Gilles Peskine	a23eafce3a	Fix snprintf call to assume less about integral type sizes ... The code only worked if psa_key_id_t (formerly psa_key_slot_t) promoted to int and every value fit in int. Now the code only assumes that psa_key_id_t is less wide than unsigned long, which is the case since psa_key_id_t is a 32-bit type in our implementation.	2018-12-11 16:48:13 +01:00
Gilles Peskine	8d4919bc6a	Persistent storage implementation: psa_key_slot_t -> psa_key_id_t ... Move the persistent storage implementation from psa_key_slot_t to psa_key_id_t. For the most part, this just means changing the types of function arguments. Update the documentation of some functions to reflect the fact that the slot identifier is purely a storage identifier and is not related to how the slot is designated in memory.	2018-12-11 16:48:13 +01:00
Darryl Green	db2b8db715	psa: Add storage implementation for files ... Add new functions, psa_load_persistent_key(), psa_free_persistent_key_data(), and psa_save_persistent_key(), for managing persistent keys. These functions load to or save from our internal representation of key slots. Serialization is a concern of the storage backend implementation and doesn't abstraction-leak into the lifetime management code. An initial implementation for files is provided. Additional storage backends can implement this interface for other storage types.	2018-11-20 15:21:22 +00:00
