    - #### KEKIdentifier

          public KEKIdentifier(byte[] keyIdentifier,
                               ASN1GeneralizedTime date,
                               OtherKeyAttribute other)

  - ### Method Detail

    - #### getInstance

          public static KEKIdentifier getInstance(ASN1TaggedObject obj,
                                                  boolean explicit)

      Return a KEKIdentifier object from a tagged object.
      Parameters:
        `obj` - the tagged object holding the object we want.
        `explicit` - 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 KEKIdentifier getInstance(java.lang.Object obj)

      Return a KEKIdentifier object from the given object.

      Accepted inputs:

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

    - #### getKeyIdentifier

          public ASN1OctetString getKeyIdentifier()

    - #### getDate

          public ASN1GeneralizedTime getDate()

    - #### getOther

          public OtherKeyAttribute getOther()

    - #### toASN1Primitive

          public ASN1Primitive toASN1Primitive()

      Produce an object suitable for an ASN1OutputStream.
      Specified by:
        `toASN1Primitive` in interface `ASN1Encodable`
      Specified by:
        `toASN1Primitive` in class `ASN1Object`
      Returns:
        a primitive representation of this object.
