When attempting to encrypt a pdf, I get a zero size file as a result. Any ideas what is causing this?
File f = new File("C://secure_abc.pdf"); FileOutputStream out = new FileOutputStream(f); PdfReader reader = new PdfReader("C://abc.pdf"); System.out.println("reader.getFileLength(): "+reader.getFileLength()); PdfStamper stamp = new PdfStamper(reader, out); stamp.setEncryption(null, null, PdfWriter.ALLOW_PRINTING, PdfWriter.ENCRYPTION_AES_128);
Please add the following line at the very end:
You created a zero-length file when you do this:
FileOutputStream out = new FileOutputStream(f);
But no bytes are written to that output stream up until you close the
