Qryptian

Qryptian is a comprehensive project that ensures that you do not leak any sensitive data when interacting with Large Language Models(LLMs) on chat interfaces. It combines a Chrome extension for capturing user messages and a backend service for redacting sensitive information. Both of these can be deployed locally and used for redaction straightaway.

Project Structure

The project consists of two main components:

1. qr-extension: A Chrome extension for capturing and streaming user messages.
2. qr-redactor: A backend service for identifying and redacting sensitive data.

qr-extension

The Chrome extension is responsible for capturing user messages from web pages and streaming them to the background script.

Key files:

• public/content.js: Content script that runs on web pages
• public/manifest.json: Extension manifest file
• src/: Source TypeScript files

qr-redactor

The backend service processes the captured messages, identifies sensitive information, and performs redaction.

Key files:

• app/main.py: FastAPI application entry point
• app/model.py: Sensitive data identification model
• app/redactor.py: Text redaction logic
• Dockerfile: Container configuration for the backend service

Installation

1. Clone this repository:

   git clone https://github.com/vaibs-d/qryptian.git
   

2. Set up the Chrome extension:

   • Navigate to chrome://extensions/ in Chrome
   • Enable "Developer mode"
   • Click "Load unpacked" and select the qr-extension/public directory

3. Set up the backend service:

   • Navigate to the qr-redactor directory
   • Build and run the Docker container:

     docker build -t qr-redactor .
     docker run -p 8000:8000 qr-redactor
     

Usage

1. Use the Chrome extension to capture and stream user messages from web pages.
2. The backend service will process the streamed messages, identify sensitive information, and perform redaction.

Development

• For the Chrome extension, modify the TypeScript files in qr-extension/src/, then compile them to JavaScript.
• For the backend service, modify the Python files in qr-redactor/app/.
