#define EXPIRE_KEYS_TIMEOUT_SECONDS   (NEW_KEY_TIMEOUT_SECONDS + (60*2))

The time after which we drop a key from the secrets file.

The EXPIRE_KEYS_TIMEOUT_SECONDS - NEW_KEY_TIMEOUT_SECONDS is the minimum time window a client has to complete authentication.

#define NEW_KEY_TIMEOUT_SECONDS   (60*5)

The maximum age of a key before we create a new key to use in challenges.

This isn't super-reliably enforced, since system clocks can change or be wrong, but we make a best effort to only use keys for a short time.
