cd password_manager
cargo build --release
./target/release/password_manager --help
```

## 🚀 Quick Start

```bash
# Create a new database
password_manager create my_passwords.db

# Add a credential
password_manager add credential

# List all items
password_manager list

# Search for items
password_manager search "gmail"

# Generate a password
password_manager generate --length 20 --uppercase --lowercase --numbers --symbols
```

## 🔐 Security Features

- **AES-256-GCM**: Standard encryption
- **ChaCha20-Poly1305**: High security encryption
- **Quantum-resistant**: Multi-layer encryption for future-proof security
- **Hardware acceleration**: Apple Silicon and Intel AES-NI support
- **Argon2id**: Secure key derivation
- **CRC32/SHA-256**: Data integrity verification

## 🧪 Hardware Acceleration

The password manager automatically detects and uses hardware acceleration:

- **Apple Silicon**: ARM AES acceleration
- **Intel**: AES-NI instructions
- **Cross-platform**: Fallback to software implementation

Check hardware support:
```bash
password_manager hardware
```

## 📊 Performance

- **Encryption**: Hardware-accelerated AES operations
- **Key derivation**: Optimized Argon2id parameters
- **Progress tracking**: Real-time operation feedback
- **Multi-threading**: Parallel processing for quantum encryption

## 🔧 Configuration

### Security Levels
- **Standard**: AES-256-GCM (fast, secure)
- **High**: AES + ChaCha20 (very secure)
- **Quantum**: Multi-layer with quantum rounds (maximum security)

### Testing Mode
For development and testing, use reduced security parameters:
```bash
# Demo with testing mode
password_manager demo
```

## 🐛 Known Issues

- Long-running quantum encryption on older hardware
- Progress indicators may not update smoothly on all terminals

## 🔄 Migration

### From Previous Versions
- Database format is backward compatible
- No migration required for existing databases
- New features are opt-in
