Nonce

rama::crypto::dep::aws_lc_rs::aead

Struct Nonce

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§

impl Nonce

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

§Errors

error::Unspecified when byte slice length is not NONCE_LEN

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

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