Programming and Coding

I wrote a small program to explain the type sizes to myself. But while reading a few reverse engineering books I have became confused. Inside one of the chapters I ran into this statement: << The word is understood not only as 2 bytes, but also as the size of operands by default; in 32 bit mode, the word equals 4 bytes. >> like repe movsd (repeat equal) (movsd is a dword) which is 2 words. which apparently according to the text would be 8 bytes. but in my program a dword is 4 bytes... ( Please someone straighten me out... lol ) Can someone explain this to me? #include <iostream> #include <windows.h> using namespace std; int main() { cout &l…

Whenever i compile a project in WinASM studio.i get an error."failed to create....blahblah" on the bottom of my screen.when i execute it says "executing failed" Someone please help.

Hi guys. Can someone explain why AES encryption with work large files lose or adding some bytes. Original size must be : 17,9 MB (18 819 479 bytes) I get : 17,9 MB (18 819 488 bytes) here code public static void DataEncrypt(string fileIn, string fileOut) { FileStream FILE_In = new FileStream(fileIn, FileMode.Open, FileAccess.Read); FileStream FILE_Out = new FileStream(fileOut, FileMode.OpenOrCreate, FileAccess.Write);byte[] TEST_KEY = new byte[] {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10}; byte[] TEST_IV = new byte[] {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10};R…

Hi All. I need some Win32 Api functions for enum all open port (TCP, UDP, etc) that can be implemented on XP, 7, or below. is there any function that i can be used for?

Hi all, the program I'm working on allocates a block of memory of 0x66000 bytes. (Using Olly it is displayed on the Memory Map Tab) Every time I start this program it is 0x66000 bytes. Only the Base adres differs. I want to find this block of memory (if Olly can do it, It is possible) Using C# how should I do this? regards, ger

HiI got a nice keygentemplate and need transparant textboxes. I already have that but the text from the textboxes is strange... Look at the pic. Maybe someone does know how to get normal text there?

I generate some rsa keys with lockbox(c++ builder xe2) now if i whant us this keys i get an error invalid integer value: Her the keys i whant us: Puplic exponent E=EB0C Modulus N=75E7D3A2D3BC5366050B13B0D149479E8997EA705ABFE096528E9967DA0D763DCDC8B814F12BC005F08838350889832C67AFBEBCE3ECA772B8EA04F81C215A45FDC80CC29294F7E1474B656B8741AB6B8CDDB52274EF230E283F7DC4C570D855 Private exponent D=C3C37306BB25C9FFE62EE26B9393FF1986612B9A5256C5EF1A7BFEED58C3CDAB482F12DBAF751AB72C60737C3B0E0B421210A80DCF431B88ACD946A32AC7F90980E73BC6A7607E12F6133AF2D48048393C3E0AD89E0A150A3C86AB618E929B46 The keys looks like littel endian to me but i am not sure.

Hello everyone I have an EXE file packed by ASPACK. I want to write to a memory byte in real-time using asm code "mov byte ptr ds:[xxxxxxxx],xx" but when I do so, I get access violation error. I checked the EXE with some PE editors, code section flags was set to read/write/execute. so this won't gonna help me. what I need to do is, changing memory access in real time by using asm codes or any other way. when I load the EXE in olly and set memory mapping to full access, there will be no access violation error. I'll be pleased if anyone help me. thanks in advence

I was missing a comfortable way to manage complex data structures in MASM. Java coders will know the HashTable class, which is very useful to store data. i coded something similar with more functions for MASM and other programming languages. features: -it will organize memory itself (will use the windows Heap functions) -like in java you can access items via a key which can be a String or an integer -support for nested hashtables (so you can create very easy complex data trees) -save/load the hashtable to disk or memory (with nested hashtables) the example will show how to create following hashtable structure: ; ht_1 ; | ; +-0-->"hello 1" ; +-1-->"hello 2" ; …

Hey guys, Anyone having the source code to StrongOD plugin for Olly? Or can anyone tell me what Kernelmode option is doing when using the StrongOD plugin. I am in the middle of developing my own plugin that actually works on Win7 or Win8 so far most (read all) Olly plugins are failing on the new Windows versions. best regards Snoopy

Hello everyone, I was really bored and had a stupid idea: why not make a program that steals passwords from the users who use it? Before you continue reading you should know that we have about 32 computers at school who all run windows XP and require the user to log-in. The profile data is retrieved from a server and the teacher watches you (not going to sites like failblog.com) with a program called UltraVNC. To continue with this uber-lifeless post: I had the idea to make a program that looks exactly like the windows logon screen which steals passwords by storing them in a mysql database (freemysql.net). The funny thing is that the teacher behind his pc will see a login…

hi, i am writing a function in c++ (msvc2008 pro), which has to be "portable" (ie. no calls to other functions or APIs) and fast. At one point i am using something like while(tlen++ < total) *str++ = leChar;which works fine, but msvc choses to "optimize" it to a crt-memset call. :/ I generally noticed msvc is very keen on replacing code with crt calls to memset, even my custom memset-function, which uses an inlined REPMOV (and serves the sole purpose of making me independant from the crt...). Is there anyway i can turn off this specific optimization feature? I tried all sorts of linker switches; none of which worked properly.
