Hello Mike,

MakeMKV was unable to decrypt the following Blu-ray disc.
The disc uses a newer version of AACS (MKB v82).

AACS dump file is attached.

Disc title:

Environment:
- macOS (Apple Silicon)
- MakeMKV v1.18.2 darwin(arm64-release)
- Drive: BUFFALO BD-RE (BN12)

Log excerpt:
-------------------------------------
This disc uses newer version of AACS protection.
Saved AACS dump file as MKB_v82_...
The volume key is unknown for this disc – video can't be decrypted
-------------------------------------

Please add support for this disc when possible.
Thank you as always.

You should email those dumps to svq@makemkv.com so a key can be created for MakeMKV's built in hashed key mechanism. A few days after emailing the dump, try the disc again and if a key is available, MakeMKV will download it automatically in the background.

There is a separate second decryption mechanism that MakeMKV supports, the public KeyDB. To contribute to the public KeyDB, use the template and follow the instructions in the first post in the Public KeyDB Disc Submissions thread. Instructions for downloading the keyDB and using with MakeMKV are also in that thread.
