The final release of OpenSSL 3.5 is now live. We would like to thank all those who contributed to the OpenSSL 3.5 release, without whom the OpenSSL Library would not be possible.

The OpenSSL Corporation and the OpenSSL Foundation are pleased to announce the OpenSSL Conference 2025, taking place from October 7 to 9, 2025, in the historic city of Prague, Czech Republic. This premier event brings together a global community of cryptography experts, legal professionals, and open-source enthusiasts dedicated to advancing cryptography and secure communications for three days of in-depth discussions, insights, and networking.

On March 24 and 25, 2025, we hosted two live Q&A sessions to discuss the formation and role of the new Technical Advisory Committees (TACs) concerning the OpenSSL Library. These sessions featured:

• Tim Hudson, President of the OpenSSL Corporation (Session 1)
• Matt Caswell, President of the OpenSSL Foundation (Sessions 1 and 2)
• Anton Arapov, Operations Director of the OpenSSL Corporation (Session 2)
• Hana Andersen, Marcom Manager of the OpenSSL Corporation (both sessions)
• Moderated by Kajal Sapkota

These interactive webinars offered our community the opportunity to ask questions and better understand the purpose and structure of the TACs.

The OpenSSL Project is pleased to announce that OpenSSL 3.5 Beta1 pre-release is released and adding significant new functionality to the OpenSSL Library.

Thank you to everyone who registered and to those who went the extra mile to nominate candidates for the Technical Advisory Committees of the OpenSSL Corporation and OpenSSL Foundation.

The OpenSSL Corporation (primarily focused on commercial communities) and the OpenSSL Foundation (primarily focused on non-commercial communities) are pleased to announce the formation of the Technical Advisory Committees (TACs) to provide expert guidance and strategic direction for our technical initiatives. This marks a significant milestone, and we need dedicated individuals to help shape their future.

The OpenSSL Project is pleased to announce that OpenSSL 3.5 Alpha1 pre-release is released and adding significant new functionality to OpenSSL Library.

The OpenSSL Corporation is pleased to announce that OpenSSL version 3.1.2 has achieved FIPS 140-3 validation, signifying its compliance with the rigorous cryptographic module security requirements set forth by the National Institute of Standards and Technology (NIST). This accomplishment marks a significant milestone in reinforcing trusted, standards-based encryption for organizations operating in regulated environments, including government agencies, healthcare institutions, and financial services.

The OpenSSL Project is announcing the upcoming release of OpenSSL 3.5 Alpha, scheduled for March 11, 2025. As a result, the repository will be frozen before the release on March 6, 2025.

The included features can be found in the OpenSSL 3.5 Feature Go/No-Go Decision blog post.

We are pleased to announce that OpenSSL 3.5 will be the next long term stable (LTS) release. Per OpenSSL’s LTS policy, 3.5 will be supported until April 8, 2030.

The previous LTS (OpenSSL 3.0) will continue to be fully supported until September 7, 2025 and receive security fixes until September 7, 2026. Projects that currently depend on 3.0 are strongly encouraged to switch to OpenSSL 3.5 once it has been released.

In addition, the OpenSSL Corporation and Foundation have agreed to designate an LTS every two years. That means there will be an LTS release in April of 2027, another in 2029, and so on. As always, each LTS will be supported for 5 years with the final year’s support being security patches only. For more information, please see the OpenSSL Library Roadmap.
