```

### Image-Based Encryption (Steganography Mode)

```python
from cryptopix import CryptoPix
from PIL import Image

# Initialize
cp = CryptoPix()

# Encrypt text to image (1-17ms)
image_data, smart_key = cp.encrypt("Hello, World!", "my_password")

# Save encrypted image
with open("encrypted.webp", "wb") as f:
    f.write(image_data.getvalue())

# Decrypt image back to text
image = Image.open("encrypted.webp")
result = cp.decrypt(image, smart_key, "my_password")
print(result['content'])  # "Hello, World!"
```

### Ultra-Fast Raw Encryption (Speed Mode)

```python
from cryptopix import CryptoPix

# Initialize
cp = CryptoPix()

# Ultra-fast encryption (0.013ms average)
encrypted_data, key_data = cp.encrypt_fast("Hello, World!", "my_password")

# Save encrypted data
with open("encrypted.dat", "wb") as f:
    f.write(encrypted_data)

# Ultra-fast decryption
decrypted_text = cp.decrypt_fast(encrypted_data, key_data, "my_password")
print(decrypted_text)  # "Hello, World!"
```

### Performance Comparison

```python
import time
from cryptopix import CryptoPix

cp = CryptoPix()
text = "Performance test data"
password = "test123"

# Image mode timing
start = time.perf_counter()
img_data, smart_key = cp.encrypt(text, password)
img_time = (time.perf_counter() - start) * 1000

# Fast mode timing  
start = time.perf_counter()
raw_data, key_data = cp.encrypt_fast(text, password)
fast_time = (time.perf_counter() - start) * 1000

print(f"Image mode: {img_time:.2f}ms")
print(f"Fast mode: {fast_time:.3f}ms")
print(f"Speed improvement: {img_time/fast_time:.0f}x faster")
```

### Convenience Functions

```python
# Image-based convenience functions
from cryptopix import encrypt_text, decrypt_image
from PIL import Image

image_data, smart_key = encrypt_text("Secret message", "password123")
image = Image.open("encrypted.webp")
result = decrypt_image(image, smart_key, "password123")

# Ultra-fast convenience functions
from cryptopix import encrypt_fast, decrypt_fast

encrypted_data, key_data = encrypt_fast("Secret message", "password123")
decrypted_text = decrypt_fast(encrypted_data, key_data, "password123")
```

## 📚 Advanced Usage

### Mode Selection Strategy

```python
from cryptopix import CryptoPix

cp = CryptoPix()

def smart_encrypt(data, password, priority="auto"):
    """Choose encryption mode based on requirements"""
    
    if priority == "security":
        # Maximum security with steganography
        return cp.encrypt(data, password)
    elif priority == "speed":
        # Maximum performance
        return cp.encrypt_fast(data, password)
    elif priority == "auto":
        # Automatic selection based on data size
        if len(data) > 10000:  # Large data - use fast mode
            return cp.encrypt_fast(data, password)
        else:  # Small data - use image mode for security
            return cp.encrypt(data, password)
```

### Custom Image Dimensions (Image Mode)

```python
from cryptopix import CryptoPix

cp = CryptoPix()

# Specify custom width for image encryption
image_data, smart_key = cp.encrypt("Long text content", "password", width=100)
```

### Batch Processing (Fast Mode)

```python
import time
from cryptopix import CryptoPix

cp = CryptoPix()

# Process multiple messages rapidly
messages = ["Message 1", "Message 2", "Message 3"] * 1000
password = "batch_password"

start_time = time.perf_counter()

encrypted_batch = []
for msg in messages:
    encrypted_data, key_data = cp.encrypt_fast(msg, password)
    encrypted_batch.append((encrypted_data, key_data))

processing_time = (time.perf_counter() - start_time) * 1000
print(f"Processed {len(messages)} messages in {processing_time:.2f}ms")
print(f"Average per message: {processing_time/len(messages):.4f}ms")
```

### Error Handling for Both Modes

```python
from cryptopix import CryptoPix
from cryptopix.core.exceptions import (
    EncryptionError, 
    DecryptionError, 
    InvalidPasswordError
)

cp = CryptoPix()

# Image mode error handling
try:
    image_data, smart_key = cp.encrypt("text", "password")
except EncryptionError as e:
    print(f"Image encryption failed: {e}")

# Fast mode error handling
try:
    encrypted_data, key_data = cp.encrypt_fast("text", "password")
except EncryptionError as e:
    print(f"Fast encryption failed: {e}")

# Decryption error handling
try:
    result = cp.decrypt_fast(encrypted_data, key_data, "wrong_password")
except InvalidPasswordError:
    print("Incorrect password provided")
except DecryptionError as e:
    print(f"Decryption failed: {e}")
```

### Performance Monitoring

```python
import time
from cryptopix import CryptoPix

def benchmark_modes(text, password, trials=100):
    """Compare performance between modes"""
    cp = CryptoPix()
    
    # Benchmark image mode
    img_times = []
    for _ in range(trials):
        start = time.perf_counter()
        img_data, smart_key = cp.encrypt(text, password)
        img_times.append((time.perf_counter() - start) * 1000)
    
    # Benchmark fast mode
    fast_times = []
    for _ in range(trials):
        start = time.perf_counter()
        raw_data, key_data = cp.encrypt_fast(text, password)
        fast_times.append((time.perf_counter() - start) * 1000)
    
    img_avg = sum(img_times) / len(img_times)
    fast_avg = sum(fast_times) / len(fast_times)
    
    return {
        'image_mode': {
            'avg_ms': img_avg,
            'min_ms': min(img_times),
            'max_ms': max(img_times)
        },
        'fast_mode': {
            'avg_ms': fast_avg,
            'min_ms': min(fast_times),
            'max_ms': max(fast_times)
        },
        'speed_improvement': img_avg / fast_avg
    }
```
