## cl.security.1 Deprecation of getSdkVersion and enum HUKS_AES_KEY_SIZE_512

Public

**Reason for Change**

The **getSdkVersion** API and **enum HUKS_AES_KEY_SIZE_512** are reserved interfaces without any functionality.  These interfaces are redundant and therefore deprecated.

**Change Impact**

The change is not compatible with earlier versions. Use the new API in your code.

**API Level**

**Deprecated Since**
