> It could be more than the number of hydrogen atoms in the universe, or 12. Doesn't matter. You don't really have to look at passwords longer than 256 bits, because above that you'll have guaranteed collisions. (The exact math is a bit more complicated, because there might be so many collisions in the first 256 bits, that there are strings longer than 256 bits that produce hashes that haven't been hit before. But the order of magnitude of 256 bits is about right.) |
