Built-in keys#

Built-in key mechanism provides access to the keys stored in hardware.

It can be accessed using key ID that is in the range [MBEDTLS_PSA_KEY_ID_BUILTIN_MIN, MBEDLTS_PSA_KEY_ID_BUILTIN_MAX].

Note

Available builtin key IDs vary for different family of devices. For devices vith VSE see Builtin keys on devices with a VSE , and for devices with Secure Engine see Builtin keys on devices with Secure Engine .

Typedefs#

typedef uint64_t

A slot number identifying a key in a driver.

#define

MBEDTLS_PSA_KEY_ID_BUILTIN_MIN ((psa_key_id_t)0x7fff0000)

The minimum value for a key identifier that is built into the implementation.

#define

MBEDTLS_PSA_KEY_ID_BUILTIN_MAX ((psa_key_id_t)0x7fffefff)

The maximum value for a key identifier that is built into the implementation.

#define

MBEDTLS_PSA_KEY_ID_BUILTIN_MIN ((psa_key_id_t)0x7fff0000)

The minimum value for a key identifier that is built into the implementation.

#define

MBEDTLS_PSA_KEY_ID_BUILTIN_MAX ((psa_key_id_t)0x7fffefff)

The maximum value for a key identifier that is built into the implementation.

typedef uint64_t psa_drv_slot_number_t

A slot number identifying a key in a driver.

Values of this type are used to identify built-in keys.
