Hi,
this seems to work very well, but how can I send a request with libssh ? Actually, I would like that libssh go through tor Network, and reach a .onion service, but I don't know how to do that... Do you have any idea ?
Thanks !

Greetings!

Thanks for this peace of code but you forgot to startup winsockets with WSADATA.

WSADATA wsaData;

int iResult;

// Initialize Winsock
iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (iResult != 0) {
	std::cout << " [*] WSAStartup failed " << iResult << std::endl;
	return 1;
}

you need to have tor running on the computer ,this just uses the proxy on the computer that tor setups up, its not tor
