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 psa_algorithm_t MBEDTLS_PRIVATE(alg); 61 union { 62 unsigned dummy; /* Make the union non-empty even with no supported algorithms. */ 63 #if defined(MBEDTLS_PSA_BUILTIN_ALG_MD5) 64 mbedtls_md5_context md5; 65 #endif 66 #if defined(MBEDTLS_PSA_BUILTIN_ALG_RIPEMD160) 67 mbedtls_ripemd160_context ripemd160; 68 #endif 69 #if defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_1) 70 mbedtls_sha1_context sha1; 71 #endif 72 #if defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_256) || \ 73 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_224) 74 mbedtls_sha256_context sha256; 75 #endif 76 #if defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_512) || \ 77 defined(MBEDTLS_PSA_BUILTIN_ALG_SHA_384) 78 mbedtls_sha512_context 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_ECB_NO_PADDING) || \ 96 defined(MBEDTLS_PSA_BUILTIN_ALG_CBC_NO_PADDING) || \ 97 defined(MBEDTLS_PSA_BUILTIN_ALG_CBC_PKCS7) 98 #define MBEDTLS_PSA_BUILTIN_CIPHER 1 99 #endif 100 101 typedef struct { 102 /* Context structure for the Mbed TLS cipher implementation. */ 103 psa_algorithm_t MBEDTLS_PRIVATE(alg); 104 uint8_t MBEDTLS_PRIVATE(iv_length); 105 uint8_t MBEDTLS_PRIVATE(block_length); 106 union { 107 unsigned int MBEDTLS_PRIVATE(dummy); 108 mbedtls_cipher_context_t MBEDTLS_PRIVATE(cipher); 109 } MBEDTLS_PRIVATE(ctx); 110 } mbedtls_psa_cipher_operation_t; 111 112 #define MBEDTLS_PSA_CIPHER_OPERATION_INIT { 0, 0, 0, { 0 } } 113 114 #endif /* PSA_CRYPTO_BUILTIN_PRIMITIVES_H */ 115
