Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.
check_config is the only module which enforces that SHA512 is
enabled together with SHA384.

Introduce MBEDTLS_X509_INFO to indicate the availability of the

are entirely unused. This saves several KB of code space.

Add implementation for MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS
Merging as it has been ready for four days now and I prefer not having to go through other rebases especially given the coming change of scope of development (3.0 rather than 2.2x).
The GCM interface now has separate functions to start the operation
and to pass the associated data.
This is in preparation for allowing the associated data to be passed
in chunks with repeatated calls to mbedtls_gcm_update_ad().

Alternative implementations of GCM may delay the output of partial
blocks from mbedtls_gcm_update(). Add an output length parameter to
mbedtls_gcm_update() to allow such implementations to delay the output
of partial blocks. With the software implementation, there is no such
delay.

Alternative implementations of GCM may delay the output of partial

mbedtls_gcm_update now accepts inputs of arbitrary size. There is no
longer a requirement that all calls except the last one pass a
multiple of 16 bytes.
This commit updates the library code and adjusts the GCM tests to
exercise arbitrarily aligned input sizes.
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
The existing GCM test suite only exercises the one-shot API. Also test
the multipart interface: systematically run it on the same test data,
with the input (plaintext or ciphertext) split in two parts.
Given the current limitations of the GCM API, the associated data is
always passed in a single shot to mbedtls_gcm_starts(), and the first
part of the input is a nonzero multiple of 16.

Replace all occurences of error code addition in the library with the new
MBEDTLS_ERROR_ADD macro.
Signed-off-by: Chris Jones <christopher.jones@arm.com>
The previous implementation of the error addition interface did not comply
with the invasive testing architecture guidelines. This commit fixes that
by:
- Renaming functions/macros/variables to follow the mbedtls_error_xxx or
mbedtls_test_hook_xxx convention.
- Making mbedtls_test_hook_error_add a global variable that can be set
by the testing code.
- Using a static inline function call, as opposed to macro, to keep
discrepancies between debug and production version to a minimum.

Fix builds where `MBEDTLS_ERROR_C` is not defined but `MBEDTLS_TEST_HOOKS`

`error.c` and error.h are the more logical place to keep this code and it
prevents issues with building `common.c` and conflicts with other projects
that use mbedtls (such as mbedOS).
`error.c` has been automatically generated by first adding the code to
`error.fmt` and then running `./scripts/generate_errors.pl`.
Also add parenthesis to the addition in `MBEDTLS_ERR_ADD`.

Fix building by adding `common.c` to the build scripts (both make and Cmake).
Also reworks the hook function pointer (also renamed to `err_add_hook`) to be

checking function.
Signed-off-by: Chris Jones <christopher.jones@arm.com>
`error.c` is a file generated from `error.h` and thus cannot contain the code
that was previously added. This commit fixes that issue by moving the
`MBEDTLS_ERR_ADD` macro and associated function and function pointer into
`common.h` and `common.c`.
Also fix a typo in `tests/include/test/helpers.h` where tabs were accidentally
used instead of spaces.
Signed-off-by: Chris Jones <christopher.jones@arm.com>
Adds a macro (`MBEDTLS_ERR_ADD`) to add error codes together and check that the
result will not be corrupted. This additional check is only enabled during
testing when `MBEDTLS_TEST_HOOKS` is defined.
Also includes a reference usage example in `rsa.c` where two high-level error
codes could be incorrectly added together under the right conditions. This now
ensures that when this error occurs during testing it will be correctly
reported.

Define algorithms for PureEdDSA and for HashEdDSA, the EdDSA variants
defined by RFC 8032.
The encoding for HashEdDSA needs to encode the hash algorithm so that
the hash can be calculated by passing PSA_ALG_SIGN_GET_HASH(sig_alg)
to psa_hash_compute() or psa_hash_setup(). As a consequence,
Ed25519ph (using SHA-512) and Ed448ph (using SHAKE256) need to have
different algorithm encodings (the key is enough to tell them apart,
but it is not known while hashing). Another consequence is that the
API needs to recognize the Ed448 prehash (64 bytes of SHAKE256 output)
as a hash algorithm.

Start generating storage format test cases. This commit introduces two test
data files: test_suite_psa_crypto_storage_format.v0.data for reading keys in
storage format version 0 (the current version at this time), and
test_suite_psa_crypto_storage_format.current.data for saving keys in the
current format (version 0 at this time).
This commit kicks off the test case generation with test cases to exercise
the encoding of usage flags. Subsequent commits will cover other aspects of
keys.
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
Save tests are for forward compatibility: import a key in the current format
and check that it has the expected storage format so that future versions
will still be able to read it.
Read tests are for backward compatibility: read a key in the format of a
past version (injected into storage) and check that this version can use it.
Exercise the key unless it is meant to test metadata storage only.
