continues.

The Xreveal Decryption Key Database’s open architecture positions it perfectly for the future. Unlike closed-source competitors, Xreveal can quickly integrate new key types:

AACS 2.1 support is already in beta via user-extracted Host Certificates.
Advanced BD+ virtual machine emulation is being added to the driver, requiring no database changes for BD+—only more powerful key extraction tools.

Furthermore, the database format is being extended to support disc signatures for damaged media—a feature that would allow the database to store not just decryption keys but also error-correction metadata for scratched discs.

The "Auto-Key Retrieval" Trick

If you have a disc that Xreveal cannot decrypt, and you have access to MakeMKV (which is free while in beta), you can:

Run MakeMKV to open the disc (which often finds keys online).
Then, in Xreveal, go to Tools > Import Keys from Running Process. Xreveal will extract the keys from MakeMKV’s memory and add them permanently to its own database.

This feature is groundbreaking—it turns third-party software into a key source for Xreveal.

3.2 Database Update Workflow

Xreveal does not automatically "crack" new discs. Instead:

Users upload disc dumps (via Xreveal’s built-in "Create Disc Dump" feature) to the Xreveal community or key collectors.
Key contributors (using specialized tools like FindVUK or DVDFab's key extractors) generate the missing VUK.
The Xreveal maintainer updates the central key database.
The new database is published as an encrypted .xrdb file.
Xreveal client downloads and merges it automatically (or manually via Tools → Update Keys).

⚠️ Legal note: In many jurisdictions, distributing AACS keys is a violation of the DMCA / EUCD. Xreveal’s database is hosted outside high-enforcement regions.
