/*
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 need to
5
* rely on other algorithms, i.e. are 'composite' 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.
