    Implementation for a simple order-preserving encryption scheme. · 3a45f6ff

    This is meant for use when encrypting the current time within the
    period in order to get a monotonically increasing revision counter
    without actually revealing our view of the time.
    This scheme is far from the most state-of-the-art: don't use it for
    anything else without careful analysis by somebody much smarter than
    I am.
    See ticket #25552 for some rationale for this logic.
