Generate test cases for all key types. These test cases cover the key
representation (checked with export) and the encoding of the key type and
the bit-size.

Construct an object given the attributes and material for a PSA crypto key
and get the Mbed TLS storage representation.
The code to generate the storage representation was written based on the
specification in docs/architecture/mbed-crypto-storage-specification.md,
without looking at the code.
The data in the unit tests is from the AES-128 format_storage_data_check
test case in test_suite_psa_crypto_persistent_key.data, tweaked manually.
This commit creates a basic framework for using symbolic values for
attributes, but does not yet implement obtaining the corresponding numerical
values from an external source.

Make it possible to enumerate the key types, algorithms, etc.

This commit ensures that all fields of PSAMacroEnumerator are filled
by code inspection. Testing of the result may reveal more work to be

As I descovered, a changelog entry with a line length greater than 80
characters would still pass CI. This is a quick change to the script to
make it detect these descrepancies and fail.

There are type annotations that indirectly depend on the
typing_extensions module (on Python 3.5-3.7: Protocol was added to the
core typing module in 3.8). The typing_extensions module is not
installed by default, so the code didn't run on a pristine Python
installation.
To avoid depending on a non-default module, make the dependency on
typing_extensions optional. (It's still required to run mypy, but
installing mypy takes care of providing typing_extensions.) If it
isn't available, provide a substitute definition that's just good
enough to get the scripts to run.
Move this ugly code to its own module to avoid the temptation of
spreading such ugliness all over the place. It's likely to be used in
other modules anyway.

Otherwise the generation is sensitive to trivial differences such as
running `tests/scripts/generate_psa_tests.py` vs

SECP192R1 is declared in the PSA API specification, but it's an old
one that Mbed TLS doesn't support and even OpenSSL doesn't support.
We don't have test vectors for it. Just skip it.

Asymmetric keys can't just be arbitrary byte strings: the public key
has to match the private key and the private key usually has
nontrivial constraints.
In order to have deterministic test data and not to rely on
cryptographic dependencies in the Python script, hard-code some test
keys.
In this commit, copy some test keys from test_suite_psa_crypto.data.

New Python module intended to gather knowledge about key types and
cryptographic mechanisms, such as the ability to create test data for
a given key type and the determination of whether an algorithm is
compatible with a key type.
This commit just creates a class for knowledge about key types.

At the moment it makes no difference, but it could if e.g. a new

By default, exclude macros whose numerical value is not a valid member
of the semantic type (e.g. PSA_ALG_xxx_BASE is not itself an
algorithm, only an intermediate value used to construct others). But
do include them with include_intermediate=True, which
generate_psa_constants.py does.

Simplify the guards on MBEDTLS_ERROR_C and MBEDTLS_ERROR_STRERROR_DUMMY.
No longer include superfluous headers and definition: platform.h is

Code under MBEDTLS_USE_PSA_CRYPTO define is PSA client
code intended to use key identifiers of type psa_key_id_t.
Thus the MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
configuration option is incompatible with
MBEDTLS_USE_PSA_CRYPTO.
State this in config.h and check_config.h.
As a consequence:
. remove MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER from
the full configuration, as MBEDTLS_USE_PSA_CRYPTO is
part of it.
. add a new component in all.sh to keep testing the
library when MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
is set.

Provided a clearer comment for the description for ignoring
MBEDTLS_PSA_CRYPTO_CONFIG for full build setting.
Updated message output for test_psa_crypto_config_basic and
test_psa_want_ecdsa_disabled_software so it is more clear and
concise in what the test is doing. Removed inclusion of the
MBEDTLS_PSA_ACCEL_ALG_ECDSA since it should not have been used
for that particular tests.

With the new feature MBEDTLS_PSA_CRYPTO_CONFIG, needed to
add support that when the feature is disabled, if there
are defines like MBEDTLS_ECDSA_C defined, then the PSA_WANT_
equivalent define is also enabled. This ensures the guards in
the library psa_crypto will work properly.
Also fixed an error return code in the driver wrapper for cipher
encrypt setup so it will properly pass unit tests.
Ensured config.py full works properly with the new
MBEDTLS_PSA_CRYPTO_CONFIG, it should not be set when the full
option is used.
