You didn't specify what operating system you're using so I will assume that its a unix-like OS like Linux. In that case, the popen() could be used to run the command line md5sum program against your target program. > I need to create a program which check md5 of another program, if checksum > match with one memorized the program will be exec. There is still a possibility of a BadGuy replacing the program after the md5sum is calcuated but before you exec it.
