HW4 for gensec

This application is a Langchain agent which intends to be helpful at de-obfuscating and de-minifying javascript code. On the web, minifying javascript code is common to minimize javascript source file size before they are sent over the network to the client. Obsfuscating is also used to limit the ability to reverse engineer the function of javascript running on the client from enterprise web applications. The application is programmed to ingest javascript source files both from the local machine, as well as from URLs.

Setup + Run

Install python3, then

cd hw4
pip install -r requirnments.txt
cp .env.example .env #fill in env file with key
python3 app.py
