Let's see, 9x1059 combinations, If I guess 100,000,000 combinations per sec ( = 108 combinations per sec) it would only take about 9x1051 seconds.
Hmmm... 60 sec per minute x 60 min per hr x 24 hr per day x 365 days per year = 31,536,000 seconds per year. ( = approx 3x107 sec/yr)
9x1051 seconds / (3x107 seconds per year) = 3x1044 years.
uh oh, I'll need to speed thing up a bit.
To try all combinations in 30 years, I need to check 9x1059 / (30 years x 3x107 sec/yr) = 1051 combinations per sec for 30 years.
Yikes!
