wolfSSL Post-Quantum Cryptography Example

This directory contains:

• A server application that perform a completely quantum-safe TLS 1.3 connection.
• A client application that perform a completely quantum-safe TLS 1.3 connection with the server above.
• An STM32CubeIDE project for doing quantum-safe TLS 1.3 connection over UART and some applications that run on the Linux side to connect with it.

Prerequisites

Build wolfSSL with support for ML-KEM (Kyber) and ML-DSA (Dilthium

./autogen.sh
./configure --enable-kyber --enable-dilithium
make all
sudo make install
sudo ldconfig

Building the Server and Client

$ make

Quantum safe TLS 1.3 Connection

client-pq-tls13 will connect with server-pq-tls13 via a completely quantum- safe connection. Authentication will be done via the ML-DSA signature scheme. Ephemeral key establishment will be done via ML-KEM. Both are standardized by NIST. Please see https://github.com/wolfSSL/osp/tree/master/oqs/README.md for instructions about certificate generation. For your convenience, certificates and keys have already been generated and are in this repo's certs directory.

In a terminal, execute the server:

./server-pq-tls13

In another terminal, execute the client:

./client-pq-tls13 127.0.0.1

The client will be prompted for a message to send to the server. Once you see this prompt, a quantum-safe connection has already been established. Use the client to send the message "shutdown" in order to end the execution of the server.
