Security failure in PDF documents

PDFCreator PDFCreator English
1

I am using PDFCreator 1.2.1 on Windows7. I was shocked to discover that the security settings for Disallowing users to copy/modify/comments/etc do not have any effect! I have been happily sending "protected" documents to people without realizing that the security is not working!

Note for the sceptics: I am using an owner password to protect the document and digital signatures to sign it. I opened the document in PDFXchange Viewer 2.0 as well as Adobe Acrobat 9.0. The document properties shows everything is allowed! And I could actually modify the document using PDFXViewer.

Anybody??

I have been able to get it to work with the following setting:

.cOption("UseAutosave") = 1
        .cOption("UseAutosaveDirectory") = 1
        .cOption("AutosaveDirectory") = sPDFPath
        .cOption("AutosaveFilename") = sPDFName
        .cOption("AutosaveFormat") = 0    ' 0 = PDF
        
        .cOption("PDFUseSecurity") = 1
        .cOption("PDFOwnerPass") = 1
        .cOption("PDFOwnerPasswordString") = sMasterPass

        .cOption("PDFDisallowCopy") = 1
        .cOption("PDFDisallowModifyContents") = 1 ' Must be a 1
        .cOption("PDFDisallowPrinting") = 0
        .cOption("PDFAllowScreenReaders") = 1
        .cOption("StandardAuthor") = "Auto Generator"

        .cOption("PDFUserPass") = 0
        .cOption("PDFUserPasswordString") = "" 'sUserPass

        'To change to High encryption
        .cOption("PDFHighEncryption") = 1
       
        ' I have added
        .cOption("PDFAllowFillin") = 0  ' Must be 0
        .cOption("PDFAllowAssembly") = 0
 

Along with these setting I had to go to PDFCreator and set the PDF Format Security page to the following:

Use Security

Very High Encrytion level

Passwords Required to change permissions and passwords

This seem to work for me.

Lol, I figured out the BUG. The security settings fail if you also use the Signing option! I was using the security options as well as signing the document with my digital signatures. The moment I removed the signing, the security settings started working. Obviously a bug. I hope someone from PDFCreator is reading this and wil correct this bug soon.

 I have found the same problem with the digital signature : security options do not work. I'm using Windows 7 and PDFCREATOR 1.2.3.

Another problem : Default positions values place the signature at bottom left of the PDF. I would like it at top center.

What values have to be specified to do that ?

Thanks for your help

Same problem here with 1.2.2 on Windows XP, SP3.
