secure-communication

Secure P2P communication, via public key exchange and multiple cyphers.

Background

This project is our BMA and a collaboartion betwean andrashorber and me. The program is executed on the pocket calculators that we already need for class at our School, the TI-Nspire CX CAS. The programming language we will use is what the TI-Nspire supports, i.e. python 3.4.0.

Installation

1. clone the repo
2. install dependencies pip install -r requirements.txt

For development

1. create a virtual environment python -m venv .venv
2. activate the virtual environment

• Windows: .venv\Scripts\activate
• Linux: source ./.venv/bin/activate

To deactivate the venv type deactivate

3. update pip python -m pip install --upgrade pip
4. install the dev dependencies pip install -r requirements-dev.txt
5. add the env variables to your environment export $(xargs < .env)

Optional

1. Use pyenv to manage your python versions

Help

If you can't install Python version 3.4.0 you probably need to install a older version of libssl. This isssue is currently tracked in here.

Known Issues

• Because this is a MicroPython implementation, it doesn't have a true source of random, like random.SystemRandom().
