Of course not. Your defined set of characters didn't have a zero in it. > I'm attempting to generate all possible .onion addressess which look like " > kpvz7ki2v5agwt35.onion" for instance. > "Look like" is pretty vague. To me, 2222222222222222.onion certainly looks like the one you said.

The world doesn't have enough disk space to store *every* address. If you need to calculate all of them, you don't have enough time. You need to rethink whatever your real problem is. For example, if you were really trying to crack a safe with 32 numbers on the dial and 16 settings to open it, perhaps you should forget all of it and get some nitro. Or a stethoscope. Or bribe somebody who knows the combination. If you have to try all of the combinations systematically, you'll never get there. > Again, any input is useful. > > Scott > -- DaveA _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
