On this occasion, I did not set out to insult you. I set out to suggest an explanation for why cooler and grayer heads than mine are not falling over themselves to merge your designs into the mainline kernel. Did I succeed?
I just shown a problem in jenkins hash - it is not how to find a differnet input for the same output - it is a _law_ which allows to break a hash. You will add some constant, and that law will be turned into something different (getting into account what was written, it will end up with the same law).
Correct. That's called a "weak hash", and Jenkins is known to be a thoroughly weak hash. That's why you never, ever use it without a salt, and you don't let an attacker inspect the hash output either.
Using jenkins hash is equal to the situation, when part of you hash chains will be 5 times longer than median square value, with XOR one there is no such distribution.
Show us the numbers. Salt properly this time to reduce the artifacts that come of applying a weak hash to a poor PRNG, and histogram your results. If you don't get a Poisson distribution you probably don't know how to use gnuplot either. :-)
Added somthing into permutations will not endup in different distribution, since it is permutations which are broken, not its result (which can be xored with something).
I can't parse this. Care to try again? Cheers, - Michael - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
