OQS-openssh 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/openssh-portable is an integration of liboqs into (a fork of) OpenSSH. 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 OpenSSH 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 OpenSSH was released on November 13, 2018. Its release page on Github is

What's New

This is the first snapshot release of the OQS fork of OpenSSH.

It is based on the upstream OpenSSH 7.7 portable 1 release.

It provides:

  • post-quantum key exchange in SSH 2
  • hybrid (post-quantum + elliptic curve) key exchange in SSH 2

It can build against either liboqs master branch or liboqs nist-branch.

Future work

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