OQS-OpenSSL_1_1_1-stable snapshot 2018-11


The Open Quantum Safe (OQS) project has the goal of developing and prototyping quantum-resistant cryptography. More information on OQS can be found on our website: and on Github at

liboqs is an open source C library for quantum-resistant cryptographic algorithms.

open-quantum-safe/openssl is an integration of liboqs into (a fork of) OpenSSL. The goal of this integration is to provide easy prototyping of quantum-resistant cryptography. The integration should not be considered "production quality".

This branch of our fork of OpenSSL aims to provide integration of post-quantum algorithms from liboqs into TLS 1.3 in OpenSSL 1.1.1.

This branch of our fork of OpenSSL can be used with the following versions of liboqs:

  • liboqs master branch 0.1.0
  • liboqs nist-branch 2018-11 snapshot

Release notes

This snapshot of the OQS fork of OpenSSL 1.1.1 (OQS-OpenSSL_1_1_1-stable) was released on November 13, 2018. Its release page on Github is

What's New

This is the first snapshot release of OQS-OpenSSL_1_1_1-stable.

It is based on the upstream OpenSSL 1.1.1 release.

It provides:

  • post-quantum key exchange in TLS 1.3
  • hybrid (post-quantum + elliptic curve) key exchange in TLS 1.3
  • post-quantum authentication in TLS 1.3

It can build against either liboqs master branch or liboqs nist-branch. If building against liboqs nist-branch, post-quantum authentication is not enabled.

Future work

Snapshot releases of OQS-OpenSSL_1_1_1-stable will be made approximately bi-monthly. These will include syncing the branch with upstream releases of OpenSSL, and changes required to sync with new releases of liboqs.
