PriCoSha 2.0

A Flask application that allows users to create and share content items among groups of other users, enhanced with cryptographic methods to increase security measures.

How to run

1. Make sure to install needed Python libraries: pip install flask flask_uploads pymysql flask-scrypt flask_kvsession pycryptodome. You also need to install redis separately on your computer, which can be done via brew install redis (Mac), through downloadable zip files for Windows, or Ubuntu.
2. Obtain a self-signed certificate & key (localhost.crt, localhost.key)
3. Dump database schema into a db (name it pricosha) and start your SQL server and redis server via redis-server (for Windows just click the redis-server executable).
4. Run python init.py in command prompt or terminal at the root folder of this project.
5. Should be running at https://localhost:5000!
