mlkem / crystals-kyber-js
An ML-KEM (NIST FIPS 203) and CRYSTALS-KYBER implementation written in TypeScript.
[Documentation for main](https://dajiaji.github.io/crystals-kyber-js/docs/main/)
This module is based on
[ntontutoveanu/crystals-kyber-javascript](https://github.com/antontutoveanu/crystals-kyber-javascript),
but includes the following improvements:
- ✅ Written in TypeScript.
- ✅ Available on various JavaScript runtimes: Browsers, Node.js, Deno,
Cloudflare Workers, etc.
- ✅ Deterministic key generation support.
- ✅ Constant-time validation for ciphertext.
- ✅ Better performance: 1.4 to 1.8 times faster than the original
implementation.
- ✅ Tree-shaking friendly.
- ✅ Fix [KyberSlash](https://kyberslash.cr.yp.to/index.html) vulnerability.
- ✅ ML-KEM ([NIST FIPS 203](https://csrc.nist.gov/pubs/fips/203/final))
support.
- ✅ Passed all the tests published by:
- [post-quantum-cryptography/KAT/MLKEM](https://github.com/post-quantum-cryptography/KAT/tree/main/MLKEM)
- [C2SP/CCTV/ML-KEM](https://github.com/C2SP/CCTV/tree/main/ML-KEM)
- [pq-crystals/kyber](https://github.com/C2SP/CCTV/tree/main/ML-KEM) (10000
consecutive tests)
This repository has the following packages:
| package | registry | description |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| crystals-kyber-js | [](https://www.npmjs.com/package/crystals-kyber-js) | `v1.x` implements CRYSTALS-KYBER, and `v2.x-` implements ML-KEM (NIST FIPS 203). `crystals-kyber-js` may become deprecated in the near future. Instead, we recommend switching to the following `mlkem` or `@dajiaji/mlkem`. |
| mlkem | [](https://www.npmjs.com/package/mlkem) | Implements only ML-KEM (NIST FIPS 203). It is an alias for the above `crystals-kyber-js` starting from `v2` onwards. We recommend using this package going forward. |
| @dajiaji/mlkem | [](https://jsr.io/@dajiaji/mlkem) | Implements only ML-KEM (NIST FIPS 203). It is an ML-KEM package for [jsr.io](https://jsr.io/). The above `mlkem` is an npm package of `@dajiaji/mlkem`, which has been converted using [@deno/dnt](https://github.com/denoland/dnt). |
For Node.js, you can install `mlkem` or `crystals-kyber-js` via npm, yarn or
pnpm:
```sh
# RECOMMENTED using `mlkem`
npm install mlkem
# `crystals-kyber-js` is still available for use, but it may become deprecated in the near future.
npm install crystals-kyber-js
```
Then, you can use it as follows:
```ts
import { MlKem768 } from "mlkem"; // or from "crystals-kyber-js"
async function doMlKem() {
// A recipient generates a key pair.
const recipient = new MlKem768(); // MlKem512 and MlKem1024 are also available.
const [pkR, skR] = await recipient.generateKeyPair();
//// Deterministic key generation is also supported
// const seed = new Uint8Array(64);
// globalThis.crypto.getRandomValues(seed); // node >= 19
// const [pkR, skR] = await recipient.deriveKeyPair(seed);
// A sender generates a ciphertext and a shared secret with pkR.
const sender = new MlKem768();
const [ct, ssS] = await sender.encap(pkR);
// The recipient decapsulates the ciphertext and generates the same shared secret with skR.
const ssR = await recipient.decap(ct, skR);
// ssS === ssR
return;
}
try {
doMlKem();
} catch (err: unknown) {
console.log("failed:", (err as Error).message);
}
```

## Installation
### Node.js
```sh
# Using npm:
npm install mlkem # or crystals-kyber-js
yarn add mlkem # or crystals-kyber-js
pnpm install mlkem # or crystals-kyber-js
# Using jsr:
npx jsr add @dajiaji/mlkem
yarn dlx jsr add @dajiaji/mlkem
pnpm dlx jsr add @dajiaji/mlkem
```
### Deno
Starting from version 2.0.0, `@dajiaji/mlkem` is available from the
[jsr.io](https://jsr.io). From this version onwards, please use JSR import
instead of HTTPS import in Deno.
**JSR import (`>=2.0.0`):**
Add `@dajiaji/mlkem` package using the commands below:
```sh
deno add @dajiaji/mlkem
```
Then, you can use the module from code like this:
```ts
import { MlKem1024, MlKem512, MlKem768 } from "@dajiaji/mlkem";
```
**HTTPS import (deprecated):**
```ts
import {
Kyber1024,
Kyber512,
Kyber768,
} from "https://deno.land/x/crystals_kyber@/mod.ts";
```
### Cloudflare Workers
```sh
# Using npm:
npm install mlkem # or crystals-kyber-js
yarn add mlkem # or crystals-kyber-js
pnpm install mlkem # or crystals-kyber-js
# Using jsr:
npx jsr add @dajiaji/mlkem
yarn dlx jsr add @dajiaji/mlkem
pnpm dlx jsr add @dajiaji/mlkem
```
```ts
import { MlKem1024, MlKem512, MlKem768 } from "@dajiaji/mlkem";
```
### Bun
```sh
# Using npm:
npm install mlkem # or crystals-kyber-js
yarn add mlkem # or crystals-kyber-js
pnpm install mlkem # or crystals-kyber-js
# Using jsr:
bunx jsr add @dajiaji/bhttp
```
```ts
import { MlKem1024, MlKem512, MlKem768 } from "@dajiaji/mlkem";
```
### Web Browsers
Followings are how to use this module with typical CDNs. Other CDNs can be used
as well.
```html
// Using esm.sh:
import { MlKem512, MlKem768, MlKem1024 } from "https://esm.sh/mlkem@<SEMVER>";
// Using unpkg.com:
// import { MlKem768 } from "https://unpkg.com/mlkem@SEMVER";
// ...
```
## Usage
This section shows some typical usage examples.

import { MlKem768 } from "mlkem";
// const { MlKem768 } = require("mlkem");
async function doMlKem() {
const recipient = new MlKem768();
const [pkR, skR] = await recipient.generateKeyPair();
const sender = new MlKem768();
const [ct, ssS] = await sender.encap(pkR);
const ssR = await recipient.decap(ct, skR);
// ssS === ssR
return;
}
try {
doMlKem();
} catch (err) {
console.log("failed: ", err.message);
}
```
### Deno, Cloudflare Workers and Bun
```ts
import { MlKem512 } from "@dajiaji/mlkem";
async function doMlKem() {
const recipient = new MlKem512();
const [pkR, skR] = await recipient.generateKeyPair();
const sender = new MlKem512();
const [ct, ssS] = await sender.encap(pkR);
const ssR = await recipient.decap(ct, skR);
// ssS === ssR
return;
}
try {
doMlKem();
} catch (err: unknown) {
console.log("failed:", (err as Error).message);
}
```
### Browsers
```html
import { MlKem1024 } from "https://esm.sh/mlkem";
globalThis.doMlKem = async () => {
try {
const recipient = new MlKem1024();
const [pkR, skR] = await recipient.generateKeyPair();
const sender = new MlKem1024();
const [ct, ssS] = await sender.encap(pkR);
const ssR = await recipient.decap(ct, skR);
// ssS === ssR
