lux-crypto-slhdsa

Canonical Rust binding for Lux SLH-DSA (FIPS 205, the final standardized form of SLH-DSA (FIPS 205, formerly SPHINCS+)).

Status: stub — luxcpp/crypto/slhdsa/c-abi/c_slhdsa.cpp returns CRYPTO_ERR_NOTIMPL. The Rust binding is shipped against the canonical C-ABI surface; KAT-vector roundtrip tests are gated #[ignore] until the C-ABI body lands. Tracked at #slhdsa-c-abi-impl.

Use

use lux_crypto_slhdsa::{keygen, sign, verify, Mode};

let mode = Mode::Sha2_128f;
let mut pk = vec![0u8; mode.pk_len()];
let mut sk = vec![0u8; mode.sk_len()];
keygen(mode, &seed, &mut pk, &mut sk)?;

Modes

Mode	NIST level	pk	sk	sig
Sha2_128f	L1	32	64	17088
Sha2_192f	L3	48	96	35664
