Post-Quantum Algorithms in OpenSSL

Matt Caswell

Recently NIST published a number of post-quantum algorithm standards (ML-KEM, ML-DSA, and SLH-DSA). With these new NIST publications, OpenSSL is now prepared for implementation.

We’ve recently been receiving a lot of questions about these new standards so we wanted to make our position clear:

OpenSSL considering TLS 1.0/1.1 deprecation

Neil Horman

Recently, OpenSSL proposed the deprecation of TLS 1.0/1.1 and solicited community feedback on the idea.

Feedback on the proposal was generally split down the middle, with half of the respondents indicating immediate depreciation with near-term removal was acceptable, while the remainder of the respondents with affirmative opinions noted that they represent, or know of products whose environment disallowed updating to TLS1.2 or later, and would need to re-enable the deprecated features for the foreseeable future.

OpenSSL 3.4 alpha released

Neil Horman

OpenSSL 3.4 alpha 1 has now been made available.

Our Alpha releases are considered feature complete for the release, meaning that between now and the final release, only bug fixes are expected (if any). Notable features of this release are available in CHANGES.md within the source tarball.

Join Our Webinar on Debugging OpenSSL Applications

Kajal Sapkota

Debugging is a crucial aspect of developing and maintaining reliable software. However, debugging can become particularly challenging when applications incorporate diverse and complex components like OpenSSL. This webinar is designed to help you navigate these complexities.

OpenSSL is pleased to announce its participation as a Silver Sponsor at the upcoming International Cryptographic Module Conference (ICMC) 2024, taking place from 18th to 20th September. Visit our booth and attend our presentations to discover how we can help each other.

OpenSSL 3.4 Alpha release approaching

Neil Horman

The freeze date for OpenSSL 3.4 Alpha is rapidly approaching.

Alpha freeze approaching

The freeze date for OpenSSL 3.4 Alpha is rapidly approaching. Planned features are viewable on our 3.4 Planning page. If you have a feature on the planning page, please ensure that your associated PRs are posted, reviewed, and merged prior to the freeze date (Friday, Aug 30, 2024), or it will be postponed until the next release.

Mission Statement

We believe everyone should have access to security and privacy tools, whoever they are, wherever they are or whatever their personal beliefs are, as a fundamental human right.
