I used a binary reader on an EXE file. At that start there's the usual "This program must be run in win32" thingy, then there's a bunch of stuff I don't get. After that, a lot of 0s. Then the real codes. I understood the binary codes with the help of Intel manual, but the header, everything before the codes, I don't get. What is in there?

Oh, and I used Hexplorer V2.6 to read the files if that's relavant.

Thanks, Boucly.

Thanks and nice to see someone around, Igorok!!! This forum had been quiet lately, but its holiday, what can you do about it. *Sigh* Then again, there isn't that much things in assembly which hasn't been asked already. Oh, and for your webpage, I am going to read it later since school starts in three days and well I haven't started my coursework that's due in the first day back. Do you know any good binary reader too?

Binary reader Hiew is the one of favorite tools of crackers.

Cracker? How could a binary reader be useful to a cracker?? And why would they use it? I am a bit curious *smile*, but DON'T answer that, especially not in a forum. A binary reader can't turn binary into assembly codes, can they?. Anyway, I just want to know what to write in the header bit when I somehow get the wild idea of making a compiler in the future. I know I will because some newbies in other forums said they had wanted to as the advanced through assembly and I am quite possibly going to be one of them. I am quite predictable.

One more question, would the binary reader also work on other files like bitmap files, because there was a pattern when I tried to read bitmap files in notepad.

Cheers *wink*, Boucly

Using a binary reader cracker can patch the files.
>A binary reader can't turn binary into assembly codes, can they?
It can. Hexplorer as far as is known has also a disassembler.
>One more question, would the binary reader also work on other files like bitmap files
Sure. You should only know this format.
