Expand description

Encoding of identifiers of persistent keys.

  • Applications may freely choose key identifiers in the range #PSA_KEY_ID_USER_MIN to #PSA_KEY_ID_USER_MAX.
  • The implementation may define additional key identifiers in the range #PSA_KEY_ID_VENDOR_MIN to #PSA_KEY_ID_VENDOR_MAX.
  • 0 is reserved as an invalid key identifier.
  • Key identifiers outside these ranges are reserved for future use.

\note Values of this type are encoded in the persistent key store. Any changes to how values are allocated must require careful consideration to allow backward compatibility.
