Toaru Majutsu no Index: Imaginary Fest mesh files and Textures

[Rinaldi104]

Happy Valentine Days to all of you
I hope everyone here get a chocolates

Recently i've been working to look any toaru index imaginary fest files with my phone unfortunately i've got a solution with using Bluestacks and rooted with bluestack tweakers.
Based the other post i've got game files inside data/data/com.square_enix.android_googleplay.index_if
I manage to get those files and try to opened with Asset Studio but it failed
Someone said that it is encrypted with simple 1-byte xor key
So the question is
Is there anyone know how to solve this encryption and also get a texture files from this games

There is a script made for this.

Thank you andree
You're life saver

Thank you andree
You're life saver

did you manage to encrypt them?

[Rinaldi104]

Actually i got them already

Actually i got them already

all files? Most of my files have not been decrypted

After a night of brain burning, I found that most of the files XOR to 0x100, and then loop. After further analysis, I guess that there are 1024 decryption schemes for the files, two of which are not encrypted or spam themselves (but you can delete them manually). They all have plaintext: unityfs, and one of the remaining 1022 is viewtopic.php?f=16&t=21917&p=171560&hil ... st#p171560 Use only one byte encryption，I only manually decrypted a few keys, which are only useful for a few files. I also decrypted the "b20e38b5" in the root directory, and found the details that seem to be the decryption scheme? I don't know the code. So I'm not sure.Looking at the installation package, I found that the company has another game I am playing:Nier Re[in]carnation，I have reason to believe that Nier uses the same encryption method。（Please forgive my grammar, it comes from the translation engine）

And this

Hello, it's me. Again, I think I've found a certain rule. Look at this:

I listed the bytes of some files from 0x7 to 0xa. Guess what? xor.key Changed with it! And it's cyclical! Sorry about my explanatory power.. For example: file a, byte 0x7-0xa is 00537b43, its first XOR key is 47, and file B, byte 0x7-0xa is 537b4385 (do you see it? The XOR key 47 is the last! File C, byte of 0x7-0xa is 7b43859a > >....... Cycle!

Actually not all the files that i've got there
It seems Decrypted somehow
Can't figure it out actually
My mind is blowing

Hello libaibaba thank you for your hard work
It seems i can't understand about your explanation
What i can get is the xor key might be 47
I don't know it work as well to another files
But if your theory was right
We might be able to makes a script for those files
