Installation

Install with bower:
``bash
bower install zxcvbn angular-zxcvbn
`

Include the following javascript source files:
`html


`

Add zxcvbn as an angular dependency. E.G. If your module is called myApp then you would do:
`javascript
angular.module('myApp', ['zxcvbn']);
`

Usage

##### Attribute

Live plunker:

The main way to use the directive is as an attribute alongside the ng-model attribute:
`html

`
This will set $scope.passwordStrength to the result of calling the zxcvbn function on
$scope.userPassword.

---
##### Extras

The directive has an optional attribute of zx-extras. This takes either an array or an angular form object, which will be passed as the optional argument to the zxcvbn call.

> The optional argument is an array of strings that zxcvbn will treat as an extra dictionary. This can be whatever list of strings you like, but is meant for user inputs from other fields of the form, like name and email. That way a password that includes a user's personal information can be heavily penalized. This list is also good for site-specific vocabulary — Acme Brick Co. might want to include ['acme', 'brick', 'acmebrick', etc].
-- zxcvbn readme.md

Example:
`html










`
We pass zx-extras the value myForm, which is the value of the name attribute of the parent

element.

angular-zxcvbn will look at all elements with name and ng-model attributes inside the element - *ignoring
fields with 'password' in their name*. Found fields are then used as the extras parameter in the zxcvbn call.

Note: if you do not wish to pass in a form object, you can also pass a scope variable that is an array of strings.

---
##### Form Validation

If you are using the AngularJS form directive you may also want to have the password field marked as
invalid when below a certain score.

This can be done by passing a zx-min-score attribute, which takes an integer between 0 and 4 inclusive. For example: zx-min-score="2"
would invalidate passwords with scores 0 or 1.

`html

`

You can also pass an interpolated scope value: zx-min-score="{{ minScore }}"

---


$3

You can use the directive as an element. The element takes 3 attributes:
* passwordrequired - the password that you want to be tested (scope variable).
extrasoptional - an array of strings that zxcvbn will use to get a better "crack time" estimate. Here you would normally have other form fields such as name, email address, username...*
dataoptional* - a scope object that will contain the returned data from the zxcvbn call.
