       Tspi_ChangeAuthAsym  -  change the authorization data of an entity using asymmetric change
       protocol.

SYNOPSIS

       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.h>

       TSS_RESULT Tspi_ChangeAuthAsym(TSS_HOBJECT hObjectToChange, TSS_HOBJECT hParentObject,
                                      TSS_HKEY    hIdentKey,       TSS_HPOLICY hNewPolicy);

DESCRIPTION

       Tspi_ChangeAuthAsym  changes  the  authorization  data  (secret)  of  an  entity  (object)
       utilizing  the asymmetric change protocol and assigns the object to the policy object. All
       classes using secrets provide this method for changing  their  authorization  data.   This
       method  changes the authorization data of an object ensuring that the parent of the object
       does not get knowledge of the new secret.

PARAMETERS

   hObjectToChange
       Handle of the object the authorization data should be changed.

   hParentObject
       Handle of the parent object wrapping the object addressed by hObjectToChange.

   hIdentKey
       Handle of the identity key object required to proof the internally created temporary key.

   hNewPolicy
       Handle of the policy object providing the new authorization data.

RETURN CODES

       Tspi_ChangeAuthAsym returns TSS_SUCCESS on success, otherwise one of the following  values
       are returned:

       TSS_E_INVALID_HANDLE  -  Either hObjectToChange, hParentObject, or hIdentKey is an invalid
       handle.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

       Tspi_ChangeAuthAsym conforms to the Trusted Computing Group Software Specification version
