    - #### getInstance

          public static RecipientInfo getInstance(java.lang.Object o)

      Return a RecipientInfo object from the given object.

      Accepted inputs:

      - null → null
      - `RecipientInfo` object
      - `ASN1Sequence` input formats with RecipientInfo structure inside
      - `ASN1TaggedObject` input formats with RecipientInfo structure inside
      Parameters:
        `o` - the object we want converted.
      Throws:
        `java.lang.IllegalArgumentException` - if the object cannot be converted.

    - #### getVersion

    - #### isTagged

          public boolean isTagged()

    - #### getInfo

          public ASN1Encodable getInfo()

    - #### 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.
