Struct crypto::hmac::Hmac

pub struct Hmac<D> { /* fields omitted */ }

The Hmac struct represents an Hmac function - a Message Authentication Code using a Digest.

Methods

impl<D: Digest> Hmac<D>

pub fn new(digest: D, key: &[u8]) -> Hmac<D>

Create a new Hmac instance.

Arguments

• digest - The Digest to use.
• key - The key to use.

Trait Implementations

impl<D: Digest> Mac for Hmac<D>

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

Process input data.

fn reset(&mut self)

Reset the Mac state to begin processing another input stream.

fn result(&mut self) -> MacResult

Obtain the result of a Mac computation as a MacResult.

fn raw_result(&mut self, output: &mut [u8])

Obtain the result of a Mac computation as [u8]. This method should be used very carefully since incorrect use of the Mac code could result in permitting a timing attack which defeats the security provided by a Mac function.

fn output_bytes(&self) -> usize

Get the size of the Mac code, in bytes.
