Struct Sha512 

pub struct Sha512 { /* private fields */ }

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

64-bit oriented sibling of SHA-256, with twice the security level and roughly twice the throughput on 64-bit hardware. Used as the internal hash of Ed25519 (RFC 8032), as the canonical P-521 ECDSA hash (FIPS 186-5), and in TLS 1.3 / IPsec for the high-security tier.

Trait Implementations

impl Clone for Sha512

fn clone(&self) -> Sha512

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hasher for Sha512

const OUTPUT_LEN: usize = 64

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.
