liboqs-java is an open source Java wrapper for the liboqs C library. The Open Quantum Safe (OQS) project provides software for prototyping quantum-resistant cryptography.

Post-quantum cryptographic implementation of HQC (Hamming Quasi-Cyclic) - a NIST PQC candidate for quantum-resistant key encapsulation using code-based cryptography

The Performance of Post-Quantum Key Encapsulation Mechanisms - A study on Consumer, Cloud and Mainframe Hardware. The full paper with figures and LaTeX source

Profiling and benchmark data collected from instrumented post-quantum KEM implementations

Instrumented implementations of modern-day KEXs and future KEMs

Enable AES keys transfer on unsecure channel using quantum-resistant Kyber

A post-quantum secure messaging library for Typescript

Browser-based NTRU demo implementing the original 1996 Hoffstein-Pipher-Silverman lattice cryptosystem (EESS#1 v3.3, ees443ep1). Polynomial ring arithmetic from scratch — the lattice scheme that started it all.

Browser demo for ML-KEM (CRYSTALS-Kyber), the post-quantum key encapsulation mechanism standardized as NIST FIPS 203 in August 2024.

A post-quantum secure messaging library for Python

Browser-based FrodoKEM demo — plain LWE (no ring structure), key generation, encapsulation, decapsulation, error distribution, FrodoKEM vs ML-KEM comparison. The belt-and-suspenders post-quantum KEM. No backends. No simulated math.

This is the fourth project that was developed for the Cryptographic Structures class. Evaluated with a 'A' grade.

Browser-based demo of hybrid post-quantum key exchange — X25519 + ML-KEM-768 running in parallel, exactly as deployed in Chrome 124+, Cloudflare, and Signal. Secure against both classical and quantum attackers.

A simple, modern and secure encryption tool (and Go library) with small explicit keys, no config options, and UNIX-style composability.
