While not "encryption," these are the foundation of the database:
In Xreveal, the decryption key database refers to the system the software uses to locate the keys required to decrypt Blu-ray, UHD, and HD DVD discs. Xreveal follows a specific "top-to-bottom" hierarchy to find these keys: keydb.db > keydb.cfg > AACS Auth > Cloud Decryption. Decryption Hierarchy
Xreveal attempts to decrypt a disc by searching for keys in the following order:
keydb.db (Local "My Discs" Database): This is the highest priority. It is a local SQLite database (typically at C:\ProgramData\Xreveal\keydb.db) where Xreveal Pro automatically saves information for discs you have already processed.
keydb.cfg (External Key File): If the key isn't in the local database, Xreveal looks for a keydb.cfg file. This file must be provided by the user (often downloaded from community sources) and contains known Volume Unique Keys (VUK) or Unit Keys (UK). Default Path: %APPDATA%\aacs\keydb.cfg. xreveal decryption key database top
AACS Auth: Attempts standard AACS authentication if local keys are missing.
Cloud Decryption: The final fallback for Xreveal Pro users. If local files fail, the software retrieves the necessary decryption data from a cloud server. Database Management
For Free Users: You must manually maintain a keydb.cfg file. If a key is missing, Xreveal may prompt you to search online databases like fvonline-db.
For Pro Users: The "My Discs" feature manages the keydb.db automatically, allowing for offline decryption of previously opened discs. While not "encryption," these are the foundation of
Plugins: To remove additional protections like BD+ or CSS, you must install the Xreveal Plugins separately. KeyDB - Xreveal
Even the "top" database cannot have every key. If you encounter a disc that fails to decrypt:
For the uninitiated: Xreveal is a Windows-based optical disc decryption tool that sits between your drive and your ripping software (MakeMKV, AnyDVD, CloneBD, etc.). Unlike all-in-one suites, Xreveal focuses on key management and on-the-fly decryption without forcing a specific ripping workflow.
Its core asset? The Xreveal Decryption Key Database (DKDB). In Xreveal , the decryption key database refers
If you want to leverage the #1 decryption key database, follow this setup guide:
Many tools only handle DVD CSS keys. Xreveal handles:
Xreveal exposes its key database via a diagnostic panel (right-click tray icon → Key Database Viewer). Here you can:
This transforms the DKDB from a black box into a forensic tool for disc ripping failures.
AMI is the market leader in BIOS firmware. XReveal supports several key structures:
