NightShade is a capture the flag (CTF) framework designed to facilitate the creation and management of cybersecurity competitions. The platform supports multiple CTF formats including jeopardy-style, traditional, and blind-style competitions. The framework provides a web-based interface for contest administration and participant interaction. Users can access challenge pages, view user profiles, and browse available contests through the platform's interface. NightShade is built using Django and includes multi-tenant architecture capabilities, allowing multiple sites to run simultaneously on a single installation. The system requires database setup through Django's migration system and domain configuration for proper request handling. The platform includes features for challenge management, user registration and profiles, contest listing, and scoring systems. It supports educational institutions and non-profit organizations with potential free hosting options. Installation involves setting up Python dependencies, configuring the database schema, and establishing domain settings through Django's management interface. The framework is designed to simplify the process of running cybersecurity competitions for educational and training purposes.
