Example 4: Encrypt a PDF file (Delphi)  

   uses ComObj;

   procedure TForm1.Button1Click(Sender: TObject);
     NVsign : Variant;
     retVal : Integer;
     NVsign := CreateOleObject('Neevia.PDFsign');

     NVsign.PDFEncrypt := true;
     NVsign.PDFEncryptionType := 'rc4';
     NVsign.PDFOwnerPassword := 'owner';

     // p - document printing is denied
     // e - disable extraction of text and graphics
     NVsign.PDFPermissions := 'pe';
     retVal := NVsign.EncryptPDF('c:\in.pdf', 'c:\out.pdf');
     if retVal <> 0 then
       Application.MessageBox(PChar('Error code=' + IntToStr(retVal)),'',0)

As a programmer I needed a tool to manipulate PDF files. Neevia PDF toolbox contains everything necessary to build a solution that can be used to stamp, split, merge, resize and compress PDF documents, all from one package!
