## Detailed Description

Internal command option bit field for CKDF functions.

## Field Documentation

## ◆ value

uint32_t mcuxClCss_CkdfOption_t::value

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

## ◆ ckdf_algo

uint32_t mcuxClCss_CkdfOption_t::ckdf_algo

Defines which algorithm and mode shall be used.

This option is set internally and will be ignored: MCUXCLCSS_CKDF_ALGO_SP800108 = Use SP800-108 algorithm
