Yet another simple passphrase generator. See this XKCD for an explanation.

$ npm install correcthorsebatterystaple

var chbs = require('correcthorsebatterystaple');
new chbs();

You can configure the behavior by passing an options object:

new chbs({
    min: 15, // Mininum number of characters in returned passphrase. Default 20.
    max: 25, // Maximum number of characters in returned passphrase. Default 30.
    words: "enable.txt" // Use a different word list. Default "up-goer-five.txt".
});

When specifying a wordlist, if the file isn't found at the path specified, the code will fall back to checking the built-in wordlist directory for a file with the given name.

By default, the generated passphrase is sent to console.log. You can change this by passing a callback:

new chbs(function (pwd) {
    doSomethingWith(pwd);
});

new chbs({
    min: 16,
    max: 24
}, function (pwd) {
    doSomethingElseWith(pwd);
});

$ ./chbs
