Hi Eduardo, You could place a random 4 digit number before and after the target value to confuse people.. i.e. actual price is 24 use the number 2314244334 to hide it, or some other scheme.

In this game, if you guess the price of an item, you win that item. One guess per employee per day. The price of the item is stored in a DB. A DB a lot of people have access to. This number should be crypted, but then, its an encrypted number. Brute forcing your way to the number should be VERY simple. A simple for() loop testing all the numbers between 0 and 1000 and you are all set. Is there a way to keep this number COMPLETELY private so that only the guy that posted it knows it ? Or even better, a number that NO ONE knows ? My only guess is enforcing this number thru unix permissions, but then, the number in its encrypted form has to be read at least once to be compared. You can write down this number and test. How can we solve this ? _________________________________________________________ Do You Yahoo!?
