I used this concept a while back to generate 7-word passphrases with 84 bits of entropy. I picked a list of popular words and filtered it down to 4270 that are reasonably short and memorable: https://raw.githubusercontent.com/dbasch/clj-brainwallet/master/words.txt https://raw.githubusercontent.com/dbasch/clj-brainwallet/mas... Here's a browser implementation. I wouldn't use it (do you trust your browser's prng? Do you trust my code?) but it's fun to see the passphrases it generates, and how easy it is to create a story to remember them. http://diegobasch.com/passgen/ http://diegobasch.com/passgen/ Same thing applied to generating bitcoin brainwallets. Once again, don't use this. It was just a fun experiment to see if I could keep money in my brain. http://diegobasch.com/brainwallet/ http://diegobasch.com/brainwallet/
