ks.load(new FileInputStream("c:/temp/sign.pfx"),

String alias = (String) ks.aliases().nextElement();
PrivateKey key = (PrivateKey) ks.getKey(alias,
"password".toCharArray());
Certificate[] chain = ks.getCertificateChain(alias);
PdfReader reader = new PdfReader("c:/temp/in.pdf");
FileOutputStream fout = new FileOutputStream("c:/temp/out.pdf");
PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0');
PdfSignatureAppearance sap = stp.getSignatureAppearance();
sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
sap.setReason("iText");
sap.setLocation("Espana");
sap.setContact("Alberto");
sap.setVisibleSignature(new Rectangle(100, 100, 200, 200), 1, null);
stp.close();
}
}
I have been doing several tests but I do not find where the mistake is.
Thanks
