8-Character Passwords Not Secure

From article on CNN.com.  Not GIS news but something that could affect all of us…

Researchers made their own “supercomputers” using off-the-shelf graphics cards processors to show that computing power is capable of cracking passwords in short time frames.

“The researchers used clusters of graphics cards to crack eight-character passwords in less than two hours.” (emphasis added)

… “They assumed a sophisticated hacker might be able to try 1 trillion password combinations per second. In that scenario, it takes 180 years to crack an 11-character password, but there’s a big jump when you add just one more character — 17,134 years.”
