Hi all, While playing with the Miracl large integer package and using the example code as a base, i made 3 ECDSA functions: 1. Keypair generation. 2. Data signing. 3. Signature verification. Using the 'cinstr' function i am able to load parameters from ascii strings to bignum variables and it works just fine, all 3 functions are operational and correct. Using the 'big_to_bytes' function i am able to get the octet string which represents the bignums in use and i can load them back to bignum variables using 'bytes_to_big' and following along in OllyDbg i can see that all of the values are correct and exactly the same as if i had loaded them from strings. However, when it re…

I created a simple oval png and used it as the frame window of my application. I noticed that some patch used pnglib and UpdateLayeredWindow to realize regioned and transparent window. Any buddy could fix my code? Thanks a lot. Here's the main code: //UpdateLayeredWindow using Visual Studio 2003 above //or VC6 with upgraded SDK, tools->options->directories //set include path of newer SDK case WM_CREATE: PNG_Init(&g_pnginfo); PNG_LoadResource(&g_pnginfo, g_hInst, MAKEINTRESOURCE(IDR_PNG_FRAME)); PNG_Decode(&g_pnginfo); g_bmpHandle = PNG_CreateBitmap(&g_pnginfo, hwnd, PNG_OUTF_AUTO, false); PremultipliedAlpha(g_bmpHandle); return 0; case WM_PAINT: hdc…

I'd like to retrieve all the windows having same class name "tooltips_class32" I used the win32 API function: hwndFound = FindWindowEx(NULL, NULL, "tooltips_class32", NULL); However, I could get only one window. Question is how to get all windows having the same class name. Another question is how to get the tooltip text? Using GetWindowText API, right? Thank you!

Memory Sizes
by Bit_Hacker- 2 replies
- 10.1k views
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…
