Struct ring::aead::Nonce

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

A nonce for a single AEAD opening or sealing operation.

The user must ensure, for a particular key, that each nonce is unique.

Nonce intentionally doesn’t implement Clone to ensure that each one is consumed at most once.

Implementations§

source§

impl Nonce

source

pub fn try_assume_unique_for_key(value: &[u8]) -> Result<Self, Unspecified>

Constructs a Nonce with the given value, assuming that the value is unique for the lifetime of the key it is being used with.

Fails if value isn’t NONCE_LEN bytes long.

source

pub fn assume_unique_for_key(value: [u8; 12]) -> Self

Constructs a Nonce with the given value, assuming that the value is unique for the lifetime of the key it is being used with.

impl AsRef<[u8; 12]> for Nonce

fn as_ref(&self) -> &[u8; 12]
