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. - * - * <h3>Design notes about multipart operation structures</h3> - * - * For multipart operations without driver delegation support, each multipart - * operation structure contains a `psa_algorithm_t alg` field which indicates - * which specific algorithm the structure is for. When the structure is not in - * use, `alg` is 0. Most of the structure consists of a union which is - * discriminated by `alg`. - * - * For multipart operations with driver delegation support, each multipart - * operation structure contains an `unsigned int id` field indicating which - * driver got assigned to do the operation. When the structure is not in use, - * 'id' is 0. The structure contains also a driver context which is the union - * of the contexts of all drivers able to handle the type of multipart - * operation. - * - * Note that when `alg` or `id` is 0, the content of other fields is undefined. - * In particular, it is not guaranteed that a freshly-initialized structure - * is all-zero: we initialize structures to something like `{0, 0}`, which - * is only guaranteed to initializes the first member of the union; - * GCC and Clang initialize the whole structure to 0 (at the time of writing), - * but MSVC and CompCert don't. - * - * In Mbed Crypto, multipart operation structures live independently from - * the key. This allows Mbed Crypto to free the key objects when destroying - * a key slot. If a multipart operation needs to remember the key after - * the setup function returns, the operation structure needs to contain a - * copy of the key. - */ -/* - * Copyright The Mbed TLS Contributors - * SPDX-License-Identifier: Apache-2.0 - * - * Licensed under the Apache License, Version 2.0 (the "License"); you may - * not use this file except in compliance with the License. - * You may obtain a copy of the License at - * - * http://www.apache.org/licenses/LICENSE-2.0 - * - * Unless required by applicable law or agreed to in writing, software - * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT - * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - * See the License for the specific language governing permissions and - * limitations under the License. - */ - -#ifndef PSA_CRYPTO_STRUCT_H -#define PSA_CRYPTO_STRUCT_H - -#ifdef __cplusplus -extern "C" { -#endif - -/* Include the Mbed TLS configuration file, the way Mbed TLS does it - * in each of its header files. */ -#if !defined(MBEDTLS_CONFIG_FILE) -#include "mbedtls/config.h" -#else -#include MBEDTLS_CONFIG_FILE -#endif - -#include "mbedtls/cmac.h" -#include "mbedtls/gcm.h" - -/* Include the context definition for the compiled-in drivers for the primitive - * algorithms. */ -#include "psa/crypto_driver_contexts_primitives.h" - -struct psa_hash_operation_s -{ - /** Unique ID indicating which driver got assigned to do the - * operation.
