Getting The Code
|
|
=================
|
|
|
|
There are two ways to use this library in your applications. You can either:
|
|
|
|
1. Use [Composer](https://getcomposer.org/), or
|
|
2. `require_once` a single `.phar` file in your application.
|
|
|
|
If you are not using either option (for example, because you're using Git submodules), you may need to write your own autoloader ([example](https://gist.github.com/paragonie-scott/949daee819bb7f19c50e5e103170b400)).
|
|
|
|
Option 1: Using Composer
|
|
-------------------------
|
|
|
|
Run this inside the directory of your composer-enabled project:
|
|
|
|
```sh
|
|
composer require defuse/php-encryption
|
|
```
|
|
|
|
Unfortunately, composer doesn't provide a way for you to verify that the code
|
|
you're getting was signed by this library's authors. If you want a more secure
|
|
option, use the `.phar` method described below.
|
|
|
|
Option 2: Including a PHAR
|
|
----------------------------
|
|
|
|
The `.phar` option lets you include this library into your project simply by
|
|
calling `require_once` on a single file. Download `defuse-crypto.phar` and
|
|
`defuse-crypto.phar.sig` from this project's
|
|
[releases](https://github.com/defuse/php-encryption/releases) page.
|
|
|
|
You should verify the integrity of the `.phar`. The `defuse-crypto.phar.sig`
|
|
contains the signature of `defuse-crypto.phar`. It is signed with Taylor
|
|
Hornby's PGP key. You can find Taylor's public key in `dist/signingkey.asc`. You
|
|
can verify the public key's fingerprint against the Taylor Hornby's [contact
|
|
page](https://defuse.ca/contact.htm) and
|
|
[twitter](https://twitter.com/DefuseSec/status/723741424253059074).
|
|
|
|
Once you have verified the signature, it is safe to use the `.phar`. Place it
|
|
somewhere in your file system, e.g. `/var/www/lib/defuse-crypto.phar`, and then
|
|
pass that path to `require_once`.
|
|
|
|
```php
|
|
<?php
|
|
|
|
require_once('/var/www/lib/defuse-crypto.phar');
|
|
|
|
// ... the Crypto, File, Key, and KeyProtectedByPassword classes are now
|
|
// available ...
|
|
|
|
// ...
|
|
```
