Show HN: How secure is your passphrase?

Though if you can use a less common language than English, you might get an even better passphrase. I know the Passphrase FAQ says using another language doesn't make your passphrase harder to guess[0], but having worked a bit with language tech, I'm pretty sure that's only true under certain "ideal conditions". Most lang. tech is extremely English-focused, if there's a new development, it always happens with English first. In non-English languages, OTOH, it can be a challenge simply to find a good dictionary, and finding the corpora to do the kind of rating done by lsb's algorithm is even harder.

Of course, if the "other language" is French/German/Spanish, sure, it's probably not much safer. But if you're lucky enough to know a more marginalised language, I'd say go with it.

Yup: the assumption is that it won't even semantically parse. The only way that "correct horse battery staple" even makes sense is with an image and a story!

Much as passwords work on the lexical level, and adding random punctuation ensures it's not a dictionary word, breaking syntax and semantics is the analogue for passphrases.

Ah, but it's all local, with something like a compressed bloom filter doing lookups. So nothing goes across the wire!

Hm. I've got "It's". Will investigate.
