Crystal export to PDF, possible to add password?

Question

Using VS2005 and creating a Crystal Report, exporting it to a PDF.

 

report.SetDataSource(ds);
report.ExportToDisk(ExportFormatType.PortableDocFormat, 
fileName);
report.Dispose();

I was wondering (hoping) that there is a way to add a password to the PDF document during the export.
Thanks.
