Open Quantum Safe

software for prototyping
quantum-resistant cryptography

The Open Quantum Safe (OQS) project is an open-source project that aims to support the development and prototyping of quantum-resistant cryptography.

OQS consists of two main lines of work: liboqs, an open source C library for quantum-resistant cryptographic algorithms, and prototype integrations into protocols and applications, including the widely used OpenSSL library. These tools support research by ourselves and others.

All of our development takes place on our Github repositories. We welcome new contributors interested in joining our team. We are grateful to our financial sponsors and the companies who contribute in-kind developer time.
