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

psa_drv_slot_number_t

A slot number identifying a key in a driver.

Macros#

#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)

Typedef Documentation#

psa_drv_slot_number_t#

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.

Macro Definition Documentation#

MBEDTLS_PSA_KEY_ID_BUILTIN_MIN#

#define MBEDTLS_PSA_KEY_ID_BUILTIN_MIN

Value:

((psa_key_id_t)0x7fff0000)

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

The range of key identifiers from MBEDTLS_PSA_KEY_ID_BUILTIN_MIN to MBEDTLS_PSA_KEY_ID_BUILTIN_MAX within the range from PSA_KEY_ID_VENDOR_MIN and PSA_KEY_ID_VENDOR_MAX and must not intersect with any other set of implementation-chosen key identifiers.

This value is part of the library's ABI since changing it would invalidate the values of built-in key identifiers in applications.

MBEDTLS_PSA_KEY_ID_BUILTIN_MAX#

#define MBEDTLS_PSA_KEY_ID_BUILTIN_MAX

Value:

((psa_key_id_t)0x7fffefff)

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

See MBEDTLS_PSA_KEY_ID_BUILTIN_MIN for more information.

MBEDTLS_PSA_KEY_ID_BUILTIN_MIN#

#define MBEDTLS_PSA_KEY_ID_BUILTIN_MIN

Value:

((psa_key_id_t)0x7fff0000)

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

This value is part of the library's ABI since changing it would invalidate the values of built-in key identifiers in applications.

MBEDTLS_PSA_KEY_ID_BUILTIN_MAX#

#define MBEDTLS_PSA_KEY_ID_BUILTIN_MAX
