README

The way simple_handshake_chaining.py operates is illustrated in the following image.

---

Requirements

• python-3.7 (perhaps with 3.8 would work as well);
• docker-compose.

---

Building instructions

pip install -r requirements.txt ./start_up.sh # starts the RabbitMQ broker

Open a new terminal and run:

python ttd.py # runs the Trusted Third Party

Run alice.py and bob.py in two different terminals.

python alice.py python bob.py

You can observe the message exchange executed over RabbitMQ, with the AMQP protocol.

Alice and bob scripts provide with a very basic CLI for sending/receiving messages to each other. ttd.py shows the logs of the Trusted Third Party.
