1. /*Code for adding digital signature to pdf*/
   // Load the document
   PDFSecure pdfDoc = new PDFSecure ("input.pdf", null);
   
   // Load the keystore that contains the digital id to use in signing
   FileInputStream pkcs12Stream = new FileInputStream ("keystore.pfx");
   KeyStore store = KeyStore.getInstance("PKCS12");
   store.load(pkcs12Stream, "store_pwd".toCharArray());
   pkcs12Stream.close();
   
   // Create signing information
   SigningInformation signInfo = new SigningInformation (store, "key_alias", "key_pwd");
   
   // Create signature field on the first page
   Rectangle2D signBounds = new Rectangle2D.Double (36, 36, 144, 48);
   SignatureField signField = pdfDoc.addSignatureField(0, "signature", signBounds);
   
   // Apply digital signature
   pdfDoc.signDocument(signField, signInfo);
   
   // Save the document
   pdfDoc.saveDocument ("output.pdf");
