/**
 * The default encryption module simply passes through the decrypt and encrypt text.
 * A real implementation should adhere to PCI compliance, which requires robust key
 * management, including regular key rotation. An excellent solution would be a module
 * for interacting with the StrongKey solution. Refer to this discussion:
