The secure storage ITS transform module.
The functions declared in this header implement the ITS transform 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 transform module (
CONFIG_SECURE_STORAGE_ITS_TRANSFORM_IMPLEMENTATION_CUSTOM
).

Transforms the data of an ITS entry for storage.
[in] | uid | The entry's UID. |
[in] | data_len | The number of bytes in data . |
[in] | data | The data to transform for storage. |
[in] | create_flags | The entry's create flags. It must contain only valid PSA_STORAGE_FLAG_* values. It gets stored as part of stored_data . |
[out] | stored_data | The buffer to which the transformed data is written. |
[out] | stored_data_len | On success, the number of bytes written to stored_data . |
PSA_SUCCESS
on success, anything else on failure.
