-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I've got the same problem with the timestamping code but in fact, while
trying to get a small example together, I've found that the same error
occurs also with just the signing part.
The signing code is based on the doc to sign doc at:
http://itextpdf.sourceforge.net/howtosign.html#howtosign
The two pdf files are attached.
The Java code consists of:
=========
com.lowagie.text.Document.compress = false;
KeyStore ks = KeyStore.getInstance("pkcs12");
ks.load(new FileInputStream(KEYSTORE), PASSWORD.toCharArray());
String alias = (String)ks.aliases().nextElement();
PrivateKey key = (PrivateKey)ks.getKey(alias, PASSWORD.toCharArray());
Certificate[] chain = ks.getCertificateChain(alias);
PdfReader reader = new PdfReader(IN);
FileOutputStream fout = new FileOutputStream(OUT);
PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0');
PdfSignatureAppearance sap = stp.getSignatureAppearance();
sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
sap.setReason(REASON);
sap.setLocation(LOCATION);
// comment next line to have an invisible signature
sap.setVisibleSignature(new Rectangle(100, 100, 200, 200), 1, null);
stp.close();
=========
