Creating a pdf using aspose occur error the existing digital signature

I created pdf again with digital signature using aspose. But when I open the pdf file again, the digital signature is breaked.

when I create from filestream to pdf using aspose, use this source in c#.

Aspose.Pdf.Document pdfDocTemp = new Aspose.Pdf.Document(fileStream);

Aspose.Pdf.Document pdfDoc = new Aspose.Pdf.Document();

int tempPagecnt = pdfDocTemp.Pages.Count;
for (int tempPageCount = 1; tempPageCount <= tempPagecnt; tempPageCount++)

var pdfStreamNew = new MemoryStream();
