I'd pick an odd number so the low bit always changes, and a constant with about half the bits set, maybe 24 < n < 40 or some such. I'm not certain either of those is strictly required but I'd do them anyway. -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
