Open Source Summit India 2026

This hands-on workshop gives attendees a ground-up understanding of post-quantum cryptography and then puts that knowledge to work immediately. We start with the essentials: why classical public-key cryptography breaks under quantum attack, what NIST's post-quantum standardization process produced (ML-KEM, ML-DSA, SLH-DSA), and how hybrid key exchange lets you transition incrementally without abandoning classical security. Then, a hands-on using the Open Quantum Safe project's oqs-provider plugin for OpenSSL 3, attendees will:
Install and configure oqs-provider against a standard OpenSSL 3 installation
Generate post-quantum and hybrid X.509 certificates using ML-KEM and ML-DSA
Spin up a TLS 1.3 server and connect to it with a PQ-enabled openssl s_client
Inspect negotiated ciphersuites and key exchange algorithms in live TLS handshakes
Benchmark classical vs. hybrid vs. pure PQ handshake performance and understand the tradeoffs
Explore the algorithm catalogue — KEMs, signature schemes, and their NIST standardization status
No prior post-quantum knowledge is assumed. Attendees should be comfortable with Linux CLI and have a basic understanding of TLS.
