I want to view the PAK files of the games, but I think they are encrypted or compressed in a way I cannot understand... Anyone willing to decompress these or find the encryption keys for me?

Upon reading the memory, I got the filelist for both games:

https://www.angrybirdsnest.com/wp-conte ... l1fups.PNG

https://www.angrybirdsnest.com/wp-conte ... 9n65yd.PNG

Others only have few JSONs and XMLs.

Dammit. Welp, the game's ActionScripts are obfuscated, making it harder to pull the keys and possible encryption mechanism from them... http://www.zenhax.com/viewtopic.php?f=9&t=11382

Here's better links:

Ok so I'm trying to datamine Angry Birds Breakfast's assets, unfortunately they are in troublesome PAK files which are also likely encrypted, it is a Flash game. Can someone get the encryption key to crack these? The dev's also obfuscated the game's SWF file...
Links:
1: https://drive.google.com/drive/u/1/fold ... L941U1dGVD
2: https://drive.google.com/drive/u/1/fold ... drive_open
SWF: https://drive.google.com/open?id=1ZD2UA ... kreWLS8juJ (both games use the same file)

Upon painfully deobfuscating Breakfast using the secure_map xml file, I eventually found the PAK/package decryption code. It's not a string or anything easy but can someone derive the key/mechanism from it? Thanks. It appears to use a library called deng.FZip in relation to opening the files. It's possible this could be the same for other AB Flash titles using PAKs like Friends, Breakfast 3, Heikki, Eagles and so on.
