Ronald Cron 9103d490e8 psa: ecdsa: Rework deterministic support check
Move the check that ECDSA is supported from the
caller of the function responsible for Mbed TLS
ECDSA signatures to this function, namely
mbedtls_psa_ecdsa_sign_hash().

This makes the caller code more readable and is
more aligned with what is expected from a
sign_hash() PSA driver entry point.

Add a negative test case where a deterministic
ECDSA signature is requested while the library
does not support deterministic ECDSA.

Steven Cooreman f9f7fdfe49 Rework MAC algorithm / key type validation
Reworked the validation of MAC algorithm with the used key type by
introducing psa_mac_key_can_do, which guarantees that PSA_MAC_LENGTH can
be called successfully after validation of the algorithm and key type.

This means psa_get_mac_output_length is no longer required.

Steven Cooreman 4ff9a29686 Check truncation length explicitly
Comparing algorithm with its FULL_LENGTH_MAC version doesn't work in
cases where algorithm is a wildcard. Wildcard input is not specified in
the documentation of the function, but in order to test the function
using the same test as PSA_MAC_LENGTH we're mimicking that behaviour here.

Paul Elliott c48cb80b1f Prevent false positive CF Test Failures
Marked dirty memory ends up in the result buffer after encoding (due to

to make sure that we got what we expected was triggering the constant
flow checker.

Steven Cooreman 1ac5ce3b91 Make psa_key_policy_algorithm_intersection MAC-length aware
This makes it more in-line with how psa_key_policy_permits works. It
also adds consistency: the intersection of MAC with default length and
MAC with exact-length is now computed correctly in case the exact length
equals the default length of the algorithm when used with the given
key type.
