About security setting of Acrobat Reade

[sa_uchida]

Hallo Support-Team

I am using the free version of Spire.Office for .NET
Even if I set the owner password of the PDF document and save the changes to the file,
Spire.PDF cannot set all the permissions to "Not Allowed".
What should I do?

Code: Select all

using Spire.Pdf;
using Spire.Pdf.Security;
using Spire.Xls;
using Spire.Xls.Converter;

namespace test.Models
{
    public class PDFReport
    {
        public void Main()
        {
            string tempFilePath = @"D:\Template\Template.xlsx";
            string tempOutPutPath = @"D:\Template\TEST.pdf";

            // load Excel file
            Workbook workbook = new Workbook();
            workbook.LoadFromFile(tempFilePath);

            // Set PDF template
            PdfDocument pdfDocument = new PdfDocument();
            pdfDocument.PageSettings.Orientation = PdfPageOrientation.Landscape;
            pdfDocument.Security.KeySize = PdfEncryptionKeySize.Key256Bit;
            pdfDocument.Security.OwnerPassword = "test";

            PdfConverter pdfConverter = new PdfConverter(workbook);
            PdfConverterSettings settings = new PdfConverterSettings();
            settings.TemplateDocument = pdfDocument;
            pdfDocument = pdfConverter.Convert(settings);

            pdfDocument.SaveToFile(tempOutPutPath);
            System.Diagnostics.Process.Start(tempOutPutPath);
        }

    }
}

Hi

Thanks for your inquiry.
The following code can set all the permissions to "Not Allowed". If you have any questions, please feel free to write it back.

Code: Select all

 
//load the document from file
PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile(“test.pdf");
//encrypt the PDF file and set all the permissions to "Not Allowed"
pdf.Security.Encrypt("open", "permission",  PdfPermissionsFlags.None, PdfEncryptionKeySize.Key128Bit);
//save the document to file
pdf.SaveToFile("Encrypted.pdf", FileFormat.PDF);
