Struct crypto::fortuna::Fortuna

pub struct Fortuna {
    // some fields omitted
}

The Fortuna CSPRNG (PC 9.5)

Methods

impl Fortuna

fn new_unseeded() -> Fortuna

Creates a new unseeded Fortuna (PC 9.5.4)

fn add_random_event(&mut self, s: u8, i: usize, e: &[u8])

Adds a random event e from source s to entropy pool i (PC 9.5.6)

Trait Implementations

impl Rng for Fortuna

fn fill_bytes(&mut self, dest: &mut [u8])

Generate a bunch of random data into dest (PC 9.5.5)

Failure modes

If the RNG has not been seeded, and there is less than MIN_POOL_SIZE bytes of data in the first accumulator pool, this function will fail the task.
