All Implemented Interfaces:

TPMU_PUBLIC_PARMS, TpmMarshaller, TpmUnion

public class TPMS_ASYM_PARMS
extends TpmStructure
implements TPMU_PUBLIC_PARMS

This structure contains the common public area parameters for an asymmetric key. The first two parameters of the parameter definition structures of an asymmetric key shall have the same two first components.
