        var loadOptions = new LoadOptions { Password = "1234" };

        try
        {
            using (var metadata = new Metadata("path/to/your/password-protected-document.docx", loadOptions))
            {
                // Your code to manipulate or read metadata goes here
                Console.WriteLine("Document loaded successfully!");
            }
        }
        catch (Exception ex)
