There is one further issue when using the Encryption:
As soon as I create a protected PDF with
lPdf := TPdfDocumentGDI.Create(false, 0 , false, TPDFEncryption.New(elRC4_128, '', 'password', PDF_PERMISSION_NOMODIF));
the data entered in the document´s TPDFInfo like
lPDF.Info.Author := 'Auto Generated Document';
lPDF.Info.Creator := 'XYZ GmbH';
can no longer be displayed properly in Adobe Acrobat or any other PDF reader.
Did anyone successfully use TPDFEncryption without this issues?

Hi,
I am trying to generate a password protected PDF that cannot be modified w/o password like so:
lPdf := TPdfDocumentGDI.Create(false, 0 , false, TPDFEncryption.New(elRC4_128, '', 'password', PDF_PERMISSION_NOMODIF));
When I open the PDF in LibreOffice Draw I am prompted for the password, but may click Cancel or enter a blank password and the PDF is still opened and can be modified.
What am I doing wrong?
Thanks!
