Struct Kt128Expander 

pub struct Kt128Expander { /* private fields */ }

Expand a 256-bit seed (and optional domain) into an arbitrary-length byte stream via KT128.

Implementations

impl Kt128Expander

pub fn from_seed_32(domain: &'static [u8], seed: [u8; 32]) -> Self

Create an expander from a 32-byte seed and domain label.

pub fn from_seed(domain: &'static [u8], seed: &[u8]) -> Self

Create an expander from variable-length seed material and a domain label.

pub fn from_det_seed_32(seed: [u8; 32]) -> Self

Create an expander using DOMAIN_LIBQ_DET_RNG and a 32-byte seed.

pub fn from_det_u64(seed: u64) -> Self

Create an expander using DOMAIN_LIBQ_DET_RNG and SplitMix64-expanded u64 seed material.

pub fn refill(&mut self)

Refill the internal 32-byte buffer from the chained KT128 XOF step.

pub fn fill_bytes(&mut self, dest: &mut [u8])

Fill dest with deterministic pseudorandom bytes.
