Doesn't look like you need to download the hashed keys file manually anymore. MakeMKV will download the necessary info on its own.
Makemkv download (pretty straight-forward to install): http://www.makemkv.com/download/
Update: Starting from version 1.14.0 MakeMKV can read UHD discs using any BDXL-compatible LibreDrive drive - that includes most "official" and all "friendly" UHD drives.

Old, but still useful stuff:
So this has gotten to be pretty straight-forward. Per the instructions _HERE_
save the referenced text file into the folder in Makemkv that you've designated to be the "data directory" (step 3 below) and, using MakeMKV 1.10.10 or later and a UHD friendly drive, you then can rip a UHD movie, assuming that the hashed key has been uploaded to that file already.
This is actually really straight-forward if you've already been using Makemkv... Also, it looks like Redfox is actively updating their software to include these keys.

So we were using Volume Keys. MakeMKV is now set-up to use hashed keys. In terms of the data directory in the next step, it's the same. However, you'll want to just completely get rid of the volume keys and replace them entirely with the hashed keys: http://s000.tinyupload.com/index.php...99194347240305
(If this doesn't work it can be found in the directions at the beginning of this post) This is a file that you will need to periodically update as it is updated. Note that just because a movie is in the list, it does not mean you have the same version of the movie. You'll notice that there are multiple hashed keys for the same movie--there may be more hashed keys that have not yet been uploaded to the file. For example, while I have successfully ripped quite a few 4K movies, I cannot yet rip Baby Driver. There is a method for pulling the info they need to get the hashed key for your particular volume but I have not gotten there yet.
To manually add hashed keys keys to makemkv, you open Makemkv, go to view->preferences, then, ->general and establish a folder for the "makemkv data directory". In that newly established data directory folder, create a (plain) text file and paste those codes and all their info into the text file. Mine is named keys.txt and I made it with notepad. (If that does not work for you, try renaming it to be a .cfg file)
If you wish to remux the Atmos track from a 4K UHD disc with the 3D video file from a 3D blu-ray, the process is the same that we have covered before: https://www.avsforum.com/forum/39-ne...y-quality.html
Now I finally have Pacific Rim in 3D and Atmos!!!
