chbs

An implementation of https://xkcd.com/936/, the "correct horse battery staple" comic.

Pick four random, common words and string them together to make a very strong but easy to remember password.

The included corpora (word lists):

• tv-and-movies: The most common words in TV and movie scripts
• gutenberg: The most common words from Project Gutenberg, gives your passwords a bit more of an old-timey feel.
• babynames: The top 1000 boy and girl names from the US Social Security Administration.
• coca: The top 5000 words from the Corpus of Contemporary American English

Installation

$ gem install chbs

Usage

Running chbs with no options will be sufficient in most cases.

$ chbs
feeding-escape-toward-accused

You can try decreasing the max rank, -R 1000 for example, to get more common words and thus more easily remembered passwords. You can also have chbs generate a bunch of passwords, -c 5 for example, and pick one that you like.

$ chbs -R 1000 -c 5
