Marvel's Avengers Decryption Tool (Request)

[prince55]

Good News this tool decrypt main game files ( 58 GB ) and can be expanded well by xtool
Bad news the game doesn't work properly with decrypted files esp. update files ,
In brief the tool works well with files bigfile.00x.tiger , not update or ultra or languages

I'm really not going to do anything.

I don't have a good sample, someone sent over "bigfile.update1.000.002.tiger" and I had no idea what I was supposed to do with it.

So a sample is still needed

Furthermore the decryption tool doesn't seem to come with source code so coming up with a decryption tool that works with Freearc may be problematic.

I tried to reverse engineer the program and even though I am not good at this, it doesn't seem to difficult to decrypt the game though.

- The game executable must contain the keys for each file (since it needs to be able to read all the data)

- The decrypted files cannot be read by the game since it performs the decryption of the already decrypted file, thus scrambling it again.

- The encryption algorithm used here must be a fast one, since the FitGirl repack is MD5 perfect and installs in some minutes - where the files get encrypted again.

In the Fitgirl Setup installer resources of the game, there is a file that caught my attention called tiger.exe. I imagine it must be the file that encrypt *.tiger files again, but idk how to use it.
