File Hiding Application

Description

The File Hiding Application is a secure Java-based project built with Maven and MySQL. This application allows users to:

1. Hide Files: Securely copy file data to a MySQL database and delete the original file.
2. View Hidden Files: View a list of all hidden files stored in the database.
3. Unhide Files: Restore hidden files back to their original location.

The application uses OTP-based authentication powered by the JavaMail API and Google App Passwords to ensure secure email delivery for signup and login.

Features

• Secure User Authentication: Login/signup using OTPs sent to the user's email.
• File Hiding: Store file content securely in the database and remove the original file.
• View Hidden Files: Display the list of hidden files.
• Unhide Files: Restore hidden files back to their original locations.
• JavaMail API Integration: Secure email delivery via Gmail App Passwords.
• Maven Integration: Use Maven for dependency and build management.

Tech Stack

• Java: Core programming language.
• Maven: Project and dependency management.
• MySQL: Database for user and file data storage.
• JavaMail API: Sending OTPs securely.
• Google App Passwords: Secure email authentication.

Prerequisites

Before setting up the project, ensure you have the following installed:

• Java Development Kit (JDK): Version 15 or above.
• Maven: To manage project dependencies.
• MySQL: Database server.
• Gmail Account: To send OTPs using App Passwords (turn on 2-Step Verification).

Installation

Follow these steps to set up and run the File Hiding Application:

1. Clone the Repository

git clone https://github.com/bhavyaLalchandani/File_Hiding_Application.git
cd File_Hiding_Application

2. Set Up MySQL Database

• Open MySQL and create a new database and tables using the below code:

CREATE DATABASE filehider;

USE filehider;

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100),
    email VARCHAR(100) UNIQUE
);

CREATE TABLE data (
    id INT AUTO_INCREMENT PRIMARY KEY,
    file_name VARCHAR(100),
    path VARCHAR(255),
    email VARCHAR(100),
    bin_data BLOB
);

• Update the database connection details in MyConnection.java:

  • Replace your-username and your-password with your MySQL credentials.

Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/filehider", "your-username", "your-password");

3. Configure Gmail for OTP Delivery

• Enable 2-Step Verification in your Gmail account.
• Generate an App Password from Google Account -> Security -> App Passwords.
• Update the SendOTPService.java file with your email and generated app password:
• Replace [email protected] and your-app-password with your Gmail address and generated App Password.

return new PasswordAuthentication("[email protected]", "your-app-password");

4. Add Required Maven Dependencies

Ensure the following dependencies are added to your pom.xml file to include JDBC Driver and JavaMail API:

• MySQL JDBC Driver: Add the following dependency to your pom.xml:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.32</version>
</dependency>

• JavaMail API: Add the following dependency to your pom.xml:

<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.2</version>
</dependency>

• For more details on these dependencies:
