Remove security from a PDF (username and password) with C#

Asked by At

I have problems with some PDF documents, when it comes to remove password I have no problems (using itextsharp.dll) but what I need is to be able to open and remove that security when the pdf comes with both username and password.

If someone could help me I would appreciate it, because I do not see any information. It has to be done with C#. By the way, I know the login data, what should be done with code is to provide username, password, to open the document and save it without security.

Attached is a snapshot of the window that appears when you open the pdf.
