I am signing a PDF but the Adobe say the document received 1
modification after beign signed. Why ??
Below is the code I am using to sign:
private void sign(InputStream input, File generatedPdf) throws
IOException,
FileNotFoundException, DocumentException,
KeyStoreException,
NoSuchAlgorithmException, UnrecoverableKeyException {
PrivateKey pk = (PrivateKey) keystore.getKey(alias, pkPassword
.toCharArray());
Certificate[] chain = keystore.getCertificateChain(alias);
FileOutputStream out = new FileOutputStream(generatedPdf);
PdfStamper signerStamper = PdfStamper.createSignature(new
PdfReader(
input), out, '\0');
PdfSignatureAppearance sap =
signerStamper.getSignatureAppearance();
sap.setCrypto(pk, chain, null,
PdfSignatureAppearance.WINCER_SIGNED);
sap.setReason(signatureReason);
sap.setLocation(signatureLocation);
sap.setContact(signatureMail);
sap.setSignDate(Calendar.getInstance());
// comment next line to have an invisible signature
sap.setImage(Image.getInstance(getClass().getClassLoader().getResource("files/selo.gif")));
sap.setVisibleSignature(new Rectangle(700, 350, 725, 374), 1,
"cejugcert");
sap.setSignatureGraphic(Image.getInstance(getClass().getClassLoader().getResource("files/selo.gif")));
signerStamper.setThumbnail(Image.getInstance(getClass().getClassLoader().getResource("files/selo.gif")),
1);
signerStamper.close();
}
