/*
 * This structure is used to set the cyrpto callback function for station to connect when in security mode.
 * These functions either call MbedTLS API's if USE_MBEDTLS_CRYPTO flag is set through Kconfig, or native
 * API's otherwise. We recommend setting the flag since MbedTLS API's utilize hardware acceleration while
 * native API's are use software implementations.
