Struct Kt128Rng 

pub struct Kt128Rng { /* private fields */ }

HPKE-compatible RNG using RFC 9861 KT128 (KangarooTwelve / TurboSHAKE128)

This implementation provides cryptographically secure random number generation using libQ’s KT128 (KangarooTwelve) primitive. K12 is significantly faster than SHAKE256 while maintaining the same security properties.

Implementations

impl Kt128Rng

pub fn new() -> Result<Self>

Create a new secure RNG with system entropy

Errors

Returns an error if entropy source is unavailable or fails to initialize.

pub fn from_seed(seed: &[u8]) -> Self

Create a new secure RNG with explicit seed

pub fn refill(&mut self)

Refill the internal buffer with new random data (advances the KT128 chain).
