getestet unter xp-32 und win7-64.

für interessierte, das c(++)-programm:

#include "stdafx.h"
#include <conio.h>
#include <iostream>
#include <string>


int _tmain(int argc, char* argv[])
{
	using namespace std;
	if (argc < 2) {
		cout << "usage read_passwd <passwd>\n";
		return 0;
	}
	

	string password;
	char ch;
    	const char ENTER = 13;
	const char BS = 8;
	cout << "enter the password: ";

    while((ch = _getch()) != ENTER)
    {
	if (ch == 3) { // ctrl-c
		return 0;
	}
	if (ch == BS) {
		if (password.length() > 0) {
			password = password.substr (0, password.length() -1);
			cout << BS << " " << BS;
		}
		continue;
	}
        password += ch;
        cout << '*';
    }
	cout << "\n";
	return strcmp (argv[1], password.data()) == 0;
