public static string ReadPassword()

    char[] revisekeys = new char[3];
    revisekeys[0] = (char)0x08;
    revisekeys[1] = (char)0x20;
    revisekeys[2] = (char)0x08;
    
    StringBuilder sb = new StringBuilder();
    while (true)
    {
        ConsoleKeyInfo kinfo = Console.ReadKey(true);
    
        if (kinfo.Key == ConsoleKey.Enter)
        {
            break;
        }
    
        if (kinfo.Key == ConsoleKey.Backspace)
        {
            if (sb.Length != 0)
            {
                int rIndex = sb.Length-1;
                sb.Remove(rIndex, 1);
                Console.Write(revisekeys);
            }
            continue;
        }
        sb.Append(Convert.ToString(kinfo.KeyChar));
        Console.Write("*");
    }
    return sb.ToString();
