无法从内存中清除winhttp变量 [英] Can't clear winhttp variables from memory

问题描述

兄弟，



如何从WinHttp api中清除变量？



我使用codecave来打电话给winhttp api，但我想隐藏网址。我已经调用了RtlZeroMemory但是网址仍然可见...



可以使用kernel32.RtlZeroMemory清除变量吗？可以从用户模式调用kernel32.RtlZeroMemory吗？



我不知道从编解码器中清理内存。



提前感谢，



我尝试过：

 if（hConnect）
 hRequest = WinHttpOpenRequest（hConnect，LPUT，
 L/writetst.txt，
 NULL，WINHTTP_NO_REFERER，
 WINHTTP_DEFAULT_ACCEPT_TYPES，
 0）; 

解决方案

您必须只搜索，阅读和理解HttpOpenRequest文档说：



调用应用程序完成后使用WinHttpOpenRequest返回的HINTERNET句柄后，必须使用WinHttpCloseHandle函数关闭它。

 WinHttpCloseHandle（hRequest）; 
 hRequest =  0 ;  //  制作它清楚 

我留给你自己找到关闭连接句柄。 ; - ）

hi brother,

How to clean variable from WinHttp api?

I use codecave to call winhttp api but I want to hide the url. I have called RtlZeroMemory but the url is still visible...

Can Variables be cleared with kernel32.RtlZeroMemory? Can kernel32.RtlZeroMemory be called from user mode?

I have no idea to clean up memory from codecave.

thanks in advance,

What I have tried:

if (hConnect)
        hRequest = WinHttpOpenRequest( hConnect, L"PUT", 
                                       L"/writetst.txt", 
                                       NULL, WINHTTP_NO_REFERER, 
                                       WINHTTP_DEFAULT_ACCEPT_TYPES,
                                       0);

解决方案

You must only search, read and understand the in HttpOpenRequest documentation which says:

"After the calling application finishes using the HINTERNET handle returned by WinHttpOpenRequest, it must be closed using the WinHttpCloseHandle function."

WinHttpCloseHandle(hRequest);
hRequest = 0;//to make it clear

I leave it to you to find the closing of the connection handle yourself. ;-)
