lib-q-tweak-aead 0.0.4

//! Tweakable-block CTR AEAD using Keccak-f\[1600\] (SHA-3 permutation).
//!
//! Each 32-byte block uses an independent sponge evaluation (key, nonce, block counter),
//! enabling SIMD-parallel permutation. The tag is derived by absorbing
//! `key ‖ 0x03 ‖ nonce ‖ len(AD) ‖ AD ‖ len(CT) ‖ CT` into a fresh sponge.
//!
//! # Security
//!
//! The permutation is NIST-standardized; this **mode** is a custom construction and
//! requires independent analysis before production use.
