sd_rand_application_vector_get()

uint32_t sd_rand_application_vector_get	(	uint8_t *	p_buff,
		uint8_t	length )

#include <nrf_soc.h>

Generate NIST SP 800-90A compliant random numbers.

Parameters

[out]	p_buff	Pointer to uint8_t buffer for storing the bytes.
[in]	length	Number of bytes to place in p_buff.

Generating secure randoms is expensive in terms of time and power, so if security is not required, a pseudorandom number generator should be used instead.

Return values

NRF_SUCCESS	The requested bytes were written to p_buff.
NRF_ERROR_INVALID_ADDR	p_buff invalid.
NRF_ERROR_INVALID_STATE	The random number generator must be seeded using sd_rand_seed_set.
