A library-agnostic hybrid classic/PQ OpenSSL provider — built with AI
Wednesday October 14, 2026 09:30 - 10:00 CEST
Room 2
In last year's presentation on oqs-provider, we concluded with proposed next work, namely an OpenSSL provider for hybrid classic/PQ logic independent of a specific PQ library. This talk presents how this new provider was created with the help of an AI, its functional capabilities and the lessons learned: the former dwarf the ones of the original oqs-provider, and the latter may be helpful for others using the same tooling in the context of a somewhat security-related software component.

HSM-Backed OpenPGP Signing for OpenSSL Releases: Architecture and Operations
Wednesday October 14, 2026 11:30 - 12:00 CEST
Room 2
For most of OpenSSL's history a release was signed with the release manager's own OpenPGP key — the 1.1.1 and 3.0.0 tags carry signatures from different individuals. Automating the release process consolidated that onto one shared release key, but it was still a private key in a file on disk. Either way, the trust root for software that a large chunk of the internet depends on to build TLS was a file that could be copied. This talk covers moving that trust root onto hardware — an Entrust nShield HSM in FIPS 140-3 mode — without breaking release automation and without changing anything for verifiers. We cover: the two-tier key model (a Certify-only primary key under a card quorum, plus a signing subkey the pipeline uses unattended); sq-pkcs11, the open-source Rust CLI on Sequoia-OpenPGP we built to bridge OpenPGP and PKCS#11; the redesigned pipeline with an isolated signing stage; nshield-card-check, a small web app for custodians to verify their card and passphrase on demand with an audit trail; and generalizing the same HSM to sign RPM/DEB repos and Java code. Attendees leave with a concrete reference architecture that runs against SoftHSM2 as well as real hardware.
