Deleting a Key (C/C++)
To ensure data security, delete the key that is no longer required.
How to Develop
For example, delete a 256-bit HKDF key.
-
Set the key alias (keyAlias), which cannot exceed 64 bytes. paramSet is a reserved parameter. Leave it empty.
-
Use OH_Huks_DeleteKeyItem to delete the key.
#include "huks/native_huks_api.h"
#include "huks/native_huks_param.h"
#include <string.h>
static napi_value DeleteKey(napi_env env, napi_callback_info info)
{
/* 1. Obtain the key alias. */
struct OH_Huks_Blob keyAlias = {
(uint32_t)strlen("test_key"),
(uint8_t *)"test_key"
};
/* 2. Call OH_Huks_DeleteKeyItem to delete the key. */
struct OH_Huks_Result ohResult = OH_Huks_DeleteKeyItem(&keyAlias, nullptr);
napi_value ret;
napi_create_int32(env, ohResult.errorCode, &ret);
return ret;
}
