ntropy.js

Description

ntropy.js is a random string/number generator using entropy collected from mouse movement or device motion as the seed for random content.

It can be used as way for users to generate passwords for themselves, generate password salts during account registration, or even manual session ID creation. There are other possible uses, generating encryption keys, and so on.

Usage

The usage is rather simple. Just point the plugin to the target input field.

    ntropy({limit: 10, pool: "abcdefghijklmnopqrstuvwxyz"}, function (random) {
        console.log(random);
    });

After the random string is generated, the callback is executed.

Demo

Options

The options object has the following two properties:

limit - the length of the generated string pool - the characters used to generate the string (i.e. 'abcdefghijklmopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890'
