Many secure elements and crypto accelerators require the use of wrapped keys and will not accept importing clear-text keys to their key store. The existing psa_import_key function could be augmented to support wrapped keys, but that puts the burden of identifying wrapping and associated parameters on the underlying implementation. A new function should be proposed to support wrapped key imports.
As there is no standard for key wrapping data formats and associated algorithms, this should be made generic enough to be adaptable to any such key stores.
Same need for exporting wrapped keys.
