Why they need to use a random number instead of fixed defined number? You could use either. You just try to make sure that by XOR'ing a whole lot together you don't end up with one of the originals. That why we like to use random number generators with a large average and minimum hamming distance, so we can be sure the above has a very slim chance of happening. You could construct a fixed sequence too, but that would be more work than to just rely on the ramdom number generator. >2. Is there any possible that the collision will occur? Yes. How probable depends on the size of the keys. -- GCP
