Struct wolf_crypto::mac::poly1305::Key

pub struct Key { /* private fields */ }

Represents a 32-byte secret key for Poly1305 and ChaCha20Poly1305.

This struct ensures that the key material is securely managed and zeroed from memory when dropped.

Implementations

impl Key

pub const fn new(inner: [u8; 32]) -> Self

Creates a new Key from a 32-byte array.

Arguments

• inner - A 32-byte array containing the key material.

Example

use wolf_crypto::mac::poly1305::Key;

let key_bytes = [0u8; 32];
let key = Key::new(key_bytes);

pub const fn as_ref(&self) -> KeyRef<'_>

Returns a reference to the key as a KeyRef.

Returns

• KeyRef - A reference to the key material.

Example

use wolf_crypto::mac::poly1305::{Key, KeyRef};

let key_bytes = [0u8; 32];
let key = Key::new(key_bytes);
let key_ref: KeyRef = key.as_ref();

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Key

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

Formats the value using the given formatter.

impl Drop for Key

fn drop(&mut self)

Drops the Key, ensuring that the key material is zeroed from memory.

impl From<[u8; 32]> for Key

fn from(value: [u8; 32]) -> Self

Converts a 32-byte array into a Key.

Arguments

• value - A 32-byte array containing the key material.

Example

use wolf_crypto::mac::poly1305::Key;

let key_bytes = [1u8; 32];
let key: Key = key_bytes.into();

impl Zeroize for Key

fn zeroize(&mut self)

Zeroes the key material in memory.

This method securely erases the key from memory to prevent leakage.
