[walidrezzouqi]

Hello,

Code: Select all

 var page = docpdf.Pages[0];
            X509Store x509Store = new X509Store(StoreLocation.CurrentUser);
            x509Store.Open(OpenFlags.ReadOnly);

            byte[] test = Encoding.ASCII.GetBytes(docpdf.ToString());

            X509Certificate2Collection x509Certificate2Collection = x509Store.Certificates.Find(X509FindType.FindByIssuerName, "Baridesign", false);
            X509Certificate2 x509Certificate2 = x509Certificate2Collection[0];

Hello,

Thanks for your post. You could transform the X509Certificate2 into PdfCertificate and use it directly. Please refer to the below code snippet. In addition, please use the latest version(Spire.PDF Pack(Hot Fix) Version:4.4.6).

Code: Select all

            PdfDocument pdfDocument = new PdfDocument();
            pdfDocument.LoadFromFile(@"C:\Users\Administrator\Desktop\1copy.pdf");
            var page = pdfDocument.Pages[0];

            X509Store x509Store = new X509Store(StoreLocation.CurrentUser);
            x509Store.Open(OpenFlags.ReadOnly);

            byte[] test = Encoding.ASCII.GetBytes(pdfDocument.ToString());

            X509Certificate2Collection x509Certificate2Collection = x509Store.Certificates.Find(X509FindType.FindByIssuerName, "Baridesign", false);

            X509Certificate2 x509Certificate2 = x509Certificate2Collection[0];
            PdfCertificate digi = x509Certificate2 as PdfCertificate;

            PdfSignature signature2 = new PdfSignature(pdfDocument, page, digi, "demo");
            signature2.ContactInfo = "Simon";
            signature2.Certificated = true;
            signature2.DocumentPermissions = PdfCertificationFlags.AllowFormFill;
            signature2.Bounds = new RectangleF(new PointF(0, 0), new SizeF(200, 90));

            pdfDocument.SaveToFile("result.pdf",FileFormat.PDF);
            System.Diagnostics.Process.Start("result.pdf");
