No, the logic of the article is "now that she knows that I cheated I am forced to continue cheating forever, because F**K HER what makes her think she has a say. Because the guy who told on me is a traitor and we can't reward traitors. Also I'll send him to the hospital if he comes out of hiding"

That's the logic of the article.

So the principle is "the public must be denied all power!"???

How did Snowden force their hand, since they're refusing to end the data collection program? He forced them to keep it? Because now that the public knows, the public must be denied freedom at all costs? Because F**K the public, keep the public from having any say is the principle?

characters. Because the entropy of one word out of 7776 is almost as high as two english keyboard characters. So any, say 7 word passphrase could be shortened to a 14 character password without losing any entropy.

But you'd need a program to convert between the two.

You miss the point, doubling the number of words only gives you one more bit per word, but makes looking up a word from dice too hard.

To be more specific, this dictionary is about 9 bits per word. If you used a 100,000 word webster's dictionary that's about 11 bits per word - it's not that many more bits.

The advice is only wrong that he said "common words" and didn't give a random procedure for picking - the size of the dictionary matters, and expecting humans to be random without some help isn't reliable. If he said "take a paper dictionary, open it a random page and finger position and pick a word 5 times" he'd have extremely good advice.

Uhm you didn't understand what I typed.

If you pick 7 different words at random from a dictionary of 100,000 words and make a sentence from them you have log(100,000 choose 7)/log(2) bits of entropy that's 104 bits.

You'll never be able to remember a random character password worth 104 bits. Never. But you could remember a 7 word sentence.

entropy is, and how to measure it. Then we will solve the problem. Oh my God there is nothing worse than what passes for good passwords. People are good at remembering sentences and those have lots of entropy. People are terrible at remembering what we call passwords and those have very little.

We're just doing this wrong from beginning to end.
