    random.Next(0, 16).ToString("x"),
    "6",
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x"),
    random.Next(0, 16).ToString("x")
}).ToLower();
