# 🔐 BackupZCrypt
**BackupZCrypt is a simple, powerful tool that helps you protect your sensitive files with military-grade encryption.**
## 📋 What BackupZCrypt Does For You
BackupZCrypt gives you privacy and security in a few simple clicks:
- **🛡️ Protect Sensitive Documents** - Encrypt financial records, personal photos, medical information, and more
- **☁️ Secure Cloud Storage** - Safely store encrypted files on any cloud like Dropbox, Google Drive, or OneDrive
- **🔒 Control Your Privacy** - Keep your data private, even when sharing devices or storage
- **✅ Peace of Mind** - Industry-standard encryption means your files stay private until you decide otherwise
## ❓ Why Choose BackupZCrypt?
- **🖱️ Simple Interface** - No cryptography knowledge needed - just select files, choose a password, and encrypt
- **🤖 Automated Worker** - Run unattended backups and restores as a background service or Docker container
- **🏦 Military-Grade Security** - Uses the same encryption standards trusted by financial institutions
- **🔌 No Internet Required** - Works completely offline, keeping your sensitive data off the network
- **🛠️ Multiple Security Options** - Choose from multiple proven encryption methods to match your needs
- **💯 Completely Free** - Open-source and free to use, forever
## ⭐ Features for Privacy Enthusiasts
* **🔄 Multiple Encryption Algorithms** - AES-256 GCM, ChaCha20-Poly1305, Twofish-256 GCM, Serpent-256 GCM, and Camellia-256 GCM
* **🔑 Multiple Key Derivation Algorithms** - Argon2id, Scrypt, and PBKDF2
* **🗜️ Zstandard Compression** - Three compression presets: Fast (speed-optimized), Normal (balanced, default), and Best (maximum compression)
* **🕵️ Filename Obfuscation** - Hide original file and folder names using GUID, SHA-256, or SHA-512 obfuscation
* **📄 Manifest-Based Architecture** - Encrypted manifest files store all metadata needed for restoration, eliminating per-file headers and simplifying the restore process
* **📊 Password Strength Guidance** - Built-in analyzer evaluates your password and warns you before using a weak one
* **💻 Local Processing Only** - Your files and passwords never leave your computer
* **👁️ Zero Data Collection** - We don't track, collect, or transmit any of your information
## 🚀 Usage
BackupZCrypt offers two execution modes depending on your needs:
### 💻 Terminal (Interactive)
The Terminal mode provides an interactive command-line interface for manual backup and restore operations. Ideal for one-off tasks or when you want full control over each step.
### 🤖 Worker (Automated)
The Worker is a background service that performs **automated, unattended backups and restores**. It runs once, processes any pending operations, and stops automatically — perfect for scheduled tasks, CI/CD pipelines, or containerized environments.
#### How It Works
The worker uses **four directory bindings**:
| Directory | Default Path | Purpose |
|---|---|---|
| **BackupSource** | `/data/backup-source` | Place files here to create an encrypted backup |
| **BackupDestination** | `/data/backup-destination` | Encrypted backup output is written here |
| **RestoreSource** | `/data/restore-source` | Place an encrypted backup here to restore it |
| **RestoreDestination** | `/data/restore-destination` | Restored files are written here |
**On startup**, the worker:
1. Checks `BackupSource` for files → if found, creates/updates an encrypted backup in `BackupDestination`
2. Checks `RestoreSource` for a valid backup (manifest file) → if found, restores it to `RestoreDestination`
3. Optionally deletes source files after each successful operation
4. Stops automatically when there is nothing left to process
#### Environment Variables
All configuration options are available as environment variables:
| Variable | Description | Default |
|---|---|---|
| `BACKUP_PASSWORD` | Password for encryption/decryption | *(empty)* |
| `BACKUP_ENCRYPTION_ALGORITHM` | `None`, `Aes`, `Twofish`, `Serpent`, `ChaCha20`, `Camellia` | `Aes` |
| `BACKUP_KEY_DERIVATION_ALGORITHM` | `Argon2id`, `PBKDF2`, `Scrypt` | `Argon2id` |
| `BACKUP_NAME_OBFUSCATION` | `None`, `Guid`, `Sha256`, `Sha512` | `None` |
| `BACKUP_COMPRESSION` | `None`, `ZstdFast`, `Zstd`, `ZstdBest` | `None` |
| `BACKUP_DELETE_SOURCE_FILES` | Delete source files after operation (`true`/`false`) | `false` |
## 🚀 Roadmap
BackupZCrypt is constantly evolving. Here's what we're planning for future releases:
- **🎨 Enhanced User Interface** - Upcoming UI improvements for better usability and aesthetics
- **⚙️ Advanced Parameter Configuration** - Expert mode allowing customization of encryption parameters for advanced users
- **👥 Community-Driven Development** - We highly value community suggestions and contributions to guide the project's future
We're committed to continuously improving BackupZCrypt based on user feedback and security best practices. Your suggestions are always welcome and will help shape the application's future.

## 🔍 Security Notes
- 🔑 Your security depends on your password strength - use long, complex passwords
- 🔄 Keep your operating system and BackupZCrypt updated
- ⚠️ There is no password recovery. If you forget your password, your encrypted files cannot be decrypted.
