    - #### AuthEnvelopedData

          public AuthEnvelopedData(OriginatorInfo originatorInfo,
                                   ASN1Set recipientInfos,
                                   EncryptedContentInfo authEncryptedContentInfo,
                                   ASN1Set authAttrs,
                                   ASN1OctetString mac,
                                   ASN1Set unauthAttrs)

  - ### Method Detail

    - #### getInstance

          public static AuthEnvelopedData getInstance(ASN1TaggedObject obj,
                                                      boolean explicit)

      Return an AuthEnvelopedData object from a tagged object.

      Accepted inputs:

      - `ASN1Sequence` input formats
      Parameters:
        `obj` - the tagged object holding the object we want.
        `explicit` - true if the object is meant to be explicitly tagged false otherwise.
      Returns:
        a reference that can be assigned to AuthEnvelopedData (may be null)
      Throws:
        `java.lang.IllegalArgumentException` - if the object held by the tagged object cannot be converted.

    - #### getInstance

          public static AuthEnvelopedData getInstance(java.lang.Object obj)

      Return an AuthEnvelopedData object from the given object.

      Accepted inputs:

      - null → null
      - `AuthEnvelopedData` object
      - `org.bouncycastle.asn1.ASN1Sequence` input formats with AuthEnvelopedData structure inside
      Parameters:
        `obj` - The object we want converted.
      Returns:
        a reference that can be assigned to AuthEnvelopedData (may be null)
      Throws:
        `java.lang.IllegalArgumentException` - if the object cannot be converted, or was null.
