starknet/falcon v11.4.2
Entry point of starknet/falcon: a signer for the S2morrow Falcon-512 account, a post-quantum
signature. Import it from starknet/falcon, not from starknet:
import { Falcon512Signer, falcon512 } from 'starknet/falcon';
const { secretKey, publicKey } = falcon512.generateKeyPair();
const mySigner = new Falcon512Signer(secretKey);
The Falcon code is a copy of @noble/post-quantum 0.7.1 (MIT, Paul Miller), with one addition:
signing and verifying a hash point computed outside noble, because the account hashes the
transaction with Poseidon, not with SHAKE256. This addition is proposed to noble in
https://github.com/paulmillr/noble-post-quantum/pull/55. Once noble publishes it,
starknet/falcon will use the npm package and drop the copy, with no change to its own API.
Status: Falcon as submitted to Round 3 of the NIST post-quantum standardization, not FN-DSA
(FIPS 206); noble has no independent audit (its author audited version 0.6.1); signing is not
constant-time. Details in the documentation of Falcon512Signer.
