The DVDFab Passkey application was developed to be a Windows-based driver that works on-the-fly to unprotect encrypted movie DVDs and Blu-ray discs. For DVD, it removes all DVD copy protections, like CSS, CPPM, RC, RCE, APS, UOPs, ARccOS, RipGuard, FluxDVD, CORE X2, etc. For Blu-ray, it removes all known AACS and BD+ copy protections, Region Code, BD-Live and UOPs.
