Struct Poly1305 

pub struct Poly1305 { /* private fields */ }

RFC 8439 Poly1305 one-time authenticator.

Every key must be used for exactly one message. Reuse reveals the key.

Trait Implementations

impl Algorithm for Poly1305

const ID: &'static str = "poly1305"

Stable ontology identifier for this algorithm.

const NAME: &'static str = "Poly1305"

Human-facing display name (for example "SHA-256").

impl Clone for Poly1305

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for Poly1305

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Mac for Poly1305

const TAG_LEN: usize = 16

Tag length in bytes.

type Tag = [u8; 16]

The fixed-size tag type.

fn new(key: &[u8]) -> Result<Self>

Create a MAC instance from a key of any length the algorithm accepts.

fn update(&mut self, data: &[u8])

Absorb more input.

fn finalize(self) -> [u8; 16]

Consume the instance and produce the tag.

fn mac(key: &[u8], data: &[u8]) -> Result<Self::Tag, Error>

where Self: Sized,

One-shot authentication.

fn verify(key: &[u8], data: &[u8], tag: &[u8]) -> Result<(), Error>

where Self: Sized,

Constant-time tag verification.

impl SelfTest for Poly1305

fn self_test() -> Result<()>

Run the algorithm’s known-answer test.
