QuarkDash Crypto - It is a hybrid cryptographic protocol that provides post-quantum security, high performance, and attack resistance. This library can be used as shared solution for client and server. Written on pure typescript. Dependency-free.
🔹 Lightweight library with zero dependencies;
🔹 Powerful crypto algorithm written in Typescript;
🔹 Extremely fast (great for realtime and IoT applications);
🔹 Production ready with benchmarks;
- Asymmetric key exchange – Ring-LWE (N=256, Q=7681) based on NTT;
- Symmetric encryption – With ChaCha20 (RFC 7539) or lightweight Gimli ciphers.
- Key Derivation Function (KDF) – Based on fast SHAKE256 (emulated via SHA-256).
- Message Authentication Code (MAC) – Based on SHAKE256 with key.
- Replay protection – timestamp + sequence number.
- Quantum stability – not broken by Shor and Grover's algorithms;
- Performance – encryption up to 2.8 GB/s, session establishment ~10 ms;
- Forward secrecy – compromising a long-term key does not reveal past sessions.
- Built-in protection against replay, timing attacks, and counterfeiting.
- Flexibility – choice of cipher (ChaCha20/Gimli), synchronous and asynchronous API.
You can use the QuarkDash library as a regular library for both Backend and Frontend applications without any additional dependencies.
Installation using NPM:
npm install quarkdashOr using GitHub:
git clone https://github.com/devsdaddy/quarkdash
cd ./quarkdash/* Import modules */
import {CipherType, QuarkDash, QuarkDashUtils} from "../src";
/* Alice - client, bob - server, for example for key-exchange */
const alice = new QuarkDash({ cipher: CipherType.Gimli });
const bob = new QuarkDash({ cipher: CipherType.Gimli });
/* Generate key pair */
const alicePub = await alice.generateKeyPair();
const bobPub = await bob.generateKeyPair();
/* Initialize session at bob and jpin alice public key */
const ciphertext = await alice.initializeSession(bobPub, true) as Uint8Array;
await bob.initializeSession(alicePub, false);
await bob.finalizeSession(ciphertext);
/* Encrypt by alice and decrypt by bob */
const plain = QuarkDashUtils.textToBytes('Hello QuarkDash 🔒!');
const enc = await alice.encrypt(plain);
const dec = await bob.decrypt(enc);
console.log("Decrypted:", QuarkDashUtils.bytesToText(dec));| Command | Usage |
