## 📦 Installation

### PyPI Installation (Recommended)

```bash
# Install latest stable version
pip install cryptopix

# Install with optional GPU acceleration
pip install cryptopix[gpu]

# Install development version with all extras
pip install cryptopix[dev,gpu,docs]
```

### From Source

```bash
git clone https://github.com/cryptopix-official/cryptopix.git
cd cryptopix
pip install -e .
```

## 🏁 Quick Start

### Key Encapsulation Mechanism (KEM)

```python
import cryptopix

# Create KEM instance with 128-bit post-quantum security
kem = cryptopix.create_kem(128)

# Generate key pair
public_key, private_key = kem.keygen()

# Encapsulate shared secret
shared_secret, capsule = kem.encapsulate(public_key)

# Decapsulate shared secret
recovered_secret = kem.decapsulate(private_key, capsule)

print(f"✓ Secure key exchange completed: {len(shared_secret)} bytes")
```

### Digital Signatures

```python
import cryptopix

# Create signature scheme
sign_scheme = cryptopix.create_signature_scheme(128)
key_pair = sign_scheme.keygen()

# Sign message
message = b"Hello, Post-Quantum World!"
signature = sign_scheme.sign(message, key_pair)

# Verify signature
is_valid = sign_scheme.verify(message, signature, key_pair)
print(f"✓ Signature valid: {is_valid}")
```

### Color Cipher with Visual Steganography

```python
import cryptopix

# Create color cipher
cipher = cryptopix.create_color_cipher()

# Encrypt with visual steganography
message = "Top secret quantum-resistant data"
encrypted_colors = cipher.encrypt_to_colors(message, key="secure_key")

# Decrypt from colors
decrypted_message = cipher.decrypt_from_colors(encrypted_colors, key="secure_key")
print(f"✓ Steganographic encryption: {decrypted_message}")
```

### Quantum-Resistant Hashing

```python
import cryptopix

# Create color hash instance
hasher = cryptopix.create_color_hash()

# Generate quantum-resistant hash
data = b"Important data to hash"
color_hash = hasher.hash(data)

print(f"✓ Quantum-resistant hash: {color_hash.hex()[:32]}...")
```

## 🛡️ Security Levels

CryptoPIX provides multiple security levels to meet different requirements:

| Security Level | Lattice Dimension | Quantum Security | Classical Security |
