The secure storage ITS store module.
The functions declared in this header implement the ITS store module. They are meant to be called only by the ITS implementation. This header may be included when providing a custom implementation of the ITS store module (
CONFIG_SECURE_STORAGE_ITS_STORE_IMPLEMENTATION_CUSTOM
).
psa_status_t secure_storage_its_store_get | ( | secure_storage_its_uid_t | uid, |
size_t | data_size, | ||
void * | data, | ||
size_t * | data_length ) |
Retrieves the data of an ITS entry from the storage medium.
[in] | uid | The entry's UID. |
[in] | data_size | The size of data in bytes. |
[out] | data | The buffer to which the entry's stored data is written. |
[out] | data_length | On success, the number of bytes written to data . May be less than data_size . |
`PSA_SUCCESS` | on success. |
`PSA_ERROR_DOES_NOT_EXIST` | if no entry with the given UID exists. |
`PSA_ERROR_STORAGE_FAILURE` | on any other failure. |
psa_status_t secure_storage_its_store_remove | ( | secure_storage_its_uid_t | uid | ) |
Removes an ITS entry from the storage medium.
uid | The entry's UID. |
PSA_SUCCESS
on success, anything else on failure. psa_status_t secure_storage_its_store_set | ( | secure_storage_its_uid_t | uid, |
size_t | data_length, | ||
const void * | data ) |
Writes the data of an ITS entry to the storage medium.
uid | The entry's UID. |
data_length | The number of bytes in data . |
data | The data to store. |
`PSA_SUCCESS` | on success. |
`PSA_ERROR_INSUFFICIENT_STORAGE` | if there is insufficient storage space. |
`PSA_ERROR_STORAGE_FAILURE` | on any other failure. |
