Purchase License

Purchase:

Once your purchase is complete you will be returned to this page. You will not receive any confirmation emails of a license key - licensing is done in good faith.

Your Setup

Your users' passwords are only as secure as the system in which they are used. Make sure your system handles passwords securely before including How Secure Is Their Password? on your site.

Usage

HTML

<input type="password" id="password" />
<p id="result"></p>

Make sure you include a reference to hsitp.min.js somewhere on your page (it is good practice to put <script> tags at the bottom of your page).

JS

var password = document.getElementById('password'),
        result = document.getElementById('result');

    hsitp(password, result, { namedNumber: false });

The password element should be an <input> of some sort (probably of type="password"). The result element can be anything, most likely a <p> or <span>.

It can also take jQuery objects if that's your preference:

var password = $('#password'),
    result = $('#result');

hsitp(password, result, { namedNumber: false });

Currently, if jQuery returns more than one element (e.g. $('input') on a page with multiple inputs) only the first will be used.

hsitp.min.js can be used with AMD loaders (e.g. RequireJS). If the define function is present in your codebase the hsitp function will not be made global and the AMD system should be used instead.

Configuration Options

Example

hsitp(password, result, {
    calculations: "4 billion",
    checksCallback: function (checks) {
        console.log(checks);
    },
    checksElem: document.getElementById('checks'), // or $('#checks')
    checksMessage: true,
    namedNumbers: true
});
