Declaration

#define PSA_ALG_IS_HMAC(alg) \ (((alg) & (PSA_ALG_CATEGORY_MASK | PSA_ALG_MAC_SUBCATEGORY_MASK)) == \ PSA_ALG_HMAC_BASE)

Argument

Description

alg

An algorithm identifier (value of type #psa_algorithm_t).

1 if \p alg is an HMAC algorithm, 0 otherwise. This macro may return either 0 or 1 if \p alg is not a supported algorithm identifier.
