want to insert user-defined pass-phrase

[rakhi sinha]

I am using following code to digitally sign the pdfs it is working well,but if i write phrase in place of "abcdef" password it does not work... (because i want to enter passwords of individual persons )

HttpSession session = request.getSession();
	 		String no = (String)session.getAttribute("no");
	 		HttpSession session1=request.getSession();
	 		String phrase=(String)session1.getAttribute("[u]phrase[/u]");
	 	HttpSession session2=request.getSession();
	 		String path=(String)session2.getAttribute("path");
	 		try {
	 			KeyStore ks = KeyStore.getInstance("pkcs12");
	 			ks.load(new FileInputStream(getServletContext().getRealPath("resources/"+path)),"abcdef".toCharArray());
	 			String alias = (String)ks.aliases().nextElement();
	 			PrivateKey key = (PrivateKey)ks.getKey(alias, "abcdef".toCharArray());
	 			Certificate[] chain = ks.getCertificateChain(alias);
      PdfReader reader = new PdfReader(getServletContext().getRealPath("/resources/a"+ no +".pdf"));
		FileOutputStream os = new FileOutputStream(getServletContext().getRealPath("/resources/signed"+no+".pdf"));
		PdfStamper stamper = null;
		stamper = PdfStamper.createSignature(reader, os, '\0');
		PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
		appearance.setCrypto(key, chain, null,PdfSignatureAppearance.WINCER_SIGNED);
		appearance.setReason("It's personal.");
		appearance.setLocation("foobar");
		appearance.setVisibleSignature(new Rectangle(200, 500, 290, 450), 1,"first");
		stamper.close();

Post the code that is "not working", and tell us what "not working" actually means.
