Usage

Policy Builder

$builder = new \PasswordPolicy\PolicyBuilder(new \PasswordPolicy\Policy);
$builder->minLength(6)
    ->upperCase();

Any of the following methods may be chained on the builder class to build your password policy.

minLength(length)

length

Type: int

Minimum number of characters the password must contain.

maxLength(length)

length

Type: int

Maximum number of characters the password must contain.

upperCase([min])

min

Type: int

Minimum number of upper case characters the password must contain.

lowerCase([min])

min

Type: int

Minimum number of lower case characters the password must contain.

digits([min])

min

Type: int

Minimum number of numeric characters the password must contain.

specialCharacters([min])

min

Type: int

Minimum number of special characters the password must contain.

doesNotContain(phrases [,phrases])

phrases

Type: string|array

Phrases that the password should not contain

Example

->doesNotContain('password', $firstName, $lastName)

minPassingRules(passesRequired, ruleSet)

passesRequired

Type: int

The minimum number of rules in the ruleSet that need to pass, in order for this rule to pass

ruleSet

Type: \Closure

A closure which is given a new PolicyBuilder instance.

Example

// One of these rules must pass
->minPassingRules(1, function (PolicyBuilder $builder) {
    $builder->doesNotContain('password')
        ->minLength(10);
})

Laravel

If you are a Laravel user, this package can seamlessly integrate with your validators.

Install Package

Begin by adding the below service provider.

// config/app.php

'providers' => [
    // ...
    \PasswordPolicy\Providers\Laravel\PasswordPolicyServiceProvider::class,
],

Define Policies

Within an app service provider (e.g. AppServiceProvider.php) you can start defining password policies.

// App/Providers/AppServiceProvider.php

// use PasswordPolicy\PolicyBuilder;
 

/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    \PasswordPolicy::define('default', function (PolicyBuilder $builder) {
        $builder->minLength(8)
            ->upperCase(3);
            // ...
    });
}

You can define as many policies as you require, however it's recommended to stick with 'default' when possible.

Setup Validation

Once you're policies have been defined, you're ready to start using the policies. A new 'password' validation rule is now available to use.

// Request class

/**
 * Declare validation rules
 * 
 * @return array
 */
public function rules()
{
    return [
        // ...
        'password' => 'required|password'
    ];
}

The validator will use the 'default' policy by default. To use an alternative policy, add an additional parameter:

'password' => 'required|password:admin'
