A non-deterministic hash function wouldn't be terribly useful, would it? ;-)

Great question that shows why salting your hashes is so important.

Thanks,

That's what I was thinking... I had to harken back to Advanced Concepts in C... at least it was considered advanced concepts in C 14 years ago.... these days this is probably beginners stuff (Hashes and the like)....

Aaah age.... where'd I put my walker?

Why not? I can think of at least one use for one.

In the old days the apprentice engineer was sent to fetch a bucketful of holes, more recently people were asked to design a device driver for the GSD, and today we could assign the task of producing an effective access control system using an indeterminate hash - the victimtrainee would have exactly the same chance of carrying out this task as anyone did with the traditional spoof tasks.
