Fw: [iText-questions] iText to Convert Files to PDF -urgent

[Yamuna Bellana]

Dear iText list members,          Can you please tell me whether I can read a pdf file and encrypt it and overwrite the pdf file with the same name. I just want to read the pdf file and show the user the encrypted pdf without saving it to the hard disk.   This is my code   PdfReader reader = new PdfReader("test.pdf");  // retrieve the total number of pages    int n = reader.getNumberOfPages();        Document document = new Document(psize, 50, 50, 50, 50);               PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("Encypttest.pdf"));             writer.setEncryption(PdfWriter.STRENGTH128BITS, "y", "y",PdfWriter.AllowFillIn);             document.open();      // add content    PdfContentByte cb = writer.getDirectContent();    int i = 0;    int p = 0;    //System.out.println("There are " + n + " pages in the document.");    while (i < n) {       document.newPage();       p++;       i++;       PdfImportedPage page1 = writer.getImportedPage(reader, i);       cb.addTemplate(page1, .5f, 0, 0, .5f, 0, height / 2);       //System.err.println("processed page " + i);      }    // step 5: we close the document    document.close();   Here I read test.pdf file and encrypt it and save as Encypttest.pdf . I would preffer not to save the ecrypted file. without saving just show it to the user..Can you please tell me whether that is possible? if so how can I do it...   Regards, Yamuna [EMAIL PROTECTED]
