( 'The PDF has been successfully cryptographically signed with long-term validation.') SignPdf(json, 'qa_output/hello_ltv_signed.pdf') Tell the pdf object to use the certificate for signing. LoadPfxFile( 'qa_data/pfx/myPdfSigningCert.pfx', 'pfxPassword') (Use your own certificate.) CkCert cert = new CkCert() UpdateString( 'appearance.text', 'This is an LTV-enabled signature.') UpdateString( 'appearance.text', 'current_dt')

UpdateString( 'appearance.text', 'Digitally signed by: cert_cn') UpdateString( 'appearance.fontScale', '10.0') Define the appearance of the signature. Therefore, Chilkat will send an OCSP request to the signing certificate's OCSP URl (if one exists) // and will download the CRL from the issuer certificate's CRL Distribution Point (if one exists). The pdfRevocationInfoArchival attribute (1.2.840.113583.1.1.8) // contains OCSP responses and the CRL for the issuer of the signing certificate. // Also, the 'ltvOcsp' causes Chilkat to add the pdfRevocationInfoArchival authenticated attribute // to the CMS signature. Also, and certificates from existing signatures not yet in the DSS are added to the /Certs // in the DSS. Chilkat will add the OCSP responses to the /OCSPs in the Document Security Store (/DSS). // If we are signing a PDF that already has signatures, then the existing signatures // are automatically verified, and Chilkat will do OCSP certificate status checking (if possible) // for those certs in existing signatures (including certs in the certificate chains) // that do not yet have a valid OCSP response in the DSS (Document Security Store). This is what causes Chilkat to create an LTV-enabled signature.

Add the 'ltvOcsp' instruction to the JSON passed to SignPdf. In this article, I will introduce how to use a free Java API to add a digital signature to an existing PDF document. In most cases, the signingCertificateV2 and signingTime attributes are required. Java Digital Signature API, Add eSignature to PDF Word Excel Image Products / GroupDocs.Signature / Java Java API to Manage Digital Signatures Manage eSignature of Image, QR-Code, Barcode, Metadata, Text & Stamp Types in Java Applications for Signing Images & Digital Document File Formats. Options for signing are specified in JSON. The 'hello.pdf' is available at boolean success = pdf. See Global Unlock Sample for sample code.

This example requires the Chilkat API to have been previously unlocked.
