Summary

Declaration

#define PSA_ALG_GET_HASH(alg) \ (((alg) & 0x000000ff) == 0 ? ((psa_algorithm_t) 0) : 0x02000000 | ((alg) & 0x000000ff))

Argument

Description

alg

An algorithm identifier (value of type #psa_algorithm_t).

The underlying hash algorithm if alg is a composite algorithm that uses a hash algorithm. \c 0 if alg is not a composite algorithm that uses a hash.
