File Processor Project

Overview

The File Processor Project is a web application that accepts a text file, compresses its contents using the Huffman coding algorithm, and encrypts the compressed data using AES encryption. This project demonstrates the integration of a Spring Boot backend with a React frontend to handle file uploads and processing.

Technologies Used

• Spring Boot: For creating the backend REST API.
• React: For building the user interface.
• Huffman Coding: For compressing the text data.
• AES Encryption: For encrypting the compressed data.

Setup Instructions

Prerequisites

1. Java 17 or above
2. Maven (for building the Spring Boot application)
3. Node.js and npm (for the React frontend)

Backend Setup

1. Clone the Repository:

   git clone https://github.com/Maniac198/ZipCrypt.git
   cd https://github.com/Maniac198/ZipCrypt.git

2. Navigate to the Backend Directory:

   cd backend

3. Build and Run the Spring Boot Application:

   ./mvnw spring-boot:run

   The application will start on http://localhost:8080.

Frontend Setup

1. Navigate to the Frontend Directory:

   cd frontend

2. Install Dependencies:

   npm install

3. Run the React Application:

   npm start

   The application will be available at http://localhost:5173.

API Endpoints

Compress and Encrypt File

• URL: http://localhost:8080/api/compress-encrypt
• Method: POST
• Request Type: multipart/form-data
• Form Data:
  • file: The text file to be processed.

Example Response

{
    "original": "Hello, this is a test file!",
    "compressed": "110101010...",
    "encrypted": "U2FsdGVkX19KSmFsaM..."
}

Testing with Postman

1. Open Postman and create a new POST request.
2. Use the URL: http://localhost:8080/api/compress-encrypt.
3. In the Body tab, select form-data.
4. Set the key to file and choose your text file.
5. Click Send and check the response.

Conclusion

This project demonstrates the use of modern web technologies to perform file processing tasks. The integration of Spring Boot and React provides a solid foundation for building web applications.
