\brief The CTR_DRBG context structure.

Fields

counter: [c_uchar; 16]

< The counter (V).

reseed_counter: c_int

< The reseed counter. This is the number of requests that have been made since the last (re)seeding, minus one. Before the initial seeding, this field contains the amount of entropy in bytes to use as a nonce for the initial seeding, or -1 if no nonce length has been explicitly set (see mbedtls_ctr_drbg_set_nonce_len()).

prediction_resistance: c_int

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

entropy_len: usize

< The amount of entropy grabbed on each seed or reseed operation, in bytes.

reseed_interval: c_int

< The reseed interval. This is the maximum number of requests that can be made between reseedings.

aes_ctx: mbedtls_aes_context

< The AES context.

f_entropy: Option<unsafe extern "C" fn(arg1: *mut c_void, arg2: *mut c_uchar, arg3: usize) -> c_int>

p_entropy: *mut c_void

< The context for the entropy function.
