Modern Encryption Tool

A secure file encryption and decryption utility with a modern UI that uses industry-standard AES-256 encryption to protect your sensitive files.

Features

• Strong Encryption: Uses AES-256 encryption in GCM mode for maximum security
• Secure Key Derivation: Implements PBKDF2 with 65,536 iterations for secure password-based key generation
• Modern UI: Clean, intuitive interface with responsive design
• Dual Interface: Use either the GUI or command-line interface
• Cross-Platform: Works on Windows, macOS, and Linux
• File Type Support: Works with any file type and size

Requirements

• Java Development Kit (JDK) 8 or higher
• Node.js and npm (for the web interface)

Installation

Option 1: Clone from GitHub

# Clone the repository
git clone https://github.com/yourusername/modern-encryption-tool.git

# Navigate to the project directory
cd modern-encryption-tool

# Install dependencies
npm install

Option 2: Download Release

1. Download the latest release from the Releases page
2. Extract the ZIP file to your preferred location
3. Run the installation script (if applicable)

Usage

Web Interface

1. Start the server:

   npm start

2. Open your browser and navigate to http://localhost:3000
3. Select a file, enter a password, and click either "Encrypt" or "Decrypt"

Java GUI

1. Run the application:

   java EncryptionTool

2. Use the file browser to select a file
3. Enter your password
4. Click "Encrypt" or "Decrypt" as needed

Command Line

# For encryption
java EncryptionTool encrypt <file_path> <password>

# For decryption
java EncryptionTool decrypt <file_path> <password>

Security Considerations

• Password Strength: Use strong, unique passwords for each file you encrypt
• Password Storage: This tool does not store your passwords; you must remember them
• No Recovery: There is no way to recover encrypted files if you forget the password
• Data Integrity: The GCM mode provides authentication to verify data hasn't been tampered with

How It Works

This tool uses a Java backend with AES encryption to securely encrypt and decrypt your files. The password you provide is used to generate a secure encryption key through PBKDF2 key derivation function with a random salt. Your files never leave your computer during the encryption process.
