    - #### EncryptedData

          public EncryptedData(EncryptedContentInfo encInfo,
                               ASN1Set unprotectedAttrs)

  - ### Method Detail

    - #### getInstance

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

      Return an EncryptedData object from the given object.

      Accepted inputs:

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