Huks如何导入AES的密钥？

struct OH_Huks_Param GenerateKeyParam[] = { 
 
  {.tag = OH_HUKS_TAG_ALGORITHM, .uint32Param = OH_HUKS_ALG_AES}, 
 
{.tag = OH_HUKS_TAG_KEY_SIZE, .uint32Param = OH_HUKS_AES_KEY_SIZE_256}, 
 
{.tag = OH_HUKS_TAG_PURPOSE, .uint32Param = OH_HUKS_KEY_PURPOSE_ENCRYPT | OH_HUKS_KEY_PURPOSE_DECRYPT}, 
 
{.tag = OH_HUKS_TAG_PADDING, .uint32Param = OH_HUKS_PADDING_PKCS7} 
 
}; 
 
//导入方法： 
 
static napi_value importKeyPair(napi_env env, napi_callback_info info) { 
  /密钥数据 keyPair/ 
  unsigned char bbb[] = {103, 85, 233, 109, 228, 13, 36, 88, 9, 60, 23, 156, 0, 181, 243, 130, 
    141, 48, 183, 122, 89, 114, 73, 56, 32, 175, 60, 182, 70, 203, 69, 205}; 
  struct OH_Huks_Blob keyPair = {32, bbb}; 
/参数配置/ 
struct OH_Huks_ParamSet testImportKeyParamSet = nullptr; 
struct OH_Huks_Result ohResult; 
/初始化参数/ 
ohResult = InitParamSet(&testImportKeyParamSet, GenerateKeyParam, 
sizeof(GenerateKeyParam) / sizeof(OH_Huks_Param)); 
if (ohResult.errorCode != OH_HUKS_SUCCESS) { 
  return nullptr; 
} 
/ 4. Import Key */ 
char newKey[] = 'test_import'; 
struct OH_Huks_Blob newKeyAlias = {.size = (uint32_t)strlen(newKey), .data = (uint8_t )newKey}; 
ohResult = OH_Huks_ImportKeyItem(&newKeyAlias, testImportKeyParamSet, &keyPair); 
 
//检验是否存在（可不要） 
 
 
ohResult = OH_Huks_IsKeyItemExist(&newKeyAlias, testImportKeyParamSet); 
if (ohResult.errorCode != OH_HUKS_SUCCESS) { 
  return nullptr; 
}
