Struct crypto::sha2::Sha256

pub struct Sha256 { /* fields omitted */ }

The SHA-256 hash algorithm with the SHA-256 initial hash value.

Methods

impl Sha256

pub fn new() -> Sha256

Construct an new instance of a SHA-256 digest.

Trait Implementations

impl Digest for Sha256

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

Provide message data.

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

Retrieve the digest result. This method may be called multiple times.

fn reset(&mut self)

Reset the digest. This method must be called after result() and before supplying more data.

fn output_bits(&self) -> usize

Get the output size in bits.

fn block_size(&self) -> usize

Get the block size in bytes.

fn output_bytes(&self) -> usize

Get the output size in bytes.

fn input_str(&mut self, input: &str)

Convenience function that feeds a string into a digest.

fn result_str(&mut self) -> String

Convenience function that retrieves the result of a digest as a String in hexadecimal format.

impl Clone for Sha256

fn clone(&self) -> Sha256

Returns a copy of the value.

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

Performs copy-assignment from source.
