/*

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