PdfCertificate - document does not show Certified by

[lpdinh]

Hi
I tried to use PdfCertificate followed instruction, however the outcome PDF has "Signed by" instead of "Certified by".
Not sure it is because I am using trial version.

Code: Select all

            string dataDir = "C:\\Practice\\ApposeCerifiedSignature\\ApposeCerifiedSignature\\";
            PdfDocument doc = new PdfDocument(dataDir + "input.pdf");
            String pfxPath = "C:\\Practice\\ApposeCerifiedSignature\\ApposeCerifiedSignature\\LanLocal.pfx";
            PdfCertificate digi = new PdfCertificate(pfxPath, "WayPoint");
            PdfSignature signature = new PdfSignature(doc,doc.Pages[0], digi, "demo");
            signature.ContactInfo = "TEST";
            signature.Certificated = true;
            signature.DocumentPermissions = PdfCertificationFlags.ForbidChanges;
            doc.SaveToFile(dataDir + "output.pdf");

Thank you

Hello,

Thanks for your inquiry.
The issue is not caused by the version.
Generally, when setting the "signature.Certificated" to be "true", the signature should be displayed as "Certified by". It seems that there's something wrong with the attribute. Our dev team would look into it. I will keep you informed about the progress.
So sorry for the inconvenience caused.

Sincerely,

Hello lpdinh,

How are you?
Glad to inform that "Certified by" issue has been resolved and the hotfix(Spire.PDF Pack(Hot Fix) Version:4.5.3) is available now. The code you shared before could correctly display the "certified by" at present.
