pub struct Shake128 { /* private fields */ }

SHAKE128 extendable-output function (FIPS 202).

Implementations

impl Shake128

pub fn new() -> Self

Returns a new SHAKE128 instance with the standard domain.

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

Returns a new SHAKE128 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) -> Shake128Reader

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 SHAKE128 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 SHAKE128 of input with the standard domain.
