Test the strength of your passwords with “How Big is Your Haystack?”

There are password strength checkers all over the Web, but there is only one that tests your passwords as brutally as this one. How Big is Your Haystack will test your passwords against three different kinds of attack scenarios and give you an estimate of the time it would take to crack your passwords. We tested ours and most were in the billions of years for two attack scenarios – and around 2 years when pitted against a massive cracking array using one hundred trillion guesses per second.

Here’s what the site’s developers have to say:

“Every password you use can be thought of as a needle hiding in a haystack. After all searches of common passwords and dictionaries have failed, an attacker must resort to a “brute force” search – ultimately trying every possible combination of letters, numbers and then symbols until the combination you chose, is discovered.

If every possible password is tried, sooner or later yours will be found. The question is: Will that be too soon . . . or enough later?

This interactive brute force search space calculator allows you to experiment with password length and composition to develop an accurate and quantified sense for the safety of using passwords that can only be found through exhaustive search…”.
