Struct HashEngine

pub struct HashEngine(/* private fields */);

Engine to compute SHA512/256 hash function.

SHA512/256 is a hash function that uses the sha512 algorithm but it truncates the output to 256 bits. It has different initial constants than sha512 so it produces an entirely different hash compared to sha512. More information at https://eprint.iacr.org/2010/548.pdf.

Trait Implementations

impl Clone for HashEngine

fn clone(&self) -> HashEngine

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for HashEngine

fn default() -> HashEngine

Returns the “default value” for a type.

impl HashEngine for HashEngine

const BLOCK_SIZE: usize = 128usize

Length of the hash’s internal block size, in bytes.

type MidState = [u8; 64]

Byte array representing the internal state of the hash engine.

fn midstate(&self) -> [u8; 64]

Outputs the midstate of the hash engine. This function should not be used directly unless you really know what you’re doing.

fn n_bytes_hashed(&self) -> usize

Return the number of bytes already n_bytes_hashed(inputted).

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

Add data to the hash engine.
