Public Release (1.1.0)

v.1.1.0

Meet the updated QuarkDash Crypto. This version provide a production-ready optimization for heavy calculations inside.

What's new in 1.1.0?

• Refactored and optimized ChaCha and Gimli ciphers;
• Optimized pure TypeScript SHAKE256 and MAC implementation (speed-up x10 times);
• Added WASM implementation (written on C) for SHAKE256 implementation with fallback if not supported;

Public Release (1.0.8)

Reasoning

This release includes security fixes based on Math.random unsafe function in QuarkDash Key Exchange module. Issue

Changelog

• Changed Math.random in QuarkDashKeyExchange to QuarkDashUtils.randomBytes;
• Added stable errorPoly() method implementation;

Now the key exchange is more secured by native crypto methods at web applications.

Public Release (1.0.5)

For CCA-security reasons created a new release with Ring-LWE changes (shared secret security).

Changelog:

• Added SHA-256 and SHA-512 implementation;
• Added Shared secret hash function using SHA-256;
• Changed Ring-LWE calls of QuarkDashKeyExchange;

What's New?

• CCA-security for shared secrets;

Public Release (1.0.2)

An updated version of the QuarkDash algorithm that includes minor changes to the algorithm without changing the core API.

New Features:

• Added Chi-Square test;
• Shake-256 Implementation now based on Keccak function instead SHA-256 emulation;

Public Release (1.0.0)

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.

❓ Why QuarkDash Crypto?

🔹 Lightweight library with zero dependencies;

🔹 Powerful crypto algorithm written in Typescript;

🔹 Extremely fast (great for realtime and IoT applications);

🔹 Production ready with benchmarks;

🔒 General Components

• 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.

⭐ Key Features

• 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.
