A Post-Quantum Hybrid Encryption for High-Load Systems in TypeScript

What is this post about? This paper presents QuarkDash Crypto (a quantum resistant hybrid encryption algorithm), an open-source TypeScript library implementing a hybrid encryption protocol resistant to quantum computer attacks. QuarkDash combines post-quantum key exchange based on Ring-LWE , a fast stream cipher ( ChaCha20 or Gimli ), a quantum-resistant KDF , and a SHAKE256-based MAC , as well as built-in mechanisms for protecting against replay and timing attacks. Benchmark results are presented demonstrating throughput of up to 2.8 GB/s and session setup time of approximately 10 ms , which outperforms classical asymmetric schemes ( RSA , ECC ) and is comparable to symmetric encryption ( AES ), but with additional quantum resistance. If you're not interested in the implementation details, you can skip straight to the TypeScript library . Introduction With the development of quantum computers, many widely used cryptographic algorithms ( RSA , ECC , DSA ) are becoming vulnerable to Sho
