Field Documentation

◆ value

uint32_t mcuxClCss_HkdfOption_t::value

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

◆ rtfdrvdat

uint32_t mcuxClCss_HkdfOption_t::rtfdrvdat

MCUXCLCSS_CKDF_SYSTEM_MEMORY_DERIV=use derivation input from system memory, MCUXCLCSS_CKDF_RTF_DERIV=use RTF (runtime fingerprint) as derivation input

◆ hkdf_algo

uint32_t mcuxClCss_HkdfOption_t::hkdf_algo

Defines which algorithm shall be used.

This option is set internally and will be ignored: MCUXCLCSS_HKDF_ALGO_RFC5869 = Use RFC5869 algorithm MCUXCLCSS_HKDF_ALGO_SP80056C = Use SP800-56C algorithm
