c4d1b514ab Define handles as key identifiers
Define psa_key_handle_t to be equal to
mbedtls_svc_key_id_t. Make the handle of a persistent
key be equal to its key identifier. For volatile keys,
make the key handle equal to the volatile key
identifier of the created volatile key.

The unit tests are modified just to make them compile
not to make them run successfully. They are fixed in
the subsequent commits.

9814fa2b08 Minor updates from review comments
Updated macros in config_psa.h that used ECC_xxx to use KEY_TYPE_ECC_xxx
per comments from review. Implemented a check_config_psa.h to help with
dependency checking of features enabled in config_psa.h. Added
check_config_psa.h to visual studio project.

7fc75eac21 Enable all features in crypto_config.h
In order to pass existing tests like test_psa_crypto_config_basic
and test_psa_crypto_config_no_driver, all the new features need
to be enabled in the default crypto_config.h file. This change
enables those features by default and updates the other new
tests to compensate for everything being enabled by disabling
some features for some of the tests as needed.

0e00519711 Add feature support for RSA for PSA crypto config
In the original attempt to add RSA support to PSA crypto config was too
generic. This set of changes adds support for the following RSA features:
PSA_WANT_ALG_RSA_PKCS1V15_CRYPT, PSA_WANT_ALG_RSA_PKCS1V15_SIGN,
PSA_WANT_ALG_RSA_OAEP, PSA_WANT_ALG_RSA_PSS, PSA_WANT_KEY_TYPE_RSA_KEY_PAIR,
and PSA_WANT_KEY_TYPE_RSA_PUBLIC_KEY.

There were also some updates to ensure the proper inclusion of PSA crypto
library code when certain features are enabled. These updates were made to
address warnings and errors in builds from the new tests for these
features being added for PSA crypto configuration.

f4c4cb008c Added additional support for ECP for PSA_CRYPTO_CONFIG
The KEY_TYPE_ECC_KEY_PAIR and KEY_TYPE_ECC_PUBLIC_KEY were previously
being guarded by MBEDTLS_ECP_C in the PSA crypto library code. This change
moves it to the new MBEDTLS_PSA_BUILTIN_xxx and separates KEY_PAIR
and PUBLIC_KEY as needed. Tests have also been added to validate the new
settings.

d032195278 Phase 2 support for MBEDTLS_PSA_CRYPTO_CONFIG
This phase adds in support for the following features being
added to the list of features that can be configured in the
include/psa/crypto_config.h header file using the PSA_WANT_ALG_xxx
macros: ECDH, HMAC, HKDF, and RSA. These changes include changes to
the PSA crypto library to use the appropriate new guards that
will allow the feature to be compiled in or out either using
new PSA_WANT_ALG_xxx or the previous MBEDTLS_xxx macros.

For HKDF and HMAC, most of the PSA library code did not have a
specific matching MBEDTLS_xxx macro for that feature, but was instead
using the generic dependent MBEDTLS_MD_C macro. The ECDH and RSA
features more closely aligned with a direct replacement with a similar
macro.

The new tests for RSA, HMAC, and HKDF would normally unset additional
dependent macros, but when attempting to implement that level of
testing it required removal of too many core features like MD_C, PK_C,
ECP_C and other low level features. This may point to additional phases of
work to complete the transition of these features to the new model.

28baa1f141 Fixed test_psa_want_ecdsa_disabled_software to use proper macros
Updated the test_psa_want_ecdsa_disabled_software to enable and disable
the correct macros to accomplish the desired test. The previous version
left out the disabling of additional macros to ensure items related
to MBEDTLS_ECDSA_C were also unset. The test was also missing the setting
of the accelerators MBEDTLS_PSA_ACCEL_ALG_ECDSA and DETERMINISTIC_ECDSA.

With the accelerators enabled the test portion had to be temporarily
disabled until the accelerator code is completed so the test will work
properly.

Updated the signature driver source to fix a compiler warning when
MBEDTLS_ECDSA_C is unset.

5e940c6068 Fix additional data length field check for CCM
The CCM specification (NIST SP 800-38C) mandates that the formatting of
the additional data length l(a) changes when it is greater _or equal_ to
2^16 - 2^8 (>= 0xFF00). Since such lengths are not supported in mbed TLS,
the operation should fail in such cases.

This commit fixes an off-by-one error which allowed encryption/decryption
to be executed when l(a) was equal to 0xFF00, resulting in an
incorrect/non-standard length format being used.

cipher and requires a whole number of blocks, but the total input size
is not a multiple of the block size."

Currently, there is a distinction between encryption and decryption
on whether INVALID_ARGUMENT or BAD_STATE is returned, but this is not
a part of the spec.

This fix ensures that PSA_ERROR_INVALID_ARGUMENT is returned
consistently on invalid cipher input sizes.

70d7fb0c2d Don't hardcode TLS 1.3 labels in test cases
ssl_tls1_3_keys.c exports a structure containing all labels used
in the TLS 1.3 key schedule, but the TLS 1.3 key scheduling unit
tests so far replicated those labels in the test file. In particular,
wrong label values in ssl_tls1_3_keys.c wouldn't have been caught
by the unit tests.

This commit modifies the TLS 1.3 key schedule unit tests to use
the TLS 1.3 labels as exported by ssl_tls1_3_keys.c. This not only
makes sure that those labels are correct, but also avoids hardcoding
their hex-encoding in the test file.

2ec2eaac31 Fix test issues with depends-hashes
Needed to make additional fixes so that when MBEDTLS_USE_PSA_CRYPTO
is defined, the depends-hashes test will succeed. There are two
versions of the ecdsa_verify_wrap() function, one with
MBEDTLS_USE_PSA_CRYPTO and when when it is not enabled. The non PSA
version is not using the md_alg parameter since it is not required.
The PSA version was using that parameter to derive a different value
it needed for PSA_ALG_ECDSA. The arguement of PSA_ALG_ECDSA is
ignored for psa_sign_hash and psa_verify_hash. It is present because
it is used and must be a valid hash, not zero, for psa_sign_hash
(but not psa_verify_hash) with PSA_ALG_DETERMINISTIC_ECDSA, and it is
needed for psa_sign_message and psa_verify_message which are not
implemented yet. The local parameter now uses PSA_ALG_ECDSA_ANY for
the verify function to avoid using the md_alg parameter and avoids
returning incorrect error codes.

71016a9ea7 psa: Rename psa_key_file_id_t to mbedtls_svc_key_id_t
With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.

The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.

The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.

As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
  MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT

27238fcbd8 psa: Use psa_key_file_id_t as the key id type
The purpose of this commit and the following is for
psa_key_id_t to always be as defined by the PSA
Cryptography API specification.

Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.

Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.

It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.

As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.

By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

The remaining ones are false positives for this regexp.

The errors only had minor consequences: the output of `ssl-opt.sh`
contained lines like
```
Renegotiation: gnutls server strict, client-initiated .................. ./tests/ssl-opt.sh: 741: printf: %S: invalid directive

```
and in case of failure the GnuTLS command containing a substring like
`--priority=NORMAL:%SAFE_RENEGOTIATION` was not included in the log
file. With the current tests, there was no risk of a test failure
going undetected.

ed9fbc6443 Clearer function name for parity check
Return a name that more clearly returns nonzero=true=good, 0=bad. We'd
normally expect check_xxx to return 0=pass, nonzero=fail so
check_parity was a bad name.

29c4a6cf9f Add negative tests for MAC verification
Add negative tests for psa_mac_verify_finish: too large, too small, or
a changed byte.

090e16cb8b Don't destroy the key during a MAC verification operation
An early draft of the PSA crypto specification required multipart
operations to keep working after destroying the key. This is no longer
the case: instead, now, operations are guaranteed to fail. Mbed TLS
does not comply yet, and still allows the operation to keep going.
Stop testing Mbed TLS's non-compliant behavior.

5e65cec5e8 Simplify output bounds check in mac_sign test
Rely on Asan to detect a potential buffer overflow, instead of doing a
manual check. This makes the code simpler and Asan can detect
underflows as well as overflows.
