Notes from Excel@FIT 2026, and the wider Brno partnership that brought us to a fourteenth-century monastery on a perfectly ordinary morning in May.

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.

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.
