Struct Sha384 

pub struct Sha384 { /* private fields */ }

SHA-384 hasher (FIPS 180-4). 384-bit output, 128-byte blocks.

SHA-384 reuses the SHA-512 internal compression function with different IV constants and a truncated output. Used by TLS 1.3 for the higher security tier (paired with P-384) and by FIPS 186-5 for the canonical P-384 ECDSA hash.

Trait Implementations

impl Clone for Sha384

fn clone(&self) -> Sha384

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hasher for Sha384

const OUTPUT_LEN: usize = 48

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.
