/*
 *  Context structure declaration of the Mbed TLS software-based PSA drivers
 *  called through the PSA Crypto driver dispatch layer.
 *  This file contains the context structures of those algorithms which do not
 *  rely on other algorithms, i.e. are 'primitive' algorithms.
 *
 * \note This file may not be included directly. Applications must
 * include psa/crypto.h.
 *
 * \note This header and its content is not part of the Mbed TLS API and
 * applications must not depend on it. Its main purpose is to define the
 * multi-part state objects of the Mbed TLS software-based PSA drivers. The
 * definition of these objects are then used by crypto_struct.h to define the
 * implementation-defined types of PSA multi-part state objects.
