OQS-OpenSSL_1_1_1-stable snapshot 2020-08


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 in TLS 1.3, X.509 certificates, CMS, and S/MIME. The integration should not be considered "production quality".

Release notes

This is the 2020-08 snapshot release of OQS-OpenSSL, which was released on August 11, 2020. Its release page on GitHub is This release is intended to be used with liboqs version 0.4.0.

What's New

This is the fourth snapshot release of OQS-OpenSSL_1_1_1-stable. It is based on OpenSSL 1.1.1g.

  • Uses the updated NIST Round 2 submissions added to liboqs 0.4.0, as described in the liboqs release notes.


As a result of NIST's announcement of Round 3 of the Post-Quantum Cryptography Standardization Project, this is the last release of OQS-OpenSSL that contain algorithms from Round 2 that are not Round 3 finalists or alternate candidates. Those algorithms will be removed in the next release. The algorithms in question are: NewHope, ThreeBears, MQDSS, and qTesla. These algorithms are considered deprecated within OQS-OpenSSL will receive no updates after this release.
