Reading a password from std::cin

@wrang-wrang answer was really good, but did not fulfill my needs, this is what my final code (which was based on this) look like:

#ifdef WIN32
#include <windows.h>
#else
#include <termios.h>
#include <unistd.h>
#endif

void SetStdinEcho(bool enable = true)
{
#ifdef WIN32
    HANDLE hStdin = GetStdHandle(STD_INPUT_HANDLE); 
    DWORD mode;
    GetConsoleMode(hStdin, &mode);

    if( !enable )
        mode &= ~ENABLE_ECHO_INPUT;
    else
        mode |= ENABLE_ECHO_INPUT;

    SetConsoleMode(hStdin, mode );

#else
    struct termios tty;
    tcgetattr(STDIN_FILENO, &tty);
    if( !enable )
        tty.c_lflag &= ~ECHO;
    else
        tty.c_lflag |= ECHO;

    (void) tcsetattr(STDIN_FILENO, TCSANOW, &tty);
#endif
}

Sample usage:

#include <iostream>
#include <string>

int main()
{
    SetStdinEcho(false);

    std::string password;
    std::cin >> password;

    SetStdinEcho(true);

    std::cout << password << std::endl;

    return 0;
}
