/** * \file psa/crypto_driver_common.h * \brief Definitions for all PSA crypto drivers * * This file contains common definitions shared by all PSA crypto drivers. * Do not include it directly: instead, include the header file(s) for * the type(s) of driver that you are implementing. For example, if * you are writing a driver for a chip that provides both a hardware * random generator and an accelerator for some cryptographic algorithms, * include `psa/crypto_entropy_driver.h` and `psa/crypto_accel_driver.h`. * * This file is part of the PSA Crypto Driver Model, containing functions for * driver developers to implement to enable hardware to be called in a * standardized way by a PSA Cryptographic API implementation. The functions * comprising the driver model, which driver authors implement, are not * intended to be called by application developers. */ /* * 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_DRIVER_COMMON_H #define PSA_CRYPTO_DRIVER_COMMON_H #include #include /* Include type definitions (psa_status_t, psa_algorithm_t, * psa_key_type_t, etc.) and macros to build and analyze values * of these types. */ #include "crypto_types.h" #include "crypto_values.h" /** For encrypt-decrypt functions, whether the operation is an encryption * or a decryption. */ typedef enum { PSA_CRYPTO_DRIVER_DECRYPT, PSA_CRYPTO_DRIVER_ENCRYPT } psa_encrypt_or_decrypt_t; #endif /* PSA_CRYPTO_DRIVER_COMMON_H */
