A Java desktop application for securely backing up files and directories. It compresses your data into ZIP archives and encrypts them using AES, keeping your backups safe at rest.

• Compress individual files or entire directory trees into ZIP archives
• AES encryption and decryption of files and directories
• Swing-based GUI for easy file selection and operation management
• Encryption key loaded securely from an environment variable — never hardcoded

• Java 8 or higher
• NetBeans IDE (recommended) or any Java-compatible build tool
• An AES secret key stored as a Base64-encoded environment variable

1. Generate a Base64-encoded AES-128 or AES-256 key and set it as an environment variable:

   • On Linux/macOS: export ENCRYPTION_KEY=your_base64_key_here
   • On Windows: set ENCRYPTION_KEY=your_base64_key_here

2. Open the project in NetBeans or compile the source files in the src/ directory manually.

3. Run the Driver class as the entry point.

• src/Driver.java — Entry point; recovers the AES key from the environment and launches the GUI
• src/Landing.java — Main landing window of the application
• src/Compressor.java — Handles ZIP compression of files and directories
• src/Decompressor.java — Handles ZIP decompression
• src/Encryption.java — AES encryption for files and directories
• src/View_FrameOne.java — Primary GUI frame
• src/openHnd.java — File open action handler
• src/selectorHnd.java — File selection handler
• nbproject/ — NetBeans project configuration
• build.xml — Ant build file

• The encryption key is never stored in the codebase. It must be provided via the ENCRYPTION_KEY environment variable at runtime.
• Backups are written to a local Files/Backups/ directory, which is excluded from version control via .gitignore.
