# Zxcvbn for Laravel 5
[![Latest Version on Packagist][ico-version]][link-packagist]
[![Software License][ico-license]](LICENSE.md)
[![Build Status][ico-travis]][link-travis]
A simple implementation of zxcvbn for Laravel 5. This package allows you to access "zxcvbn-related" data on a passphrase in the application, but also use zxcvbn as a standard validator.
Uses [Zxcvbn-PHP](https://github.com/bjeavons/zxcvbn-php) by [@bjeavons](https://github.com/bjeavons), which in turn is inspired by [zxcvbn](https://github.com/dropbox/zxcvbn) by [@dropbox](https://github.com/dropbox).
## Install
Via Composer
``` bash
$ composer require olssonm/l5-zxcvbn
```
Add the package to your providers array:
``` php
'providers' => [
Olssonm\Zxcvbn\ZxcvbnServiceProvider::class,
]
```
If you wish to have the ability to use `Zxcvbn` via dependency injection, or just have a quick way to access the class add an alias to the facades:
``` php
'aliases' => [
'Zxcvbn' => Olssonm\Zxcvbn\Facades\Zxcvbn::class
]
```
## Usage
If you've added `Olssonm\Zxcvbn` as an alias, your can access Zxcvbn easily from anywhere in your application:
### "In app"
``` php
<?php
use Zxcvbn;
class MyClass
{
public function myFunction()
{
$zxcvbn = Zxcvbn::passwordStrength('password');;
dd($zxcvbn->passwordStrength('password'));
// array:6 [
// "crack_time" => 5.0E-5
// "calc_time" => 0.1857271194458
// "password" => "password"
// "entropy" => 0.0
// "match_sequence" => array:1 []
// "score" => 0
// ]
}
}
?>
```
Play around with different passwords and phrases, the results may surprise you. Check out [Zxcvbn-PHP](https://github.com/bjeavons/zxcvbn-php) for more uses and examples.
### As a validator
The package gives you two different validation rules that you may use; `zxcvbn_min` and `zxcvbn_dictionary`.
#### zxcvbn_min
`zxcvbn_min` allows you to set up a rule for minimum score that the value beeing tested should adhere to.
***Syntax***
`'input' => 'zxcvbn_min:min_value'`
``` php
<?php
$data = ['password' => 'password'];
$validator = Validator::make($data, [
'password' => 'zxcvbn_min:3|required',
], [
'password.zxcvbn_min' => 'Your password is not strong enough!'
]);
```
In this example the password should at least have a "score" of three (3) to pass the validation. Of course, you should probably use the zxcvbn-library on the front-end too to allow the user to know this before posting the form...
#### zxcvbn_dictionary
This is a bit more interesting. `zxcvbn_dictionary` allows you to input both the users username and/or email, and their password. The validator checks that the password doesn't exist in the username, or that they are too similar.
***Syntax***
`'input' => 'xcvbn_dictionary:username,email'`
``` php
<?php
/**
* Example 1, pass
*/
$password = '31??2sa//"dhjd2askjd19sad19!!&!#"';
$data = [
'username' => 'user',
'email' => 'trash@thedumpster.com'
];
$validator = Validator::make($password, [
'password' => 'zxcvbn_dictionary:' . $data['username'] . ',' . $data['email'] . '|required',
]);
dd($validator->passes());
// true
/**
* Example 2, fail
*/
$password = 'mycomplicatedphrase';
$data = [
'username' => 'mycomplicatedphrase',
'email' => 'mycomplicatedphrase@thedumpster.com'
];
$validator = Validator::make($password, [
'password' => 'zxcvbn_dictionary:' . $data['username'] . ',' . $data['email'] . '|required',
]);
dd($validator->passes());
// false
```
## Testing
``` bash
$ composer test
```
or
``` bash
$ phpunit
```
