Struct flow_sdk::algorithms::sha3::Sha3

pub struct Sha3 { /* fields omitted */ }

The SHA3 hash functions defined in FIPS-202.

Usage

[dependencies]
tiny-keccak = { version = "2.0.0", features = ["sha3"] }

Example

let input = b"hello world";
let mut output = [0; 32];
let expected = b"\
    \x64\x4b\xcc\x7e\x56\x43\x73\x04\x09\x99\xaa\xc8\x9e\x76\x22\xf3\
    \xca\x71\xfb\xa1\xd9\x72\xfd\x94\xa3\x1c\x3b\xfb\xf2\x4e\x39\x38\
";
let mut sha3 = Sha3::v256();
sha3.update(input);
sha3.finalize(&mut output);
assert_eq!(expected, &output);

Trait Implementations

impl Clone for Sha3

pub fn clone(&self) -> Sha3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl FlowHasher for Sha3

type Algorithm = Sha3

The algorithm of this hasher.

fn new() -> Self

Creates a new hasher.

fn update<B: AsRef<[u8]> + ?Sized>(&mut self, bytes: &B)

Updates the hasher with bytes.

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

Finalize the hasher, returns the 256 bit hash.

impl Hasher for Sha3

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