There was some rumour a very long time ago that the player keys are not true 128-bit, and once you know that a certain part of the keys always followed a pattern then the key strength was more like 60-bit or something like that, which is quite easily hacked, and if that is the case then Redfox would in fact know all the player keys, however many there are. They know if they release them all the players have their keys revoked and firmware updated, and therefore that's why they don't put them in the program. I think Slysoft hacked a bunch of players and know many of the player keys. MakeMKV does it the same way AFAIK.Īlthough companies claim their disc keys can't be hacked from players, that isn't at all true. Safely eject the SD card from the computer. Make sure the files are not in a folder on the SD Card. Drag/Copy the files over to your SD Card drive. In your file explorer (PC) or finder (Mac), locate the downloaded firmware folder. Redfox has a way to decrypt the media keys - but AFAIK the software doesn't do that, rather it downloads the media keys from the internet and then uses them to decrypt the disc (this way preventing others from working out how Redfox decrypts the media key). Step Three: Load the 2 files onto a formatted SD card. Of course if you had 1 billion very fast computers then it would only take 1 year. It isn't possible to decrypt the disc in any other way because brute-force would take something like a billion years for a very fast computer. Xreveal 2023 allows you to unprotect encrypted DVD/Blu-ray discs. The way AACS encryption works is that the media key (the decryption key) is encoded on the disc dozens or hundreds of times (once for each authorised player) and can be decoded using a "player key" that in turn gives the player the decryption key to then decrypt the disc.

Every decryption key that encodes the disc is unique to each released disc (it's also called the "media key).
