#include <crypto/nrf_cc310_platform/include/nrf_cc3xx_platform_hmac_drbg.h>

Function that initializes an hmac_drbg context.

Note

If the context is NULL the function uses an internal context.

Parameters

[in,out]	context	Pointer to structure holding the hmac_drbg context which must be used for subsequent calls to generate random data.
[in]	pers_string	Personalization string used for the HMAC_DRBG_Instantiate_algorithm.
[in]	pers_string_len	Length of the personalization string in bytes, which may be zero.

Returns
