🏁 Quick Start

Basic Text Encryption

from clwe import ColorCipher

# Initialize cipher
cipher = ColorCipher()

# Encrypt text
message = "Hello, CLWE!"
password = "my_secret_password"
encrypted = cipher.encrypt(message, password)

# Decrypt text
decrypted = cipher.decrypt(encrypted, password)
print(decrypted)  # "Hello, CLWE!"

Key Encapsulation Mechanism (KEM)

from clwe import ChromaCryptKEM

# Initialize KEM
kem = ChromaCryptKEM("Min")  # 815+ bit security

# Generate key pair
public_key, private_key = kem.keygen()

# Encapsulate shared secret
shared_secret, ciphertext = kem.encapsulate(public_key)

# Decapsulate (receiver side)
recovered_secret = kem.decapsulate(private_key, ciphertext)
assert shared_secret == recovered_secret

Digital Signatures

from clwe import ChromaCryptSign

# Initialize signer
signer = ChromaCryptSign("Min")  # 815+ bit security

# Generate signing keys
pub_key, priv_key = signer.keygen()

# Sign message
message = "Important document"
signature = signer.sign(priv_key, message)

# Verify signature
is_valid = signer.verify(pub_key, message, signature)
print(is_valid)  # True

Color Hashing

from clwe import ColorHash

# Initialize hasher
hasher = ColorHash("Min")

# Generate color hash
data = "Hello World"
colors = hasher.hash(data)  # Returns RGB color tuple

# Verify hash
is_valid = hasher.verify(data, colors)
print(is_valid)  # True

📚 Advanced Usage

Visual Steganography

from clwe import ColorCipher

cipher = ColorCipher()

# Encrypt to image (steganography)
with open("secret_document.pdf", "rb") as f:
    data = f.read()

encrypted_image = cipher.encrypt_to_image(data, "password123")

# Save as WebP
with open("encrypted.webp", "wb") as f:
    f.write(encrypted_image)

# Decrypt from image
with open("encrypted.webp", "rb") as f:
    image_data = f.read()

decrypted_data = cipher.decrypt_from_image(image_data, "password123")

File Encryption

from clwe import ColorCipher

cipher = ColorCipher()

# Encrypt file
encrypted = cipher.encrypt_to_image("large_file.zip", "password123")

# Decrypt to specific directory
decrypted_path = cipher.decrypt_from_image(encrypted, "password123", "/output/dir")

Batch Operations

from clwe import ColorCipher
import os

cipher = ColorCipher()

# Encrypt multiple files
files = ["doc1.pdf", "doc2.docx", "image.jpg"]
encrypted_files = []

for file_path in files:
    encrypted = cipher.encrypt_to_image(file_path, "batch_password")
    encrypted_files.append(encrypted)

# Decrypt all files
for i, encrypted in enumerate(encrypted_files):
    output_path = cipher.decrypt_from_image(encrypted, "batch_password", "/output")
    print(f"Decrypted: {output_path}")

Deterministic Encryption (SOP Mode)

from clwe import ColorCipher

cipher = ColorCipher()

# Standard encryption (variable output for security)
encrypted1 = cipher.encrypt_to_image("message", "password")
encrypted2 = cipher.encrypt_to_image("message", "password")
print(encrypted1 == encrypted2)  # False (different outputs)

# Deterministic encryption (SOP mode)
encrypted3 = cipher.encrypt_to_image("message", "password", mode="SOP")
encrypted4 = cipher.encrypt_to_image("message", "password", mode="SOP")
print(encrypted3 == encrypted4)  # True (identical outputs)

# Perfect for testing, reproducible builds, and deterministic protocols

Hardware Acceleration

from clwe import ChromaCryptKEM

# Use GPU acceleration if available
kem = ChromaCryptKEM("Min", hardware_acceleration=True)

# Automatic hardware detection and optimization
public_key, private_key = kem.keygen()  # Uses GPU if available

🔧 Configuration Options

Security Levels

from clwe import ChromaCryptKEM, ChromaCryptSign

# Available security levels
kem_min = ChromaCryptKEM("Min")    # 815+ bits
kem_bal = ChromaCryptKEM("Bal")    # 969+ bits
kem_max = ChromaCryptKEM("Max")    # 1221+ bits

signer_min = ChromaCryptSign("Min")    # 815+ bits
signer_bal = ChromaCryptSign("Bal")    # 969+ bits
signer_max = ChromaCryptSign("Max")    # 1221+ bits

Performance Optimization

from clwe import ChromaCryptKEM, ColorCipher

# Enable all optimizations
kem = ChromaCryptKEM("Min", optimized=True, hardware_acceleration=True)

# Memory-efficient mode
cipher = ColorCipher(memory_efficient=True)

# Streaming mode for large files
encrypted = cipher.encrypt_large_file("huge_file.zip", "password")
