Detailed Description

The CTR_DRBG context structure.

Field Documentation

mbedtls_aes_context aes_ctx

The AES context.

unsigned char counter[16]

The counter (V).

size_t entropy_len

The amount of entropy grabbed on each seed or reseed operation.

int(* f_entropy) (void *, unsigned char *, size_t)

The entropy callback function.

void* p_entropy

The context for the entropy function.

int prediction_resistance

This determines whether prediction resistance is enabled, that is whether to systematically reseed before each random generation.

int reseed_counter

The reseed counter.

int reseed_interval

The reseed interval.
