This component provides compatibility for the [`hash_pbkdf2()`](http://php.net/manual/en/function.hash-pbkdf2.php)function on PHP versions >=5.3,<5.5.

Install
-------

[](#install)

Via Composer

```
$ composer require rych/hash_pbkdf2-compat
```

Usage
-----

[](#usage)

When loaded via Composer on PHP versions <5.5, a global function `hash_pbkdf2()` is automatically loaded which matches the >=5.5 built-in function as closely as possible. On PHP versions >=5.5, the shim function is available as `\Rych\hash_pbkdf2()`.

If not using Composer, make sure to include `src/hash_pbkdf2-compat.php` in order to load the function.

See the PHP documentation for [`hash_pbkdf2()`](http://php.net/manual/en/function.hash-pbkdf2.php) for information.

Testing
-------

[](#testing)

```
$ composer test
```
