The Pwdcheck
tool uses the Wolfram Alpha method for estimating the strength of a password.
It goes through a set of several checks to give the password a "score":
- 0-60: Very Weak
- 60-70: Weak
- 70-80: Fair
- 80-90: Strong
- 90-100: Very Strong
You can use Composer to install Pwdcheck
:
{
"require": {
"psecio/pwdcheck": "1.*"
}
}
Usage of the tool is simple and you can either fetch the text version of the strength (ex. "Very Weak") or a numeric representation from zero through four:
<?php
require_once 'vendor/autoload.php';
$p = new \Psecio\Pwdcheck\Password();
$p->evaluate($password);
// getting the numeric representation:
echo 'Strength: '.$p->getStrength()."\n";
// getting the text version:
echo 'Strength: '.$p->getStrength(true)."\n";
// you can also get the raw score either as a return value or using getScore
$result = $p->evaluate($password);
echo 'Score: '.$result."\n"
echo 'Score: '.$p->getScore()."\n";
