Therefore, it does not rely on large prime numbers, does it? I think maybe you are getting confused with public key systems (such as PGP). Well, a BILLION computers working at once is not quite a legit. crack, but if it can be done by say 1000 pentiums in a month, then a few AS400s or a couple of Crays could probably do it in a few days, then I'd be scared.
