Prevent generated PDFs from further modifications
Reply Quote

Hi,

My company uses ASP.NET PinPDF v2.0.

Is it possible to protect the generated PDFs from being modified later? We generate contracts and we don't want anyone to change the content.

The problem is that with Acrobat Professionnal (for exemple) the generated PDFs can be edited and modified. Can we protect it ?

Thanks!

Hi,

you should be able toprotect the document by specifying a password.

Thanks for your answer but my problem is a little bit more complicated:

1) PinPDF is able to define 2 types of passwords:

   -> the "User Password" which is asked when the user wants to open the generated PDF in acrobat reader or acrobat professionnal.

   -> the "Owner Password" which is asked if the user already opened the document with acrobat PROFESSIONNAL and wants to change certain properties of the document (for exemple the restrictions like Modifying, Printing, Sign etc.)

2) Indeed, my question is: with PinPDF, is it possible to change the restrictions of the PDF document? In my case, I would like to set the Modifying restriction to "Non authorized" so nobody can edit and modify the contracts that we generate as PDF documents.

 

Best regards,

Nicolson

Nicolson,

point 2 is unfortunately not possible right now.

You might consider using one of the passwords.
