Struct nucypher_core::SessionSecretFactory

pub struct SessionSecretFactory(_);

This class handles keyring material for session keys, by allowing deterministic derivation of SessionStaticSecret objects based on labels.

Implementations

impl SessionSecretFactory

pub fn random_with_rng(rng: &mut (impl CryptoRng + RngCore)) -> Self

Creates a session secret factory using the given RNG.

pub fn random() -> Self

Creates a session secret factory using the default RNG.

pub fn seed_size() -> usize

Returns the seed size required by

pub fn from_secure_randomness( seed: &[u8] ) -> Result<Self, InvalidSessionSecretFactorySeedLength>

Creates a SessionSecretFactory using the given random bytes.

Warning: make sure the given seed has been obtained from a cryptographically secure source of randomness!

pub fn make_key(&self, label: &[u8]) -> SessionStaticSecret

Creates a SessionStaticSecret deterministically from the given label.

Trait Implementations

impl Clone for SessionSecretFactory

fn clone(&self) -> SessionSecretFactory

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for SessionSecretFactory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SessionSecretFactory

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq<SessionSecretFactory> for SessionSecretFactory

fn eq(&self, other: &SessionSecretFactory) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
