Latest Assetto Corsa Encryption

[delumrc]

Hello everybody,
has anyone else encountered problems in decrypting the latest Assetto Corsa files? In particular, i'm talking about the data.acd file.
quickbms successfully extract the archive in many ".ini" and ".lut" files, but these are still encrypted.

This, for example, happened to me when extracting porsche files or Lamborghini ones.

ex. lamboghini_huracan_gt3
power.lut

,u=)/.47&34,46}.9/762t.:2=,38x,6@ÿ,97,}=4.23(.ƒ+6>

That can happen only if you moved data.acd from the original location.
The reason is that the encryption key is calculated on the name of the folder, so it must be the original one.

Thank you so much!

Hi, I also got same similar problem when extracting the data.acd on a modded car.

Whenever I try with Assetto Corsa Tuner Program or with QuickBMS the .ini and .lut files ends up like this.

Example: Pontiac_Firebird_81 (by Uncle M)
power.lut

7v145
740|.35
10/3‚1:;
1<*0|17220-.|185

This one looks a bit different and almost complete compared to delumrc's example

The problem is simply in the name of the folder which contains also some uppercase chars (like "Pontiac" instead of "pontiac"), till now all the samples were lower case

Just updated the script to version 0.1.1a:
