Nonce

Struct Nonce 

Source
pub struct Nonce(/* private fields */);
Expand description

A client-generated 64-byte nonce.

Zeroized on drop: the nonce is the one value this client generates itself that carries any unpredictability, so it is scrubbed as defense-in-depth even though the protocol does not treat it as a secret in the classic sense (see the crate-level security notes).

Implementations§

Source§

impl Nonce

Source

pub const fn new(bytes: [u8; 64]) -> Self

Wraps caller-supplied nonce bytes.

This is the no_std-safe constructor: a bare-metal caller supplies its own entropy (e.g. from a hardware RNG) rather than relying on an OS random source.

Source

pub const fn as_bytes(&self) -> &[u8; 64]

Returns the nonce’s raw bytes.

Source

pub fn random() -> Result<Self, Error>

Generates a nonce using the active crypto backend’s random source.

§Errors

Returns crate::Error::RandomUnavailable if the OS random source is unavailable.

impl Zeroize for Nonce

Source§

fn zeroize(&mut self)
