Function Documentation

mcuxClRandomModes_createPatchMode()

mcuxClRandom_Status_t mcuxClRandomModes_createPatchMode	(	mcuxClRandom_ModeDescriptor_t *	patchMode,
		mcuxClRandomModes_CustomGenerateAlgorithm_t	customGenerateAlgorithm,
		mcuxClRandom_Context_t	pCustomCtx,
		uint32_t	securityStrength )

This function creates a PATCH_MODE descriptor.

This function creates a PATCH_MODE descriptor. The function expects as input a custom function to be used inside the CL functions for random number generation as well as a pointer to a context buffer which can be used by the custom generate function. The custom generate function may also use all CPU workarea allocated for the mcuxClRandom_generate function. The function shall be called prior to an mcuxClRandom_init call.

Parameters

patchMode[out]	Pointer to PATCH_MODE descriptor to be initialized
customGenerateAlgorithm[in]	Pointer to the custom generate function
pCustomCtx[in]	Pointer to a custom context which shall be used by the passed custom generate function
securityStrength[in]	Security level for which the patch DRBG shall be used

Returns

status
