Crate vaea_ntt 

VaeaNTT — High-Performance Number Theoretic Transforms

NTT engine for lattice-based cryptography, optimized for ARM NEON (aarch64) with portable scalar fallback.

Quick Start

use vaea_ntt::ntt32::Ntt32Context;

// Any NTT-friendly prime < 2^28
let ctx = Ntt32Context::new(256, 8_380_417);

let mut data = vec![42u32; 256];
ctx.forward(&mut data);
ctx.inverse(&mut data);
assert!(data.iter().all(|&x| x == 42));

Post-Quantum Presets

use vaea_ntt::pq::{PqScheme, PqNtt};

// ML-DSA-65 (FIPS 204) — digital signatures, NIST Level 3
let ntt = PqNtt::new(PqScheme::MlDsa65);

Modules

Module	Use case
pq	Post-quantum presets for ML-DSA (FIPS 204)
ntt32	28-bit primes (< 2²⁸), ARM NEON vectorized
ntt64	60–62 bit primes for FHE (SEAL/OpenFHE compatible)
poly	Polynomials over Z_q[X]/(X^N+1) with 64-bit coefficients
rns	Multi-prime CRT (Residue Number System)

Features

Feature	Default	Description
std	on	Enables std::error::Error impl on NttError
rand	off	Random polynomial generation
ffi	off	C/C++/JS bindings via Diplomat

no_std

This crate is no_std compatible (requires alloc). Disable default features to use without std.
