How to set PDF security

About PDF security

A PDF file may be encrypted for security, or digitally signed for authentication.
The standard security provided by Acrobat PDF consists of two different methods and two different passwords, "user password" and "owner password".
A PDF document may be protected by password to open ('user' password) and the document may also specify operations that should be restricted even when the document is decrypted: printing, copying text and graphics out of the document, modifying the document, or adding or modifying text notes and AcroForm fields (using 'owner' password).
PDF document security should not be used as primary way of securing sensitive data, all operations (except the document open password protection, if applicable) which are restricted by "owner" or "user" passwords can be easily cracked by third party applications.
Even without removing the password, most freeware or open source PDF readers will ignore the digital rights management "protections" and will allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection.
Swing PDF Converter provides basic PDF document security, this includes:
  • User password
  • Master password
  • No printing
  • No changing the document
  • No content copying or extraction, disable accessibility
  • No adding or changing comments and form fields

User password

Authenticated user rights:
  • Decrypt PDF document
  • Read PDF document
  • Other rights are defined by master user.

Master password

Master user rights:
  • Change user rights
  • Decrypt PDF document
  • Read PDF document
  • Print PDF document
  • Modify PDF document
  • Extract data from PDF document

Setting PDF Security from Lotus Notes

PDF Security can be set from "PDF Settings" view in the PDF Converter database.

Setting PDF Security from LotusScript API

The following article article explains how to set Swing PDF Converter API in custom application:

LotusScript sample code

Use "SwPDFMain"
Sub Click(Source As Button)
Dim w As New NotesUIWorkspace, doc As NotesDocument
Dim swPDF As New SwPDFCreator, swPDFDoc As SwPDFDocument, pdfErr As SwPDFError
Dim DestFilePath As Variant
On Error Goto Ooops
If w.CurrentDocument.IsNewDoc Then
Msgbox "Document must be saved first in order to convert it to a PDF.", 0+48, "WARNING"
' Get destination file path
DestFilePath = w.SaveFileDialog(False, "Save document", "PDF Files (*.pdf)|*.pdf", "", "test.pdf")
If Not Isempty(DestFilePath)Then
If Dir$(DestFilePath(0)) <> "" Then
dialogRes = Messagebox(DestFilePath(0) & " already exists." & Chr$(13) & Chr$(10) & "Do you want to replace it?", 4, "Save document")
If dialogRes = 7 Then
Exit Sub
Kill DestFilePath(0)
End If
End If
' Procceed with PDF conversion
' Get currently opened Notes document
Set doc = w.CurrentDocument.Document
' Initialize PDF creation process; license key is required
' enable font embedding for non ascii characters
swPDF.PDFSettings.EnableFontEmbedding = True
' Set PDF document security
swPDF.PDFSettings.UserPassword = "User"
swPDF.PDFSettings.MasterPassword = "Master"
swPDF.PDFSettings.Enable128bitEncryption = False
swPDF.PDFSettings.EnablePrinting = False
swPDF.PDFSettings.EnableChanging = False
swPDF.PDFSettings.EnableCopying = False
swPDF.PDFSettings.EnableComments = False
swPDF.PDFSettings.EnableFormFields = False
' Convert doc to PDF
Set swPDFDoc = swPDF.ProcessDocument(doc)
If Not swPDFDoc Is Nothing Then
' Finally, save generated PDF to a file on disk
Call swPDFDoc.SaveToFile(DestFilePath(0))
Msgbox "PDF successfully created in " & DestFilePath(0)
' There was an error in PDF conversion
Set pdfErr = swPDF.GetError()
Msgbox pdfErr.Message, 0+16, "ERROR"
End If
' There was an error in PDF initialization
Set pdfErr = swPDF.GetError()
Msgbox pdfErr.Message, 0+16, "ERROR"
End If
End If
End If
Exit Sub
Msgbox "Error: " + Error + " On line: " + Erl
Exit Sub
End Sub
