Protect your files against unauthorized changes [ C++ Source ]

[quyen194]

If one player injects a speedhack.dll, will it change the crc of the the target file? Because if it will, then putting a crccheck on files will block speedhacking, won't it?

If speedhacking is made by change player.bmd, this crc-files-checking can prevent that problem
But you need to create a thread for checking interval time, because before choose character they can change bmd file
The only way to bypass this is killing the checking thread LOL

it seems it is possible to modify / edit a file and obtain same crc32 (do not know how, navossoc did this, but without keeping the same file size), so i implemented a checkFilesSize function to avoid this:

add in checkcrc.h:


add cFile.cpp to project:


add cFile.h to project:



modify dllmain.cpp

how to use this all in vs2010????
