- - ### Constructor Detail

    - #### DigestedData

          public DigestedData​(AlgorithmIdentifier digestAlgorithm,
                              ContentInfo encapContentInfo,
                              byte[] digest)

  - ### Method Detail

    - #### getInstance

          public static DigestedData getInstance​(ASN1TaggedObject ato,
                                                 boolean isExplicit)

      Return a DigestedData object from a tagged object.
      Parameters:
        `ato` - the tagged object holding the object we want.
        `isExplicit` - true if the object is meant to be explicitly tagged false otherwise.
      Throws:
        `java.lang.IllegalArgumentException` - if the object held by the tagged object cannot be converted.

    - #### getInstance

          public static DigestedData getInstance​(java.lang.Object obj)

      Return a DigestedData object from the given object.

      Accepted inputs:

      - null → null
      - `DigestedData` object
      - `ASN1Sequence` input formats
      Parameters:
        `obj` - the object we want converted.
      Throws:
        `java.lang.IllegalArgumentException` - if the object cannot be converted.

    - #### getVersion

          public ASN1Integer getVersion()

    - #### getDigestAlgorithm

          public AlgorithmIdentifier getDigestAlgorithm()

    - #### getEncapContentInfo

          public ContentInfo getEncapContentInfo()

    - #### toASN1Primitive

          public ASN1Primitive toASN1Primitive()

      Description copied from class: `ASN1Object`
      Method providing a primitive representation of this object suitable for encoding.
      Specified by:
        `toASN1Primitive` in interface `ASN1Encodable`
      Specified by:
        `toASN1Primitive` in class `ASN1Object`
      Returns:
        a primitive representation of this object.

    - #### getDigest
