Decrypt .exe Automobilista

Post by FanaticSim »

Hello everyone. I want to learn how to decrypt a .exe. To extract the files of physics, the tire model and the suspension of the Automobilista simulator

He used the Luigi tool to unpack the AMS.exe and got 3 encrypted binary files
.link
.data
.text
He opened each of the files with programs like hexeditor but I can't find a way to extract them in readable text. I don't have much knowledge with hexadecimal editors and I don't know if it's possible to do it

Can anyone teach a tutorial / program to do it?
Is there any Luigi tool that I can use?

.link / .data / .text are PE file section names. He probably just dumped them from a PE editor.
You can use a tool like CFF Explorer to do this.

Not sure why you would want to do this though in this kind of manner.

Hello, thanks for answering.
Try Luigi tools for ISI engine files. I managed to extract the files from the .exe but they are encrypted. I have searched for information, but nobody knows how to break the encryption.
I guess it will be very difficult

Maybe each file uses a unique key. For my part it exceeds my knowledge.I can upload archives If somene want try

I'll try with CFF explorer.

Upload the bin folder and the file you're trying to decrypt, people can help if you provide the files.

Hello everyone. Here is the folder with the files I want to extract

https://mega.nz/#F!eINEiKDC!8rOIsr_nPHcOqlMfXXbi8Q

The files correspond to the .exe of the game that I decompressed.
Inside the .text file there are some lines that are readable. These are the files I'm looking for.
I want to extract the folder called GameData

More information if I use the Luigi scripts t gamestockcar_exe.bms can extract the files but they are encrypted.I think it's a good place to start
. Any help is welcome.
