1 /** 2 * \file psa/crypto_driver_common.h 3 * \brief Definitions for all PSA crypto drivers 4 * 5 * This file contains common definitions shared by all PSA crypto drivers. 6 * Do not include it directly: instead, include the header file(s) for 7 * the type(s) of driver that you are implementing. For example, if 8 * you are writing a dynamically registered driver for a secure element, 9 * include `psa/crypto_se_driver.h`. 10 * 11 * This file is part of the PSA Crypto Driver Model, containing functions for 12 * driver developers to implement to enable hardware to be called in a 13 * standardized way by a PSA Cryptographic API implementation. The functions 14 * comprising the driver model, which driver authors implement, are not 15 * intended to be called by application developers. 16 */ 17 18 /* 19 * Copyright The Mbed TLS Contributors 20 * SPDX-License-Identifier: Apache-2.0 OR GPL-2.0-or-later 21 */ 22 #ifndef PSA_CRYPTO_DRIVER_COMMON_H 23 #define PSA_CRYPTO_DRIVER_COMMON_H 24 25 #include <stddef.h> 26 #include <stdint.h> 27 28 /* Include type definitions (psa_status_t, psa_algorithm_t, 29 * psa_key_type_t, etc.) and macros to build and analyze values 30 * of these types. */ 31 #include "crypto_types.h" 32 #include "crypto_values.h" 33 /* Include size definitions which are used to size some arrays in operation 34 * structures. */ 35 #include <psa/crypto_sizes.h> 36 37 /** For encrypt-decrypt functions, whether the operation is an encryption 38 * or a decryption. */ 39 typedef enum { 40 PSA_CRYPTO_DRIVER_DECRYPT, 41 PSA_CRYPTO_DRIVER_ENCRYPT 42 } psa_encrypt_or_decrypt_t; 43 44 #endif /* PSA_CRYPTO_DRIVER_COMMON_H */
