## Detailed Description

The CTR_DRBG context structure.

Definition at line 126 of file ctr_drbg.h.

## Field Documentation

## ◆ aes_ctx

mbedtls_aes_context mbedtls_ctr_drbg_context::aes_ctx

The AES context.

Definition at line 138 of file ctr_drbg.h.

## ◆ counter

unsigned char mbedtls_ctr_drbg_context::counter[16]

The counter (V).

Definition at line 128 of file ctr_drbg.h.

## ◆ entropy_len

size_t mbedtls_ctr_drbg_context::entropy_len

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

Definition at line 134 of file ctr_drbg.h.

## ◆ f_entropy

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

The entropy callback function.

Definition at line 143 of file ctr_drbg.h.

## ◆ p_entropy

void* mbedtls_ctr_drbg_context::p_entropy

The context for the entropy function.

Definition at line 146 of file ctr_drbg.h.

## ◆ prediction_resistance

int mbedtls_ctr_drbg_context::prediction_resistance

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

Definition at line 130 of file ctr_drbg.h.

## ◆ reseed_counter

int mbedtls_ctr_drbg_context::reseed_counter

The reseed counter.

Definition at line 129 of file ctr_drbg.h.

## ◆ reseed_interval

int mbedtls_ctr_drbg_context::reseed_interval

The reseed interval.
