Angry Birds Classic Series: Game Assets (*.LUA, *.JSON, *.ZIP)

[aluigi]

Use the -d or -D option

Ok. asset_groups_decrypt.lua decrypts as LZMA'ed 7z, but cannot be extracted, but if I decrypt with OpenSSL and remove the first 9 unique header bytes it extracts fine... Also after using -d, I'm finding folders called XXX.lua having the lua. -D worked for me when targeting the scripts directory. Also some LUAs are empty...

[aluigi]

Can you upload asset_groups.lua and those encrypted lua files that extract as empty?

[LolHacksRule]

http://www.filedropper.com/birdbaseclassdecrypt. Here's one of them... I decrypted them with OpenSSL to get their LUA's successfully extracted.

Can you upload asset_groups.lua and those encrypted lua files that extract as empty?

[LolHacksRule]

Here they are.

[aluigi]

If you continue to upload the empty decrypted files I can help in no way.
I need the original files.

[LolHacksRule]

Sorry about that, here's the actual files. Also some files have extra bytes in them after using the script.

[aluigi]

Script 0.1.2.
The decryption required the "CipherFinal" prefix.

[LolHacksRule]

Missed bytes for Powerup_ExtraBird.lua. It extracted fine with the script but with it, it gives 40B of data, without it, it gives 56kb of data, also that issue prevents unluac from decompiling it. http://www.filedropper.com/powerupextrabird. This also affects other files... Also how to compile with similar file size? Doing no modifications and compiling gives a bigger file.

[LolHacksRule]

Anything?

[LolHacksRule]

options.lua isn't a LZMA headered archive after decrypting, its a plain 7z.

[aluigi]

upload it because your last link is no longer available.

[LolHacksRule]

http://www.filedropper.com/options_1 and old versions (like computer) output 7z'ed files having the LUAs after decryption.

[aluigi]

Well done, script updated to version 0.1.3

I have the key for ABSW2's assets, I ripped it right from the game's memory on PC v1.5.1 since they kept encryption the same, should that be added in?

[aluigi]

Good. Added.

Angry Birds Stella asset key, I found it by doing the old way to pull encryption keys via GDB on the Android release. Should this be added?

Oh and finally, Angry Birds Friends' asset key, this won't work on CDN-sided assets or the Flash version of the game's assets.

Since updated(8.0.1), old key not work.
I tried to use openssl to decrypt and got a message:

Code: Select all

C:\Users\Administrator>openssl enc -aes-256-cbc -d -K 55534361505170413454534E56784D49317639534B39554330795A75416E6232 -iv 0 -in F:\Repository\Downloads\lua\Level766.lua -out F:\Repository\Downloads\lua\Level766.lua.dec
hex string is too short, padding with zero bytes to length

Can anyone teach me use gdb on Android?
IDA is difficult for me.

ABClassic or other game? You have to make the game's APK debuggable, clone the APK decompiled on your computer, fake Android.mk, connect your device to your computer, call NDK-GDB (from Android SDK), use breakpoints on application functions that call for loading LUA files, load a level, you should hit the breakpoint, do x/4x and x/s on the given addresses and one should give you the encryption key. The current key works fine for me, I'll try that file (and script entirely) and see if there's a problem... UPDATE: That file works fine for decryption (just delete the 9 header bytes) and open as an archive, try updating OpenSSL or use the BMS script. You can decompile with "java -jar unluac.jar level766.lua > level766_decomp.lua".
