Method Detail

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:
java.lang.IllegalArgumentException
- if the object held by the tagged object cannot be converted.
-
getInstance
public static AuthenticatedData getInstance(java.lang.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:
java.lang.IllegalArgumentException
- if the object cannot be converted.
