Quote - I really hate to break this to you, but todays gpu's, can generate every key possiblilty rather quickly. Over a million per stream processor, per second.

My workstation has 3200 stream processors, do the math.

...

Um, that would be 3200 * 1000000 = 3.210^9 keys per second, or in other words, to guess baggingsbills key (who conveniently only seems to use keys consisting of 32 letters and digits as posted above), you need only 36^32 / 3.210^9 / 2 =~ 10^40 seconds on the average. Sounds much easier than a discouraging "billion years", doesn't it?
