Passwords Secure? Think Again

Everyone likes to think that their passwords are uncrackable. However, if programs like "ighashgpu", a free password cracking tool, are any indication, all your passwords might be just about as useful as an ice cube in the Arctic. Ighashgpu uses a computer's GPU instead of its CPU to run password guesses. While this may seem unimportant, GPUs have been shown to crack passwords at mind boggling speeds compared to a standard CPU. Even long passwords involving upper and lowercase letters as well as symbols quickly fall victim to the too when running GPU guesses. Still, that's not even the scary part. Your most well thought out passwords could become worthless against even a low-end GPU. For the exact numbers, check here. You may find yourself more than a little surprised and a lot more conscious of how vulnerable you really are.

Hmm, scary, but i hate to disappoint you, but if you'd done your research you would know this: Its been out since about Q1 2009. And has not been updated since the end of that year. All you are doing is bringing it to the attention of potential users thus making the situation worse.

If you had done your research you would know that the main site hasn't been updated, but the program itself has. It's up to version 0.91 right now.

And this is also why you should use strong methods of encrypting password. I.e. SHA-512 + large changing salts and run it multiple times on top of it self. Makes brute forcing slow.

I just downloaded the latest version and got 1.2 billion hashes per second on my GTX 460.

What is this now, some GPU Benchmarking tool? oh wait.. :P

Surely only certain things can be subject to brute force attacks? something like steam or gmail would never allow 3Bn password attempts per second
