Adding password and digital signatures to PDFs in GdPicture.NET?
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?
