Field Documentation

◆ value

uint32_t mcuxClEls_CkdfOption_t::value

Accesses the bit field as a full word; initialize with a combination of constants from MCUXCLELS_HKDF_VALUE_.

◆ ckdf_algo

uint32_t mcuxClEls_CkdfOption_t::ckdf_algo

Defines which algorithm and mode shall be used.

This option is set internally and will be ignored: MCUXCLELS_CKDF_ALGO_SP800108 = Use SP800-108 algorithm
