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

Aspose.PDF Product Family

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 ?
