Declaration

#define PSA_MAC_TRUNCATED_LENGTH(mac_alg) \ (((mac_alg) & PSA_ALG_MAC_TRUNCATION_MASK) >> PSA_MAC_TRUNCATION_OFFSET)

Argument

Description

mac_alg

A MAC algorithm identifier (value of type #psa_algorithm_t such that #PSA_ALG_IS_MAC(\p mac_alg) is true).

Length of the truncated MAC in bytes. 0 if \p mac_alg is a non-truncated MAC algorithm. Unspecified if \p mac_alg is not a supported MAC algorithm.
