Xreveal: Decryption Key Database

Think of it as a massive, ever-growing keychain for the digital locks on DVDs, Blu-rays, and UHD Blu-rays. Every time a studio releases a disc with new copy protection (AACS, BD+, CSS, etc.), the disc is essentially a safe with a unique combination. The Xreveal database stores the master keys, device keys, processing keys, and volume unique keys needed to unlock that safe — instantly and legally (for personal backup, where permitted).

The Xreveal Decryption Key Database is not static. New movies are released weekly, and studios can revoke compromised keys (issuing MKB versions that blacklist older keys). Therefore, keeping your database updated is critical.

| Tool | Database Format | Update Frequency | UHD Support | Automatic Upload | |------|----------------|------------------|-------------|------------------| | Xreveal | .xrdb (encrypted) | Weekly | Full | Built-in disc dump | | AnyDVD HD | .zip (online only) | Bi-weekly | Full | No (separate tool) | | MakeMKV | Built-in (SVQ files) | Monthly | Partial | No | | FindVUK | Plain text .txt | Community | Full | Yes (to public forum) |

Xreveal’s advantage:

The movie industry is not standing still. New 4K Blu-rays are starting to use AACS 2.1, which introduced "One-Time Programmable Memory" (OTP) keys. In theory, this means each drive has a unique key, making a universal decryption key database impossible.

However, history shows that no DRM survives contact with dedicated enthusiasts. The Xreveal development team is actively researching:

For now, the Xreveal Decryption Key Database remains the most effective, community-driven solution for backing up physical media. As long as a single software player (like PowerDVD) or a single hardware player’s keys are leaked, the database will continue to grow. Xreveal Decryption Key Database

The Xreveal Decryption Key Database is a structured repository of cryptographic keys, device-specific identifiers, and volume unique keys (VUKs) used to unlock AACS-protected Blu-ray discs. In simpler terms, it is a digital lockbox.

Each encrypted disc contains a set of "locked" assets. To unlock them, you need a specific key. That key is unique to each title (and sometimes each pressing of the disc). The Xreveal database stores millions of these keys, indexed by the disc’s unique identifier (known as the Volume ID).

The database is not a monolithic, opaque file. It typically exists in two forms: Think of it as a massive, ever-growing keychain

The developer of Xreveal periodically aggregates submissions, cleans duplicate entries, validates keys against known good hashes, and pushes an official database update. This update is optional—you can choose to stay offline and manually manage your key database.

With an active Xreveal subscription, the software automatically downloads the latest keys from Xreveal’s servers every few days. This is the "set it and forget it" method.

Even with a robust database, problems occur. Here are the most common Xreveal decryption errors and how to fix them. The movie industry is not standing still
