Four days. A fresh 4.0 in hand, two talks at the podium, a Large Business Community convened for the first time, seventeen exhibitors in the hall, and a table on Thursday night that turned colleagues into comrades.

Tomáš Vávra walks the room through post-quantum cryptography in the OpenSSL Library — ML-KEM, ML-DSA, SLH-DSA, three FIPS standards, fifteen interop providers, and the one command that turns it all into a working TLS session.

Tim Hudson takes OpenSSL 4.0 to ICMC — the release that finally put SSL in the rearview, retired the ENGINE API after twenty-six years, and made the project's governance a matter of public record.

A field report from the OpenSSL Corporation team — somewhere between a cloudy runway view, a very stubborn booth panel, and the oldest saloon in Washington.

The final release of OpenSSL 4.0 is now live. We would like to thank all those who contributed to the OpenSSL 4.0 release, without whom the OpenSSL Library would not be possible.

From February 23–27, 2026, we gathered in Kedesh-Haven, Australia, for a week-long face-to-face meeting with colleagues from Bouncy Castle and cryptlib.

We announce the results of the Advisory Committees’ Elections. Following a three-week voting period held from February 2–20, 2026 (UTC), community members across the Academics, Committers, and Large Businesses communities have selected their representatives for the upcoming term.

We are pleased to announce a new cooperation agreement with the Faculty of Informatics at Masaryk University (FI MU), reinforcing secure and trustworthy cryptographic software, research, and education.

Effective January 1, 2026, we joined the Association of Industrial Partners at FI MU as a Small and medium enterprises member to foster closer collaboration with students and researchers, in areas of mutual interest, including cryptographic algorithms, security protocols and all aspects of the OpenSSL Library and its deployment in real-world environments.
