HMAC_DRBG initial seeding.
int mbedtls_hmac_drbg_reseed(mbedtls_hmac_drbg_context *ctx, const unsigned char *additional, size_t len)
This function reseeds the HMAC_DRBG context, that is extracts data from the entropy source.
void mbedtls_hmac_drbg_init(mbedtls_hmac_drbg_context *ctx)
HMAC_DRBG context initialization.
void mbedtls_hmac_drbg_set_reseed_interval(mbedtls_hmac_drbg_context *ctx, int interval)
Set the reseed interval.
void mbedtls_hmac_drbg_free(mbedtls_hmac_drbg_context *ctx)

int mbedtls_hmac_drbg_seed_buf(mbedtls_hmac_drbg_context *ctx, const mbedtls_md_info_t *md_info, const unsigned char *data, size_t data_len)
Initilisation of simpified HMAC_DRBG (never reseeds).
void mbedtls_hmac_drbg_set_entropy_len(mbedtls_hmac_drbg_context *ctx, size_t len)
This function sets the amount of entropy grabbed on each seed or reseed.
int mbedtls_hmac_drbg_random_with_add(void *p_rng, unsigned char *output, size_t output_len, const unsigned char *additional, size_t add_len)
This function updates an HMAC_DRBG instance with additional data and uses it to generate random data.
int mbedtls_hmac_drbg_random(void *p_rng, unsigned char *output, size_t out_len)
This function uses HMAC_DRBG to generate random data.
