Sep 6	comment	Are there state-of-the-art techniques or theory specifically for attacking passphrases over passwords? Indeed. There could be some tweaks to Markov models expressly to fit this problem. For instance generating longer phrases internally but leaving out small grammatical stopwords. But it's such a large area it would be hard to know where to focus without a resource of leaked/hacked passphrases to see what people really choose in practice.
Aug 24	asked	Are there known hacks or security problems on broadband USB dongles?
Aug 23	comment	Should passwords be truly random? Another perspective would be that a truly random password would be an implementation of a "cryptovariable" (or whatever).

Aug 16	comment	Are there state-of-the-art techniques or theory specifically for attacking passphrases over passwords? Yes there is definitely more scope for making a passphrase difficult to guess for the cases when you get to choose your own passphrase. That doesn't mean that most people won't continue to not do this and therefore have passphrases with rather low entropy that can be exploited.
Aug 16	accepted	Are there lists of most common words or ngrams used in passwords and passphrases?

Aug 15	comment	Are there lists of most common words or ngrams used in passwords and passphrases? Thank you but what is "pentesting"?
Aug 12	comment	Are there lists of most common words or ngrams used in passwords and passphrases? @D.W.: Thanks I'm just getting up to speed. I was going to ask about Markov chains and HMMs next. Do you know where I can read something a little technical about how they use them?
