kyber-crystals

Overview

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

The default parameter set is Kyber-1024 (roughly 256-bit strength).

Example Usage

import {kyber} from 'kyber-crystals';

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

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

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

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