FIPS 205 (Initial Public Draft) Stateless Hash-Based Digital Signature Standard written in pure Rust for server, desktop, browser and embedded applications. The code repository includes C FFI and Python bindings.
This crate implements the FIPS 205 draft standard in pure Rust with minimal and mainstream dependencies. All
twelve (!!) security parameter sets are fully functional. The implementation does not require the standard library,
e.g. #[no_std]
, has no heap allocations, e.g. no alloc
needed, and exposes the RNG
so it is suitable for the
full range of applications from server down to the bare-metal. The API is stabilized and the code is heavily biased
towards safety and correctness; further performance optimizations will be implemented as the standard matures.
This crate will quickly follow any changes to FIPS 205 as they become available.
See https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.205.ipd.pdf for a full description of the target functionality.
The functionality is extremely simple to use, as demonstrated by the following example.
use fips205::slh_dsa_shake_128s; // Could use any of the twelve security parameter sets.
use fips205::traits::{SerDes, Signer, Verifier};
# use std::error::Error;
#
# fn main() -> Result<(), Box<dyn Error>> {
let msg_bytes = [0u8, 1, 2, 3, 4, 5, 6, 7];
// Generate key pair and signature
let (pk1, sk) = slh_dsa_shake_128s::try_keygen_vt()?; // Generate both public and secret keys
let sig_bytes = sk.try_sign_ct(&msg_bytes, true)?; // Use the secret key to generate signature
// Serialize the public key, and send with message and signature bytes
let (pk_send, msg_send, sig_send) = (pk1.into_bytes(), msg_bytes, sig_bytes);
let (pk_recv, msg_recv, sig_recv) = (pk_send, msg_send, sig_send);
// Deserialize the public key, then use it to verify the msg signature
let pk2 = slh_dsa_shake_128s::PublicKey::try_from_bytes(&pk_recv)?;
let v = pk2.try_verify_vt(&msg_recv, &sig_recv)?;
assert!(v);
# Ok(())
# }
