Function
Description
This function updates the state of the HMAC_DRBG context.
This function resets HMAC_DRBG context to the state immediately after initial call of mbedtls_hmac_drbg_init().
HMAC_DRBG context initialization. This function makes the context ready for mbedtls_hmac_drbg_seed(), mbedtls_hmac_drbg_seed_buf() or mbedtls_hmac_drbg_free().
This function reseeds the HMAC_DRBG context, that is extracts data from the entropy source.
This function turns prediction resistance on or off. The default value is off.
This function writes a seed file.
This function sets the amount of entropy grabbed on each seed or reseed. See the documentation of mbedtls_hmac_drbg_seed() for the default value.
Set the reseed interval. The reseed interval is the number of calls to mbedtls_hmac_drbg_random() or mbedtls_hmac_drbg_random_with_add() after which the entropy function is called again. The default value is #MBEDTLS_HMAC_DRBG_RESEED_INTERVAL.
This function reads and updates a seed file. The seed is added to this instance.
