Group psa_crypto_client

group Functions defined by a client provider

The functions in this group are meant to be implemented by providers of the PSA Crypto client interface. They are provided by the library when MBEDTLS_PSA_CRYPTO_C is enabled.

Note

All functions in this group are experimental, as using alternative client interface providers is experimental.

Functions

int psa_can_do_hash(psa_algorithm_t hash_alg)

Check if PSA is capable of handling the specified hash algorithm.

This means that PSA core was built with the corresponding PSA_WANT_ALG_xxx set and that psa_crypto_init has already been called.

Note

When using the built-in version of the PSA core (i.e. MBEDTLS_PSA_CRYPTO_C is set), for now, this function only checks the state of the driver subsystem, not the algorithm. This might be improved in the future.

Parameters:

hash_alg – The hash algorithm.

Returns:

1 if the PSA can handle hash_alg, 0 otherwise.

int psa_can_do_cipher(psa_key_type_t key_type, psa_algorithm_t cipher_alg)

Tell if PSA is ready for this cipher.

Note

When using the built-in version of the PSA core (i.e. MBEDTLS_PSA_CRYPTO_C is set), for now, this function only checks the state of the driver subsystem, not the key type and algorithm. This might be improved in the future.

Parameters:

• key_type – The key type.

• cipher_alg – The cipher algorithm.

Returns:

1 if the PSA can handle cipher_alg, 0 otherwise.
