Struct CShake256 

pub struct CShake256 { /* private fields */ }

cSHAKE256: customizable SHAKE with 256-bit security (NIST SP 800-185).

If both function_name and customization are empty, cSHAKE256 reduces to SHAKE256 (the domain-separation prefix is omitted).

Implementations

impl CShake256

pub const RATE: usize = 136

Rate in bytes (same as SHAKE256).

pub fn new(function_name: &[u8], customization: &[u8]) -> Self

Create a new cSHAKE256 instance with a function name and customization string.

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

Absorb input data.

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

Squeeze output bytes. Can be called multiple times.
