/**
 *  @file
 *    This file contains class definition of an example operational certificate
 *    issuer for CHIP devices. The class can be used as a guideline on how to
 *    construct your own certificate issuer. It can also be used in tests and tools
 *    if a specific signing authority is not required.
 *
 *    NOTE: This class stores the encryption key in clear storage. This is not suited
 *          for production use. This should only be used in test tools.
