Here's an example implementation in Python:
def validate_activation_code(activation_code, license_details, hardware_config): # Extract the activation code components license_type = activation_code[:5] encrypted_hardware = activation_code[5:15] checksum = activation_code[15:20] expiration_date_code = activation_code[20:]
# Generate the checksum checksum = hmac.new(license_type.encode(), encrypted_hardware.encode(), hashlib.sha256).hexdigest()[:5]
# Validate the checksum expected_checksum = hmac.new(license_type.encode(), encrypted_hardware.encode(), hashlib.sha256).hexdigest()[:5] if checksum != expected_checksum: return False
