Dawn of War II Unlockable Content, part 2
This post addresses a few of the questions which have arisen since part 1:
"can you put file to rapidshare" (and similar requests)
I'm here to point out flaws in Relic's security chain. I'm not here to give everyone quick and easy access to the pre-order content, so I will not be posting the modified files myself.
"Well done there, though the question of how long this will be possible for, how much data the Steam client collects about the programs it runs (DLL hashes are pretty standard, or?) and what Relic's views on this might be still remain."
Hashing of DLLs is fairly standard; for example, if you modify SimEngine.dll (perhaps to add a maphack), then you can't join online games as your hashes won't match those of the other players. However, as wincrypt.dll is not a DLL which comes with the game, it is not hashed by default. Furthermore, as it is a Windows DLL, it will (probably) change with each Windows version and/or service pack and/or patch, meaning that it cannot be reliably hashed.
"How do I find where this function is which I need to replace the first five bytes of?"
There are tools which list all exported functions of a DLL and their virtual positions, i.e. the position in virtual memory (relative to the DLL base) at which you will find the function when the DLL is loaded into memory. Converting this virtual position into a physical position, i.e. the position in the file on disk of the function, can be done by analysing the DLL's PE section table in a suitable tool.
"I don't see anything about UnlockMask in the content.bin, do you have any more specific instructions for this?"
The contents of content.bin can be viewed in two ways; calling dofile("content.bin") in a Lua interpreter and then printing the resulting DLC table, or running content.bin through luac: (lua and luac are both part of the official Lua.org package)

Once you've looked at the contents of the file, it is trivial to load it into a hex editor and replace the 1, 2, 4, 8, 16 and 32 strings with 0, 0, 0, 0, 00 and 00 respectively.
