ntru

Overview

The NTRU Prime post-quantum asymmetric cypher compiled to WebAssembly using Emscripten. A simple JavaScript wrapper is provided to make NTRU easy to use in web applications.

The default parameter set is sntrup1277 (roughly 256-bit strength).

Example Usage

import {ntru} from 'ntru';

const keyPair /*: {privateKey: Uint8Array; publicKey: Uint8Array} */ =
	await ntru.keyPair()
;

const {cyphertext, secret} /*: {cyphertext: Uint8Array; secret: Uint8Array} */ =
	await ntru.encrypt(keyPair.publicKey)
;

const decrypted /*: Uint8Array */ =
	await ntru.decrypt(cyphertext, keyPair.privateKey) // same as secret
;

console.log(keyPair);
console.log(secret);
console.log(cyphertext);
console.log(decrypted);

Changelog

Breaking changes in major versions:

4.0.0:

• Switched from legacy NTRUEncrypt to NTRU Prime. For backwards compatibility with previous versions of this package, use ntru-legacy.

3.0.0:

• As part of upgrading from asm.js to WebAssembly (with asm.js included as a fallback), the API is fully asynchronous.

2.0.0:

• Removed some undocumented functions as part of minor API cleanup.
