mbedtls_hmac_drbg_write_seed_file() function

The HMAC_DRBG context.

The name of the file.

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 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.
