for website brainwallet.org is closed permanently, but for brainwallet.io is still open and can be accessed.
brainwallet.org closed down after someone at defcon announced the release of a 'brainwallet cracker'. To me it's closing was symbolic though, such wallets are as seemingly as secure as they were before the release.
I'd love to see how these are cracked. You can have one word or a hundred. There are millions of words. You can do it in English or another language. You can do it literally or phonetically. There are gazillions of possibilities. It should be harder to crack a brain wallet (that isn't obvious) than it is a 30-character password (that also isn't obvious).
I prefer using a brainwallet on your local language with different capitalization, symbols and other stuffs. To be able to produce a library of all the possibilities to crack a single brainwallet, you must have terrabytes of data, ranging from the English language to any other language possible. So the release of a brainwallet cracker shouldn't be that much of a problem, given that there are still a lot more ways to produce a genuin brainwallet passphrase without simply relying to the common English words/phrases.
You can also mix it up, using multiple languages, different capitalization, special chars, and both literal and phonetic words. It's impossible to crack. The only ones that would be are those that are obvious. Or the "Horse battery staple..." because that one's been shared for years.
