Passkey Lite is a free version of Passkey, which is a Windows-based driver that works on-the-fly to decrypt encrypted movie DVDs and Blu-ray discs. With the help of Passkey Lite you can remove copy protection and region code from DVDs and Blu-rays which can then be accessed by any media player such as VLC Media Player, WinDVD and PowerDVD. It also allows third-party tools like Imgburn and Nero Recode to burn/recode the copy protected DVDs into non-copy protected discs that can be played back in DVD or Blu-ray players.
Once you insert your DVD/Blu-ray into the optical drive, Passkey automatically takes over. It checks if the disc is region locked or copy-protected. If restrictions are found, Passkey will remove it. After a short while, you will get the unprotected disc in your drive, which can play with players like PowerDVD, WinDVD, TotalMedia Theatre, etc. The process usually takes just a minute or two.
Sometimes you may be asked to specify the DVD disc's region code to remove RCE limitation. You can also check how many protections and which ones Passkey found and removed in Settings/Info window.
DVD ripping is also provided along with Passkey Lite. Right click on the program’s icon in the notification tray and choose "Rip to Hard Disk" or "Rip to Image", the former saves the content of the disk to the hard drive as a folder, while the latter saves it as an ISO image file.
The DVD protections which can be removed by Passkey Lite are RC (Region Code), CSS (Content Scrambler System), RCE (Region Code Enhancement), APS (Analog Protection System), and UOPs (User Operation Prohibition). For Blu-ray, it can mange AACS V10(Advanced Access Content System), RC, BD-Live, and UOPs. Some copy protections cannot be removed in Passkey Lite such as AACS V12+, BD+, BDAV, and AVCREC for Blu-ray. It doesn't support CPRM for DVD, and PathPlayer is not enabled, so ARccOS, RipGuard, can't be removed. As a result, you can't copy those DVDs, but you are able to freely watch them.
