Function Documentation

uint32_t nrf_crypto_rng_init

(

void

)

Initialize the random number generator.

Note

This function is called by nrf_crypto_init.

Return values

NRF_SUCCESS	If random number generator was initialized successfully.
NRF_ERROR_INTERNAL	If an internal error occured in the nrf_crypto backend.

uint32_t nrf_crypto_rng_vector_generate	(	uint8_t *	p_target,
		uint32_t	length
	)

Generate random data into a buffer, given length as an input.

Parameters

[in,out]	p_target	Pointer to a buffer to accept the random generated data. This buffer must be the same length as the length input.
[in]	length	Length (in bytes) to generate random data for.

Return values

NRF_SUCCESS	Data was generated successfully.
NRF_ERROR_NULL	p_target was NULL.
NRF_ERROR_INTERNAL	If an internal error occured in the nrf_crypto backend.
