If you depend on a secret for your security, what do you do when the secret is discovered? If it is easy to change, like a cryptographic key, you do so. If it’s hard to change, like a cryptographic system or an operating system, you’re stuck. You will be vulnerable until you invest the time and money to design another system. — Whitfield Diffie
