The Release Process
===================

[](#the-release-process)

The release process [is described here](doc/Release.md).

Prerequisites
=============

[](#prerequisites)

This library needs at least [![PHP 5.4+](https://camo.githubusercontent.com/d99081cd5ddc5e37f8911ad464cb5dc3442d86b2eb940a05bbdeb0a16a3599ae/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f5048502d352e342532422d6666363962342e737667)](https://camo.githubusercontent.com/d99081cd5ddc5e37f8911ad464cb5dc3442d86b2eb940a05bbdeb0a16a3599ae/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f5048502d352e342532422d6666363962342e737667).

It has been successfully tested using `PHP 5.4` to `PHP 7.1`, `HHVM` and nightly branches.

If you use PHP 7.1+, this library has very good performance. **If you do not use PHP 7.1+, we highly recommend you to install the [PHP Crypto extension](https://github.com/bukka/php-crypto).**This extension drastically increase the performance of this library. With our pure PHP method, you will have low performance.

Installation
============

[](#installation)
