psa_key_policy_permits() function
Test whether a policy permits an algorithm. The caller must test usage flags separately.
Syntax
static psa_status_t psa_key_policy_permits(const psa_key_policy_t *policy,
psa_key_type_t key_type,
psa_algorithm_t alg);
Return value
PSA_SUCCESS When \p alg is a specific algorithm allowed by the \p policy. PSA_ERROR_INVALID_ARGUMENT When \p alg is not a specific algorithm PSA_ERROR_NOT_PERMITTED When \p alg is a specific algorithm, but the \p policy does not allow it.
Notes
This function requires providing the key type for which the policy is being validated, since some algorithm policy definitions (e.g. MAC) have different properties depending on what kind of cipher it is combined with.

Description
Restrict a key policy based on a constraint.
Validate that a key policy is internally well-formed. This function only rejects invalid policies. It does not validate the consistency of the policy with respect to other attributes of the key such as the key type.
