Make some functions non-static, to avoid Wunused function warnings. Make
a function scoped variable block scoped instead, to avoid Wunused
variable warnings in some configurations.
Add parameters to psa_copy_key tests for the enrollment algorithm (alg2).
This commit only tests with alg2=0, which is equivalent to not setting
an enrollment algorithm.
Commit "Smoke-test operation contexts after setup+abort" replaced
{failed-setup; abort} sequences by {failed-setup; successful-setup}.
We want to test that, but we also want to test {failed-setup; abort}.
So test {failed-setup; abort; failed-setup; successful-setup}.
After a successful setup followed by abort, or after a failed setup
from an inactive state, a context must be usable. Test this for
hash, MAC and cipher contexts.
Calling psa_*_setup() twice on a MAC, cipher, or hash context should
result in a PSA_ERROR_BAD_STATE error because the operation has already
been set up.
Fixes#10
Extend hash bad order test in line with the new bad order tests for MAC
and cipher, covering more cases and making comments and test layout
consistent.
Ensure that when doing hash operations out of order, PSA_ERROR_BAD_STATE
is returned as documented in crypto.h and the PSA Crypto specification.
In multipart cipher tests, test that each step of psa_cipher_update
produces output of the expected length. The length is hard-coded in
the test data since it depends on the mode.
The length of the output of psa_cipher_finish is effectively tested
because it's the total output length minus the length produced by the
update steps.
The output length can be equal to the input length.
This wasn't noticed at runtime because we happened to only test with
CBC with the first chunk being a partial block.
Some calls to psa_cipher_finish or psa_cipher_update append to a
buffer. Several of these calls were not calculating the offset into
the buffer or the remaining buffer size correctly.
This did not lead to buffer overflows before because the buffer sizes
were sufficiently large for our test inputs. This did not lead to
incorrect output when the test was designed to append but actually
wrote too early because all the existing test cases either have no
output from finish (stream cipher) or have no output from update (CBC,
with less than one block of input).
Check generator validity (i.e. that alg has been initialized) before
allowing reads from the generator or allowing reads of the generator's
capacity.
This aligns our implementation with the documented error code behavior
in our crypto.h and the PSA Crypto API.
Test that freshly-initialized contexts exhibit default behavior through
the API. Do this without depending on the internal representation of the
contexts. This provides better portability of our tests on compilers
like MSVC.
For must-fail asymmetric decryption tests, add an output size parameter
so that tests can directly control what output buffer size they allocate
and use independently from the key size used. This enables better
testing of behavior with various output buffer sizes.
When RSA decrypting, unlike with RSA encrypting, we sometimes expect the
output length will be less than the key size. For instance, in the case
where the plaintext is zero-length we expect the output length of the
decryption to be zero-length as well, not key size in length.
For must-fail tests, we don't expect output-buffer-sized RSA-decryption,
only that the output length is less than or equal to the output size, so
these tests remain unchanged.
Change the must-pass tests to expect that the actual output size is
equal to the expected length of the output buffer instead of always
being the key size.
In one place, exercise_key was used in a such a way that if the test
failed inside exercise_key, the test suite would correctly report the
test as failed but would not report the exact location of the failure.
Fix this.
Add documentation for exercise_key that explains how to use it.
Split the testing into tests that exercise policies in
test_suite_psa_crypto and tests that exercise slot content (slot
states, key material) in test_suite_psa_crypto_slot_management.
Test various cases of source and target policies with and without
wildcards. Missing: testing of the policy constraint on psa_copy_key
itself.
Test several key types (raw data, AES, RSA). Test with the
source or target being persistent.
Add failure tests (incompatible policies, source slot empty, target
slot occupied).
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.
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.
Remove the type and bits arguments to psa_allocate_key() and
psa_create_key(). They can be useful if the implementation wants to
know exactly how much space to allocate for the slot, but many
implementations (including ours) don't care, and it's possible to work
around their lack by deferring size-dependent actions to the time when
the key material is created. They are a burden to applications and
make the API more complex, and the benefits aren't worth it.
Change the API and adapt the implementation, the units test and the
sample code accordingly.
You can use PSA_ALG_ANY_HASH to build the algorithm value for a
hash-and-sign algorithm in a policy. Then the policy allows usage with
this hash-and-sign family with any hash.
Test that PSA_ALG_ANY_HASH-based policies allow a specific hash, but
not a different hash-and-sign family. Test that PSA_ALG_ANY_HASH is
not valid for operations, only in policies.
Add new initializers for cipher operation objects and use them in our
tests and library code. Prefer using the macro initializers due to their
straightforwardness.
Add new initializers for MAC operation objects and use them in our tests
and library code. Prefer using the macro initializers due to their
straightforwardness.
Add new initializers for hash operation objects and use them in our
tests and library code. Prefer using the macro initializers due to their
straightforwardness.
Add new initializers for key policies and use them in our docs, example
programs, tests, and library code. Prefer using the macro initializers
due to their straightforwardness.
Change the way some lines are wrapped to cut at a more logical place.
