Hello,
I follow the example from iText examples to add LtvVerification to the code
as following.
But after the PDF signed, I open with Acrobat reader, it just shows LTV not
enabled!
Anything else I need to do? I am using iText-5.4.5.
Please help.
Best regards,
Eric
tsaClient = new TSAClientBouncyCastle(TSA_URL, TSA_ACCNT, TSA_PASSW, 6500,
"sha256");
LtvVerification v = stamper.getLtvVerification();
AcroFields af = stamper.getAcroFields();
for (String sigName : af.getSignatureNames()) {
//v.addVerification(sigName, ocspClient, new
CrlClientOnline(chain), LtvVerification.CertificateOption.WHOLE_CHAIN,
LtvVerification.Level.OCSP_CRL, LtvVerification.CertificateInclusion.NO);
//v.addVerification(sigName, ocspClient, crlList.get(0),
LtvVerification.CertificateOption.SIGNING_CERTIFICATE,
LtvVerification.Level.OCSP_CRL, LtvVerification.CertificateInclusion.NO);
//v.addVerification(sigName, ocspClient, crlList.get(0),
LtvVerification.CertificateOption.SIGNING_CERTIFICATE,
LtvVerification.Level.CRL, LtvVerification.CertificateInclusion.NO);
v.addVerification(
sigName,
ocspClient,
new CrlClientOnline(chain),
LtvVerification.CertificateOption.WHOLE_CHAIN,
LtvVerification.Level.OCSP,
LtvVerification.CertificateInclusion.YES);
}
v.merge();
