Sha256Hasher

Struct Sha256Hasher 

Source
pub struct Sha256Hasher { /* private fields */ }
Available on (crate features hash-blake3 or hash-sha2) and crate feature hash-sha2 only.
Expand description

Streaming SHA-256 hasher for inputs that don’t fit in memory.

§Example

use crypt_io::hash::Sha256Hasher;

let mut h = Sha256Hasher::new();
h.update(b"first ");
h.update(b"second");
let d = h.finalize();
assert_eq!(d.len(), 32);

Implementations§

Source§

impl Sha256Hasher

Source

pub fn new() -> Self

Construct a fresh hasher.

Source

pub fn update(&mut self, data: &[u8]) -> &mut Self

Absorb data into the running hash. Returns &mut Self so calls can chain.

Source

pub fn finalize(self) -> [u8; 32]

Finalise the hash and return the 32-byte digest. Consumes the hasher.
