Sign PDF files with A3 USB certificates and put a stample on every page

Hi, I´m evaluating ASPOSE.PDF for .NET.

What my client needs is:

1) Check a lot of files on my root folder to see if the file is digitaly signed. If not, sign digitally the pdf file using a A3 Certificate.
2) Put a stample on every page (Image) indicating that that file was digitaly signed.

Is this possible to achieve with aspose.pdf component ?



Hi there,

Sorry for the delayed response. You can easily check whether a PDF document is signed or not, digitally sign and add image stamp to PDF documents using Aspose.Pdf. Please check following documentation link for details.
