How to create SID like S-1-5-21-123697389-1196883430-1112475604-1016 in windows c++
In Windows, the SID (Security Identifier) is a unique identifier used to represent a security principal, such as a user or group. Creating a SID involves using the Windows API functions. Here's an example of how you can create a SID like "S-1-5-21-123697389-1196883430-1112475604-1016" in C++:
cpp#include <Windows.h>
#include <Sddl.h>
#include <iostream>
int main() {
// Variables to store the SID components
DWORD sidIdentifierAuthority[6] = {0x5, 0x15, 0x78, 0x12, 0x34, 0x56};
DWORD sidSubAuthority[4] = {123697389, 1196883430, 1112475604, 1016};
// Create the SID
PSID pSid = nullptr;
if (!AllocateAndInitializeSid(
reinterpret_cast<PSID_IDENTIFIER_AUTHORITY>(&sidIdentifierAuthority),
4,
sidSubAuthority[0],
sidSubAuthority[1],
sidSubAuthority[2],
sidSubAuthority[3],
0,
0,
0,
0,
&pSid))
{
std::cout << "Failed to create SID: " << GetLastError() << std::endl;
return 1;
}
// Convert the SID to string
LPWSTR sidString = nullptr;
if (!ConvertSidToStringSidW(pSid, &sidString)) {
std::cout << "Failed to convert SID to string: " << GetLastError() << std::endl;
FreeSid(pSid);
return 1;
}
// Print the resulting SID
std::wcout << "SID: " << sidString << std::endl;
// Clean up resources
LocalFree(sidString);
FreeSid(pSid);
return 0;
}
Make sure to link against the Advapi32.lib
library by adding it to your project settings.
This code snippet uses the AllocateAndInitializeSid
function from the Windows API to create the SID and the ConvertSidToStringSidW
function to convert it to a string representation. The sidIdentifierAuthority
array represents the identifier authority part of the SID, and the sidSubAuthority
array contains the sub-authority values.
After executing this code, you should see the resulting SID printed, which should match the desired format "S-1-5-21-123697389-1196883430-1112475604-1016".
