Hi, It's a good idea to add an encrypted hello world example. Though I do not have much time right now, so hope I it is enough, if I send you a smaller example via e-mail.
The first step is to construct a PdfEncrypt object which can either be passed
to PdfStreamedDocuments constructor or be set on a PdfDocument using
PdfMemDocument::SetEncrypted( const PdfEncrypt & e ).
To create a PDF file with an owner and user password and which only allows
printing the document you could use the following code with
PdfStreamedDocument:
PdfStreamedDocument writer ( argv[1], ePdfVersion_1_5,
&PdfEncrypt( "user_password", "owner_password",
PdfEncrypt::ePdfPermissions_Print ) );
or for PdfMemDocument:
PdfMemDocument doc;
// ... do something ..
doc.SetEncrypted( PdfEncrypt( "user_password", "owner_password",
PdfEncrypt::ePdfPermissions_Print ) );
doc.Write("test.pdf" );
By the way, I should note that AES encryption does not work yet.
best regards,
Dom
