Was Your Linkedin Password Hacked?

The recent news that 6 million passwords had been stolen from Linkedin has a lot people understandably concerned. This tool will allow you to check if yours is among those at risk.


Wait a Minute, Why Is This Tool Safe?

You already changed your password, right? You no longer use that old password anywhere else, right? If not please make sure you do that first. The above tool asks you to enter your LinkedIn password, and then computes its SHA-1 hash and sends the result to LastPass.com to search the list of 6.5 million leaked password hashes. A hash is a mathematical function that is simple to perform in one direction, but very difficult to reverse. Meaning, the tool will convert your password into a series of characters in such a way that it will be very difficult to re-construct your original password.

Only the hash of your password will be sent to LastPass.com’s servers, not your actual password. This hash will not be stored or logged at all. Please view source the page if you’re technically inclined.

Note that if you used a simple password, such as one based on dictionary words, then it might be possible to reconstruct your original password. This is what all of the concern is about: the hashes of simple passwords can be easily reconstructed to reveal the original actual password.
