[kickstart]

Has anyone something new about rf2 decryption?

Hi Aluigi,

Can you do a quick a view on this? I believe you can do it and decrypt the .mas file of the rFactor2, if you need any help don't hesitate to contact me.

Thank you very much for the great work.

[kickstart]

up again... Will be fine.

Since 2017 summer popular rFactor2 contents like a GT car have released with new encryption.
Now we have 16 GT & Prototype cars and 2 tracks with that

I bought all those DLCs.
If you want to know whether a car has proper physics you need to analyze physics files inside DLC.
But I can't check inside files now
It would be nice to have the new decryption tool for rFactor2

Well, the error mentioned by the OP was easy to solve, just changed the first HEX pattern on line 11 of rfactor2.bms. Checking with XVI32 it showed it to be \xCE\xFE\xF7\xCB\xCA\x7D.

But after that, I get this error:

Code: Select all

Error: incomplete input file 0: C:\quickbms\encrypted_dlc.mas
       Can't read 1747164357 bytes from offset 08d29d98.
       Anyway don't worry, it's possible that the BMS script has been written
       to exit in this way if it's reached the end of the archive so check it
       or contact its author or verify that all the files have been extracted.
       Please check the following coverage information to know if it's ok.

  coverage file 0    99%   148020622  148020632  . offset 08d29d98

Last script line before the error or that produced the error:
  27  log MEMORY_FILE BASE_OFF SIZE

Not sure what to do from here. Tried to find this offset on XVI32, found a few "D2 9D 98"s but none with 08 preceding. Also, couldn't find anything to make me understand the role of the MEMORY_FILE there, and where all that date came from.

If anyone could shed a light, I'm interest in going forward with this.

Sadly, i cant help, but many thanks to going forward with that! Hopefully Aluigi will have a look into...

any news?

Hi guys, any news on the decription of the new Rfacto2 cars and tracks?

thanks for the reply

[GikoHanyan]

I saw the cracked rFactor2 with DLCs which used new the decription system on a Russian forum.
But we can not undecription files alone on that version.

We Modder need seriously the method which can undescript the new rFacotr2 system.
I hope a talented person develops new method and releases it

[LoSte7]

Hi GikoHanyan

why we can not undecript the file?

can you please link the russian forum you found?

thanks a lot

[GikoHanyan]

Hi, LoSte7

Check the following link.
https://cs.rin.ru/forum/viewtopic.php?f=10&t=64323&start=2010
You must sign up the forum to see the link.

But that uploaded version makes no sense to Modder.
Yes, using that version you can play with decrypted DLCs that you don't have. And that is all. You can not decrypt new style encrypted files.

Anyway seeing that forum will help you.

[LoSte7]

Thanks a lot GikoHanyan

i'll write in to ask if someone is able to do that, maybe we can have some help from them

i'll post an answer as soon as i have it

[Modder]

[LoSte7]

bad news for the moment Guys, no positive answer in the Russian forum

i post also a proposal in the market section of this forum, i can pay if someone will be able to do that

hope to find a solution asap
