Struct Shake256 

pub struct Shake256 { /* private fields */ }

SHAKE256 extendable-output function (FIPS 202).

Implementations

impl Shake256

pub fn new() -> Self

Returns a new SHAKE256 instance with the standard domain.

pub fn with_domain(domain: u8) -> Result<Self, Error>

Returns a new SHAKE256 instance with a custom domain byte.

Errors

Returns Error::InvalidValue unless domain is in 0x01..=0x7f.

pub fn update<Input: Bytes + ?Sized>(&mut self, input: &Input)

Absorbs input.

pub fn finalize(self) -> Shake256Reader

Finishes absorbing and returns a reader for the output stream.

pub fn compute_into_bytes<Output: MutBytes + ?Sized, Input: Bytes + ?Sized>( output: &mut Output, input: &Input, )

Computes SHAKE256 of input with the standard domain, filling output.

pub fn compute_to_vec<Input: Bytes + ?Sized>( input: &Input, len: usize, ) -> Vec<u8>

Available on crate feature alloc only.

Computes len bytes of SHAKE256 of input with the standard domain.
