using (var signature = new PdfFileSignature())
{
signature.BindPdf(signedFile);
foreach (var name in signature.GetSignNames())
{
Console.WriteLine("name:" + name + " State:" +signature.VerifySigned(name));
}
}
Thank you. The code does work with your example PDF.
Is there only certain types of signings Aspose.PDF can verify? Is there a way to determine if the signature is actually invalid vs Aspose just couldn’t verify?
I’ve tested the code on a number of PDFs from various sources and the only one that seems to work is your example PDF.
