Hashing operations

Required methods

fn name(&self) -> &'static str[src]

The string that the Noise spec defines for the primitive

fn block_len(&self) -> usize[src]

The block length for the primitive

fn hash_len(&self) -> usize[src]

The final hash digest length for the primitive

fn reset(&mut self)[src]

Reset the internal state

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

Provide input to the internal state

fn result(&mut self, out: &mut [u8])[src]

Get the resulting hash

Provided methods

fn hmac(&mut self, key: &[u8], data: &[u8], out: &mut [u8])[src]

Calculate HMAC, as specified in the Noise spec.

NOTE: This method clobbers the existing internal state

fn hkdf(
    &mut self,
    chaining_key: &[u8],
    input_key_material: &[u8],
    outputs: usize,
    out1: &mut [u8],
    out2: &mut [u8],
    out3: &mut [u8]
)[src]

Derive keys as specified in the Noise spec.

NOTE: This method clobbers the existing internal state
