int nrf_cc3xx_platform_entropy_get	(	uint8_t *	buffer,
		size_t	length,
		size_t *	olen )

#include <crypto/nrf_cc310_platform/include/nrf_cc3xx_platform_entropy.h>

Function to generate entropy using Arm CryptoCell cc3xx.

This API corresponds to mbedtls_hardware_poll. It provides TRNG using the Arm CryptoCell cc3xx hardware accelerator.

Note

This API is only usable if nrf_cc3xx_platform initialization APIs was run prior to calling it.

Parameters

[out]	buffer	Pointer to buffer to hold the entropy data.
[in]	length	Length of the buffer to fill with entropy data.
[out]	olen	Pointer to variable that will hold the length of generated entropy.

Return values

0	on success

Returns

Any other error code returned from mbedtls_hardware_poll
