Public MKBs

Are there security or law-related complications about publishing MKBs found in Blu Ray disks one buys? Are there publicly downloadable copies of the last MKBs? Is it allowed to post them on this forum?

I own just a few Blu Ray disks, all of them with very old MKBs. If it is allowed, I would thank you if someone could share the latest MKB available from one of your disks (it is the file AACS/MKB_RO.inf in the disk). I managed to get the private host key from a couple of players and would like to know whether they are revoked or not.

I believe there is nothing prohibiting MKBs to be published. However, to save space, here's the host revocation list for MKBv61:
Code:
  0x000000000001 - 0x0000000003E8
  0x000080000001 - 0x0000800080E8
  0x270F80000001 - 0x270F80000BB8
  0xFF2210100001 - 0xFF221010001F
  0xFF2210400001 - 0xFF221040001F
  0xFF2220000001 - 0xFF22200000FF
  0xFF2290100001 - 0xFF229010001F
  0xFF2290400001 - 0xFF229040001F
  0xFF22A0000001 - 0xFF22A00000FF
  0xFF2318000001 - 0xFF231800001F
  0xFF2318100001 - 0xFF231810001F
  0xFF2318400001 - 0xFF231840001F
  0xFF2340000001 - 0xFF23400000FF
  0xFF2710000001 - 0xFF271000001F
  0xFF2790000001 - 0xFF279000001F
  0xFFFF0000000B - 0xFFFF00000014
  0xFFFF00000016
  0xFFFF00000021 - 0xFFFF0000002A
  0xFFFF00000035 - 0xFFFF00000038
  0xFFFF0000004E - 0xFFFF00000052
  0xFFFF00000054 - 0xFFFF00000057
  0xFFFF0000005D - 0xFFFF00000066
  0xFFFF00000080
  0xFFFF00000088 - 0xFFFF00000091
  0xFFFF00000094
  0xFFFF000000AE
  0xFFFF000000B2 - 0xFFFF000000BB
  0xFFFF000027DB
  0xFFFF00002817
  0xFFFF00002820
  0xFFFF00002834 - 0xFFFF0000283D
  0xFFFF00002846
  0xFFFF0000284B
  0xFFFF80000001 - 0xFFFF80000024
  0xFFFF80000029
  0xFFFF8000002F
  0xFFFF80000039
  0xFFFF80000045
  0xFFFF80000071
  0xFFFF80000079
  0xFFFF8000007C - 0xFFFF8000007E
  0xFFFF800000AD
  0xFFFF800000C4 - 0xFFFF800000C6
  0xFFFF800000D0
  0xFFFF800000F4 - 0xFFFF800000FD
  0xFFFF80000146
Just check certificate ID and you'll see if it is revoked or not. Note that host private keys aren't particularly interesting, they can be easily extracted. The one I've posted some time ago on this forum still works up to MKBv61 (MKBv62 was released since then, but I don't know if it was revoked there or not).

For testing purposes, I made a collection of MKB_RO.inf files and dumped the HRL and DRL lists. Download links: MKBv01-64 & HRL_DRL_MKBv01-64

For some reason, MKBv26 cannot be dumped by libaacs. I tried several different discs. However, the HRL and DRL are identical to MKBv27. Also, it appears these MKB versions were never released: 02, 05, 11, 13, 29, 41, 45, 59. If you have any disc with these versions please post.

Public MKBs

Where do you save this information to?
Does this mean we can watch MKBv65 movies?

No, it means you don't want to insert a MKBv65 disc in your drive if you want to keep using the revoked certificate (should you have the key for it). The data in this thread is only for information/testing purposes, it does not contain anything you can use to enable playback
