@unknownncat/curve25519-node

English version: README.en.md

Implementacao para Node.js com API limpa:

• x25519 e ed25519 via node:crypto (OpenSSL)
• axlsign compativel com legado, acelerado por backend Rust/WASM interno
• sem namespace wasm
• sem namespace napi

Instalar

npm i @unknownncat/curve25519-node

Uso rapido

import { randomBytes } from "node:crypto";
import { asBytes32, x25519, ed25519, axlsign } from "@unknownncat/curve25519-node";

const seedA = asBytes32(randomBytes(32));
const seedB = asBytes32(randomBytes(32));

const alice = x25519.generateKeyPair(seedA);
const bob = x25519.generateKeyPair(seedB);
const shared = x25519.sharedKey(alice.private, bob.public);

const msg = new TextEncoder().encode("hello");
const sig = ed25519.sign(seedA, msg);
const ok = ed25519.verify(ed25519.publicKey(seedA), msg, sig);

const axlSig = axlsign.sign(alice.private, msg, randomBytes(64));
const axlOk = axlsign.verify(alice.public, msg, axlSig);

CommonJS:

const { x25519, ed25519, axlsign } = require("@unknownncat/curve25519-node");

Exports

• x25519
• ed25519
• axlsign
• aliases top-level: sharedKey, sharedKeyStrict, generateKeyPair, sign, verify, signMessage, openMessage
• tipos/helpers: Bytes32, Bytes64, asBytes32, asBytes64

Observacoes

• sign/verify top-level seguem semantica Ed25519 e rejeitam opt_random.
• Para fluxo legado compativel com curve25519-js, use axlsign.*.
• Se voce precisa de WASM no navegador, use @unknownncat/curve25519-browser.
