Merge pull request #3916 from jdurkop/psa-crypto-config-hashes-3672
Add support to crypto config for hashes
2020-12-07 13:50:56 +01:00
John Durkop d62b678473 Minor updates to address review comments
Removed unecessary checks on the ALG_SHA_224 and ALG_SHA_384 since
those are handled in config_psa.h by ensuring the correct _C is
included. Reformatted config_psa.h to be alphabetical and made the
assignments line up correctly for consistency. Fixed the guards
for ALG_SHA_224 and ALG_SHA_384 to be correct in the crypto library
source.

Gilles Peskine cd1495c037 In old-style PSA configuration, define PSA_WANT_xxx
When MBEDTLS_PSA_CRYPTO_CONFIG is disabled, if an Mbed TLS crypto
feature is enabled, declare the corresponding PSA feature as enabled,
in addition to enabling its software implementation. This is necessary
for code that uses PSA APIs and relies on PSA_WANT_xxx symbols to know
which features are enabled (application code, our library code using
MBEDTLS_USE_PSA_CRYPTO, our test dependencies, etc.).

Moved new check_crypto_config.h file from include/psa to library
directory and the file is now included from *.c instead of the
crypto_config.h file. Fixed guards in PSA crypto library based
on review comments for new PSA crypto config features.

John Durkop b6f7afcb5c Move check config feature for PSA_WANT
Moved from doing the dependency checks for MBEDTLS_PSA_BUILTIN to
checking the PSA_WANT macros for the dependency checks. This required
moving the file into the include/psa directory and having the file be
included by crypto_config.h instead of config_psa.h.

John Durkop 6ba40d1faa Corrected guards in PSA library based on review comments
Revised the placement of various new MBEDTLS_PSA_BUILTIN_xxx
guards based on review comments. Corrected guards in psa
test driver to use _ACCEL version instead of _BUILTIN version.
Updated check_config_psa.h to include additional dependency checks
for more algorithms. Renamed some of the new tests to be a little
more clear on the purpose.

Ronald Cron c3623dbc76 State PSA_CRYPTO_KEY_ID_ENCODES_OWNER and USE_PSA_CRYPTO incompatibility
Code under MBEDTLS_USE_PSA_CRYPTO define is PSA client
code intended to use key identifiers of type psa_key_id_t.
Thus the MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
configuration option is incompatible with
MBEDTLS_USE_PSA_CRYPTO.

State this in config.h and check_config.h.

As a consequence:
. remove MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER from
  the full configuration, as MBEDTLS_USE_PSA_CRYPTO is
  part of it.

. add a new component in all.sh to keep testing the
  library when MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
  is set.

Ronald Cron cf56a0a320 psa: Move from key handle to key identifier
Move all the PSA crypto APIs using key handles
to use key identifiers but psa_key_open() and
psa_key_close(). This is done without modifying
any test as key handles and key identifiers are
now the same.

Update the library modules using PSA crypto APIs
to get rid of key handles.

Programs and unit tests are updated to not use
key handles in subsequent commits, not in this
one.

John Durkop 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.

John Durkop 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.

John Durkop 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.

Gilles Peskine a26b3e56cb Only include config_psa.h from config.h with new-style PSA configuration
In old-style configuration, do not include mbedtls/config_psa.h from
mbedtls/config.h.

The inclusion should not and did not break any code, but it caused our
testing to miss a break of backward compatibility (fixed in "Include
config_psa.h from psa/crypto.h"). If users have their own config.h
which enabled MBEDTLS_PSA_CRYPTO_C and worked prior to the creation of
config_psa.h and MBEDTLS_PSA_CRYPTO_CONFIG, their config.h must keep
working. By including config_psa.h from config.h in the legacy case,
we weren't testing the legacy configuration mechanism adequately.
