# Cryptographic Vulnerability Predictor

## Overview
This project provides a system to predict vulnerabilities in blockchain hashes and ECC keys based on machine learning.

## Setup

1. Clone the repository.
   ```bash
   git clone https://github.com/DeadmanXXXII/BlockEEC.git

2. Backend Setup:

Navigate to the backend directory.

Install dependencies:

pip install -r requirements.txt

Run the Flask app:

python app.py



3. Frontend Setup:

Navigate to the frontend directory.

Install dependencies:

npm install

Run the React app:

npm start



4. Training the Model:

Run the train_model.py script to train the model using the data in the data directory.

The trained model will be saved as backend/model_v2.pkl.




Usage

1. Send POST requests to /predict_blockchain or /predict_ecc with the appropriate cryptographic data.


2. The API will return a prediction on whether the input is vulnerable.

This structure includes secure APIs, feature extraction, real-time predictions, and front-end integration, making it a scalable, secure, and user-friendly system.
