Struct tiny_keccak::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);
