## Overview
Defines the capabilities of OpenHarmony Universal KeyStore (HUKS) parameter sets. The HUKS APIs can be used to perform parameter set lifecycle management, including initializing a parameter set, adding parameters to a parameter set, constructing a parameter set, and destroying a parameter set. They can also be used to obtain parameters, copy parameter sets, and check parameter validity.
Defines HUKS parameter set management capabilities, including HUKS parameter set lifecycle management such as initializing a parameter set, adding parameters, building a parameter set, and freeing a parameter set, as well as functions such as obtaining parameters, copying a parameter set, querying a parameter set, and checking the validity of a parameter set.
