Bump for the new encryption of Minecraft Store Packs instead of the deprecated encrypted ZIPE format: http://www.zenhax.com/viewtopic.php?f=9&t=7190

I want to view the data in some packs acquired from the Minecraft Store (premium_cache in AppData) but most is unreadable, upon MANY lookups, the data is encrypted and devs stated that many times too. They previously had most of the pack in the contents.zipe format with only that being encrypted (given by ZIPE, ZIP Encrypted, also having the pack UUID in the header) while everything outside was readable fine, but was then deprecated as of sometime and they now have the entire pack completely pre-decompressed (from a ZIP archive from the CDN), but with the majority of assets encrypted. Audio files are sometimes encrypted, textures and most scripts are ALWAYS encrypted. They are pre-encrypted from distributors from the CDN. If anyone wants to crack open the files, I give so much thanks.

Notes on them:
1. Does not write to the system decrypted anywhere in the process.
2. Cannot be loaded plain in "games/com.mojang"'s (external) folders as decryption code doesn't take effect here (encrypted worlds created from encrypted world templates with packs are decrypted in the memory fine, otherwise you will output many content log errors if you try to load them all externally).
3. Can use decrypted assets over encrypted.
4. MOST packs are hidden from the user (in the game) unless loaded in a world template or the skin editor.
5. They all have an Xbox ownership check to prevent using the content unowned (unless free).
6. Key is singular (I think).
7. You may rename content folders downloaded and extracted in AppData then load them that way, decryption won't be affected.
8. Renaming UUIDs messes up content locating.

Any luck yet?

No not yet, also if you read the memory of the game, you can see the decrypted assets, just not the encryption key(s)...

Uhhh... I wouldn't call the "first 16 bytes of a PNG file" decrypted assets. Also, it looks to be very very fragmented.
