AACS v82 dump - Japanese Blu-ray Disc

Post by milkylucky »

Hello,

I tried to back up a Japanese Blu-ray disc with MakeMKV v1.18.1,
but it failed to decrypt. The log says:

"This disc uses newer version of AACS protection.
Saved AACS dump file...
Disc volume label code unknown - failed to decrypt."

I am attaching the AACS dump file generated by MakeMKV
(MKB_v82_Another.tgz).

Hopefully this can help update the key database.
Thank you! ! :)

Please don't try and attach dump files here.

The process is to email the tgz dump file to svq@makemkv.com so Mike can add a key for it to MakeMKV's hashed keys. Additionally, if you would like to also help the community, you can upload the dump file to a host somewhere, such as goolge drive, one drive, mediafire etc then post the download link here.
Cheers :D

Thank you for the reminder! I’ll send the tgz file to the email address as suggested.
