PasswordStrengthAnalyzer
========================

[](#passwordstrengthanalyzer)

[![Tests](https://github.com/yarri/PasswordStrengthAnalyzer/actions/workflows/tests.yml/badge.svg)](https://github.com/yarri/PasswordStrengthAnalyzer/actions/workflows/tests.yml)[![Downloads](https://camo.githubusercontent.com/fc277976e522f834734799dbcc3e3231b71a81075bca8e46d36b3e92065e6cb7/68747470733a2f2f696d672e736869656c64732e696f2f7061636b61676973742f64742f79617272692f70617373776f72642d737472656e6774682d616e616c797a65722e737667)](https://packagist.org/packages/yarri/password-strength-analyzer)

Scores password strength from 0% to 100%, penalizing repeated patterns and consecutive character sequences. Unicode and diacritics are supported.

Usage
-----

[](#usage)

```
$analyzer = new Yarri\PasswordStrengthAnalyzer();
$score = $analyzer->analyze("someFAIRpasswd"); // 26

```

Passwords with letters, numbers, and symbols are rated high.

```
echo $analyzer->analyze("SomW2!3RE#"); // 91

```

Letter-only passwords can also score high if they are long enough.

```
echo $analyzer->analyze("someBOYS"); // 9
echo $analyzer->analyze("someBOYSdontCRY"); // 38
echo $analyzer->analyze("someBOYSdontCRYmuch"); // 71

```

But not all long passwords are rated high.

```
echo $analyzer->analyze("somesomesomesomesomesome"); // 4

```

Groups of 3 or more consecutive characters have a negative impact on the final score.

```
echo $analyzer->analyze("Secret18239!"); // 58
echo $analyzer->analyze("Secret12345!"); // 45
echo $analyzer->analyze("Secret76543!"); // 45

echo $analyzer->analyze("OpenAFBGCED!"); // 42
echo $analyzer->analyze("OpenABCDEFG!"); // 30

```

Use `getCoefficients()` to inspect the individual scoring factors after an analysis:

```
$analyzer->analyze("SomW2!3RE#"); // 91
print_r($analyzer->getCoefficients());
// [
//   'unique_chars'      => 2,
//   'password_length'   => 1,
//   'types_used'        => 1.0125,
//   'type_transitions'  => 0.8958,
//   'simplicity_factor' => 1,
// ]

```
