MakeMKV 1.10.12 released, fixes bugs in Ultra HD Blu-ray disc dump feature

Posted 04 February 2018 16:20 CEST by Jan Willem Aldershoff

The developer of MakeMKV released an update for his software today. Version 1.10.12 fixes bugs related to the software’s hashed keys function that allows MakeMKV to rip all available Ultra HD Blu-ray discs. Due to the bugs, dumps of several discs were not correct and therefore MakeMKV supports less discs than actually possible.

Recently MakeMKV added support for so-called ‘hashed keys‘. These keys are different from the leaked AACS 2.0 keys and the MakeMKV developer is able to retrieve the hashed keys from dumps users send to him.

The ‘hashed keys’ are one way compatible with the leaked AACS 2.0 Volume Keys. The latter can be converted to ‘hashed keys’ but ‘hashed keys’ can’t be converted to AACS 2.0 Volume Keys. Since the previous version, MakeMKV is able to read both types of keys from a single file. The author makes a regularly updated file available that contains all his hashed keys and the leaked AACS 2.0 Volume Keys.

However, the dump function appears to have contained a bug, as the developer writes, “all versions before 1.12.0 have various nasty bugs in code responsible for UHD AACS20 dump generation. Please switch to 1.12.0 . If you ever sent UHD MKB20 dumps, never heard back, but your disc did not appear in hashed keys – that was probably due to these bugs.”

The developer asks users who suffered from the bug to submit their dumps again.

More information about MakeMKV can be found on their website. You can download the software from this page. MakeMKV is available for Windows and Mac. MakeMKV is free while it’s beta but expires after 60 days. To reset the expiration date it’s possible to download the software again.
