test_psa_constant_names.py was originally written before the split of
crypto.h into crypto_values.h and more, so it now needs to read
crypto_values.h as well.
In both generate_psa_constants.py and test_psa_constant_names.py, read
crypto_extra.h as well. We don't currently define any value there, but
it's plausible that we will one day.
psa_status_t is currently a signed type where only non-negative values
are used, which makes things a bit awkward. For now, non-negative
values trigger an error. This code will need to be revised if we
switch to using negative values as error codes.
Calls to PSA_ALG_AEAD_WITH_DEFAULT_TAG_LENGTH and
PSA_ALG_FULL_LENGTH_MAC are not in canonical form, so exclude them
from the list of constructor macros to test.
Test psa_constant_names on many inputs. For each input, find out the
numerical value by compiling and running a C program, pass the
numerical value to psa_constant_names and compare the output with the
original input.
Gather inputs by parsing psa/crypto.h and
test_suite_psa_crypto_metadata.data. For macros that take an argument,
list some possible arguments using the parsed data.
Remove extra status handling code from psa_import_key_into_slot(). This
helps save a tiny amount of code space, but mainly serves to improve the
readability of the code.
Move pk-using code to inside psa_import_rsa_key(). This aligns the shape
of psa_import_rsa_key() to match that of psa_import_ec_private_key() and
psa_import_ec_public_key().
Remove front matter from our EC key format, to make it just the contents
of an ECPoint as defined by SEC1 section 2.3.3.
As a consequence of the simplification, remove the restriction on not
being able to use an ECDH key with ECDSA. There is no longer any OID
specified when importing a key, so we can't reject importing of an ECDH
key for the purpose of ECDSA based on the OID.
Use the PSA-native status type in psa_key_agreement_ecdh() in
preparation for us calling PSA functions (and not just Mbed TLS
functions) and still being able to return a psa_status_t (without having
to translate it to a Mbed TLS error and then back again).
Remove pkcs-1 and rsaEncryption front matter from RSA public keys. Move
code that was shared between RSA and other key types (like EC keys) to
be used only with non-RSA keys.
