Trait Implementations

impl AlgorithmFactory for RNGFactory

fn default_128_bit() -> Self

Get the default configured algorithm at the 128-bit security level.

fn default_256_bit() -> Self

Get the default configured algorithm at the 256-bit security level.

fn new(alg_name: &str) -> Result<Self, FactoryError>

Get an instance of the algorithm by name.

impl Default for RNGFactory

fn default() -> Self

Returns the “default value” for a type.

impl RNG for RNGFactory

fn add_seed_keymaterial( &mut self, additional_seed: &dyn KeyMaterialTrait, ) -> Result<(), RNGError>

Provide additional key material to be mixed in to the existing RNG instance. The exact behaviour will be implementation-specific, but this is intended for injecting additional entropy, not as the primary method of seeding the RNG.

fn next_int(&mut self) -> Result<u32, RNGError>

Returns the next random 32-bit integer.

fn next_bytes(&mut self, len: usize) -> Result<Vec<u8>, RNGError>

Returns the number of requested bytes.

fn next_bytes_out(&mut self, out: &mut [u8]) -> Result<usize, RNGError>

Returns the number of bytes written. The entire output buffer is zeroized before the random bytes are written.

fn fill_keymaterial_out( &mut self, out: &mut dyn KeyMaterialTrait, ) -> Result<usize, RNGError>

Fill the provided KeyMaterial with random bytes.

fn security_strength(&self) -> SecurityStrength

Returns the Security Strength of this RNG.
