Code to hash MK11's data in order to properly send requests to the api endpoints. VR Hash check is introduced on 15th of September 2020.
- You need to use the provided Cheat Table in order to obtain the 4 IV values from the game. Should Enable the script while the game is loading but before you "Press Start".
- Get the IV Values and the string you want to hash.
Usage Command is
vr-hasher IV1 IV2 IV3 IV4 String_To_Hash
I'm retrieving the 4 IVs after they're being calculated from 1 initial IV. This is because the 4 IVs are in the registers at a specific point during execution, which is less prone to change during updates than trying to retrieve from the stack. (mov $data, RAX is less prone to update than mov RAX, [ESP+20]). The point of obtaining the code uses AOB scan over a function that theoritically doesn't change, so it should work across new updates as well. Finally, the address of this pointer that stores the IV struct is 0x143176620 as of Sep-15-2020. IV Struct is at addr+0x1390, which translates to 0x1431779B0. The initial (seed?) value is at IV Struct + 0x20 which is used to create the other 3 values, and the remaining the 3 IV values are at RSP+0x70 RSP+0x88, R11.
