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

Tspi_ChangeAuthAsym conforms to the Trusted Computing Group Software Specification version 1.1 Golden

Tspi_ChangeAuthAsym  changes the authorization data (secret) of an entity (object) utilizing the asymmet‐
       ric  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.

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

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.

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.
