2  *  Context structure declaration of the Mbed TLS software-based PSA drivers
3  *  called through the PSA Crypto driver dispatch layer.
4  *  This file contains the context structures of those algorithms which do not
5  *  rely on other algorithms, i.e. are 'primitive' algorithms.
6  *
7  * \note This file may not be included directly. Applications must
8  * include psa/crypto.h.
9  *
10  * \note This header and its content is not part of the Mbed TLS API and
11  * applications must not depend on it. Its main purpose is to define the
12  * multi-part state objects of the Mbed TLS software-based PSA drivers. The
13  * definition of these objects are then used by crypto_struct.h to define the
14  * implementation-defined types of PSA multi-part state objects.
