A university film library owns 500 Blu-ray discs that are no longer manufactured. Several discs from 2008 use AACS version 1.0 with BD+ version 1. Legacy software fails because the old keys have been revoked by newer MKB updates. Xreveal’s historical key database retains retired Processing Keys and Host Private Keys, allowing the archivist to bypass revocation checks—a feature unique to Xreveal’s top-tier database architecture.

Xreveal. Its database is larger than MakeMKV’s built-in key set and updates more granularly than AnyDVD’s monolithic .ZIP updates.

: Used primarily by the free version, this text-based file must be manually downloaded and placed in the %APPDATA%\aacs\ folder.

For the vast majority of users, the "top" database is the one integrated directly into the software.

The default location for the key database is: C:\Users\[YourUsername]\AppData\Roaming\aacs\ .

If you prefer storing your large databases on secondary drives, you can easily point Xreveal to a custom destination:

When you search for "xreveal decryption key database top," you are likely looking for the .

A law firm had 500 encrypted ZIP files from a legacy backup. Instead of brute-forcing each, the IT team used Xreveal’s database. After cracking the first 10 files (using mask attack for [A-Z][a-z][0-9] pattern), the database recognized the pattern—all files used the same base key plus a date suffix. Decryption time: 5 minutes.

4K UHD discs use dynamic keys. If your database file is more than a few weeks old, it will likely lack the keys for brand-new cinematic releases.

: You must manually maintain a keydb.cfg file. If a key is missing, Xreveal may prompt you to search online databases like fvonline-db.
