sfPasswordStrengthPlugin plugin
The sfPasswordStrengthPlugin allows you to easily measure the strength of a password.
It is displayed as a pretty progress bar.
Inspired from Password Strength validator snippet
Uses Alix Axel algorithm
Installation
Install the plugin
symfony plugin-install http://plugins.symfony-project.com/sfPasswordStrengthPlugin
Create a symbolic link
$ cd web
$ ln -s ../plugins/sfPasswordStrengthPlugin/web sfPasswordStrengthPlugin
Create an action
public function executeCalculateStrength()
{
$strength = PasswordStrength::calculate(
$this->getRequestParameter('passwd'),
$this->getRequestParameter('login')
);
return $this->renderText(PasswordStrength::getBar($strength));
}
Add a DIV element where the bar will be placed and observe your field (note: you can see that the login is sent too,
in order to test if the login is in the password, which is very bad!)
echo observe_field('passwd', array(
'update' => 'strength',
'url' => 'user_account/calculateStrength',
'with' => "$('passwd').serialize() + '&' + $('login').serialize()",
'script' => true,
'frequency'=> 0.5,
));
Insert the style sheet (I hope this step will be automated soon!)
<?php use_stylesheet('/sfPasswordStrengthPlugin/css/sfPasswordStrengthStyle.css'); ?>
You should be done.
