Implementation of Chou-Orlandi Oblivious Transfer (OT) protocol

Work in progress

A n-out-of-1 OT protocol practical implementation in Rust, as thin as possible. The purpose is to learn how to use Rust crypto libraries.

Quickstart

cargo build
./target/debug/simplest-ot

Design

It uses Chou-Orlandi "Simplest OT" protocol to establish key exchange, and AES encryption for the actual information.
