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

    • isAbsentHashtreeSupported

      boolean isAbsentHashtreeSupported()
      Gets whether the embedded evidence records without the reduced hashtree are supported by the current signature implementation. This method resolves the difference on processing between CAdES (TS 119 122-3) and XAdES (TS 119 132-3) embedded evidence records, with the CAdES allowing omitted reduced hashtree, while XAdES requiring such.
      Returns:
      whether the absent reduced hashtree is supported by the current implementation
