Struct Shake256 

pub struct Shake256 { /* private fields */ }

Incremental SHAKE256 context for multi-part absorb and squeeze.

This is the primary hash interface used by the SLH-DSA hash wrappers in super::hash. Data is absorbed in parts via absorb, then the final output is obtained via finalize (which consumes the context) or squeeze (which allows multiple squeeze calls).

Implementations

impl Shake256

pub fn new() -> Self

Create a new SHAKE256 context ready for absorbing.

pub fn absorb(&mut self, data: &[u8])

Absorb input data. Can be called multiple times before squeezing.

pub fn squeeze(&mut self, out: &mut [u8])

Squeeze output bytes. Can be called multiple times for streaming output.

pub fn finalize(self, out_len: usize) -> Vec<u8>

Finalize and return exactly out_len bytes of output, consuming the context.
