In cipher_test_verify_output_multpart, tweak the ways chunk sizes are
added in order to get rid of the variable temp. In other functions,
this commit does not change the logic at all.
Only whitespace changes.
* Remove tabs.
* Remove trailing whitespace.
* Correct some misindented lines.
* Normalize whitespace around some punctuation.
* Split some lines to avoid going over 80 columns.
cipher_test_positive was never compiled due to a syntax error in the
BEGIN_CASE magic comment. It has now been duplicated as
cipher_test_encrypt. Remove the copy that was never compiled.
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.
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.
