Function Documentation

mcuxClKey_Derivation_ModeConstructor_HKDF()

mcuxClKey_Status_t mcuxClKey_Derivation_ModeConstructor_HKDF	(	mcuxClKey_DerivationMode_t *	pDerivationMode,
		const mcuxClKey_DerivationAlgorithmDescriptor_t *	derivationAlgorithm,
		mcuxClMac_Mode_t	macMode,
		uint32_t	options
	)

Construct a key derivation function (KDF) mode according to RFC5869.

Parameters

[out]	pDerivationMode	Pointer to the key derivation mode structure to be initialized.
[in]	derivationAlgorithm	Function pointer to the key derivation algorithm function.
[in]	macMode	Mac mode type, must represent an HMAC mode.
[in]	options	Generic options field containing algorithm-specific parameters (currently not used).

When calling mcuxClKey_derivation function with this constructor additional inputs may be provided via mcuxClKey_DerivationInput_t inputs[] parameter array. Detailed description of possible inputs is provided for each algorithm type.
