  • Method Details

    • getInstance

      public static AuthenticatedData getInstance(org.bouncycastle.asn1.ASN1TaggedObject obj, boolean explicit)
      Return an AuthenticatedData 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.
      Returns:
      a reference that can be assigned to AuthenticatedData (may be null)
      Throws:
      IllegalArgumentException - if the object held by the tagged object cannot be converted.

    • getInstance

      public static AuthenticatedData getInstance(Object obj)
      Return an AuthenticatedData object from the given object.

      Accepted inputs:

      • null → null
      • AuthenticatedData object
      • ASN1Sequence input formats with AuthenticatedData structure inside
      Parameters:
      obj - the object we want converted.
      Returns:
      a reference that can be assigned to AuthenticatedData (may be null)
      Throws:
      IllegalArgumentException - if the object cannot be converted.
