psa_key_usage_t#
typedef uint32_t psa_key_usage_t
Encoding of permitted usage on a key.
Values of this type are generally constructed as bitwise-ors of macros called PSA_KEY_USAGE_xxx.
Note
Values of this type are encoded in the persistent key store. Any changes to existing values will require bumping the storage format version and providing a translation when reading the old format.
