Method Detail

getInstance

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

getInstance
