Struct crypto_mac::Output

pub struct Output<M: Mac> { /* private fields */ }

Output is a thin wrapper around bytes array which provides a safe Eq implementation that runs in a fixed time.

Implementations

impl<M: Mac> Output<M>

pub fn new(bytes: GenericArray<u8, M::OutputSize>) -> Output<M>

Create a new MAC Output.

pub fn into_bytes(self) -> GenericArray<u8, M::OutputSize>

Get the MAC tag/code value as a byte array.

Be very careful using this method, since incorrect use of the tag value may permit timing attacks which defeat the security provided by the Mac trait.

Trait Implementations

impl<M: Clone + Mac> Clone for Output<M>where M::OutputSize: Clone,

fn clone(&self) -> Output<M>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<M: Mac> ConstantTimeEq for Output<M>

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

impl<M: Mac> PartialEq<Output<M>> for Output<M>

fn eq(&self, x: &Output<M>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
