GdPicture Imaging Forums

Hello, I am currently using GdPicture.NET for PDF document processing, and I would like to know how I can add password protection and digital signatures to my PDF documents. Can you please provide me with guidance or documentation on how to implement these features using GdPicture.NET SDK?

Hi there,

This should be very straight forward to implement on your end so please let me know if you have any issues with trying either of these out.
