Example 4: Encrypt a PDF file (ASP)  

   <%
     Dim NVsign : Set NVsign = Server.CreateObject("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" 
  
     Dim retVal : retVal = NVsign.EncryptPDF("c:\in.pdf", "c:\out.pdf")
     if retVal<>0 then
       Response.Write "Error code=" & CStr(retVal)
     else 
       Response.Write "Done"
     end if

I was looking for a product that could place watermarks on very large PDF files (some of them over 30 thousand pages) in as less time as possible. After testing many tools I found Neevia PDFstamp. It did the job!
