These are MAX times.
Hence why "up to" was intentionally included in the very post you quoted and responded to. You're arguing a best-case scenario with a worse-case scenario. Even if we don't average to half but go for the extreme example of 10 times the computing power or 10 times the luck, we're still talking just shy of 5,000 years. Even with 10 times the computational power and
10 times the luck, it would take them up to 500 years.
No matter how you want to look at the math, adding to the 8-digit potential passwords mentioned in the OP makes the solve time go up exponentially and very sharply so.edit
For a little more perspective, think about this.
Odds of getting killed by lighting
in your lifetime - 2,650,000:1
Odds of you winning the lottery
- anywhere between 18,000,000:1 and 120,000,000:1
Odds of guessing a random, 12-digit password
using uppercase, lowercase, numerals, and special characters or anywhere remotely close to it -66,631,762,164,108,958,342,448,140,502,408,732,626,873:1That's over 66 thousand trillian trillian trillian to one.
If you think it's likely anyone will start a brute force anywhere close to such a password, then you must feel damn lucky / borderline blessed every time you walk outside while it's cloudy.
For people who didn't read the post he was responding to, it would take this 25-GPU cluster over 49,000 years to go through all possible combinations in this scenario. We go from less than 6 hours to 49,000 years just by adding 4 digits. Yes, the password being at the very end of all possibilities brute-forced isn't likely, but, when we're talking about lengths of time of this magnitude, it really doesn't matter.Edited by Kaldari - 12/10/12 at 5:07pm
