Browser-based 1-of-2 Oblivious Transfer — the Simplest OT protocol (Chou-Orlandi 2015) over Curve25519 with real Edwards25519 (Ed25519) point arithmetic and AES-256-GCM encryption. Receiver gets exactly one message, sender learns nothing about which. Foundational primitive for secure MPC. Part of crypto-lab.
