PE File Format question
by null_endian- 1 reply
- 3.8k views
In the PE file format, there is the DOS_HEADER and then right after that, there is a section called doscode which is by default 64 zero bytes. However, sometimes it is filled with an arbitrary number of bytes. Some PE files have a lot of bytes here, others don't. How can I calculate the number of bytes that doscode will be? There doesn't seem to be any field in the DOS header which specifies this. Thanks.

Speed optimization question: Having this code: F1_bak = F1_bak+An+Mn[0]; // add the already computed Mn[0] value unsigned int lr_val1_bak = leftrotate(F1_bak, s[0]); unsigned int Ban1Test = Ban[0]+lr_val1_bak; if (Ban[1]!=Ban1Test) { //printf("Invalid Ban[1] value!!!!\n"); goto StartOfSearch; } versus second one: unsigned int Ban1Test = Ban[0]+leftrotate((F1_bak+An+Mn[0]), s[0]); if (Ban[1]!=Ban1Test) { //printf("Invalid Ban[1] value!!!!\n"); goto StartOfSearch; } It happens that the first one is faster, there is more code to it and the difference is of 10 seconds! Can someone explain why?

Could anyone please shed some light on me about the process of creating an exe (outputting a compiled exe) from another exe? Like the loader/patcher programs, you put the name of the program you want to patch, put addresses and bytes, then click some "create patcher" button and the patcher-creator program outputs a patch.exe for you. Or like the keylogger or rat programs, after selecting desired settings, you click some "create server" button, and it outputs a server.exe for you. I am somewhat lost about how this process is done, tried googling but couldn't find any source to learn (maybe I don't even know how to search on this topic). For starter, I want to make an …

Hi guys, today I check some of my windows sockets codes and wanted to update & optimze it a little writing some clean code without to be messy to have also a better view on it.Now I came to the hostent struct which returns a pointer to this struct after calling gethostbyname / gethostbyaddr.Now in the MSDN description I can read that this struct is only used once for each call to this function and getting overwritten by another call.Now they say I should copy the struct into other buffer. So does it mean I dont need to copy it into extra buffer if I call the function from diffrent created threads?Just if I use same thread = copy to buffer?So normaly I ca…
