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 21 * 22 * Licensed under the Apache License, Version 2.0 (the "License"); you may 23 * not use this file except in compliance with the License. 24 * You may obtain a copy of the License at 25 * 26 * http://www.apache.org/licenses/LICENSE-2.0 27 * 28 * Unless required by applicable law or agreed to in writing, software 29 * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT 30 * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 31 * See the License for the specific language governing permissions and 32 * limitations under the License. 33 */ 34 #ifndef PSA_CRYPTO_DRIVER_COMMON_H 35 #define PSA_CRYPTO_DRIVER_COMMON_H 36 37 #include <stddef.h> 38 #include <stdint.h> 39 40 /* Include type definitions (psa_status_t, psa_algorithm_t, 41 * psa_key_type_t, etc.) and macros to build and analyze values 42 * of these types. */ 43 #include "crypto_types.h" 44 #include "crypto_values.h" 45 /* Include size definitions which are used to size some arrays in operation 46 * structures. */ 47 #include <psa/crypto_sizes.h> 48 49 /** For encrypt-decrypt functions, whether the operation is an encryption 50 * or a decryption. */ 51 typedef enum { 52 PSA_CRYPTO_DRIVER_DECRYPT, 53 PSA_CRYPTO_DRIVER_ENCRYPT 54 } psa_encrypt_or_decrypt_t; 55 56 #endif /* PSA_CRYPTO_DRIVER_COMMON_H */ 57
