    Constructor Description
    CadesLevelBaselineLTATimestampExtractor​(CAdESSignature cadesSignature)
    This is the default constructor for the CadesLevelBaselineLTATimestampExtractor.
    CadesLevelBaselineLTATimestampExtractor​(org.bouncycastle.cms.CMSSignedData cmsSignedData, Collection<eu.europa.esig.dss.model.x509.CertificateToken> signatureCertificates, Collection<eu.europa.esig.dss.model.x509.CertificateToken> timestampCertificates)  

  • Method Summary

    Modifier and Type Method Description
    byte[] getArchiveTimestampDataV3​(org.bouncycastle.cms.SignerInformation signerInformation, org.bouncycastle.asn1.cms.Attribute atsHashIndexAttribute, byte[] originalDocumentDigest)  
    org.bouncycastle.asn1.cms.Attribute getAtsHashIndex​(org.bouncycastle.cms.SignerInformation signerInformation, eu.europa.esig.dss.enumerations.DigestAlgorithm hashIndexDigestAlgorithm)
    The ats-hash-index unsigned attribute provides an unambiguous imprint of the essential components of a CAdES signature for use in the archive time-stamp (see 6.4.3).
    org.bouncycastle.asn1.cms.Attribute getVerifiedAtsHashIndex​(org.bouncycastle.cms.SignerInformation signerInformation, TimestampToken timestampToken)
    get the atsHash index for verification of the provided token.

    • getAtsHashIndex

      public org.bouncycastle.asn1.cms.Attribute getAtsHashIndex​(org.bouncycastle.cms.SignerInformation signerInformation, eu.europa.esig.dss.enumerations.DigestAlgorithm hashIndexDigestAlgorithm)
      The ats-hash-index unsigned attribute provides an unambiguous imprint of the essential components of a CAdES signature for use in the archive time-stamp (see 6.4.3). These essential components are elements of the following ASN.1 SET OF structures: unsignedAttrs, SignedData.certificates, and SignedData.crls. The ats-hash-index attribute value has the ASN.1 syntax ATSHashIndex: ATSHashIndex ::= SEQUENCE { hashIndAlgorithm AlgorithmIdentifier DEFAULT {algorithm id-sha256}, certificatesHashIndex SEQUENCE OF OCTET STRING, crlsHashIndex SEQUENCE OF OCTET STRING,
      Parameters:
      signerInformation -
      Returns:

    • getVerifiedAtsHashIndex

      public org.bouncycastle.asn1.cms.Attribute getVerifiedAtsHashIndex​(org.bouncycastle.cms.SignerInformation signerInformation, TimestampToken timestampToken)
      get the atsHash index for verification of the provided token.
      Parameters:
      signerInformation -
      timestampToken -
      Returns:
