Go up one level in this thread


If it's just the strings you want to protect, you could put them in contiguous
space and check them in-memory.  It would be harder than hacking at the fopen(3)
level (which presumebly involves checking if the first argument is the program
name, and then breaking in the caller).  However an average hacker using SoftICE
would simply find the strings and put a memory-read breakpoint on part of them,
and thereby find the protection routine.  Maybe it's necessary to encrypt the
string as well, which is getting a bit beyond it.
