[参考译文] CC2745R10-Q1：关于 AESCBC_oneStepDecrypt

您好：

1) 是否有办法使用 CryptoKey_keystore 编码（使用 keystore _PSA_initKey 初始化密钥）来解密 AESCBC？
如果是、请告诉我如何操作。
未来的 SDK 版本是否支持 CryptoKey_keystore 编码？

2)3)

下面是使用 keystore PSA_initKeyHSM 函数进行 AESCBC 解密的测试代码。

static void vos_CBC_test( void )
{
    KeyStore_PSA_KeyFileId      stt_keyID;
    KeyStore_PSA_KeyAttributes  stt_attributes = KEYSTORE_PSA_KEY_ATTRIBUTES_INIT;
    AESCBC_Operation     stS_CryptIf_AESCBC_Operation;
    CryptoKey            stt_CryptoKey;
    AESCBC_Handle        psts_AesCbcHandle;
    int_fast16_t s2s_status;

    uint8_t au1s_Key[16] = {0x06, 0xa9, 0x21, 0x40, 0x36, 0xb8, 0xa1, 0x5b, 0x51, 0x2e, 0x03, 0xd5, 0x34, 0x12, 0x00, 0x06};
    uint8_t au1s_iv[16] =  {0x2f, 0xe2, 0xb3, 0x33, 0xce, 0xda, 0x8f, 0x98, 0xf4, 0xa9, 0x9b, 0x40, 0xd2, 0xcd, 0x34, 0xa8};
    uint8_t au1s_In[16] =  {0x47, 0x48, 0x7F, 0xAC, 0x8f, 0xa4, 0xfa, 0x72, 0x9B, 0xB7, 0xC6, 0x62, 0x36, 0x1a, 0x51, 0x94};
    uint8_t au1s_Out[16] = {0};    
    
    s2s_status = KeyStore_PSA_init();
    if (s2s_status != KEYSTORE_PSA_STATUS_SUCCESS)
    {
        while(1);
    }

    s2s_status = HSMLPF3_provisionHUK();
    if (s2s_status != HSMLPF3_STATUS_SUCCESS)
    {
        while(1);
    }

    KeyStore_PSA_setKeyLifetime(&stt_attributes, KEYSTORE_PSA_KEY_LIFETIME_FROM_PERSISTENCE_AND_LOCATION(KEYSTORE_PSA_KEY_PERSISTENCE_DEFAULT, KEYSTORE_PSA_KEY_LOCATION_HSM_ASSET_STORE));
    KeyStore_PSA_setKeyBits(&stt_attributes, 128);
    /* Import the keyingMaterial */
    s2s_status = KeyStore_PSA_importKey(&stt_attributes, au1s_Key, (size_t)16, &stt_keyID);
    
    AESCBC_init();
    s2s_status = KeyStore_PSA_initKeyHSM( &stt_CryptoKey, stt_keyID, (size_t)16, NULL );
    if (s2s_status != KEYSTORE_PSA_STATUS_SUCCESS)
    {
        while(1);
    }

    psts_AesCbcHandle = AESCBC_open(0, NULL);
    
    AESCBC_OneStepOperation_init( &stS_CryptIf_AESCBC_Operation );
    stS_CryptIf_AESCBC_Operation.key               = &stt_CryptoKey;
    stS_CryptIf_AESCBC_Operation.input             = (uint8_t*)au1s_In;
    stS_CryptIf_AESCBC_Operation.output            = (uint8_t*)au1s_Out;
    stS_CryptIf_AESCBC_Operation.inputLength       = sizeof(au1s_Out);
    stS_CryptIf_AESCBC_Operation.iv                = (uint8_t*)au1s_iv;
        
    s2s_status = AESCBC_oneStepDecrypt( psts_AesCbcHandle, &stS_CryptIf_AESCBC_Operation );
    
    AESCBC_close(psts_AesCbcHandle);
    
    if(s2s_status != AESCBC_STATUS_SUCCESS)
    {
        while(1);
    }
}

当我调试它时、我发现 ENABLE_KEY_STORAGE 被禁用、因此显示错误消息 AESCBC_STATUS_FEATURE_NOT_SUPPORTED、代码被终止。
请告诉我如何解决此问题。

SysConfig 设置如下：
