How to view .obb files? (specifically images)

[Google]

Found out how to view the acb files, you can open them with VGMToolbox, then extract and you get .hca

They seem to be an audio file, open with mpv and you can hear the audio.

Thats nice, but it seems the images, sprites, png etc has md5 encryption, and I have no idae how to decrypt that. Anyone might know? Open the .db file with tools like "DB Browser for SQLCipher", you can see its encrypted with some kind of hash. But I digged into it and might have found out they might use TexturePacker & md5 encryption
