Sooo this. The fact that GPUs can do this is kind of trippy but at the same time, I do find it a bit interesting.

It still bothers me when I run into a website that requires a password not to EXCEED 10-12 characters in length.
AMD, I give up.

If my password is password I'm sure I'll be safe.

or websites could start using a password hashing function that doesn't suck.

MD5 is broken.

SHA isn't suited for password hashing at all.

Decent length password + individual salt + bcrypt.

actually it's 1/62^18.

assuming just letters and numbers.

also assuming it knows password length.

if not hen I guess 1/(62+62^2+62^3+...62^n) where n is the maximum length it's guessing.

The limit as N approaches infinity?

News? More like many years old news...

Amazon's EC2 service makes it quite easy to use GPU supercomputing power to crack passwords.
John the Ripper has been mainstream for quite awhile as well.
