====== Blu-ray DRM ======

  * [[Blu-ray]]

Similar to DVDs, which use CSS, Blu-rays use AACS for their DRM. There are two ways you can bypass it. Using [[libaacs]] and a ''[[KEYDB|KEYDB.cfg]]'' file, or using [[MakeMKV]] which bypasses it completely.

Note that for UHD discs (4K), I've never gotten FindVUK to work on them, you will have to use MakeMKV.

==== Getting Key Files For libaacs ====

There are two ways to get a key for a Blu-ray: you can download one or crack it yourself. Best place to download one is from [[http://fvonline-db.bplaced.net/]]. I **occasionally** will back theirs up, and keep it here: [[https://bluray.beandog.org/keydb/]]

On Windows, you can use [[FindVUK]] to access the disc and extract the key using a program called DVDFab.

Once you have a ''KEYDB.cfg'' file with the required entries, [[libaacs]] will look for it in the ''.config/aacs/'' directory from your home directory.

Here's what a sample entry would look like:

<code>
0x123456F8974109DEB7281DCFG80BCDB182903BCD = MOVIE TITLE (Movie Title) | D | 2021-07-13 | U | 1-0x3456F8974109DEB7281DCFG80BCDB182 ; MKBv72/FindVUK 1.57</code>

[[VLC]] will look for this file to access the Blu-ray and play it back. If you have Java installed, you can also view the menus.

==== Using MakeMKV ====

If you don't want to deal with finding keys, you can use [[MakeMKV]] instead, and ignore them completely. MakeMKV has its own way of bypassing DRM. The program runs on Linux and Windows. See the [[MakeMKV|wiki page here]] for details on using it. It is partially open source software, so if you want to use completely free software, you'll have to use libaacs above.
