Don't use the pk module except as required for pkparse/pkwrite. The
PSA crypto layer is meant to work alongside pk, not on top of it.
Fix the compile-time dependencies on RSA/ECP handling in
psa_export_key, psa_destroy_key and psa_get_key_information.
Define psa_key_type_t and a first stab at a few values.
New functions psa_import_key, psa_export_key, psa_destroy_key,
psa_get_key_information. Implement them for raw data and RSA.
Under the hood, create an in-memory, fixed-size keystore with room
for MBEDTLS_PSA_KEY_SLOT_COUNT - 1 keys.
Add a new function mbedtls_rsa_get_bitlen which returns the RSA key
size, i.e. the bit size of the modulus. In the pk module, call
mbedtls_rsa_get_bitlen instead of mbedtls_rsa_get_len, which gave the
wrong result for key sizes that are not a multiple of 8.
This commit adds one non-regression test in the pk suite. More tests
are needed for RSA key sizes that are a multiple of 8.
This commit does not address RSA alternative implementations, which
only provide an interface that return the modulus size in bytes.
New module psa_crypto.c (MBEDTLS_PSA_CRYPTO_C):
Platform Security Architecture compatibility layer on top of
libmedcrypto.
Implement psa_crypto_init function which sets up a RNG.
Add a mbedtls_psa_crypto_free function which deinitializes the
library.
Define a first batch of error codes.
Function test_snprintf() is called by run_test_snprintf() with constant test
data. It gets inlined and is subjected to snprintf format truncation checks
introduced by -Wformat-truncation in gcc-7. -Wformat-truncation is turned
On by -Wall and other similar options. It results in error with -Werror.
-Wformat-truncation makes tests performed by run_test_snprintf() redundant
on gcc. But they are still relevant for other compilers. This commit prevents
inlining of test_snprintf() to avoid gcc compile time checks.
Test suite header code was not gaurded with test suite dependency.
But some test suites have additional code in the headers section.
Variables in that section become unused if suite functions are
gaurded. Hence gaurded the headers section.
But this changed cuased missing types in get_expression() function
that was originally accessing types defined through suite headers.
Hence had to gaurd expressions code as well.
Gaurding expressions does not allow parsing the parameters when
some types or hash defs are gaurded. Hence added function
check_test() to check if test is allowed or not before parsing the
parameters.
- Separate string and hex parameter as unhexify is moved out of the function. It's input should only be hex.
- Fix test mbedtls_ccm_encrypt_and_tag that grows input message buffer with tag
- Add missing expected length parameter in ECP TLS tests
- Add deleted TEST_ASSERT and mbedtls calls that got removed in script based code generation
