1 /* 2 * Context structure declaration of the Mbed TLS software-based PSA drivers 3 * called through the PSA Crypto driver dispatch layer. 4 * This file contains the context structures of those algorithms which do not 5 * rely on other algorithms, i.e. are 'primitive' algorithms. 6 * 7 * \note This file may not be included directly. Applications must 8 * include psa/crypto.h. 9 * 10 * \note This header and its content is not part of the Mbed TLS API and 11 * applications must not depend on it. Its main purpose is to define the 12 * multi-part state objects of the Mbed TLS software-based PSA drivers. The 13 * definition of these objects are then used by crypto_struct.h to define the 14 * implementation-defined types of PSA multi-part state objects. 15 */ 16 /* 17 * Copyright The Mbed TLS Contributors 18 * SPDX-License-Identifier: Apache-2.0 19 * 20 * Licensed under the Apache License, Version 2.0 (the "License"); you may 21 * not use this file except in compliance with the License. 22 * You may obtain a copy of the License at 23 * 24 * http://www.apache.org/licenses/LICENSE-2.0 25 * 26 * Unless required by applicable law or agreed to in writing, software 27 * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT 28 * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 29 * See the License for the specific language governing permissions and 30 * limitations under the License. 31 */ 32 33 #ifndef PSA_CRYPTO_BUILTIN_PRIMITIVES_H 34 #define PSA_CRYPTO_BUILTIN_PRIMITIVES_H 35 #include "mbedtls/private_access.h" 36 37 #include <psa/crypto_driver_common.h> 38 39 /* 40 * Hash multi-part operation definitions. 41 */ 42 43 #include "mbedtls/md5.h" 44 #include "mbedtls/ripemd160.h" 45 #include "mbedtls/sha1.h" 46 #include "mbedtls/sha256.h" 47 #include "mbedtls/sha512.h" 48 49 #if defined(MBEDTLS_PSA_BUILTIN_ALG_MD5) || \ 50 defined(MBEDTLS_PSA_BUILTIN_ALG_RIPEMD160) || \ 51 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_1) || \ 52 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_224) || \ 53 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_256) || \ 54 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_384) || \ 55 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_512) 56 #define MBEDTLS_PSA_BUILTIN_HASH 57 #endif 58 59 typedef struct 60 { 61 psa_algorithm_t MBEDTLS_PRIVATE(alg); 62 union 63 { 64 unsigned MBEDTLS_PRIVATE(dummy); /* Make the union non-empty even with no supported algorithms. */ 65 #if defined(MBEDTLS_MD5_C) 66 mbedtls_md5_context MBEDTLS_PRIVATE(md5); 67 #endif 68 #if defined(MBEDTLS_RIPEMD160_C) 69 mbedtls_ripemd160_context MBEDTLS_PRIVATE(ripemd160); 70 #endif 71 #if defined(MBEDTLS_SHA1_C) 72 mbedtls_sha1_context MBEDTLS_PRIVATE(sha1); 73 #endif 74 #if defined(MBEDTLS_SHA256_C) 75 mbedtls_sha256_context MBEDTLS_PRIVATE(sha256); 76 #endif 77 #if defined(MBEDTLS_SHA512_C) 78 mbedtls_sha512_context MBEDTLS_PRIVATE(sha512); 79 #endif 80 } MBEDTLS_PRIVATE(ctx); 81 } mbedtls_psa_hash_operation_t; 82 83 #define MBEDTLS_PSA_HASH_OPERATION_INIT {0, {0}} 84 85 /* 86 * Cipher multi-part operation definitions. 87 */ 88 89 #include "mbedtls/cipher.h" 90 91 #if defined(MBEDTLS_PSA_BUILTIN_ALG_STREAM_CIPHER) || \ 92 defined(MBEDTLS_PSA_BUILTIN_ALG_CTR) || \ 93 defined(MBEDTLS_PSA_BUILTIN_ALG_CFB) || \ 94 defined(MBEDTLS_PSA_BUILTIN_ALG_OFB) || \ 95 defined(MBEDTLS_PSA_BUILTIN_ALG_XTS) || \ 96 defined(MBEDTLS_PSA_BUILTIN_ALG_ECB_NO_PADDING) || \ 97 defined(MBEDTLS_PSA_BUILTIN_ALG_CBC_NO_PADDING) || \ 98 defined(MBEDTLS_PSA_BUILTIN_ALG_CBC_PKCS7) 99 #define MBEDTLS_PSA_BUILTIN_CIPHER 1 100 #endif 101 102 typedef struct { 103 /* Context structure for the Mbed TLS cipher implementation. */ 104 psa_algorithm_t MBEDTLS_PRIVATE(alg); 105 uint8_t MBEDTLS_PRIVATE(iv_length); 106 uint8_t MBEDTLS_PRIVATE(block_length); 107 union { 108 unsigned int MBEDTLS_PRIVATE(dummy); 109 mbedtls_cipher_context_t MBEDTLS_PRIVATE(cipher); 110 } MBEDTLS_PRIVATE(ctx); 111 } mbedtls_psa_cipher_operation_t; 112 113 #define MBEDTLS_PSA_CIPHER_OPERATION_INIT {0, 0, 0, {0}} 114 115 /* 116 * BEYOND THIS POINT, TEST DRIVER DECLARATIONS ONLY. 117 */ 118 #if defined(PSA_CRYPTO_DRIVER_TEST) 119 120 typedef mbedtls_psa_hash_operation_t mbedtls_transparent_test_driver_hash_operation_t; 121 122 #define MBEDTLS_TRANSPARENT_TEST_DRIVER_HASH_OPERATION_INIT MBEDTLS_PSA_HASH_OPERATION_INIT 123 124 typedef mbedtls_psa_cipher_operation_t 125 mbedtls_transparent_test_driver_cipher_operation_t; 126 127 typedef struct { 128 unsigned int initialised : 1; 129 mbedtls_transparent_test_driver_cipher_operation_t ctx; 130 } mbedtls_opaque_test_driver_cipher_operation_t; 131 132 #define MBEDTLS_TRANSPARENT_TEST_DRIVER_CIPHER_OPERATION_INIT \ 133 MBEDTLS_PSA_CIPHER_OPERATION_INIT 134 135 #define MBEDTLS_OPAQUE_TEST_DRIVER_CIPHER_OPERATION_INIT \ 136 { 0, MBEDTLS_TRANSPARENT_TEST_DRIVER_CIPHER_OPERATION_INIT } 137 138 #endif /* PSA_CRYPTO_DRIVER_TEST */ 139 140 #endif /* PSA_CRYPTO_BUILTIN_PRIMITIVES_H */ 141
