Password Strength Tester

A simple and fast password strength tester inspired by WolframAlpha's Calculation

Usage

$scorer = \Siteworx\Passwords\Scorer::score('SuperPassword!');

echo json_encode($scorer->toArray());

will output and is great for an ajax endpoint

You can also access several helper methods

if ($scorer->isExcellent()) {
    echo 'Your password is excellent :)';
}
if ($scorer->isPoor()) {
    echo 'Your password is poor :(';
}

or

echo 'Your Password is ' . $scorer->stringValue();

Your Password is Poor

Bias

You can also provide a bias to the scorer if you want your passwords to be scored higher or lower.

Pass in a value between -5 to 5.

$scorer = \Siteworx\Passwords\Scorer::score('N0wAStrongPassword!', -5);
echo 'This password is ' . $scorer->stringValue();
$scorer = \Siteworx\Passwords\Scorer::score('N0wAStrongPassword!', 0);
echo 'This password is ' . $scorer->stringValue();
$scorer = \Siteworx\Passwords\Scorer::score('N0wAStrongPassword!', 5);
echo 'This password is ' . $scorer->stringValue();

This password is Poor
This password is Fair
This password is Very Strong
