Interface EmbeddedEvidenceRecordHelper

All Known Implementing Classes:
AbstractEmbeddedEvidenceRecordHelper, CAdESEmbeddedEvidenceRecordHelper, XAdESEmbeddedEvidenceRecordHelper
public interface EmbeddedEvidenceRecordHelper
This class contains utility methods required for a processing and validation of an embedded evidence record

  • Method Details

    • getMasterSignature

      AdvancedSignature getMasterSignature()
      Gets a master signature, enveloping the current evidence record
      Returns:
      AdvancedSignature

    • getEvidenceRecordAttribute

      SignatureAttribute getEvidenceRecordAttribute()
      Gets the unsigned attribute property embedding the evidence record. NOTE: can be null in case of a not yet embedded evidence record.
      Returns:
      SignatureAttribute

    • getOrderOfAttribute

      Integer getOrderOfAttribute()
      Gets position of the evidence record carrying attribute within the signature NOTE: can be null in case of a not yet embedded evidence record.
      Returns:
      Integer

    • getOrderWithinAttribute

      Integer getOrderWithinAttribute()
      Gets position of the evidence record within its carrying attribute NOTE: can be null in case of a not yet embedded evidence record.
      Returns:
      Integer

    • getDetachedContents

      List<DSSDocument> getDetachedContents()
      Gets a list of detached documents
      Returns:
      a list of DSSDocuments

    • getMasterSignatureDigest

      Digest getMasterSignatureDigest(DigestAlgorithm digestAlgorithm)
      Builds digest for the embedded evidence record for the given DigestAlgorithm. This method uses an existing coding of a signature for hash generation.
      Parameters:
      digestAlgorithm - DigestAlgorithm
      Returns:
      Digest

    • getMasterSignatureDigest

      Digest getMasterSignatureDigest(DigestAlgorithm digestAlgorithm, boolean derEncoded)
      Builds digest for the embedded evidence record for the given DigestAlgorithm using a specified encoding. The method can be called only for a CAdES signature implementation. NOTE: please use the method #isEncodingSelectionSupported to check whether the encoding choice is supported by the current implementation. Use #getMasterSignatureDigest(digestAlgorithm) method otherwise.
      Parameters:
      digestAlgorithm - DigestAlgorithm
      derEncoded - whether the signature shall be DER-encoded
      Returns:
      Digest

    • isEncodingSelectionSupported

      boolean isEncodingSelectionSupported()
      Gets whether the selection of a target encoding is supported by the current implementation. This method is used to resolve the interoperability issues between ETSI TS 119 122-3 and RFC 4998 embedded ERS, requiring hash computation in different ways.
      Returns:
      TRUE if the encoding selection is supported by the current implementation, FALSE otherwise
