Conflicts:
library/psa_crypto.c
tests/suites/test_suite_psa_crypto.data
tests/suites/test_suite_psa_crypto.function
All the conflicts are concurrent additions where the order doesn't
matter. I put the code from feature-psa (key policy) before the code
from PR #13 (key lifetime).
Conflict resolution:
* `tests/suites/test_suite_psa_crypto.data`: in the new tests from PR #14,
rename `PSA_ALG_RSA_PKCS1V15_RAW` to `PSA_ALG_RSA_PKCS1V15_SIGN_RAW` as
was done in PR #15 in the other branch.
New header file crypto_struct.h. The main file crypto.sh declares
structures which are implementation-defined. These structures must be
defined in crypto_struct.h, which is included at the end so that the
structures can use types defined in crypto.h.
Implement psa_hash_start, psa_hash_update and psa_hash_final. This
should work for all hash algorithms supported by Mbed TLS, but has
only been smoke-tested for SHA-256, and only in the nominal case.
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.
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.
