Thank you for your reply Paulo.
I haven't a timestamp, the acrobat reader is showing to me the warning of
the signature is from the signer's computer.
I've tried to put a null into the Signer Date with something like this...
PdfSigGenericPKCS sig = sigApp.getSigStandard();
PdfLiteral lit = (PdfLiteral)sig.get(PdfName.CONTENTS);
int totalBuf = (lit.getPosLength() - 2) / 2;
byte buf[] = new byte[8192];
int n;
InputStream inp = sigApp.getRangeStream();
try {
sig.getSigner().setSignDate(null);
while ((n = inp.read(buf)) > 0) {
sig.getSigner().update(buf, 0, n);
}
}
catch (SignatureException se) {
throw new ExceptionConverter(se);
}
But it doesn't seem to work. Any idea?
