So someone pointed out that the partially correct XOR stream retrieved from FW4.70 -> FW4.76 (see previous post) reveals a new key on FW4.86 that works up to MKBv71
Code:
| DK | DEVICE_KEY 0x38841673E2B4E05191659899606CFFB8 | DEVICE_NODE 0x0C00 | KEY_UV 0x00000A00 | KEY_U_MASK_SHIFT 0x0B ; MKBv49-MKBv71 |

@candela
cool! now people can play their blurays that use MKBv71 and lower. (assuming they have not attempted to play a >v72 disc) so here's a new basic config that implements this new device key: Code:
; KEYDB.cfg ; Processing Keys ; Device Keys | DK | DEVICE_KEY 0x5FB86EF127C19C171E799F61C27BDC2A | DEVICE_NODE 0x0A00 | KEY_UV 0x00000400 | KEY_U_MASK_SHIFT 0x17 ; MKBv01-MKBv48 | DK | DEVICE_KEY 0x38841673E2B4E05191659899606CFFB8 | DEVICE_NODE 0x0C00 | KEY_UV 0x00000A00 | KEY_U_MASK_SHIFT 0x0B ; MKBv49-MKBv71 ; Host Certificate | HC | HOST_PRIV_KEY 0x909250D0C7FC2EE0F0383409D896993B723FA965 | HOST_CERT 0x0203005CFFFF800001C100003A5907E685E4CBA2A8CD5616665DFAA74421A14F6020D4CFC9847C23107697C39F9D109C8B2D5B93280499661AAE588AD3BF887C48DE144D48226ABC2C7ADAD0030893D1F3F1832B61B8D82D1FAFFF81 ; MKBv71 ; Bluray Disc VUK Keys ; |

Partially correct XOR stream retrieved from FW4.70 -> FW4.76 (see previous post) reveals a new key on FW4.90 that works from MKBv72 up to ? (at least MKBv81, possibly higher)
Code:
| DK | DEVICE_KEY 0x861B3719B02F24BE6F1A30E2E3ABEE94 | DEVICE_NODE 0x0C40 | KEY_UV 0x00000D00 | KEY_U_MASK_SHIFT 0x0A ; MKBv72-... Last edited by candela; 27th June 2023 at 22:29. |

One "dumb" question: If I have a Blu-Ray with MKBv76, a host certificate which was revoked from MKBv72 on and a device key which is valid for at least MKBv76 - can this Blu-Ray be played back even if the host certificate is not valid anymore?

You can keep using the cert on a drive as long as no disc >=MKBv72 was ever authenticated. |

I have an old PS3 with a burnt out HDMI port. The SCART port still works.
I don't actually have a bluray to test with, but will the SCART port still output full-resolution and bitrate today? I have read for units sold after a certain date Sony fixed it so that they wouldn't, but it's not clear to me if it was made retroactive to the older units that used to be able to do so. |

SCART can only handle analog FBAS (CVBS), plus a very few of them RGB, so analog SD.

Thanks for any assistance here. Edit: I have just tried with a MKBv76 disk, and the output is now: Quote:

I think you're correct. The device node for this key should be 0x00000800.
Matching DEVICE_NODE can be derived from KEY_UV and KEY_U_MASK_SHIFT. Code:
% ./calc_dn 400 17 Device Node: 0x00000800 % ./calc_dn a00 0b Device Node: 0x00000C00 % ./calc_dn d00 0a Device Node: 0x00000E00 Last edited by mick0; 31st October 2023 at 14:42. |
