Struct Sha512_256 

pub struct Sha512_256 { /* private fields */ }

SHA-512/256 hasher (FIPS 180-4). 256-bit output, 128-byte blocks.

Uses the SHA-512 compression function with a distinct IV and a 32-byte truncation. Provides 128-bit collision resistance (same as SHA-256) but runs on the 64-bit oriented SHA-512 core, which is faster than SHA-256 on 64-bit platforms.

Trait Implementations

impl Clone for Sha512_256

fn clone(&self) -> Sha512_256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hasher for Sha512_256

const OUTPUT_LEN: usize = 32

Output size in bytes.

const BLOCK_LEN: usize = 128

Block size in bytes (for HMAC computation).

fn new() -> Self

Create a new hasher instance.

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

Feed data into the hasher (can be called multiple times).

fn finalize(self) -> Vec<u8>

Finalize and return the digest. Consumes the hasher.

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

Finalize into a caller-provided buffer (no allocation).

fn hash(data: &[u8]) -> Vec<u8>

where Self: Sized,

One-shot: hash data and return the digest.
