/**
 * \file psa/crypto_struct.h
 *
 * \brief PSA cryptography module: structured type implementations
 *
 * This file contains a list of structures that each implementation
 * of the PSA Crypto API must define, as well as sample definitions
 * for initializers.
 *
 * \note This file may not be included directly. Applications must
 * include psa/crypto.h.
 *
 * This file contains the definitions of some data structures with
 * implementation-specific definitions.
 *
 * In implementations with isolation between the application and the
 * cryptography module, it is expected that the front-end and the back-end
 * would have different versions of this file.
