Commercial discs are encrypted using complex algorithms. To decrypt a specific movie, the software needs a corresponding key. The is a structured text file (typically named KEYDB.cfg ) containing thousands of known volume keys, Media IDs, and VUKs (Volume Unique Keys) for specific disc releases. How Xreveal Uses the KEYDB.cfg File
Xreveal operates in the background of a Windows system, intercepting disc reads in real time. When a disc is inserted, the software checks its internal key sources, resolves the appropriate key using the priority chain, and then transparently decrypts the data before passing it to any application accessing the drive. This “on‑the‑fly” decryption means that the operating system and all other software on the computer see the disc as if it were unprotected—no intermediate files or lengthy pre‑processing are required.
