**Backports hash_* functionality to older PHP versions.**


## Install

Via Composer

``` bash
$ composer require indigophp/hash-compat
```

You can safely install this package on systems, where these functions already exist, there won't be any conflict.

Since these functions have no dependencies, you can also include `src/{FUNCTION_NAME}.php` in your project.


## Usage

The backported functions provide the same functionality as the built-in in every way.

Currently supported functions:
- [hash_equals](http://php.net/manual/en/function.hash-equals.php)
- [hash_pbkdf2](http://php.net/manual/en/function.hash-pbkdf2.php)


## Testing
